医学考博每日一读：Measles deaths said to drop
LONDON (AP) — The number of measles deaths worldwide has apparently dropped by about three-quarters over a decade, according to a new study by the World Health Organization and others.
Most of the deaths were in India and Africa, where not enough children are being immunized.
Health officials estimate that about 9.6 million children were saved from dying of measles from 2000 to 2010 after big vaccination campaigns were rolled out more than a decade ago. Researchers guessed that the number of deaths fell during that time period to about 139,300 from 535,300, or about 74 percent.
But scientists had solid data for only 65 countries. For the 128 others surveyed, they used modeling to come up with their estimates.

He noted that the global 85 percent vaccination coverage rate was the highest recorded.
The study was paid for by the Centers for Disease Control and Prevention and was published Tuesday in the journal The Lancet.
Measles is one of the most infectious diseases and affects mostly children. It causes a fever, cough and a rash. The disease kills about one to two children for every 1,000 it infects and can also cause pregnant women to have a miscarriage.
In recent years, it has surged in Europe — the number of people infected since 2007 has tripled. Doctors say cases are rebounding there because people do not realize how serious measles is and are skeptical of the vaccine.
Last year was the worst year for measles in the United States in 15 years, with 222 cases — mostly imported by visitors or residents infected overseas.
