Lung problems, including asthma

COVID-19 targets the lungs, so you're more likely to develop severe symptoms if you already have lung problems, such as:

• Chronic obstructive pulmonary disease (COPD)
• Lung cancer
• Cystic fibrosis
• Pulmonary fibrosis
• Moderate to severe asthma

While some medications for these conditions can weaken your immune system, it's important to stay on your maintenance medications to keep symptoms as controlled as possible. You may want to talk to your doctor about obtaining an emergency supply of prescription medications, such as asthma inhalers.

It may also help to avoid the things that make your asthma worse. These asthma triggers can vary from person to person. Examples include pollen, dust mites, tobacco smoke and cold air. Strong emotions and stress can trigger asthma attacks in some people. Others are bothered by strong odors, so make sure the disinfectant you're using isn't an asthma trigger for you.

In addition to being an asthma trigger, smoking or vaping can harm your lungs and inhibit your immune system, which increases the risk of serious complications with COVID-19.
