It takes from 7 to 10 days to fully recover from a cold virus but sometimes if the cold virus is more severe then it may take up to 14 days to fully recover after catching the cold virus.
To help yourself recover from a cold virus as quick as possible, get plenty of rest, take steamy showers, use a vaporizer or humidifier in your room and home and get plenty of Vitamin C.
Also take some over the counter cold medicine to help with the symptoms of the cold and stay home from work when you have a cold to prevent others from catching the cold or catching another strain of the cold virus yourself.
