2. Experts recommend that children obtain the measles, mumps and rubella — recognized as the MMR — vaccine in two doses: the
   first between 12 months and 15 months of age and a second between 4 and 6 years previous.

   One dose is about 93% effective at preventing measles if a person comes into contact with the virus.

   Two doses are about 97% efficient. Within the United States, more than 90%
   of youngsters have been vaccinated towards measles, mumps
   and rubella by age 2, in keeping with the US Centers for Disease Management and Prevention. Measles was declared eradicated in the
   United States in 2000, and since then, most circumstances within the US have emerged
   in communities with low charges of vaccination in opposition to the
   virus. Even when a illness is eradicated, outbreaks can nonetheless occur if an unvaccinated person travels to or from a country the place the disease continues to be common, becomes contaminated and
   brings it again to the United States, introducing the virus right into a
   community. That traveler can transmit measles to anyone who is unvaccinated.
   CDC says on its website. When the outbreak began, the CDC despatched a small
   group to Columbus to help with monitoring measles circumstances
   and pinpointing how the virus was spreading. Once a
   brand new case was recognized, well being officials labored rapidly to determine who had been in contact with that individual, whether the contacts had been vaccinated in opposition to measles and, if not, whether
   or not they’d been contaminated. Reducing rates of childhood immunization are a significant concern. About 90% of
   unvaccinated people who find themselves exposed to measles will become infected, based on Columbus Public Health, and about 1 in 5 folks within the US who get measles shall be hospitalized.
   She added that the outbreak took Columbus Public Health
   officials off-guard. There was not one single group or demographic of people inside central Ohio that was at an elevated threat of measles infections or had low vaccination rates.

   Moderately, small pockets of communities where families
   determined not to get their children vaccinated have been influenced by “false information that was distributed concerning the MMR vaccine being associated with autism,” Roberts stated,
   and that is what drove the outbreak. Measles can spread by way
   of the air when an contaminated individual coughs or sneezes or shares germs by touching objects or surfaces.
   Even after an contaminated individual leaves
   a room, measles virus can stay for up to
   2 hours within the air. Signs can embrace fever, cough,
   runny nostril, watery eyes and a rash of purple spots. In rare
   circumstances, it might lead to pneumonia, encephalitis or dying.
   Enroll here to get The results Are In with Dr. Sanjay Gupta each Tuesday from the
   CNN Well being staff. Making sure youngsters get the recommended MMR vaccinations as part of their routine childhood immunizations
   can assist reduce their risk of measles, stated Dr.
   Tanya Altmann, founding father of Calabasas Pediatrics in California and
   writer of “Baby & Toddler Basics,” who’s an adjunct clinical professor at Children’s Hospital Los Angeles.
