From Dr. Michael T. Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, in today's print edition of the New York Times:
"There are two possible future chapters to this story that should keep us up at night.
The first possibility is that the Ebola virus spreads from West Africa to megacities in other regions of the developing world. . . .
The second possibility is one that virologists are loath to discuss openly but are definitely considering in private: that an Ebola virus could mutate to become transmissible through the air. . . .
In 2012, a team of Canadian researchers proved that Ebola Zaire, the same virus that is causing the West Africa outbreak, could be transmitted by the respiratory route from pigs to monkeys, both of whose lungs are very similar to those of humans. Richard Preston’s 1994 best seller “The Hot Zone” chronicled a 1989 outbreak of a different strain, Ebola Reston virus, among monkeys at a quarantine station near Washington. The virus was transmitted through breathing, and the outbreak ended only when all the monkeys were euthanized. We must consider that such transmissions could happen between humans, if the virus mutates."
