Rhinovirus is a common virus that primarily causes the common cold. It is a member of the Picornaviridae family and is known for its ability to spread easily through respiratory droplets when an infected person coughs or sneezes. Symptoms typically include a runny nose, sore throat, and cough, and they usually resolve within a week or two. This virus thrives in cooler temperatures, making the upper respiratory tract an ideal environment for infection. While there is no specific treatment for a rhinovirus infection, over-the-counter medications can help alleviate symptoms. Good hygiene practices, such as handwashing, can reduce the risk of transmission.
