Infectious diseases like measles and chicken pox can be prevented by taking vaccines at the right time. Taking good care of the hygiene and sanitation can also keep you away from a number of viral and bacterial infections. Mild infections can be treated by antibiotics. But in viral infections, antibiotics may not work. Antibiotics do not work on viral infections because these viruses hide inside cells, thus making it difficult for the antibiotics to attack them.

Vaccination has successfully reduced diseases like polio, measles and chickenpox. Vaccines can also prevent flu, hepatitis A, hepatitis B, and other infectious diseases.
