The Centers for Disease Control and Prevention reports that it is keeping tabs on measles cases in multiple states around the country.
According to the CDC, from January through July of this year 107 people from 21 states and the District of Columbia were reported to have measles.
Florida was one of those states where measles has been reported.
In 2014, the United States experienced a modern record number of measles cases, with 667 cases from 27 states reported to the CDC.
Health officials say it does not appear that the U.S. is anywhere near approaching the number of cases reported in 2014, but prudence and care are recommended given the current circumstances.
According to the CDC, the symptoms of measles generally appear about seven to 14 days after a person is infected, and typically begin with high fever, cough, runny nose, and red, watery eyes.
Three to five days after symptoms begin, a rash breaks out.
When the rash appears, a person’s fever may spike to more than 104° Fahrenheit.
After a few days, the fever subsides and the rash fades.
The CDC says measles is a highly contagious virus that can spread to others through coughing and sneezing.
Also, measles virus can live for up to two hours in an airspace where the infected person coughed or sneezed.
If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected.
Officials warn that measles is so contagious that if one person has it, 90 percent of the people close to that person who are not immune will also become infected.
