Respiratory illness are infections that affect the respiratory tract (nose, throat, airway, and lungs). These illnesses are most common in the fall and winter. Respiratory illnesses are caused either by viruses, including COVID-19, Influenza (Flu), Respiratory Syncytial Virus (RSV), or colds, or bacteria, such as pneumonia. Check out our Respiratory Illness Fact Sheet for more information.
Some respiratory illness, such as colds, have relatively mild symptoms and will usually get better without treatment. However, other illnesses, like COVID-19, RSV and Flu can make people very sick and may need hospitalization. Severe symptoms are more common in young children, the elderly, and those with compromised immune systems or other health conditions.

Spread of Respiratory Illnesses
Respiratory illnesses are spread through the air and direct or indirect contact.
- When someone with a respiratory illness coughs or sneezes, the infection can travel through the air (usually within six feet) and be breathed in.
- Through direct contact (i.e., kissing, holding hands, etc.) with someone who is sick.
- Through indirect contact, by touching a contaminated surface or object (i.e., doorhandles, rails, etc.) and then touching your mouth, nose, or eyes.
Preventing the Spread of Respiratory Illnesses
You can reduce the spread of infections using the layers of protection below. Taking these steps will help lower the risk of you or those around you becoming sick.
- Stay up to date on your COVID-19 vaccines and flu shots.
