The video below shows how far your germs go when you cough. This demonstration will help you understand why you can pick up germs almost anywhere and why covering your mouth when you cough is so important.

The first two to four days of symptoms are when a cold is most contagious. According to the CDC, "People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses are spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.

Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children may pass the virus for longer than 7 days. Symptoms start 1 to 4 days after the virus enters the body. That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick." UGH!
