BOSTON (AP) — The Ebola outbreak in West Africa is focusing a spotlight on an online tool run by experts in Boston that flagged a "mystery hemorrhagic fever" in forested areas of southeastern Guinea nine days before the World Health Organization formally announced the epidemic. 
  
 HealthMap uses algorithms to scour tens of thousands of social media sites, local news, government websites, infectious-disease physicians' social networks and other sources to detect and track disease outbreaks. Sophisticated software filters irrelevant data, classifies the relevant information, identifies diseases and maps their locations with the help of experts. 
  
 "It shows some of these informal sources are helping paint a picture of what's happening that's useful to these public health agencies," HealthMap co-founder John Brownstein said 
  
 HealthMap is operated by a group of 45 researchers, epidemiologists and software developers at Boston Children's Hospital. 
  
 The tool was introduced in 2006 with a core audience of public health specialists, but that changed as the system evolved and the public became increasingly hungry for information during the swine flu pandemic. 
  
 HealthMap generates information that includes locations of specific outbreaks and tracks new cases and deaths. The system is also capable of logging public sentiment. 
  
 The Ebola outbreak, the largest and longest ever recorded for the disease, has so far killed more than 950 people. It emerged in Guinea in March and has since spread to Sierra Leone, Liberia and Nigeria.

 The eight-year-old site, called healthmap.org, uses current feeds from social media, online news aggregators, and Twitter chats, along with official public health reports, to provide a comprehensive view of the current global state of infectious diseases.

 Traffic to the site has risen in recent days from those seeking information on the Ebola outbreak devastating West Africa, according to hospital spokeswoman Keri Stedman. 
  
 Users of the Healthmap site typically include local health departments, public health agencies, and international travelers to countries dealing with deadly infectious diseases. 
  
 “The news reports and social media posts aren’t always reliable, but in general they provide an up-to-date sense of what’s happening,” said John Brownstein, co-founder of HealthMap and director of the Boston Children’s Hospital Informatics Program. 
  
 Sometimes it takes days or weeks for the WHO to confirm illnesses or deaths. In fact, Healthmap had the first inkling of Ebola more than a week before any official announcement of an outbreak: On March 14, the site first picked up news reports about a “mystery hemorrhagic fever” that killed 8 in Guinea, but the WHO didn’t officially report on the Ebola outbreak until March 23. |||||

Those looking to keep track of the Ebola outbreak know it can take days for the World Health Organization to update cases, a source of frustration when it comes to the fast-spreading disease. Which is why an online tool created by Boston Children's Hospital is seeing a spike in visitors of late, reports the Boston Globe. It's an Ebola tracker—part of the HealthMap.org site—and it updates occurrences of the disease in real time by factoring in social media, news stories, government websites, doctors' online postings, etc., explains AP. "The news reports and social media posts aren’t always reliable, but in general they provide an up-to-date sense of what’s happening," says a co-founder of HealthMap, which made its debut in 2006. In fact, the site began getting reports of a "mystery hemorrhagic fever" in Guinea on March 14, nine days before WHO issued its first official report on the Ebola outbreak. (One of the two US patients undergoing treatment in Atlanta says he's getting better.)
