Public Health Policies that Prevent Communicable Diseases

Communicable diseases are illnesses caused by pathogenic organisms that can be spread directly or indirectly from one person to another. Vaccination, good hygiene, and proper food handling are some of the public health policies that help prevent communicable diseases.


Vaccines are one of the most successful public health interventions in eliminating communicable diseases. They cause the body to create immunity and prevent disease from occurring. Through herd immunity, they also protect individuals who are not vaccinated, including those who have weakened immune systems. Vaccines are available for a variety of diseases, and most countries have immunization requirements for children to help protect their health.

Good Hygiene

Good hygiene habits such as regular handwashing can help prevent the spread of many communicable diseases. Hands should be washed for 20 seconds with soap and clean running water after using the bathroom, before and after preparing food, after handling animals, and after coming in contact with someone who is sick.

Proper Food Handling

The spread of diseases through food and water contamination can be prevented through proper food handling techniques. This includes keeping kitchen surfaces clean and sanitized, washing hands before handling food, storing food correctly, and avoiding cross contamination between raw and cooked foods.


Public health policies can be effective in preventing communicable diseases. Vaccination, good hygiene, and proper food handling are all important measures that can help reduce the spread of these illnesses and improve public health.

By following these simple guidelines, everyone can do their part to keep themselves and their communities safe from infectious diseases.
