Final answer:
c) September to November In North America, RSV peak incidence typically occurs from January to March due to colder weather, with people being in close contact indoors leading to the spread of the virus.
Step-by-step explanation:
Respiratory Syncytial Virus (RSV) can cause a range of respiratory illnesses, from mild cold-like symptoms to severe pneumonia. While RSV can affect individuals year-round, there are specific peak times of the year when the virus is most prevalent. In North America, the peak incidence of RSV typically occurs in the fall and winter months, specifically from late fall to early spring. For the North American region, the months with the peak incidence of RSV are from January to March (option a), which corresponds with colder weather when people are more likely to be indoors and in close contact with each other, facilitating the spread of the virus.
The peak incidence of RSV (Respiratory Syncytial Virus) in North America occurs in the months of November to March. RSV is a common respiratory virus that causes mild cold-like symptoms but can also lead to severe pneumonia, especially in infants. During the winter months, RSV infections tend to increase, with the highest rates typically observed between December and February.
