December marks the start of peak respiratory syncytial virus (RSV) season, which typically lasts through February in most parts of the U.S.

RSV is a common virus that spreads primarily in the fall and winter. It can be transmitted through sneezes, coughs, or close contact such as a kiss. RSV can also spread by shaking hands or touching contaminated surfaces and then touching your face.

An illustration of symptoms and ways to prevent RSV

RSV symptoms

According to the Center for Disease Control (CDC), the symptoms of RSV often resemble those of the common cold, usually appearing four to six days after exposure and appear in stages rather than all at once. These symptoms include:

  • Wheezing
  • Runny nose
  • Congestion
  • Decrease in appetite
  • Coughing
  • Sneezing
  • Fever

Higher risk groups

For most people, RSV is not serious. However, certain groups are at a higher risk of severe illness, including:

  • Babies and young children.
  • Older adults, especially those 60+.
  • Adults with chronic medical conditions such as lung or heart disease, severe diabetes, or obesity.

Some children face additional risks, including:

  • American Indian and Alaska Native children.
  • Those born prematurely.
  • Children with chronic lung disease or congenital heart defects.
  • Those with severe cystic fibrosis or neuromuscular disorders.

RSV prevention and vaccination

Vaccines for RSV are now available, offering critical protection for those at higher risk. The CDC recommends:

  • Children aged 8 to 19 months at elevated risk should receive a single dose of nirsevimab.
  • Adults aged 60 to 74 at high risk and all adults aged 75+ should receive an RSV vaccine.
  • Pregnant women (32 to 36 weeks of gestation) should consider the bivalent RSVpreF maternal vaccine to protect their newborns.
  • Infants younger than 8 months should receive a single dose of nirsevimab, a monoclonal antibody.

There are several options to test for RSV, including at-home testing. The two most commonly used RSV lab tests are nucleic acid amplification tests (NAATs) and antigen tests

RSV hospitalizations and impact

RSV can lead to serious complications that lead to hospitalization. According to the CDC:

  • Between 58,000 and 80,000 children under age 5 are hospitalized annually due to RSV.
  • Among adults aged 60 and older, RSV causes 100,000 to 160,000 hospitalizations each year.
