“The problem with measles is that it is so contagious. It’s one of the most contagious diseases in existence,” says Yale Medicine infectious diseases specialist Dr. Scott Roberts. The U.S. experienced a spike in measles cases this year, with more than 1,000 confirmed cases in 30 states. The outbreak created alarm, particularly following a measles exposure at a Shakira concert in New Jersey, NBC News reported.
The measles virus is a powerful adversary, capable of a reproduction number (R0) of 12-18, that is, one carrier can infect 12-18 people. The virus is airborne and persists for as long as two hours in the air after the carrier departs, thus making it extremely contagious. AP News states that measles causes a high fever, cough, stuffy nose, and a rash that begins on the face and moves downward.
The MMR vaccine is your best protection. Two shots are 97% effective, and one shot provides 93% protection. The CDC suggests that kids get their first shot at 12-15 months and the second at 4-6 years old. Even with the recent outbreak, officials such as Dr. Paul Offit of the Children’s Hospital of Philadelphia, as cited by 6ABC, say most vaccinated adults do not need a booster.
However, if you’re unsure about your vaccination status, checking with your healthcare provider is wise. They can perform an antibody titer test to determine your immunity level. For those born before 1957, you’re likely immune, as measles was widespread before the vaccine’s introduction.
The recent surge in measles is also influenced by vaccine hesitancy and declined vaccination rates during the COVID-19 pandemic. In an overview by the WHO, over half the nations of the world are likely to experience large outbreaks. It is essential to have high vaccination rates to avoid subsequent outbreaks.
If you are going abroad or visiting large gatherings, check that your vaccinations are current. Infants 6-11 months old visiting high-risk destinations need to be administered with an early MMR vaccine dose, with the regular two doses after their first birthday.
If you’ve already been vaccinated, there’s generally no cause for concern. However, those who received the inactivated measles vaccine before 1968 may want to consult their doctor, as Dr. Gregory Poland of The Atria Research Institute notes that some of these early versions may not have provided lasting immunity. Staying informed and checking your vaccination status is a smart step toward protecting your long-term health.
As measles cases rise, staying informed and proactive about your health becomes increasingly important. The MMR vaccine continues to be a reliable and effective defense against this contagious virus. By ensuring that you and your loved ones are vaccinated, you not only safeguard your own well-being but also contribute to the greater goal of community protection and disease prevention.
