Update – July 25, 2021

We updated this blog post to include updated information and guidance from the Asthma and Allergy Foundation of America (AAFA) and the Centers for Disease Control and Prevention (CDC).

Note: Because this is a constantly changing situation, any data in this blog post may not represent the most up-to-date information. We will update this blog when possible.

In December 2019, a new coronavirus named SARS-CoV-2 started spreading and triggered a pandemic (worldwide outbreak). This coronavirus causes an illness known as COVID-19.

The coronavirus spreads through close contact from person to person. A person with the virus can spread it to others by talking, coughing, sneezing, singing, or breathing. The virus will be in large or small droplets that are exhaled from the mouth or nose out into the air.

If you are within 6 feet (2 meters) of someone who is ill with COVID-19, you may be at greatest risk for becoming infected. But it may be possible to catch the virus even if you are more than 6 feet away from an infected person because very small droplets can spread in the air. If someone who is sick coughs on or near your face, you may get infected. People may be infected with the coronavirus and not show any symptoms. They may spread the virus without knowing it. The virus may also spread through direct contact with a person who has COVID-19.

What Are the Symptoms of COVID-19?

According to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), COVID-19 symptoms can include:

  • Fever
  • Chills
  • Cough
  • Shortness of breath or trouble breathing
  • Feeling tired and weak
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Stuffy or runny nose
  • Nausea or vomiting
  • Diarrhea

If you or someone you know has these emergency warning signs, call 911 or go to the emergency room immediately:

  • Trouble breathing or shortness of breath
  • Pain or pressure in the chest that doesn’t go away
  • Newly confused
  • Can’t wake up or stay awake
  • Cyanosis which is tissue color changes on mucus membranes (like tongue, lips, and around the eyes) and fingertips or nail beds – the color appears grayish or whitish on darker skin tones and bluish on lighter skin tones

According to the CDC, this list may not include all symptoms. If you have any symptoms that are severe or concerning, call your doctor.

The CDC warns that symptoms may appear two to 14 days after coming in contact with the virus.

How Can I Tell the Difference Between Asthma, COVID-19, the Flu, a Cold, or Seasonal Allergies?

Some symptoms are similar between these respiratory illnesses. Respiratory illnesses may worsen asthma, so it’s important to keep taking your asthma medicines. If you have a fever and a cough, call your doctor. If you have seasonal allergies, there are things you can do to treat them at home. If your allergy symptoms are hard to control, make an appointment with an allergist.

This chart can help you figure out if you may be feeling symptoms of asthma, allergies, or a respiratory illness like COVID-19, the flu, or a cold:

Are People With Asthma at Risk of Severe Illness From COVID-19?

Many studies show that having asthma does not put you at a greater risk of getting COVID-19 or having severe COVID-19.1,2,3 A study published in “The Journal of Allergy and Clinical Immunology: In Practice” (JACI: In Practice) found that people with well-controlled asthma have less severe COVID-19 outcomes than people with uncontrolled asthma.4

The CDC continues to list moderate-to-severe asthma as a chronic lung disease that can make you more likely to have severe illness from COVID-19.

No matter what, it is important to keep your asthma well-controlled. If your asthma is not under control, you are at a greater risk in general of having an asthma episode or attack, going to the emergency room, staying in the hospital, or even death. If you feel like your asthma is not well-controlled, talk with your doctor as soon as possible.

Even though people with asthma are not at the highest risk for COVID-19, it is still important to keep your asthma under control. Common medicines you may take for asthma and allergies do not increase your risk of getting COVID-19. They will help you keep your asthma under control. You are at greater risk for having an asthma attack if you stop taking your medicines. Take your medicines at the first sign of symptoms as listed on your asthma action plan. Continue to take these medicines as prescribed:

  • Quick-relief medicine (such as albuterol)
  • Inhaled corticosteroids (controller medicines)
  • Oral corticosteroids (such as prednisone)
  • Biologics
  • Antihistamines (allergy medicine)
  • Proton pump inhibitors for acid reflux
  • Nasal allergy sprays
  • Allergy shots

If you have any questions about asthma medicines and COVID-19, talk with your doctor.

If you need to take quick-relief medicine (such as albuterol) for an asthma episode, use an inhaler (with a spacer if directed by your doctor) if possible. Using a nebulizer can increase the risk of sending virus particles in the air if you are sick. But if you have a nebulizer and solution, it is OK to use it to treat an asthma episode. When using a nebulizer, limit the number of people in the room or use it in a room by yourself.

How Can I Avoid Getting COVID-19 (And Other Respiratory Infections)?

The following steps will help you avoid COVID-19, the flu, and other respiratory infections:

1. Get your vaccines.

Vaccines can help protect you, your loved ones, older adults near you, teachers, and essential workers from getting a respiratory infection. They can also cut down your symptom severity if you do get sick. Vaccines reduce the burden on our health care system by reducing the number of people who get COVID-19 or the flu.

Everyone who is 6 months and older can get a COVID-19 vaccine for free with no out-of-pocket costs in the United States. There are currently four vaccines available: Pfizer, Moderna, Johnson & Johnson (J&J), and Novavax.

Visit to find out where you can get the COVID-19 vaccine near you. Most people can get the COVID-19 vaccine with no issues. Allergic and adverse reactions are rare.

The flu vaccine is recommended for everyone age 6 months and older with rare exceptions.

It is safe to get both the COVID-19 vaccine and the flu vaccine at the same time.

2. Wear a mask.

Face masks can help reduce the spread of the coronavirus. They can benefit people who are vaccinated and unvaccinated alike. Some people may have COVID-19 and not show symptoms for a few days, while some may not have any symptoms at all. And some vaccinated people have gotten breakthrough infections, which have usually been mild.

Wear a mask that fits snugly on your face, and covers your nose, mouth, and beard completely. Wear a mask when you leave your home, if you are caring for someone at home who is sick, and if you have been exposed to someone with COVID-19. People with asthma should be able to wear face masks.

Face masks offer other benefits as well. They can reduce your exposure to pollen, air pollution, and other respiratory infections like the flu.

3. Keep a physical distance from people outside your household.

In general, the more closely you interact with other people and the longer that interaction, the higher the risk of coronavirus or flu spread. Try to stay home when possible when these illnesses are spreading in your community. Avoid large crowds of people, especially in indoor locations. When in public, keep at least 6 feet apart. Stay away from people who are sick or have been in contact with someone who is sick. Even when you’re at home with family, don’t share makeup, food, dishes, or eating utensils.

Postpone any unnecessary travel during the COVID-19 pandemic. See the CDC’s guidelines on how to protect yourself at specific locations and in certain situations, such as shops, public places, gatherings, and more.

4. Wash your hands properly and often.

Use soap and warm water to wash your hands for 20 to 30 seconds. Always wash your hands before and after eating and after coughing or sneezing. Don’t touch your eyes, nose, or mouth.

If you don’t have access to running water, use an alcohol-based hand sanitizer that is at least 60% ethyl alcohol (ethanol) or 70% isopropyl alcohol (isopropanol).

5. Make sure your indoor spaces are well-ventilated and have good indoor air quality.

If you are staying indoors more because of COVID-19, be mindful of the quality of your indoor air. The air inside our homes can often be more polluted than the air outside. Unhealthy indoor air can be full of asthma triggers and allergens that can cause symptoms and make your asthma harder to control. Take steps to improve and maintain healthy indoor air quality.

Air circulation is important too. Keep your indoor spaces well-ventilated by opening windows or doors, using fans, running air cleaners, or using proper air filters in your HVAC system.

Current evidence shows the risk of the coronavirus spreading is much lower outdoors than indoors. Good ventilation in your indoor environment may help reduce the spread of the coronavirus. It may also affect the risk of transmission (how fast it spreads).

On days when pollen is low and air quality is good, open your windows to let in fresh air. Run your HVAC system as much as possible (especially when windows are closed). Use high efficiency air filters in your HVAC system and replace them at least every three months.

6. Take care of your health.

Take your asthma control medicines as directed to keep your airways open. Eat well and get enough sleep.

Pollen (such as grass or ragweed pollen) may impact people across the U.S. too. Seasonal allergies can affect people with allergic asthma. If pollen allergies trigger asthma symptoms for you, be sure to follow your allergy treatment plan to keep your allergies under control to prevent asthma episodes or attacks.

If you stopped seeing your allergist or getting allergy shots (immunotherapy) during the COVID-19 pandemic, consider making an appointment soon. Keeping up with your regular allergist visits is an important part of keeping your asthma controlled.

The most important thing you can do is to keep your asthma under control. If your asthma is not under control, call your doctor right away.

In general, tracking your symptoms and following your asthma action plan are key to managing your asthma. Some people use peak flow meters to monitor their airways. Monitoring your blood oxygen levels with a pulse oximeter (or “pulse ox”) is not a recommended part of home management of asthma. Many pulse oximeters you can buy for home use are not as accurate as medical grade devices.

It is important to remember that the symptoms you feel should always come before pulse ox and peak flow numbers. But if your peak flow numbers are down and you don’t have symptoms, follow your asthma action plan and contact your doctor.

There are no data demonstrating that monitoring your pulse ox through an oximeter or smartphone app will help manage your asthma. As always, talk with your doctor about the best ways to monitor your symptoms and asthma control.6

If I Think I Have COVID-19, What Should I Do?

If you start having symptoms of COVID-19, get tested or take an at-home test. If you have mild symptoms and are not at high risk for having more severe COVID-19, you do not need to call your doctor. Call your local health department within 24 hours to let them know so they accurately report local cases.

If you are at high risk for severe COVID-19, call your doctor within 24 hours if you test positive. They may want to you to take the medicine Paxlovid.

Many pharmacies have various testing options (including at-home or drive-thru tests). The United States Postal Services is providing free at-home COVID-19 tests. U.S. households can get eight rapid antigen COVID-19 tests for free. To receive them, you’ll need to complete an online form. Please note: You will not need to enter any credit or debit card details to place the order.

Some doctors may offer telehealth (video or virtual appointments). If that is an option, ask your insurance company if telehealth is covered under your plan. And if you have Medicare, you might be able to have a virtual visit with your doctor. The government expanded the coverage of telehealth services during the COVID-19 pandemic.

Stay home and isolate from family members so you don’t spread the coronavirus to other people.

My doctor recommended using an N95 mask with a cooling feature. I don't know how hard these are to get since most need to go to medical professionals, but we just happened to have some from a purchase for another purpose 10 months ago. They make breathing MUCH easier.


Hello, I have asthma. Should asthma people wear masks? I have to go back to school soon and we all have to wear masks. Masks bother me, because it makes it hard to breath and starts to make me have an attack. I hope, I don’t have to even thought it is a lot of exposure. Thanks


@Wolfbane I am so sorry to hear you have COVID-19, but thank goodness you are not as ill as you could be. 

How are you feeling after 2 weeks, do you think you've turned the corner? 

Sending healing vibes your way!



I have COVID-19 and asthma. I also have other health conditions and am over 65. I am not as ill as I expected (going on two weeks with it). I have to wonder of those of us on corticosteroids have some protection from the inflammation that is so deadly with COVID-19. I have to be on prednisone for adrenal insufficiency as well as well, so it's a bit different for me, but with the mortality rate for asthmatics with COVID-19 being below what would be expected, it gives me pause about this link.


People suffering from severe to moderate asthma are considered at high risk of getting infected from the coronavirus. The virus affects your respiratory tract, and most probably, it can trigger an asthma attack. There is also a possibility that the situation gets more critical and led to pneumonia and acute respiratory disease. Pharmaceutical companies are still working on the COVID19 mediation, and it will take a few months to be available in the market. So, the best way to avoid getting exposed to coronavirus is to stay at home, eat healthy food, maintain social distancing, and take your asthma medication on time. Ventolin inhaler helps to cope up with an asthma attack and easily available online to purchase from


Anthony Constantinou says, “We need to keep our preventer inhaler daily as prescribed. This will be helpful to cut risk of an asthma attack being triggered by coronavirus or any respiratory virus.”


Hi i am from Europe. And i have asthma for many years. I am very scared now because COVID19. I follow all instructions. I haven't been out of the apartment already 2 months. I live with my parents who are retired. Only my father went out for food once a week and always wore a mask. I have had a low temperature 37.2 for 14 days. It changes during the day. In the morning I don't have and in the evening increases to 37.2 when I fall asleep it is normal. I don't have other symptoms. What is happening to me?


It seems from the information that I've read about COVID-19, the virus is highly unpredictable; symptoms and outcomes vary widely, depending on the strength of each individual's immune system, comorbidities, and age. Physicians and researchers are still uncovering many details of how the virus affects different patient populations, and they learn new information every day. They report that some with underlying conditions survive the virus, while many others die, which is why health experts have advised everyone, especially those with underlying conditions at any age, to take all precautions. As far as comparing COVID-19 to car accidents, it was interesting to read that statistics show approximately 40,000 people in the U.S. die in car accidents each year. As of today, it has been reported that more than twice that amount, over 80,000 people in the U.S., have died of COVID-19, within months. Surprisingly, we have a much greater chance of dying from COVID-19 than from perishing in a car accident. Stats also show that the current COVID-19 death rate in the U.S. has reached 6%, and an individual state's percentage is as high as 8%: Stay safe out there. 


Hi @Islandgirl - that's a great question and we did ask our medical experts about allergy shots:

Should I Continue to Get Allergy Shots During the COVID-19 Pandemic?

With spring pollen on the rise in the U.S., regular allergy shots are an effective way to help you manage your allergy and allergic asthma symptoms. Check with your allergist's office to find out what changes they have made to how they are giving allergy shots. Continue with your allergy shot schedule unless your allergist tells you differently, practicing proper social distancing.

Hi @savail -  AAFA has reached out to the CDC to share concerns and questions about masks and face coverings. We will update our community as new information develops.

During pregnancy, wimen can see their asthma symptoms get better, worse or stay the same. It's sounds like yours may have gotten worse. Have you checked bin with your doctor about your increased issues? They can best guide you to a treatment plan that will keep you and the baby safe and healthy.

Kathy P

Hi Islandgirl, welcome to the AAFA forums! That is a great question, have you consulted with your dr about your concern?

You can also submit your question to our "Ask The Allergist". 

Savail, you are correct, there is conflicting information on wearing masks. This is the latest recommendation from the CDC for people with asthma. Have you ever seen an allergist or pulmonologist?

I keep finding conflicting recommendations from places online about whether or not those with asthma or other breathing issues should wear a face covering. Normally, my asthma is mostly just set off by mold or the heat (or both, because mold is a real **** when it gets hot and humid outside), but since becoming pregnant, it's just been all around bad and hard to breathe in general. I try to minimize the amount I use my inhaler, but all of the disinfectants in use haven't been helping any, either. I've tried to wear a face covering, but even without being up and moving around, I end up struggling to breathe. For example, just sitting on the couch working at sewing one had me out of breath once! I may talk on the phone one day to my mother for an hour and be fine, but another day end up out-of-breath and using my inhaler for the same activity, without any clear trigger.

I don't actually have any idea about spirometry levels or preventative meds or anything of the sort because I never actually had proper asthma testing done despite lifelong breathing problems (something about nasal passages and sinuses and narrowed something-or-other that leaves me prone to recurring respiratory infections and the occasional semiannual bout with bronchitis and/or pneumonia, so it never crossed our minds to have me tested because we assumed all of the problems were due to just that). Instead, I was given a rescue inhaler and diagnosis by a doctor a few years ago because my O2 sat dropped low enough one night at work to where my charge nurse had to give me an emergency breathing treatment with stock supplies, and I was forbidden to go back to work until I'd seen someone about it. Since I had confirmed improvement of O2 sats with the nebulizer, I was given a rescue inhaler and the asthma tag, and it definitely helps bring me back to my baseline for breathing when I use it, but my baseline is already poor to begin with.

But I digress! The CDC mentions that people with breathing problems shouldn't wear face coverings, but what do they consider to be breathing problems? Does asthma count? Does it not count? Does it only count if you legitimately can't breathe in a mask? How do you demonstrate this if your city/county starts requiring face coverings--carry a face covering, put it on and wait to go blue in the face so they tell you nevermind? Do I tell them I have asthma? Do I tell them "hi, my breathing passages are a piece of crap, and I have impaired breathing when my face is covered but no actual diagnosis other than asthma?" I jest, but seriously, what should I be doing?

Albuterol inhalers, nebulizers and other asthma treatments may significantly strengthen the lungs and help symptoms of Coronavirus and fight off the infection faster. Even people without asthma could use asthma treatments to fight corona virus.

You are going to get people killed! Do not use a nebulizer. The only time you should use it is if you have asthma and you live alone. 1. It does not "fight it off" 2. A nebulizer makes the virus into an aerosol that now has extraordinarily bigger infecton radius. If you are not a pulmonologist do not give advice you will hurt people

actually they do give nebulizers to other people besides those who have asthma , people with COPD and Bronchitis often get them too. And you do not need to live alone to use one. he is not getting people killed. you are grossly over reacting. sometimes if people do not use one they will die of either a COPD flare or an asthma attack. You can use one at home as stated from a professional above as long as you are in your own space in the house alone or where there is a huge space that is well ventilated but preferably alone at this time. wow 

The use of nebulizers (specifically nebulizers) can increase the risk of infection of those around you if you are ill, because of aerosolization. Depending on who's around you, infection can be deadly. Continue to follow your normal asthma routine as doctors recommend, but if you fall ill and you use a nebulizer, make sure you know the risk to those around you and prepare yourselves accordingly. Many hospitals have stopped using nebulizers in COVID-19 patients for this reason. It may help you, but it might make another person sick. Thank you for coming to my Ted Talk.

okay just a question but how do you all figure that people with asthma do not get shortness of breath? I know tons of people with it ,including myself and we all get shortness of breath! this is not a correct statement to say people with asthma seasonal allergies etc do not get short of breath , because we in fact do. honestly the symptoms of Covid-19 are so vague it is scary for people with lung issues because we have those symptoms often except for fever, and for me with lupus etc (and other diseases) I get a fever sometimes , at least once a week and I cough all the timefrom COPD and asthma , this chart is not very helpful for someone like me.


i’m 16 years old working as a cashier. I have mild asthma which is well controlled and have never been in icu or anything serious. there’s about 1,200 cases in my province and i live in the main city area. should i continue to go to work? they have put up plexiglass and provided masks and gloves but i feel it is not enough. i’ve only worked around 400 hours so i don’t qualify for EI and i don’t want to lose my job. i’m not sure if i qualify to take a leave of absence for 6 months and i’m not sure what to do. i also take public transit to work but it is not too crowded. i feel the customers don’t respect my space enough and come too close/go around the plexiglass. my parents are encouraging me to not go anymore. what are my options?? please help!
