This is Scientific American's 60-Second Science. I am Karen Hopkin. This'll just take a minute. 

As you probably know, viruses can jump from animals to people, we've gotten flu from birds and pigs, and HIV, the virus that causes AIDS, is thought to have come from chimps¹. But swapping² bugs⁴ is a two-way street, because scientists from Virginia Tech have found that African chimps were coming down with human viruses. The researchers have been studying chimps in Mahale Mountain National Park in Tanzania. And they found that the apes are suffering from a respiratory illness that’s caused by a virus, very similar to the one that causes bronchitis and pneumonia⁵ in people. The results will appear in the August issue of American Journal of Primatology. How and where the chimps caught this bug³ is a mystery, but it is possible they got it from scientists or tourists who frequent the park. The husband and wife research team and their 4-year-old daughter have been living and working in the park for the past year in a state-of-the-art, eco-friendly field Laboratory. There they hope to develop ways to monitor and protect the health of these endangered apes. Of course, the best way to protect the chimps might be to remind visitors to sneeze into their sleeves and avoid being too simpatico with the simians.

Thanks for the minute for Scientific American's 60-Second Science. I am Karen Hopkin.
