The US Centers for Disease Control and Prevention continues to record rising levels of hospitalizations associated with Covid-19 as well as increasing hospitalizations for influenza and the respiratory syncytial virus, also known as RSV.
For a regular cold, symptoms tend to peak within the first few days after they start. However, some symptoms, especially a runny or stuffy nose or cough, can last up to 14 days, according to the CDC.
It's not unusual for some specific symptoms to linger even after others resolve.
