Measles is a highly contagious virus transmitted through coughing and sneezing. According to the CDC, infected individuals can spread the virus for up to four days before becoming symptomatic. It typically takes 8 to 12 days after exposure for symptoms to develop, according to Columbus and Franklin County public health agencies.

The CDC recommends all children receive two doses of the MMR vaccine, with the first between 12 and 15 months old and the second at 4 through 6 years of age or at least 28 days after the first dose
