The Congolese health minister has announced the opening of three treatment centers in eastern Congo as the Ebola outbreak continues. The World Health Organization declared the outbreak a public health emergency of international concern on Sunday. Over 300 suspected cases and 88 deaths have been reported. Cases have also appeared in the Congolese capital, Kinshasa, and in the city of Goma. The outbreak is caused by the Bundibugyo virus, a rare Ebola variant with no approved treatments. Congo accounts for most cases, but two have been reported in Uganda. Health authorities are assessing the need for increased measures but caution against overreactions.
