Ebola is a frightening, unpredictable disease. Nearly 5,000 West Africans have died from the current outbreak with more than 13,000 people thought infected.

However, so far the problem remains largely limited to Liberia, Guinea and Sierra Leone. Two other countries, Nigeria and Senegal, have had cases, yet are now Ebola-free. The DR Congo had an outbreak of a different strain of Ebola that now looks like it might be contained. And while there has been one case of the disease in Mali, the patient died and no others have been confirmed at the time of writing -- though that may well change.

Despite clear geographical limits to the Ebola outbreak, many Americans seem confused. How else could you explain the recent Ebola scare that kept two children who had moved from Rwanda to New Jersey from attending school, despite the fact the East African country is Ebola-free (and further from West Africa than New Jersey is to Texas)? Or the resignation of a teacher in Kentucky due to a backlash to her traveling to Kenya? Or the significant cancellation of tourist trips to places like Kenya, Zimbabwe and South Africa?

These countries are nowhere near the West African countries where Ebola is actually a problem. Frustrated by this, Anthony England, a British chemist who earned a doctorate at Massachusetts Institute of Technology and has spent a significant amount of time in sub-Saharan Africa, decided to make a map to help explain what countries currently have Ebola cases and which don't. You can see the map above.

England has some relevant back story here as well: "I used to run scientific conferences in West Africa, to make leading scientific researchers, and problem solvers in general, in the West all the more aware of the pressing concerns of the developing world," he explains in an e-mail. While his company, Mangosteen, ultimately wound down almost 10 years ago, he now sees the Ebola outbreak as proof that the West needs to pay more attention to what happens in Africa.

"In the case of this Ebola outbreak, a problem which does not yet have a scientific solution and which started in a village in the developing world is actually visiting New York City and the West," he writes. "Eventually the rich world will realize that it makes no sense to leave one part of the world struggling in poverty with such terrible national infrastructures. Before it's done, this Ebola outbreak might teach them all that."

Ultimately, it was frustration that led England to make the map and share it on his Twitter account, which he uses to post information about Ebola. It has since spread around the Internet, with his initial post retweeted hundreds of times.

"Ignorance & misinformation is a big problem with Ebola. So a clueless Kentucky school causing the resignation of a teacher because she spent time in Kenya is just idiocy," he writes, "And that idiocy leads to fear which leads to people like Chris Christie implementing nonsensical anti-science quarantine restrictions. Ebola in the U.S. is becoming a farce."

Of course, there are some caveats to the map. England's decision to not include Mali or the DR Congo, despite the fact neither have been declared free of Ebola, has caused some thoughtful criticism. England writes that he understands the criticism, but his point still stands: "There are only 3 problem countries, and the world needs to know that," he explains.

It's a fair point. Africa is a vast, under-covered continent and Westerners often have trouble understanding its geography. Earlier this year, The Washington Post ran an online quiz that asked our readers to name African nations. The results were not heartening:

For added perspective, it's worth looking at a map first published in 2010 by cartographer Kai Krause. Keep it in mind when thinking of Ebola and Africa.
