The WHO (World Health Organization) declared an international public health emergency due to the Ebola outbreak in Africa. On May 5, an outbreak of an unknown disease with high mortality was reported in Ituri province, in the Democratic Republic of the Congo (DRC).

At the same time, Uganda reported an imported case from the DRC, also caused by the Bundibugyo virus. So far, at least 88 deaths have been estimated. As there is currently no specific treatment or vaccine for this variant, international health authorities are implementing intensive measures to contain the outbreak.

To date, eight cases have been reported, three of them fatal. Five cases have been confirmed as hantavirus infections. The identified agent is the Andes virus, the only hantavirus species known to have limited person-to-person transmission, mainly in settings involving close and prolonged contact.

A deadly hantavirus outbreak aboard a cruise ship in the Atlantic Ocean has triggered an international public health response. The UN agency responsible for global public health says there is no need for panic or travel restrictions at this time.
