Sex in a time of Ebola

But since Ebola victims can infect others only when they are showing symptoms — high fever, vomiting, diarrhea, weakness and aches — physical intimacy probably isn’t a common way of transmitting the disease. However, the Ebola virus can survive in semen for months after a man recovers from the infection, posing an ongoing threat to sexual partners long after he is well. At a time when a man’s bloodstream is swimming with antibodies, and he is immune to the disease, he still may be able to infect others. As a result, Ebola survivors in West Africa and elsewhere are being advised to remain celibate or use condoms for three months after their release from treatment centers. In Lofa County, Liberia, where the epidemic began six months ago, UNICEF workers doing outreach work were told the story of one local man who recovered and infected his girlfriend through sex, according to a UNICEF official. The woman later died. (We couldn’t independently verify that account). The World Health Organization made a point of this on Monday when it noted that “in a convalescent male, the virus can persist in semen for at least 70 days; one study suggests persistence for more than 90 days.” The Ebola outbreak in West Africa has reached the United States, as officials confirm one case in Dallas. Here’s how U.S. health officials plan to stop the virus. (Gillian Brockell and Jorge Ribas/The Washington Post) The magnitude of the threat is not entirely clear, however. After past Ebola outbreaks, follow-up studies of people who have recovered from Ebola found no evidence that the virus was transmitted from a recovered patient to close contacts, according to Bruce Ribner, medical director of Emory University’s Infectious Disease Unit, who led the team that successfully treated American missionaries Kent Brantly and Nancy Writebol. Some body fluids and excretions clearly transmit the virus: Blood, vomit and feces are being blamed for the rapid spread of the hemorrhagic disease in Liberia, Sierra Leone and Guinea, where more than 3,400 people have died from Ebola infection. The Ebola virus also has been detected in urine and breast milk, according to the WHO. Other fluids are trickier. Ebola is not an airborne virus, like SARS or the flu, but “theoretically,” the WHO notes, “wet and bigger droplets from a heavily infected individual, who has respiratory symptoms caused by other conditions or who vomits violently, could transmit the virus – over a short distance – to another nearby person. As the Ebola crisis continues in West Africa, the CDC is training doctors, nurses and other health care workers going to Ebola treatment units in West Africa. (AP) “This could happen when virus-laden heavy droplets are directly propelled, by coughing or sneezing (which does not mean airborne transmission) onto the mucus membranes or skin with cuts or abrasions of another person.” But the agency adds that there are no studies that document this method of transmission. Saliva and tears may also carry the virus, but studies blaming them for transmission had small samples and were inconclusive. “In studies of saliva, the virus was found most frequently in patients at a severe stage of illness,” the WHO said. “The whole live virus has never been isolated from sweat,” the agency added, but one infectious disease specialist we spoke with said it stands to reason that Ebola could be transmitted by direct contact with someone else’s perspiration. *Source Washington Post]]>
