Understanding Measles Transmission and Vulnerable Populations
Measles is classified as a highly contagious viral illness that spreads primarily via airborne transmission through respiratory droplets. When an infected person coughs or sneezes, the virus remains suspended in the air or lands on surfaces, posing an infection risk to nearby susceptible individuals.

Health officials emphasize that certain groups face a significantly elevated risk of developing severe complications if they contract the virus. Infants, pregnant women, and immunosuppressed individuals are particularly vulnerable to these heightened health risks.
