Overview
Measles is a disease with very low incidence in the developed world. Lack of vaccination against measles is one of the biggest risk factors that predisposes measles spread. In developed countries like USA, most cases are attributed to unvaccinated or incompletely vaccinated travelers from other parts of the world. Primary vaccine failure occurs in approximately 5% of individuals vaccinated with a single dose of vaccine at 12 months of age or older and also predisposes an individual to the risk of developing measles.[1]
Common Risk Factors
- Unvaccinated individuals
- Living in crowded and/or unsanitary conditions such as prisons and college dorm rooms
- Traveling to less developed and developing countries where measles is common
- Weakened immune system even if vaccinated
- Winter and spring seasons
- Born after 1956 and never fully vaccinated since.
