While people rely on doctors to stop the Ebola outbreaks in Sierra Leone, Guinea, and Liberia, doctors rely on suits to protect them._ by [Michael Scherer](https://time.com/author/michael-scherer/) ## Michael Scherer Aug 6, 2014 4:35 PM UTC  Medical staff working with Medecins sans Frontieres (MSF) prepare to bring food to patients kept in an isolation area at the MSF Ebola treatment centre in Kailahun, Sierra Leone on July 20, 2014. Medical staff working with Medecins sans Frontieres (MSF) prepare to bring food to patients kept in an isolation area at the MSF Ebola treatment centre in Kailahun, Sierra Leone on July 20, 2014. Reuters by [Michael Scherer](https://time.com/author/michael-scherer/) ## Michael Scherer Aug 6, 2014 4:35 PM UTC A computer program run by epidemiologists in Boston had already alerted key agencies of the U.S. government about West Africa’s Ebola outbreak four days before the World Health Organization first announced it, one of the doctors told TIME Tuesday. The computer’s advantage was its access to non-official online channels, in this case a [March 19 news report](http://www.standardmedia.co.ke/health/article/2000107329/mystery-hemorrhagic-fever-kills-23-in-guinea) in the Kenyan publication, the _Standard News_, which quoted a Guinean health official describing 23 recent deaths due to hemorrhagic fever in a region where bushmeat is regularly consumed. “These are new views on what is happening,” John Brownstein, an associate professor at Harvard Medical School and the founder of Healthmap.org, a group that scours social media and online news sources for early signs of disease outbreaks, told TIME. The rise in technology and global travel has created new hardships for the world’s infectious disease fighters. Pathogens can now travel around the world as fast as a airplane and global trade is booming. But there is a good-news corollary to this increased threat: The ability to detect diseases quickly has increased as well, by mining Internet usage, social media and news reporting for real-time signals of disease threats. Google search terms for words like flu and diarrhea can indicate spikes in infection, birthing the company’s Google Flu Trends project with the Centers for Disease Control and Prevention, which has demonstrated an ability to predict spikes in flu cases before official data. Health and flu-related Wikipedia article traffic has also [been shown to correlate](http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3990502/) with disease outbreaks as they happen. In cases where official data is not always reliable, social media can also provide better indications of emerging threats. During the 2013 outbreak of H7N9 bird flu in China, a health worker [forced hospital officials](http://healthmap.org/site/diseasedaily/article/power-social-media-updates-h7n9-outbreak-weibo-4313) to admit a recent death from the disease by posting the hospital chart of a recent patient on Weibo, the Chinese social media site. Weibo reports also signaled to the world that nurses had developed fevers after interacting with the patient. The new systems are by no means foolproof: U.S. social media has seen sharp spikes in discussions of ebola in recent weeks, for instance, but those do not indicate any evidence that the disease has jumped to the United States. “We tend to be very careful about the social media side of things,” Brownstein said. He also says there is still a significant human role in sorting through the digital news reports his group collects. But that hasn’t stopped most major U.S. government agencies from subscribing to Healthmap.org’s daily email alerts, and online postings. Brownstein said the Department of Defense, the World Health Organization, the Center for Disease Control and the Department of Homeland Security all subscribe to the monitoring efforts. Healthmap.org’s timeline of the geographic spread of Ebola, based on online news reports, can be found [here](http://www.healthmap.org/ebola/). ## Transcript [ MUSIC ] We touch our face about 1, 000 times a day. And these suits are about 115, 116 degrees you can, and you're losing three to five liters of sweat every time you go in, inside these suits. You can imagine. That you just want to rub your eyes or rub the sweat from your face, and you can't do that because that's an opportunity to come into contact with the virus. I was recently deployed on behalf of the World Health Organization to to Guinea to help with the Ebola outbreak. When you're providing care to patients, you're constantly being exposed to blood, vomit, diarrhea, every bodily fluid that's there. I'm sure you've seen pictures of the personal protection equipment or PPE that we're required to wear. We start with a base layer of scrubs, and then these thick rubber boots that come up to our knees. It's on top of the scrubs and the boots, we actually wear, an impermeable Tyvek suit, that, is incredibly hot. And then we also wear two pairs of gloves. On top of the tivex suit we have to put a hood, that is an impermeable hood that covers every other part of our, part of our head. We have to wear a respirator that covers our nose and our mouth, and then finally a pair of goggles that cover, cover our eyes on top of the hood. So basically, literally nothing is left uncovered. So that's just getting dressed. The PPE itself is, is a good first step. But even with all these protective equipments you're still handling needles. And you're still being exposed to, to patients' body fluids. We talk a lot about how how difficult the working conditions are. And how hot it and how restrictive these suits are but, I would say it comes nowhere near the difficult experience that it must be to be a patient. To be infected with it. Or to be the loved one of a patient who's going through that. And for me, that's something that I always think about. [ MUSIC ] That's the thing about this virus, it's actually... I hate to say the word easy, but it's really easy to control. I'm a firm believer that we can control this virus with just simple barrier precautions ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3086550/ebola-outbreak-africa-world-health-organization/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3086550/ebola-outbreak-africa-world-health-organization/"},"headline":"Meet the Bots That Knew Ebola Was Coming","datePublished":"2014-08-06T16:35:46.000Z","dateModified":"2026-08-04T08:00:56.512Z","description":"Online technology has improved the ability to detect and track outbreaks","url":"https://time.com/3086550/ebola-outbreak-africa-world-health-organization/","keywords":["Infectious Disease","World Health Organization","ebola"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdebc7bfc6100e55e/69869dc8169ab0297027a8a5/ebola-west-africa.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Michael Scherer","jobTitle":null,"url":"https://time.com/author/michael-scherer/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdebc7bfc6100e55e/69869dc8169ab0297027a8a5/ebola-west-africa.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Medical staff working with Medecins sans Frontieres (MSF) prepare to bring food to patients kept in an isolation area at the MSF Ebola treatment centre in Kailahun, Sierra Leone on July 20, 2014.","caption":"Medical staff working with Medecins sans Frontieres (MSF) prepare to bring food to patients kept in an isolation area at the MSF Ebola treatment centre in Kailahun, Sierra Leone on July 20, 2014.","creditText":"Reuters","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/infectious-disease/","name":"Infectious Disease"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3086550/ebola-outbreak-africa-world-health-organization/","name":"Meet the Bots That Knew Ebola Was Coming"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"How Suits Protect Doctors From Ebola","description":"While people rely on doctors to stop the Ebola outbreaks in Sierra Leone, Guinea, and Liberia, doctors rely on suits to protect them.","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/O5USUvDI/poster.jpg?width=720","uploadDate":"2014-08-04T22:03:18.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/O5USUvDI.m3u8","embedUrl":"https://time.com/3086550/ebola-outbreak-africa-world-health-organization/","duration":"PT2M12S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3086550/ebola-outbreak-africa-world-health-organization/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
