Is RSV More Common in the Winter or Colder Months?
RSV is most common during the Colder Months of the year, particularly during the fall, winter, and early spring. The virus is seasonal and tends to peak in the United States between November and March, with the highest incidence occurring in December and January. The colder weather encourages people to spend more time indoors in close quarters, which facilitates the spread of RSV. Additionally, the dry air during the winter months may affect the mucous membranes in the respiratory tract, making them more susceptible to viral infections. RSV thrives in cold, dry conditions, and during the winter months, it can be transmitted easily, especially in places like daycares, schools, and households with multiple children.
During these months, RSV infections can spread rapidly among young children, particularly those who have not yet developed a strong immune system or those with underlying health conditions. As a result, parents and caregivers need to be particularly vigilant during this time to minimize exposure. For babies, especially those under six months of age, RSV can be especially dangerous, leading to complications such as bronchiolitis and pneumonia.
By following good hygiene practices and minimizing exposure to crowded environments during the peak RSV season, parents can help reduce the risk of infection for their children.
