Ebola – still raising numbers

The Ebola outbreak in West Africa is going to get worse before it gets better, according to the top US public health official. The current outbreak is the deadliest since Ebola was discovered in 1976.

Tom Frieden, the director of the Centers for Disease Control, said the epidemic would need an “unprecedented” response to bring it under control. Health ministers from across West Africa are due to meet in Ghana to discuss the growing crisis. 

The World Health Organization says the outbreak has killed 1,427 people. The health body says it is the largest ever Ebola epidemic and has infected an estimated 2,615 people. Liberia has been hardest-hit of the affected countries, with 624 deaths and 1,082 cases since the start of the year.
