The U.S. is currently facing a measles outbreak, with 121 cases reported in 17 states so far this year. This concerning spike in infections has raised fears about the resurgence of a disease that was declared eliminated in the country 24 years ago.

The Centers for Disease Control and Prevention (CDC) has emphasized the importance of increasing public health efforts to boost routine vaccination coverage. Measles is a serious illness that can lead to severe complications, and the virus is highly contagious.

While people born before 1957 are generally considered immune to measles, those born after that date may need to consider their vaccination status. The CDC recommends one dose of the live measles vaccine for individuals born after 1957, with higher-risk individuals advised to consider two doses. If unsure about vaccination status, individuals are encouraged to get the measles, mumps, and rubella (MMR) vaccine.

Measles can result in hospitalization and severe complications, especially in adults. However, the MMR vaccine is highly effective, with two doses being about 97% effective at preventing measles if exposed to the virus. Fully vaccinated individuals who still contract measles are more likely to experience a milder illness.

Experts are puzzled as to why some fully vaccinated individuals may still get measles, but the severity of the illness is usually reduced. It is crucial for individuals to ensure they are up to date on their vaccinations to protect themselves and others from this potentially dangerous disease.
