Every time an infected person coughs or sneezes, he or she spreads sickness. One sneeze alone can launch thousands of germ-jammed droplets nearly 20 feet (6 m), potentially infecting anyone in the blast radius. Bacteria and some viruses can survive for a short time on door handles, bathroom counters, and other surfaces.
There are several ways that germs can get into our bodies.
- They could be eaten in contaminated food.
- Germs in the air could be inhaled through our nose and mouth get into the lungs.
- Germs on our skin can enter via untreated cuts or wounds.
- They can be introduced to our bloodstream through injections, surgery or through animal or insect bites.
- Finally some specific germs in our body fluids can be passed onto others through bodily contact.
