Respiratory Viruses

Many respiratory viruses, like influenza (flu), COVID-19, and respiratory syncytial virus (RSV), circulate year-round in the US and New York, typically with more activity in fall and winter (October - May).

Respiratory viruses can cause cold or flu-like symptoms and can be more serious in some people.

These illnesses can spread through:

  • Direct interactions like sneezing or coughing.
  • Indirect contact, like touching contaminated objects.

How Can I Protect Myself and Others?

To minimize the risk of catching or transmitting these illnesses:

  • Get Vaccinated: Visit the Vaccines and Immunization page to learn about seasonal flu, COVID-19, and RSV vaccines.
  • Stay home when sick and avoid close contact with people who are sick: This simple step can slow the spread of flu, RSV, COVID-19, and even the common cold.
  • Get tested: Displaying symptoms? Test kits for COVID-19 and the flu are widely available at pharmacies. If positive and you are in a higher risk group, call your health care provider to see if antiviral treatment is recommended for you.
  • Wear a mask: Wear a mask in crowded places. For best protection, opt for respirator masks like N95 or KN95. If you do not have those, use a surgical mask.
  • Wash your hands: Wash hands frequently for at least 20 seconds or use a 60% alcohol-based sanitizer.
  • Practice good hygiene: Cover coughs and sneezes with the inside of an elbow or tissue. Dispose of tissues properly and clean hands afterward. Clean frequently touched surfaces.
  • Improve air quality: Indoor air quality can play a key role in the transmission of airborne viruses. Good air flow helps stop viruses from building up and spreading. You can improve indoor air quality by:
    • Opening doors and windows
    • Using fans to bring in fresh air
    • Improving performance of mechanical ventilation (or HVAC) systems by performing regular maintenance, including cleaning or replacing air filters
    • Using portable air cleaning devices.

Who is at high risk?

Anyone can get a respiratory virus, but some people have a higher risk of getting very sick, including:

  • Older adults
  • Younger children
  • People with weakened immune systems
  • People with disabilities
  • People who are pregnant
  • People with underlying health conditions, such as heart disease, lung disease, obesity and overweight, liver disease, kidney disease, dementia, cystic fibrosis, cancer, blood disorders, HIV/AIDS, history of stroke, tuberculosis, and those who smoke or used to smoke.
