Four people have died from the hemorrhagic Ebola virus during a new outbreak in the Democratic Republic of Congo, officials said yesterday, warning that people are resisting measures to contain the highly contagious disease. The country has registered 6 Ebola cases. The virus has also resurfaced in Guinea, where it has already killed five people. A vaccination drive was launched last Monday, but as with past outbreaks, people in the region doubt the existence of Ebola and reject measures aimed at checking its spread. Ebola causes severe fever and, in the worst cases, unstoppable bleeding. It is transmitted through close contact with bodily fluids, and people who live with or care for patients are most at risk.
