There are different ways of controlling or limiting the spread of communicable diseases. These methods include isolation, quarantine, immunization, and vector control.

Isolation requires that a patient infected with a communicable disease be prevented from making contact with the general public. The Centers for Disease Control and Prevention has designated five categories of isolation: strict, protective, respiratory, enteric, and wound and skin.

Quarantine requires the separation of animals and humans that have been infected or exposed to a communicable disease from the general public.

Immunization is an effective means of controlling the spread of communicable diseases by the use of safe vaccines. A vaccine is a preparation of killed, attenuated, inactivated, or fully virulent organisms that are administered to induce or produce artificially acquired active immunity.

Vector control is a good way of controlling the spread of infectious disease when the vector, such as rodents or insects, is identified. This vector's habitats and breeding grounds can be treated with insecticides and poisons. Also, barriers such as window screens, netting, and repellents can provide protection against bites and infection.
