Two deaths reported
Health officials in Pennsylvania have reported two recent deaths from measles. They are the first US deaths from the disease in 2026, according to state authorities. The cases are still under investigation, and officials have not said whether the people who died were vaccinated or how they were exposed.
Measles is one of the most contagious diseases known. It spreads through the air when an infected person coughs or sneezes. The virus can survive in the air for up to two hours after an infected person leaves a room, which makes it easy for the disease to move through schools, clinics and crowded spaces.
Why measles is dangerous
Most people who catch measles recover, but the disease can be severe. Complications include pneumonia, brain swelling and deafness. Young children and people with weak immune systems face the highest risk. In rare cases, a slow brain infection can appear years after the original illness.
Before the vaccine was introduced, measles killed millions of children worldwide each year. The vaccine is highly effective and safe. Two doses protect about 97% of people for life, which is why public health agencies have pushed for high coverage in every community.
Vaccination rates are falling
Health experts say the deaths are a warning sign. Vaccination rates among US children have slipped in recent years, and several states now fall below the level needed for herd immunity. Some parents have delayed or skipped shots, and the result is more communities where measles can spread quickly.
When vaccination coverage drops, measles finds gaps. Outbreaks have already appeared in several states this year, and cases have been linked to travel from countries with active spread. Public health officials are urging families to check their vaccination records and catch up on missed doses.
The Pennsylvania deaths come as health agencies across the country watch measles numbers closely and prepare for the winter season, when respiratory viruses typically spread faster.
