With so little known about a deadly disease, one would think that with ebola on the rampage in three west Africa countries, air flights to and from these countries would be halted.
When riots or kidnappings present dangers in foreign lands, the State Department issues a travel advisory and warns, and sometimes prevents, Americans from traveling to areas of danger. As the ebola danger goes beyond the person himself, one would think public officials would have halted traffic to and from west Africa. In fact, it is harder for a critic of the US government, especially if the critic is Muslim, to enter the US than for a person infected with ebola. Indeed, there are a number of Russians who cannot enter the US because of unilaterally imposed US sanctions. But there are no sanctions against ebola.
Apparently, public health officials have an outdated and incorrect comprehension of ebola and how it spreads. A sufficient number of medical personnel protected against ebola patients' body fluids but without respirators have now been infected to indicate that the current strain of ebola can spread by air like flu. This also means surface contact.
