At this point in time, no.
This is different from Ebola, for example, where with Ebola there was a person-to-person transmission. With this particular disease it's transmitted through a vector and that is the virus. The vast majority, 80% of people who are infected, have no symptoms whatsoever. For most of the other 20% who are infected, there are very mild symptoms and a very small number are hospitalized with serious infections.
For the vast majority of people it's a very mild infection. We always recommend...for people who travel to countries with mosquitoes, because there are other diseases like malaria and dengue that are carried by the same sorts of mosquitoes, so that will continue. But we see no need for a travel ban, other than advising women who are pregnant that they should reconsider their travel until the outbreak has decreased.
