Wasn't measles eliminated in US?
Measles was officially eliminated from the United States in 2000, according to the CDC.
No measles were spreading in the U.S. and new cases were the result of people contracting the disease outside the U.S. and then returning.
MMR vaccinations have been dropping in Florida, US
"When more than 95% of people in a community are vaccinated, most people are protected through community immunity (herd immunity)," the CDC said.
"However, vaccination coverage among U.S. kindergartners has decreased from 95.2% during the 2019–2020 school year to 93.1% in the 2022–2023 school year, leaving approximately 250,000 kindergartners at risk each year over the last three years."
In Florida, during the 2022-2023 school year, the vaccination rate was 90.6%, the CDC reported.
What is measles?
Measles is a highly contagious virus that can be serious, especially for children under the age of 5, according to the CDC.
About 1 in 5 people in the U.S. who get measles will be hospitalized.
1 out of every 1,000 people with measles will develop brain swelling, which could lead to brain damage.
1 to 3 out of 1,000 people with measles will die.
How infectious is measles?
Measles spreads through the air when an infected person coughs or sneezes.
It is so contagious that if one person has it, up to nine out of 10 people around that person will become infected if they are not protected.
A person can get measles just by being in a room where a person with measles has been, even up to two hours after that person has left.
An infected person can spread measles to others even before knowing he/she has the disease — from four days before developing the measles rash through four days afterward, according to the CDC.
What are the symptoms of measles?
Seven to 14 days after being infected, the first symptoms appear, including:
high fever (may spike to more than 104°)
cough
runny nose
red, watery eyes
Three to five days after symptoms begin, a rash breaks out. It usually begins as flat red spots that appear on the face at the hairline and spread downward to the neck, trunk, arms, legs, and feet.
Small raised bumps may also appear on top of the flat red spots.
The spots may become joined together as they spread from the head to the rest of the body.
When the rash appears, a person’s fever may spike to more than 104°.
How can you protect yourself from measles?
The CDC said the best protection against measles is the measles-mumps-rubella vaccine. MMR vaccine provides long-lasting protection against all strains of measles.
Children need two doses of MMR vaccine for best protection:
The first dose at 12 through 15 months of age.
The second dose at 4 through 6 years of age.
