NOEL KING, HOST:
Measles is making a comeback in some parts of the world. The number of cases is rising at significant rates. The World Health Organization, in a new report, estimates there were nearly 10 million cases of measles last year - surprising because the disease is preventable with vaccines. NPR's Jason Beaubien has this story.
JASON BEAUBIEN, BYLINE: In Samoa, a measles outbreak has shut down that nation's schools indefinitely, and government offices have been closed for the last two days as part of a national immunization drive. In the Democratic Republic of Congo, measles has claimed more than 5,000 lives since January. This is twice as many people as have died in that country's ongoing Ebola outbreak. Globally, the WHO says 140,000 people died from measles last year, up from 90,000 in 2016.
KATE O'BRIEN: In 2018, there's been an increase in both the cases and the deaths that have occurred from measles. In other words, we're backsliding.
BEAUBIEN: That's Kate O'Brien, the WHO's top executive on immunization, speaking in a video statement accompanying the new report.
BRIEN: The reason we're having increases in cases and deaths of measles has to do, fundamentally, with people not getting vaccinated.
BEAUBIEN: There are various reasons for that. O'Brien denounces misinformation about vaccines that's gotten traction on some social media networks. In other places, the health systems are so poor that vaccines simply don't reach the kids who need them. To halt a measles outbreak in any given community, health officials say they need to get 95% of the population immunized against the virus. Xavier Crespin with UNICEF in the Democratic Republic of Congo says only 50% of Congolese kids have gotten their measles shots through routine childhood checkups. And then when measles does flare up, Crespin says armed conflicts in parts of Congo make those outbreaks extremely difficult to address.
XAVIER CRESPIN: Because of the security issue, we cannot go everywhere we need to go because there are some area - hot spots within the area, but it's very difficult for a local team to move toward this area and to vaccinate children.
BEAUBIEN: Most measles deaths are children under the age of 5. Measles is one of the most contagious human viruses in the world. It's one of the first diseases to make a comeback when health systems start to break down. Robert Linkins heads up Vaccine-Preventable Disease Surveillance at the Centers for Disease Control and Prevention. He says the current resurgence of measles reveals problems in basic health care delivery systems.
ROBERT LINKINS: Measles is the canary in the coal mine. It indicates that there are problems in a community with other vaccine-preventable disease coverage. And in many respects, it's a signal that we've got to pay more attention to where measles is occurring.
BEAUBIEN: And currently, that is all around the world. Jason Beaubien, NPR News.
