What Are Airborne Diseases?

Airborne diseases are infections caused by viruses, bacteria, or fungi that spread through microscopic droplets or aerosol particles in the air. These infectious particles can remain suspended in the air and infect people when inhaled. Common examples include influenza, measles, tuberculosis, COVID-19, chickenpox, and whooping cough.

Risk Factors for Airborne Diseases

Vaccines That Help Prevent Airborne Diseases

Vaccination remains one of the most effective ways to reduce the risk of airborne infections and their complications. Vaccines help the immune system recognize and fight harmful pathogens before serious illness develops.

MMR Vaccine (Measles, Mumps, and Rubella)

The MMR vaccine provides protection against measles, mumps, and rubella. It is a routine childhood vaccine and plays a vital role in preventing outbreaks.

Influenza (Flu) Vaccine

The seasonal flu vaccine helps protect against the most common influenza virus strains circulating each year and reduces the risk of severe illness.

Varicella (Chickenpox) Vaccine

The varicella vaccine helps prevent chickenpox and significantly lowers the chances of complications associated with the infection.

COVID-19 Vaccines

COVID-19 vaccines help reduce the risk of severe disease, hospitalization, and complications caused by SARS-CoV-2 infection.
