Frequently asked questions about measles

The resurgence of measles in the U. S. , including the Philadelphia area, underscores the importance of vaccination. Despite a 94. 5% vaccination rate among children by age six, health experts warn that this figure is below the 95% needed for herd immunity.

Measles is one of the most contagious viruses, and unvaccinated individuals face a 90% risk of contracting it after exposure. Severe complications can arise, including pneumonia and brain swelling, particularly impacting children and pregnant individuals. The health department promotes the MMR vaccine as the primary defense against the virus. As global measles activity rises, unvaccinated travelers increase the risk of outbreaks in the U. S.

Residents are encouraged to check their immunity and ensure vaccinations are up to date. Local health officials remain vigilant in monitoring and addressing potential cases.
