Nigeria contains Ebola – and US officials want to know more

US teams are headed to Nigeria to learn about its success in using 'contact tracing'  – a significant practical step that limited the spread of the virus.

A Nigerian health official waits to screen passengers for Ebola at an airport in Lagos, Nigeria, in August. Last week, the Center for Disease Control proclaimed that Nigeria had stopped its outbreak.

When Ebola reached Nigeria, health officials were worried about the populous country's ability to control the virus – particularly in Lagos, the nation’s coastal megacity and transport hub. 

But this week, teams of American health officials are Lagos-bound to learn from Nigeria's experience in defying expectations and stopping the outbreak before it could wreak havoc.

Since July 20, the day Nigeria’s so-called “Patient Zero” arrived in Lagos, officials have recorded a total of only 19 cases, with no new cases since Aug. 31. Last week, on the same day the US confirmed its first case of Ebola, the Center for Disease Control (CDC) proclaimed that Nigeria had stopped its outbreak. 

Meanwhile, Sierra Leone, one of three West African countries hard hit by Ebola, recorded 81 new cases in the past 24 hours. 

"[B]ecause of a rapid public health response, effectively tracking nearly 900 contacts, it appears they have] been able to stop the outbreak in Nigeria,” CDC Director Tom Frieden said Sunday. “Though we can't give the all clear yet, it does look like the outbreak is over there. I'm confident that wherever we apply the fundamental principles of infection control in public health, we can stop Ebola."

Nigeria’s success appears to be rooted in "contact tracing" – determining every single person that Patrick Sawyer, or Patient Zero, had contact with, and then monitoring them for signs of the virus.

 “Contact tracing can stop the Ebola outbreak in its tracks,” a chart distributed by the CDC declares

Now contact tracers are at work in the US, setting out to track down as many as 100 people who may have been exposed to Thomas Duncan, who traveled from Liberia to Dallas, where he was eventually diagnosed with the virus, The New York Times reports. 

It is an immense task. The Washington Post outlines how it went in Nigeria:

From that single patient came a list of 281 people, [Gavin MacGregor-Skinner, who helped with the Ebola response in Nigeria] said. Every one of those individuals had to provide health authorities twice-a-day updates about their well-being, often through methods like text-messaging. Anyone who didn't feel well or failed to respond was checked on, either through a neighborhood network or health workers.

...In the end, contact tracers — trained professionals and volunteers — conducted 18,500 face-to-face visits to assess potential symptoms, according to the CDC, and the list of contacts throughout the country grew to 894. Two months later, Nigeria ended up with a total of 20 confirmed or probable cases and eight deaths.

Ethiopia, one of two countries recognized by the World Health Organization as prepared for a possible Ebola outbreak, also has a vigorous tracing process that applies to every visitor from West Africa.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
