Most sore throats are caused by viruses. The common cold is a viral infection that often starts with a sore throat and a general feeling of fatigue. Most people go on to experience mild fever, coughing, stuffy nose, body aches, and sneezing, with symptoms lasting one to two weeks.
The best treatment for a cold is rest and plenty of clear fluids. Gargling salt water can also help ease throat soreness.
