Brought on by decreasing vaccination rates in communities, measles is making an unwelcome comeback in the United States. The disease was considered "eliminated" in 2000, but following an outbreak in Texas earlier this year, the highly contagious disease has cropped up in 38 states.

"Researchers often think of measles as the proverbial canary in a coal mine," report Teddy Rosenbluth and Jonathan Corum of The New York Times. "It is often the first sign that other vaccine-preventable diseases, like pertussis [whooping cough] and Hib meningitis, might soon become more common."

For many adults and children, catching measles can be likened to having a cold accompanied by a very itchy rash. But for others, the disease can cause severe medical conditions, including "pneumonia, making it difficult for patients, especially children, to get oxygen into their lungs," the Times reports. "It may also lead to brain swelling, which can cause lasting damage, including blindness, deafness and intellectual disabilities."

The disease also decreases an individual's ability to fight off germs they had previously been immunized against. "Scientists call the effect 'immune amnesia.' During childhood, as colds, flu, stomach bugs and other illnesses come and go, the immune system forms something akin to a memory that it uses to attack those germs if they try to invade again," reports Denise Grady of The New York Times. "The measles virus erases that memory, leaving the patient prone to catching the diseases all over again."

Although the U.S. has dealt with "large measles outbreaks in the past, a confluence of factors has made it particularly difficult to rein in the virus this year," Rosenbluth and Corum report. "Nationally, the measles vaccination rate fell during the Covid-19 pandemic and has not rebounded to the 95% mark required to stem the spread of the virus in a community. . . . In Gaines County, the center of the Texas outbreak, just 82% of the population received the MMR [measles, mumps and rubella] vaccine that year."

Other countries are struggling with measles outbreaks as well. Rosenbluth and Corum explain, "Large outbreaks have spread through Mexico and parts of Canada, which has had a record number of cases this year. This spring, the World Health Organization announced that Europe had reported the highest number of measles cases in more than 25 years."
