What virus is commonly associated with the common cold?

The rhinovirus is the most commonly associated virus with the common cold. It is responsible for the majority of cold cases and is well-known for its ability to spread easily from person to person, particularly in crowded environments such as schools and offices. Rhinoviruses thrive in cooler temperatures, which explains their prevalence during the colder months when people are more likely to be indoors and in close contact with one another.

Additionally, rhinoviruses can cause symptoms such as a runny nose, sore throat, cough, and sneezing, which are hallmark signs of a cold. While other viruses, including coronaviruses and enteroviruses, can also cause respiratory symptoms, they are not as prevalent as rhinoviruses in the case of common colds. Influenza, while related to respiratory illnesses and often confused with a cold, causes a more severe illness known as the flu, which involves higher fever and systemic symptoms. Therefore, rhinovirus is the primary virus associated with the common cold due to its frequency and the nature of the symptoms it produces.
