ABOUT MEASLES
Measles is a highly contagious respiratory virus that spreads through the air when an infected person breathes, speaks, coughs or sneezes. The virus can linger in the air for up to two hours and can infect up to 90% of unprotected close contacts. Complications can include pneumonia, brain inflammation and death
Nationwide, measles cases have been rising since early 2025. Nearly 2,300 cases were reported last year, with most occurring among unvaccinated children
Symptoms typically begin seven to 21 days after exposure and include cough, runny nose and conjunctivitis accompanied by a high fever. A rash usually follows, starting on the head or neck and spreading downward. People are contagious from four days before the rash appears until four days after
HA advises health care providers to report suspected cases immediately and consider post-exposure treatment for exposed patients. The measles, mumps and rubella vaccine can be given within 72 hours of exposure. Immunoglobulin may be administered within six days
For most people 6 months and older who are eligible for vaccination, receiving the MMR vaccine within 72 hours of exposure is recommended
