Resumen de City living drives epidemic
Ebola virus continues its rampage in West Africa. There were 1,603 known cases as of last week, and there is no sign of the epidemic slowing. More than half of those infected have died. Ebola so far shows no sign of evolving into a global pandemic. The factor that could make this virus a bigger killer is social: urbanization, the same thing that unleashed HIV. Global concerns have focused on whether the virus could spread beyond the three chiefly affected countries--Guinea, Liberia and Sierra Leone. An infected traveler has spread the virus to three others in Nigeria, and as New Scientist went to press there were unconfirmed reports of potentially infected travelers in Morocco and Saudi Arabia. The World Health Organization is meeting this week to decide if the outbreak is an international public health emergency.
