An outbreak of Ebola haemorrhagic fever that began in mid-March in Guinea has killed 86 people in the country, as of April 4. 143 suspected or confirmed cases have been reported in Guinea, and two people in Liberia tested positive for the infection. Suspected cases have also been reported in Sierra Leone and Mali. Alexander Bukreyev of the Galveston National Laboratory says: “[In the current outbreak], the initial infection of a human could result from consumption of bat's meat or from a contact with bat's excretions. Most likely the initial infection from bat triggered multiple cycles of human-to-human transmission of the virus.”
