How worried should people be about the measles? An expert explains

Measles cases are on the rise in the United States, with 45 infections reported in 17 states as of March 7. This is close to the total number of cases recorded in the country in the entirety of 2023. The World Health Organization has noted that the global increase in measles infections and death is due to a decline in vaccination coverage. Measles is highly contagious and spreads through droplets from the nose, mouth, or throat of infected individuals. Symptoms include fever, fatigue, cough, and a rash. Measles can lead to severe complications and even death, particularly in unvaccinated individuals. The measles, mumps, and rubella (MMR) vaccine is highly effective at preventing measles, with two doses having a 97% efficacy rate. The CDC recommends that all children receive two doses of the MMR vaccine, and older children and adults who haven’t been vaccinated should also consider it. During measles outbreaks, additional guidance for vaccination may be issued. It is crucial to maintain a high vaccination rate to prevent the further spread of measles.
