Measles outbreak in US: cases highest in 35 years amid falling vaccination rates

The United States is experiencing a significant measles outbreak, with 2,318 confirmed cases reported this year by the US Centers for Disease Control and Prevention (CDC). This figure already exceeds last year's total of 2,289 cases and represents the highest number of infections recorded since the early 1990s.

Health officials attribute the resurgence of measles, a highly contagious disease, to a decline in vaccination rates. The CDC notes that herd immunity, crucial for preventing widespread outbreaks, requires at least a 95% vaccination coverage. Currently, the coverage for preschool-aged children has dropped to 92.5%. Alarmingly, 93% of this year's reported measles cases have occurred in unvaccinated individuals.

While 151 people have been hospitalized this year, no deaths have been reported. The Measles, Mumps, and Rubella (MMR) vaccine is highly effective, offering 97% protection after two doses. Public health efforts are focused on increasing vaccination rates to combat the spread of the virus, which causes fever, rash, and respiratory difficulties.
