How does your immune system work?

  • Until a vaccine is available, our immune systems will need to adapt unaided to COVID-19.
  • The immune system is the body’s multi-level defence network against potentially harmful bacteria, viruses and other organisms.
  • A healthy lifestyle helps one’s immune system to be in the best shape possible to tackle pathogens, but it’s better to stop them entering the body in the first place.

The coronavirus pandemic has turned the world’s attention to the immune system, the body’s defence force against disease-causing bacteria, viruses and other organisms that we touch ingest and inhale every day.

But what is the immune system exactly, and how does it help repel intruders?

A force to be reckoned with

Think of it as the body’s personal army working from the cellular to macro level. Each cell, molecule, tissue and organ in this army plays a vital role in warding off invading pathogens, and also helps guard against internal threats like cancer.

The system has two types of response: innate and adaptive.

The body’s natural barriers against disease-causing intruders – for example, our skin, the mucous and hairs in our nose, and the acid in our stomachs – are part of our innate immune systems.

Adaptive immunity develops over a lifetime of contact with pathogens and vaccines, preparations which help our immune systems to distinguish friend from foe.

Vaccination safely teaches our adaptive immune systems to repel a wide range of diseases, and thus protect ourselves and others.

There is currently no vaccine for coronavirus, and we may not see one for 18 months or longer. So, for now, our immune systems must adapt unaided to this potentially deadly threat.

How to help your immune system

A healthy lifestyle – not smoking, drinking little or no alcohol, sleeping well, eating a balanced diet, taking regular moderate exercise and reducing stress – helps our immune systems to be in the best shape possible to tackle pathogens.

But the first line of defence is to prevent infection from entering the body.

The World Health Organization’s (WHO) recommended basic protective measures against COVID-19 are frequent handwashing with soap and water or cleaning hands with an alcohol-based rub; maintaining social distancing; avoiding touching your eyes, nose and mouth; and covering your nose and mouth with a bent elbow or tissue when you cough or sneeze.

These simple actions are vital to slowing the spread of a new disease like the coronavirus – to which nearly everyone is susceptible, but particularly older people and those with underlying health conditions.

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 respiratory tract (nose, throat, lungs), cause an asthma attack, and possibly lead to pneumonia and acute respiratory disease.

Treatment

There is currently no specific treatment for or vaccine to prevent COVID-19.  The best way to prevent illness is to avoid being exposed to this virus.

Prepare for COVID-19

  • Stock up on supplies.
  • Take everyday precautions to keep space between yourself and others.
  • When you go out in public, keep away from others who are sick.
  • Clean your hands often by washing with soap and water or using an alcohol-based hand sanitizer.
  • Avoid crowds and people who are sick.
  • Avoid cruise travel and non-essential air travel.
  • During a COVID-19 outbreak in your community, stay home as much as possible to further reduce your risk of being exposed.
  • If someone in your home is sick, have them stay away from the rest of the household to reduce the risk of spreading the virus in your home.
  • Avoid sharing personal household items such as cups and towels.

Follow your Asthma Action Plan

  • Keep your asthma under control.
  • Continue your current medications, including any inhalers with steroids in them (“steroids” is another word for corticosteroids).
  • Don’t stop any medications or change your asthma treatment plan without talking to your healthcare provider.
  • Discuss any concerns about your treatment with 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 too in case you need to stay home for a long time.
  • Know how to use your inhaler.
  • Avoid your asthma triggers.
  • 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. Take steps to help yourself cope with stress and anxiety.

Clean and disinfect things you or your family touch frequently

  • If possible, have someone who doesn’t have asthma do the cleaning and disinfecting. When they use cleaning and disinfecting products, have them:
    • Make sure that people with asthma are not in the room.
    • Minimize use of disinfectants that can cause an asthma attack.
    • Open windows or doors and use a fan that blows air outdoors.
    • Clean and disinfect surfaces like phones, remotes, tables, doorknobs, light switches, countertops, handles, desks, keyboards, toilets, faucets, and sinks daily.
    • Always follow the instructions on the product label.
    • Spray or pour spray products onto a cleaning cloth or paper towel instead of spraying the product directly onto the cleaning surface (if the product label allows).

How to Protect Yourself & Others

Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing serious complications from COVID-19 illness. More information on Are you at higher risk for serious illness?

  • There is currently no vaccine to prevent coronavirus disease 2019 (COVID-19).
  • The best way to prevent illness is to avoid being exposed to this virus.
  • The virus is thought to spread mainly from person-to-person.
    • Between people who are in close contact with one another (within about 6 feet).
    • Through respiratory droplets produced when an infected person coughs, sneezes or talks.
    • These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
    • Some recent studies have suggested that COVID-19 may be spread by people who are not showing symptoms.

Everyone should

Clean your hands often

  • Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.
  • If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.

Avoid close contact

  • Remember that some people without symptoms may be able to spread virus.

Cover your mouth and nose with a cloth face cover when around others

  • You could spread COVID-19 to others even if you do not feel sick.
  • Everyone should wear a cloth face cover when they have to go out in public, for example to the grocery store or to pick up other necessities.
    • Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.
  • The cloth face cover is meant to protect other people in case you are infected.
  • Do NOT use a facemask meant for a healthcare worker.
  • Continue to keep about 6 feet between yourself and others. The cloth face cover is not a substitute for social distancing.

Cover coughs and sneezes

  • If you are in a private setting and do not have on your cloth face covering, remember to always cover your mouth and nose with a tissue when you cough or sneeze or use the inside of your elbow.
  • Throw used tissues in the trash.
  • Immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not readily available, clean your hands with a hand sanitizer that contains at least 60% alcohol.

Clean and disinfect

  • Clean AND disinfect frequently touched surfaces daily. This includes tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.
  • If surfaces are dirty, clean them: Use detergent or soap and water prior to disinfection.
