The WDH reported that they were collaborating with Banner Wyoming Medical Center in alerting people who might have been exposed to measles during such periods.
According to Dr. Alexia Harrist, who is the state health officer with the WDH, “We are asking individuals who were potentially exposed to self-monitor for measles symptoms for 21 days past the exposure date and consider avoiding crowded public places or high-risk settings such as daycare centers,” ABC News reported.
Wyoming became the 37th state to report a case of measles this year as the nation approaches a three-decade record of instances.
According to the data from the Centers for Disease Control and Prevention (CDC), as of Wednesday morning, there are already 1,227 confirmed cases.
The U.S. is now bound to surpass the 1,274 cases that were witnessed in 2019 and is likely to record the most cases since the year 1992.
Three deaths have been confirmed already in the current year; two of them in Texas involved unvaccinated children, and the other one in New Mexico was a case of an unvaccinated adult.
The CDC reports that among all the nationally confirmed cases, 95 percent of them are either not vaccinated or of unknown vaccination status.
According to Harrist, “Measles is one of the most contagious diseases we know, but it is preventable,” ABC News reported.
“The MMR vaccine is safe and highly effective, providing long-lasting protection. Two doses of MMR vaccine are about 97% effective in preventing measles, and we recommend that all Wyoming residents ensure they and their children are up to date on MMR vaccinations,” he added.
