Infectious diseases are caused by germs—tiny living organisms found in the air, soil and water. While many germs are harmless, others can cause life-threatening illnesses. Under certain circumstances, people can become infected by touching, eating, drinking or breathing something that contains germs. Germs are also spread through insect and animal bites, kissing and sexual contact. Vaccines, proper hand washing and medicines can help prevent infectious diseases.
