The common cold is an amazingly democratic infection. It will infect even the healthiest and most fit of people– even those with the strongest immune system. The entry point of the virus is through the nose and once it gets there, 95% of all persons will get a cold.
There are three main ways that the cold virus can get into the body.
1) Touching skin or other surfaces that may be infected then touching your eyes or nose.
2) Inhaling droplets from someone’s sneeze or cough.
3) inhaling smaller droplets from coughs and sneezes that hang in the air for longer periods of time.
Conclusion: wash your hands often and stay away from people with colds.
