People with Moderate to Severe Asthma

This information is based on what we currently know about the spread and severity of coronavirus disease 2019 (COVID-19).

Risk of Severe Illness from COVID-19

People with moderate to severe asthma may be at higher risk of getting very sick from COVID-19.  COVID-19 can affect your nose, throat, lungs (respiratory tract); cause an asthma attack; and possibly lead to pneumonia and acute respiratory disease.


There is currently no preventive treatment or vaccine for COVID-19.  The best way to prevent illness is to avoid being exposed to the virus (SARS-CoV-2) that causes COVID-19.

Prepare for COVID-19

Protect Your Health This Flu Season

Getting a flu vaccine during 2020-2021 is more important than ever because of the ongoing COVID-19 pandemic. Flu vaccination is especially important for people who are at high risk from flu; many of whom are also at high risk for COVID-19 or serious outcomes.

Follow your Asthma Action Plan

  • Keep your asthma under control by following your asthma action plan.
  • Avoid your asthma triggers.
  • Continue current medications, including any inhalers with steroids in them (“steroids” is another word for corticosteroids). Know how to use your inhaler.
  • Do not stop any medications or change your asthma treatment plan without talking to your healthcare provider.
  • Talk to your healthcare provider, insurer, and pharmacist about creating an emergency supply of prescription medications, such as asthma inhalers. Make sure that you have 30 days of non-prescription medications and supplies on hand in case you need to stay home for a long time.
  • Take steps to help yourself cope with stress and anxiety.
  • As more cases of COVID-19 are discovered and our communities take action to combat the spread of disease, it is natural for some people to feel concerned or stressed. Strong emotions can trigger an asthma attack.
  • For information on administering asthma medication in schools, visit K-12 Schools and Child Care Programs.

Any disinfectant can trigger an asthma attack.

Follow the recommendations below to reduce your chance of an asthma attack while disinfecting to prevent COVID-19.

  • If you have asthma,
    • Ask an adult without asthma to clean and disinfect surfaces and objects for you.
    • Stay in another room when cleaners or disinfectants are being used and right after their use.
    • Use only cleaning products you must use. Some surfaces and objects that are seldom touched may need to be cleaned only with soap and water.
    •  Make a list of the urgent care or health facilities near you that provide nebulizer/asthma treatments. Keep it close to your phone
    • If you have an asthma attack, move away from the trigger such as the disinfectant or the area that was disinfected. Follow your Asthma Action Plan. Call 911 for medical emergencies.
  • The person cleaning and disinfecting should:
    • Follow recommendations for cleaning and disinfecting to prevent COVID-19.
    • Choose disinfectants that are less likely to cause an asthma attack, using EPA’s list of approved productsexternal icon such as:
      • products with hydrogen peroxide (no stronger than 3%) or ethanol (ethyl alcohol)
      • products that do NOT contain peroxyacetic acid or peracetic acid.
    • Limit use of chemicals that can trigger asthma attacks, such as bleach (sodium hypochlorite) or quaternary ammonium compounds (e.g. benzalkonium chloride), and do not use them in enclosed spaces.
    • Follow additional precautions for cleaning and disinfecting places where people with asthma may be, to reduce exposure to asthma triggers.
  • Use products safely and correctly:
    • Always read and follow the directions on the product label to ensure you are using it safely and effectively.
    • Wear skin protection such as gloves and consider eye protection to protect yourself against splashes.
    • Make sure there is enough air flow (ventilation).
    • Use only the amount recommended on the label.
    • Use water at room temperature for dilution (unless stated otherwise on the label).
    • Do NOT mix chemical products. Label diluted cleaning solutions.
  • Store products safely and correctly
