Measles may be even more dangerous than doctors had thought. Researchers reported last week that the disease destroys immunity that the victim has developed to fight off other infections.
The researchers' findings help to explain why children often catch other infectious diseases after having measles. The findings also show the dangers of growing resistance to childhood vaccination in some countries.
Two recent studies showed for the first time how measles resets the body's natural defenses against disease.

Velislava Petrova is with Cambridge University in England and the Wellcome Sanger Institute, a not-for-profit research center. She also was a co-leader of one of the measles studies.
This ... is a direct demonstration in humans of ‘immunological amnesia', where the immune system forgets how to respond to infections encountered before, she said.
Geneticist and researcher Stephen Elledge was a co-leader of the second study. He said the results showed really strong evidence that the measles virus is actually destroying the immune system.
Elledge is with the Howard Hughes Medical Institute in the United States.
The findings are important for public health efforts worldwide. A decrease in vaccination rates is leading to measles outbreaks in some areas. The spread of measles can lead to a return of other dangerous diseases, such as influenza, diphtheria and tuberculosis.
Two injections of a vaccine can prevent measles. The treatment is safe and effective, and has been in use since the 1960s.
But World Health Organization, or WHO, experts warned last month of an alarming upsurge of cases among unvaccinated people all over the world.
In the first three months of this year, the number of cases jumped 300 percent from the same period in 2018, WHO reports show.
