<h3>What is measles?</h3>
A virus is the cause of the measles, which affects children. Measles is now almost always avoidable with a vaccine, despite once being extremely common. The measles, also known as rubeola, is contagious, dangerous, and occasionally fatal in young children. The measles still claims the lives of more than 200,000 people a year, largely children, despite the fact that death rates have been declining globally as more youngsters obtain the vaccine. Measles hasn't been a common disease in the United States in about 20 years due to high vaccination rates generally. The majority of recent cases of measles in the United States were brought in from abroad and affected people who were either unvaccinated or unaware of their vaccination status.
