Infectious Disease

Infections are caused by viruses, bacteria, mold and other organisms and lead to conditions like flu, chicken pox, pneumonia, sore throat, rashes, malaria and other ills. An infection occurs when these germs attack the body, causing it to respond with antibodies and white blood cells to defend itself. Preventing infectious disease involves eating a healthy diet, getting proper exercise to keep the body strong, and keeping clean by washing hands regularly.
