As nosotros go along to learn more nearly coronavirus and COVID-19, it can help to reacquaint yourself with some basic information. For instance, agreement how the virus spreads reinforces the importance of prevention measures. Knowing how COVID has impacted people of all ages may reinforce the need for everyone to prefer wellness-promoting behaviors. And reviewing the common symptoms of COVID-xix tin help yous know if it'south fourth dimension to get tested and self-isolate.

What is coronavirus?

Coronaviruses are an extremely common crusade of colds and other upper respiratory infections. SARS-CoV-ii, brusque for astringent acute respiratory syndrome coronavirus 2, is the official proper name for the coronavirus responsible for COVID-19.

What is COVID-nineteen?

COVID-19, short for "coronavirus disease 2019," is the name of the illness caused by the SARS-CoV-two coronavirus.

How many people have COVID-xix?

The numbers are changing apace.

The about up-to-date data is bachelor from the World Health Organization, the United states of america Centers for Disease Control and Prevention, and Johns Hopkins Academy.

In March 2020, the World Health Organization declared COVID-xix a pandemic (a term indicating that it has affected a large population, region, country, or continent).

Do adults younger than 65 who are otherwise salubrious need to worry about COVID-19?

Yes, they do. Although the run a risk of serious illness or death from COVID-xix increases steadily with age, younger people can become sick enough from the disease to require hospitalization. And certain underlying medical conditions may increase the risk of serious COVID-nineteen for individuals of any age.

Everyone, including younger and healthier people, should get the vaccine one time they are eligible, to protect both themselves and their community. Vaccines offer excellent (though not complete) protection against moderate to severe disease, hospitalization, and death.

In addition, the CDC advises everyone — vaccinated and unvaccinated — to wearable masks in public indoor places in areas of the country with substantial or high transmission of the virus. The CDC likewise advises anyone at increased risk to wear a mask indoors, regardless of the level of community transmission. For people who are not fully vaccinated, the CDC continues to recommend mask wearing and other preventive measures such as physical distancing in some outdoors settings and in most indoor settings.

To check the level of virus transmission in your area, visit the CDC's COVID Data Tracker.

To what extent have younger adults been impacted past COVID-19?

Co-ordinate to the CDC'due south COVID Information Tracker, through mid-Nov 2021, well-nigh 38% of COVID cases in the U.s. take been in adults anile 18 to 39 years. Still, younger adults are less probable than older adults to die of COVID-19: Adults in the 18 to 39 age range account for near 2.4% of COVID deaths, compared to 76.viii% for people older than 65.

Simply younger peopletin get sick enough from the disease to require hospitalization or to die. And they may be amid the long haulers — people who continue to feel fatigue, brain fog, shortness of breath, or other symptoms weeks and months subsequently their illness.

And as is true in other age groups, COVID affliction and decease has a asymmetric impact on younger adults of color.

Everyone, including younger and healthier people, should become the vaccine once they are eligible.

What are the symptoms of COVID-19?

Some people infected with the virus have no symptoms. When the virus does cause symptoms, common ones include fever, body ache, dry out cough, fatigue, chills, headache, sore throat, loss of appetite, and loss of odour. In some people, COVID-nineteen causes more astringent symptoms similar high fever, severe cough, and shortness of jiff, which oft indicates pneumonia.

People with COVID-nineteen can too experience neurological symptoms, gastrointestinal (GI) symptoms, or both. These may occur with or without respiratory symptoms.

For example, COVID-19 affects encephalon function in some people. Specific neurological symptoms seen in people with COVID-19 include loss of aroma, inability to taste, muscle weakness, tingling or numbness in the hands and feet, dizziness, defoliation, delirium, seizures, and stroke.

In addition, some people have gastrointestinal (GI) symptoms, such every bit loss of ambition, nausea, airsickness, diarrhea, and intestinal pain or discomfort associated with COVID-19.

How soon tin a person exposed to the virus expect symptoms to start?

On average, the fourth dimension from exposure to symptom onset (known every bit the incubation flow) is about five to six days. However, studies have shown that symptoms could announced equally soon every bit 3 days afterward exposure to as long as 13 days later.

Can COVID-19 symptoms worsen apace after several days of illness?

Common symptoms of COVID-xix include fever, dry cough, fatigue, loss of appetite, loss of smell, and body ache. In some people, COVID-19 causes more severe symptoms like high fever, astringent cough, and shortness of jiff, which frequently indicates pneumonia.

A person may have mild symptoms for nearly one week, and so worsen rapidly. Permit your doctor know if your symptoms quickly worsen over a brusque period of time. Likewise call the doctor right away if you or a loved one with COVID-19 experience any of the following emergency symptoms: trouble breathing, persistent pain or force per unit area in the breast, confusion or inability to arouse the person, or bluish lips or face.

One of the symptoms of COVID-xix is shortness of breath. What does that mean?

Shortness of breath refers to unexpectedly feeling out of breath, or winded. But when should you worry near shortness of breath? There are many examples of temporary shortness of breath that are not worrisome. For instance, if you lot feel very anxious, it's common to become curt of breath and then it goes abroad when you at-home down.

However, if y'all find that you are ever breathing harder or having problem getting air each fourth dimension you exert yourself, you always need to telephone call your doctor. That was truthful before we had COVID-xix, and information technology will still exist true after information technology is over.

Is a lost sense of odour a symptom of COVID-19? What should I do if I lose my sense of odor?

A lost sense of smell, known medically equally anosmia, is a common symptom of COVID-19. This is not surprising, because viral infections are a leading cause of loss of sense of smell, and COVID-nineteen is a caused by a virus. Still, loss of smell with COVID-nineteen appears to occur much more often compared to other viral infections. And then, this symptom may assist doctors identify people who do not have other symptoms, but who might be infected with the COVID-xix virus — and who might be unwittingly infecting others.

In addition to COVID-xix, loss of aroma can also result from allergies as well as other viruses, including rhinoviruses that cause the common cold. And so anosmia alone does not mean yous have COVID-19.

Tell your doctor right abroad if yous find yourself newly unable to odor. He or she may prompt yous to get tested and to self-isolate.

A Nov 2022 report published in JAMA Otolaryngology – Head and Cervix Surgery found that between 700,000 and 1.six one thousand thousand people in the U.s.a. have experienced COVID-related loss or dumb sense of smell that lasted more than six months.

In nearly all cases, however, sense of smell returns within one year. A report of nigh 100 COVID patients who lost their sense of olfactory property constitute that 86% recovered their sense of olfactory property by six months later infection, and 96% recovered their sense of olfactory property inside 12 months after infection.

What are cytokine storms and what do they accept to do with COVID-xix?

A cytokine storm is an overreaction of the body'southward immune system. In some people with COVID-nineteen, the allowed arrangement releases immune messengers, chosen cytokines, into the bloodstream out of proportion to the threat or long after the virus is no longer a threat.

When this happens, the immune system attacks the torso's own tissues, potentially causing significant harm. A cytokine tempest triggers an exaggerated inflammatory response that may harm the liver, blood vessels, kidneys, and lungs, and increase formation of blood clots throughout the trunk. Ultimately, the cytokine storm may crusade more harm than the coronavirus itself.

A simple blood test can aid make up one's mind whether someone with COVID-19 may exist experiencing a cytokine storm. Many doctors, including those in the U.s., accept been treating very ill COVID-19 patients with dexamethasone and other corticosteroids (prednisone, methylprednisolone). Corticosteroids are stiff anti-inflammatory drugs and thus brand biologic sense for those patients who have developed an exaggerated inflammatory response to the viral infection.

Does COVID-19 cause strokes? What well-nigh blood clots in other parts of the body?

Strokes occur when the encephalon's blood supply is interrupted, usually past a blood jell. There accept been reports of a greater-than-expected number of younger patients being hospitalized for, and sometimes dying from, serious strokes. These strokes are happening in patients who test positive for coronavirus but who do non take whatever traditional risk factors for stroke. They tend to have no COVID-19 symptoms, or only mild symptoms. The blazon of stroke occurring in these patients typically occurs in much older patients.

COVID-related strokes occur because of a trunk-broad increase in claret clot formation, which can impairment whatever organ, not just the brain. A blood jell in the lungs is called pulmonary embolism and can cause shortness of jiff, breast pain, or death; a blood clot in or well-nigh the heart can cause a center attack; and blood clots in the kidneys tin can crusade kidney damage requiring dialysis.

Ane possible reason for COVID-related blood clots may be a disturbance in the levels of a protein, called factor 5, that is involved in blood clotting.

Can COVID-19 affect encephalon function?

COVID-19 does appear to impact brain part in some people. Specific neurological symptoms seen in people with COVID-19 include loss of aroma, inability to gustatory modality, muscle weakness, tingling or numbness in the easily and feet, dizziness, confusion, delirium, seizures, and stroke.

1 study that looked at 214 people with moderate to severe COVID-19 in Wuhan, Cathay constitute that well-nigh 1-3rd of those patients had one or more neurological symptoms. Neurological symptoms were more than mutual in people with more than severe disease.

Neurological symptoms have likewise been seen in COVID-19 patients in the Usa and around the world. Some people with neurological symptoms tested positive for COVID-19 but did not have any respiratory symptoms similar coughing or difficulty breathing; others experienced both neurological and respiratory symptoms.

Experts do not know how the coronavirus causes neurological symptoms. They may be a straight outcome of infection or an indirect outcome of inflammation or contradistinct oxygen and carbon dioxide levels caused by the virus.

"New confusion or disability to rouse" is on the CDC'due south list of emergency alarm signs that should prompt you to get immediate medical attention.

How does coronavirus spread?

The coronavirus spreads mainly from person to person. A person infected with coronavirus — even 1 with no symptoms — may emit aerosols when they talk or breathe. Aerosols are infectious viral particles that tin can float or drift around in the air for upwardly to three hours. Another person can breathe in these aerosols and get infected with the coronavirus.

When people are in shut contact with one another, droplets that are produced when an infected person coughs or sneezes may country in the mouths or noses of people who are nearby, or perchance be inhaled into their lungs.

Transmission is less likely to happen outdoors, where air currents scatter and dilute the virus, than in a abode, office, or other bars space with express air circulation.

The gamble of spread from contact with contaminated surfaces or objects is considered to be extremely low. According to the CDC, each contact with a contaminated surface has less than a 1 in x,000 chance of causing an infection.

The virus may be shed in saliva, semen, and feces; whether information technology is shed in vaginal fluids isn't known. Kissing can transmit the virus. Transmission of the virus through feces, or during vaginal or anal intercourse or oral sex, appears to exist extremely unlikely at this fourth dimension.

I'yard vaccinated only got a breakthrough COVID infection. Tin can I still spread the infection to others?

Yes, y'all tin. That's why the CDC recommends that anybody who tests positive for COVID-xix should isolate from others for at least five days, regardless of their vaccination status.

Tin people without symptoms spread the virus to others?

"Without symptoms" tin can refer to two groups of people: those who eventually do have symptoms (pre-symptomatic) and those who never go on to have symptoms (asymptomatic). During this pandemic, we accept seen that people without symptoms can spread the coronavirus infection to others.

A person with COVID-19 may be contagious 48 hours before starting to experience symptoms. In fact, people without symptoms may be more likely to spread the illness, considering they are unlikely to be isolating and may not adopt behaviors designed to forestall spread.

But what well-nigh people who never go on to develop symptoms? A study published in JAMA Network Open up found that almost i out of every 4 infections may be transmitted by individuals with asymptomatic infections. The proportion of asymptomatic transmission appears to be fifty-fifty college with the Omicron variant.

Getting vaccinated and additional one time you are eligible is important for protecting not but yourself but others as well; evidence suggests that you're less likely to infect others, or may be contagious for a shorter period of time, once you've been vaccinated.

Are kids any more or less probable than adults to spread coronavirus?

Most children who go infected with the COVID-nineteen virus take no symptoms, or they have milder symptoms such as low-grade fever, fatigue, and cough. Early studies suggested that children do not contribute much to the spread of coronavirus. Merely more than recent studies indicate that children are capable of spreading the infection.

Though the studies varied in their methods, their findings were similar: infected children had as much, or more, coronavirus in their upper respiratory tracts as infected adults. And a November 2022 study conducted past Harvard researchers once more confirmed that children carry alive virus capable of infecting others.

The amount of virus found in children — their viral load — was not correlated with the severity of their symptoms. In other words, a child with mild or no symptoms may have just as many viral particles in their nose and mouth as a child that has more severe symptoms. So, the presence of a loftier viral load in infected children increases the likelihood that children, even those without symptoms, could readily spread the infection to others.

The bottom line? Public wellness measures are as important for kids and teens equally they are for adults.

What does the CDC's definition of "close contacts" mean for me?

The CDC defines a close contact equally someone who spends 15 minutes or more within six feet of a person with COVID-nineteenover a menstruation of 24 hours.

Shut contacts are at increased risk of infection. When a person tests positive for COVID-nineteen, contact tracers may place their shut contacts and notify them that they take been exposed.

Many factors tin affect the chances that infection will spread from ane person to another. These factors include whether or one or both people are wearing masks, whether the infected person is cough or showing other symptoms, and whether the meet occurred indoors or outdoors.

How could contact tracing help deadening the spread of COVID-19?

Anyone who comes into close contact with someone who has COVID-xix is at increased chance of becoming infected themselves, and of potentially infecting others. Contact tracing can aid forbid further transmission of the virus by apace identifying and informing people who may be infected and contagious, so they can accept steps to not infect others.

Contact tracing begins with identifying everyone that a person recently diagnosed with COVID-nineteen has been in contact with since they became contagious. In the example of COVID-19, a person may be contagious 48 to 72 hours before they started to experience symptoms.

The contacts are notified nigh their exposure. They may be told what symptoms to look out for, advised on when to get tested for the virus, whether and for how long to isolate themselves, and to seek medical attention as needed if they kickoff to feel symptoms.

How long tin can the coronavirus stay airborne? I have read different estimates.

A written report washed by National Institute of Allergy and Infectious Diseases' Laboratory of Virology in the Division of Intramural Research in Hamilton, Montana helps to respond this question. The researchers used a nebulizer to blow coronaviruses into the air. They plant that infectious viruses could remain in the air for upwardly to three hours. The results of the study were published in theNew England Journal of Medicine on March 17, 2020.

Can the COVID-19 virus spread through air conditioning?

We don't know for sure if the COVID-nineteen virus spreads through air conditioning. Just nosotros do know that when it'south hot and humid, people are more likely to stay indoors, with the windows closed — giving the virus more opportunity to spread.

Coronavirus spreads through droplets that an infected person emits through coughs or sneezes and through smaller, infectious viral particles that tin drift around in the air for several hours. Outdoors, air currents can besprinkle and dilute the virus, making transmission less probable. You're more likely to inhale the virus indoors, with the windows airtight, whether or non you take the air workout on.

If y'all are indoors with anyone outside of your household, increase air circulation by keeping the windows open up equally much as possible.

Tin can I catch the coronavirus by eating nutrient handled or prepared by others?

According to the CDC, the risk of getting COVID-19 by handling or consuming nutrient from a restaurant, takeout, or drive-through is very low.

What is the naming system for COVID-xix variants?

The WHO announced a new naming arrangement for COVID-19 variants in May 2021. The new names are intended to be easier to pronounce and will remove the stigma of a variant'due south being associated with a particular country.

Under the new system, the variants will exist named using letters of the Greek alphabet. For example:

Blastoff is the new name for the B.1.1.7 variant, commencement documented in the United Kingdom.
Beta is the new proper name for the B.1.351 variant, first documented in South Africa.
The P.ane variant, beginning documented in Brazil, volition now be known as Gamma.
The B.one.617.2 variant, first documented in India, volition be called Delta.

For a complete list of new SARS-CoV-2 variant names, click here.

Scientists volition likely continue referring to variants by strings of letters and numbers, which provide information well-nigh a variant's lineage.

What do we know about the Omicron variant?

The Omicron variant, also known as B.1.1.529, is now the near common SARS-CoV-2 variant in the Usa. This variant has about 50 mutations, including more thirty mutations on the spike protein, the region of the virus that binds to and allows the virus to enter man cells. Hither's what we know well-nigh information technology.

How transmissible is Omicron?

Dr. Anthony Fauci, Chief Medical Advisor to the President of the The states, said in a White Business firm press briefing, "…we know now incontrovertibly that this is a highly, highly transmissible virus…" A report from the United kingdom of great britain and northern ireland found that someone infected with the Omicron variant is 3 times more probable to infect a member of their household than someone infected with the Delta variant. Co-ordinate to the CDC, most transmission occurs in the i to 2 days before symptoms begin and the 2 to three days after.

How well does Omicron evade protection from vaccines?

Several studies, including some presented at a WHO meeting in mid-Dec, have shown that two doses of an mRNA vaccine like Pfizer/BioNTech or Moderna practise not protect also against infection with Omicron as they did against previous SARS-CoV-2 variants.

One pocket-size laboratory report conducted past researchers in South Africa, for instance, found a 41-fold subtract in neutralization (the power of antibodies to prevent the virus from infecting cells) with Omicron compared to the earlier coronavirus variant. Pfizer/BioNTech as well released data from a laboratory report showing a significantly decreased antibiotic response to Omicron later on two vaccine doses.

This all suggests that Omicron is more capable of causing breakthrough infections (in people who are vaccinated) and reinfections (in people who were previously infected).

More promising findings from Pfizer/BioNTech showed that after three vaccine doses (2 doses plus a booster), the neutralizing antibiotic response was much stronger. Preliminary inquiry from the National Constitute of Allergy and Infectious disease'south Vaccine Research Center, conducted in the lab using the Moderna vaccine, similarly showed that boosters increment antibiotic-derived protection.

The benefit of boosters is as well being seen in the existent world. In one preprint report (not however peer-reviewed or published), researchers in the United Kingdom showed that protection confronting infection and balmy disease increased from virtually 40% 4 months after two Pfizer/BioNTech shots to well-nigh 75% within two weeks after a booster dose. This study took identify during a time when Omicron cases were rising in the Britain.

How might boosters aid? Booster-generated antibodies are not more specific to the Omicron variant. Merely the sheer increase in antibiotic levels helps enhance our immunity.

What's more, the vaccines keep to significantly protect against severe symptoms, hospitalization, and decease, specially for people who have received a booster. That'southward because in improver to stimulating an antibody response, vaccines also stimulate production of T cells, a blazon of immune cell that attacks infected cells. In a preprint study, an international team of researchers showed that the T cell response holds upwards well in people who are vaccinated or were previously infected with SARS-CoV-2. Specifically, the researchers institute that CD4 and CD8 T cells retained seventy% to lxxx% of their response to Omicron.

Is Omicron more or less virulent than previous variants?

Lab studies, animal studies, and epidemiological data all indicate that Omicron may crusade less severe illness than previous variants, and a few of the studies provide clues as to why that may be the case. A team of researchers in Hong Kong, for case, wrote in a preprint written report that the Omicron virus replicates more quickly in the bronchi (tubes that evangelize air from the windpipe to the lungs) than it does in the lungs themselves. This is meaning considering in one case in the lungs, the virus can lead to scarring and difficulty breathing, and trigger widespread inflammation. The Hong Kong report was conducted in a laboratory on homo tissue. Brute studies in mice and hamsters too evidence more viral replication in the upper airway compared to the lungs, and less clinical affliction (in these animals, that ways less weight loss, lung impairment, and expiry).

In real-earth findings, data from the United kingdom show pregnant reduction in the risk of hospitalization from Omicron compared to Delta, and information from the US show that even after accounting for a time lag, hospitalizations and deaths are not increasing in proportion to the increased number of infections.

In that location are probably many reasons for the reduced disease severity we're seeing, including some protection from vaccines and previous infections, as well as the likelihood that this variant inherently causes less severe disease than previous variants.

Still, 2 things are of import to consider: First, this variant is more transmissible, and so even if information technology is not as dangerous, it will lead to a larger number of astringent illnesses, hospitalizations, and deaths, based simply on the increased number of people it infects. And 2nd, the run a risk of severe affliction with Omicron is much higher in people who are not vaccinated.

Which preventive health measures are effective?

Outset and foremost, get vaccinated and boosted. The prove is clear that booster shots sharply increase antibiotic levels, which helps fend off infection and affliction.

Preventive health measures build upon one some other, and the same measures that helped protect against previous variants protect confronting Omicron. In addition to getting vaccinated, anybody should

article of clothing a well-fitting, high-quality mask
wash hands frequently
physically distance from others
improve indoor ventilation (open windows, etc.)
avoid crowded spaces.

What do I need to know almost the Delta variant?

The Delta variant is different from previous SARS-CoV-2 variants that take made their way to the US. It's highly contagious and may cause more than severe illness. It is too more likely than previous variants to be spread by vaccinated people experiencing quantum infections.

Evidence presented to the CDC showed the Delta variant to be much more contagious than previous variants, with a risk of manual like to chickenpox. Information technology also appears that people who are infected can spread the virus for longer periods of time.

In addition, people who are vaccinated and and then get infected (breakthrough infections) can as well spread the virus to others, perhaps to the same extent every bit those who are unvaccinated. However, people with breakthrough infections announced to be contagious for a shorter menstruation of time.

Finally, international studies point to the Delta variant being more than likely to cause severe disease.

The skilful news is that while vaccination may be less constructive at preventing infection and spread of the Delta variant, it is still highly protective against severe disease, hospitalization, and death. Become the COVID-19 vaccine if you take not already done then.

In July 2021, the CDC advised all people — vaccinated and unvaccinated — to wear masks in public indoor places, in areas of the country with substantial or loftier manual of the virus. Given the threat posed past the Delta variant, it'southward reasonable for everyone to start wearing a mask in indoor public spaces, regardless of the level of virus in your surface area.

Masks reduce the amount of virus nosotros breathe in, and breathe out. Combined with the vaccine, masks provide a one-2 punch that reduces the adventure of spread — to children who are not notwithstanding eligible for vaccines, to people with weakened immune systems, and to others who are unvaccinated. Masks also provide additional protection for the wearer, including who are fully vaccinated.

What exercise I demand to know virtually the AY.4.two (Delta Plus) variant?

Every bit viruses replicate, they may mutate, or slightly alter their genetic sequence. If a mutation is advantageous — making the virus more transmissible or able to sidestep allowed protection — it's more likely to survive and thrive. That'due south what happened with the Delta variant, which was many times more contagious than the original SARS-CoV-2 virus and speedily became the dominant variant effectually the earth. A new variant called AY.iv.2 (or Delta Plus), a descendent of the Delta variant, is at present gaining attending.

The AY.four.2 variant makes up about 11% of sequenced cases in the Great britain. It has as well been identified in a handful of U.s.a. states, just at present is responsible for less than 0.i% of COVID-19 cases in the US. The WHO has not classified AY.4.two as a variant of concern or a variant of involvement.

Preliminary testify from the United kingdom of great britain and northern ireland suggests that AY.four.ii is not more likely to atomic number 82 to hospitalization or cause astringent illness. And in a White House conference, the CDC director said in that location is no prove that this variant is less susceptible to current vaccines and treatments. It as well does not announced more than adept at evading immune protection.

Nonetheless, in that location is a lot we withal don't know about the AY.4.two variant, including whether and to what extent it is more transmissible than the original Delta variant. At this betoken, it appears to be only slightly more than contagious (10% to fifteen%). Its spread may as well exist influenced by human behaviors, such as whether people are masking indoors and the degree to which people in a community are vaccinated.

It seems very likely that we will be living with this virus, and its variants, for some hereafter. The best manner to minimize the emergence of new variants, and to protect ourselves from variants that already be, is to vaccinate as many people around the earth as possible. Why? Because the less the virus spreads, the less opportunity it has to replicate and mutate. For the aforementioned reason, information technology's vital to mask indoors, optimize ventilation, get tested if yous accept symptoms or are exposed to someone with COVID-19, and isolate if you test positive.

Which vaccines has the FDA approved and authorized for COVID-xix?

In August 2021, the FDA granted full approval to the mRNA COVID-19 vaccine developed past Pfizer and BioNTech. This vaccine had received emergency use authority (EUA) in December 2020. The mRNA COVID-nineteen vaccine developed past Moderna too received EUA in December 2020. The Johnson & Johnson adenovirus vaccine was granted EUA by the FDA in late Feb 2021; yet, in December 2021, the CDC stated a preference for vaccination with either of the mRNA vaccines.

The Pfizer/BioNTech vaccine has besides been authorized for children ages 5 to 17 years, though children ages v to eleven will receive a lower dose.

In improver, booster doses of all three vaccines have been authorized for eligible recipients.

Should I get a flu shot?

While the flu shot won't protect you from developing COVID-xix, information technology's withal a skilful idea. Most people older than six months can and should get the flu vaccine. Doing and so reduces the chances of getting seasonal flu. Even if the vaccine doesn't forestall you from getting the flu, it can decrease the gamble of severe symptoms. But over again, the influenza vaccine will not protect you confronting COVID-19.

Is it condom to employ steroids to control allergy and asthma symptoms during the COVID-19 pandemic?

Aye, it is safe to apply corticosteroid nasal sprays to control nasal allergies or inhaled corticosteroids to control asthma symptoms during the COVID-19 pandemic.

The American College of Allergy, Asthma and Immunology (ACAAI) issued a statement emphasizing the importance of controlling allergy and asthma symptoms during the pandemic. They said there is no show that intranasal or inhaled corticosteroids increase the risk of getting the COVID-nineteen infection or atomic number 82 to a worse effect if you do go infected.

The ACAAI statement was a response to concerns over reports warning confronting the apply of systemic steroids to treat hospitalized COVID-xix patients with specific respiratory complications. However, those reports did not refer to salubrious individuals using corticosteroid nasal sprays or inhalers to manage allergies or asthma.
