decSpanish health officials were investigating Wednesday whether a nursing assistant infected with Ebola got the deadly disease by touching her face with Ebola-tainted protective gloves, while a strike by Ebola burial teams in Sierra Leone left abandoned bodies in the streets of the capital. More than 3,400 people have been killed by the Ebola outbreak in West Africa, which has hit Sierra Leone, Guinea and Liberia hardest. The case of Spanish nursing assistant Teresa Romero has shown that health workers can contact Ebola even in highly sophisticated medical centers in Europe. In Madrid, Dr. German Ramirez of the Carlos III hospital said Romero remembers she once touched her face with the gloves after leaving the quarantine room where an Ebola victim was being treated. Health officials say Romero twice entered the room of Spanish missionary Manuel Garcia Viejo, who died of Ebola on Sept. 25 — once to change his diaper and again after he died to retrieve unspecified items. Ramirez said Romero believes she touched her face with the glove after her first entry. More
