The Centers for Disease Control and Prevention reported Tuesday that 107 people from 21 states, including states bordering Virginia, have reported contracting the measles.
Two of the cases were reported in children under the age of one in New Haven county.
The CDC's 2018 midyear measles report appears high in comparison with recent years.
Symptoms include a mild-to-moderate fever, a cough, runny nose, red eyes and a sore throat.
In 2014, there was a record number of cases, with 667 cases from 27 states, which marked the largest outbreak since the elimination of measles in the USA was documented in 2000, the CDC stated.
In 2017, 118 people were reported to have measles nationwide. The CDC didn't say how many of those cases were in Kansas. "Measles is so contagious that if one person has it, 90% of the people close to that person who are not immune will also become infected".More news: Qatar pledges to invest $15 billion into Turkey
Measles is a vaccine-preventable respiratory infection that can result in hospitalization, pneumonia, encephalitis and death.
The measles vaccine - known as the MMR or measles, mumps and rubella vaccine - is very effective.
Dr. Michael McKenna with St. Vincent Medical Group urged all parents to get their child vaccinated. One dose is about 93% effective at preventing the contagious disease if you come into contact with the virus.
He was not surprised though to hear about a measles outbreak because they are seeing rising rates of people not vaccinating their child.
The CDC says measles are still common in many parts of the world including some countries in Europe, Asia, the Pacific, and Africa, so travelers with measles can bring it into the U.S.
