Guinea has declared a public health emergency over an Ebola epidemic that has killed more than 1,000 people in three West African states and is sending health workers to all affected border points, Reuters quoted a government official as saying. An estimated 377 people have died in Guinea since the world's worst outbreak of Ebola began in March in remote parts of a border region next to Sierra Leone and Liberia. Guinea says its outbreak is under control with the numbers of new cases falling, but that the new measures are needed to prevent further infection from the other countries at the centre of the epidemic. Sierra Leone has declared Ebola a national emergency as has Liberia, which is hoping that two of its doctors diagnosed with Ebola can start treatment on Thursday with some of the limited supply of experimental drug ZMapp. Nigeria, which has also declared a national emergency, on Thursday said it had 11 cases of Ebola after a doctor who treated a Liberian man who brought the disease to Lagos fell ill.
