Measles cases in the United States have climbed to its highest level in 25 years, with almost 700 cases reported across the country this year already. 22 states have reported measles cases in 2019 in what experts have called the worst year for measles since 1994. Measles is a highly infectious disease, easily spread through airborne means such as coughing or sneezing by infected people. A big reason for the uptick in cases is misinformation about vaccinations and legal exemptions made through religious liberty laws. There is no link between vaccines and autism, despite claims made online by some individuals.
