The U.S. Centers for Disease Control and Prevention on Friday issued a health alert advisory to notify clinics and public health officials to be watchful after a case of measles was confirmed at a large gathering in Kentucky.
On Feb. 24, the Kentucky Department for Public Health identified a confirmed case of measles in an unvaccinated individual with a history of recent international travel, the CDC said.
While infected, the individual attended a large religious gathering on Feb. 17–18, with an estimated 20,000 people there from other states and countries, the national agency said.
Measles is one of the most contagious human viruses and is almost entirely preventable through vaccination. However, it requires 95% vaccine coverage to prevent outbreaks among populations.
The CDC said doctors should consider measles as a diagnosis with anyone with clinically compatible symptoms. The agency also asked physicians to recommend measles, mumps and rubella shots for patients who are unvaccinated or not fully vaccinated.
