Cold symptoms

Colds are caused by a virus and can occur year-round. The common cold generally involves a runny nose, nasal congestion, and sneezing. Other symptoms include sore throat, cough, and headache. A cold usually lasts about 7 days, with perhaps a few lingering symptoms such as a cough for another week.
