What You Need To Know About Infectious Disease

Prevention & Treatment

Vaccines & Medicines

Medicines have existed in human society probably as long as sickness itself. However, with the advent of the modern pharmaceutical industry, biochemical approaches to preventing and treating disease have acquired a new level of prominence in the evolving relationship between microbes and their human hosts.

Vaccines

Vaccines

Many diseases that were once common—such as polio, measles, mumps, and tetanus—are now rare or well controlled because of vaccines.

We may not like getting vaccinated, but it has contributed greatly to our protection from harmful, if not deadly, diseases. Learn what vaccines are and how they work.

When you become ill with a bacterial or viral infection, your doctor commonly prescribes an antibiotic or antiviral medication. Find out more about the use of these medicines and what is challenging their effectiveness.

Infectious Disease Defined

Ecosystem

A functional unit that consists of all the living organisms in a particular area, as well as the nonliving, physical components in the environment—such as air, soil, water, and sunlight—with which the organisms interact, and how natural and human-made changes affect these interactions.
