Dr. Siddhartha Mukerhjee is advocating for the development of a pilot program to begin testing those who may be carrying Ebola (for example those travelers arriving in the US or UK from West Africa). Dr. Mukherjee argues (correctly, I think) that three containment strategies currently being discussed are insufficient: travel bans, quarantine, and temperature screenings in airport. These policies will either cast too broad a net and/or fail to identify plausible cases. Dr. Mukherjee suggests PCR testing - that amplifies viral DNA found in a teaspoon of blood and can identify virus before someone is symptomatic. The downsides: the test is pricey, between $60-$200, takes a few hours, and there is currently no infrastructure to conduct these in ports of entry or exit. I agree that current measures against Ebola seem ineffective, but I'm not sure if this will be the answer ...
