Cold is a common infection of the nose and throat. This primarily affects the nose. Coughing, sore throat, runny nose, sneezing, and fever are apparent symptoms of cold. It usually lasts to seven to ten days. However, some symptoms of cold lasts up to three weeks. Over 200 virus strains are the reason behind cold in which ‘rhinoviruses’ are the most common. Common cold mostly affects the nose than throat, and sinuses and sometimes affects both eyes as well via conjunctivitis. The basic reason behind cold is the resistant response to the infection instead of tissue destruction by the viruses themselves.
