LAGOS, Nigeria (AP) -- Nigerian authorities rushed to obtain isolation tents Wednesday in anticipation of more Ebola infections as they disclosed five more cases of the virus and a death in Africa's most populous nation, where officials were racing to keep the gruesome disease confined to a small group of patients.

The five new Nigerian cases were all in Lagos, a megacity of 21 million people in a country already beset with poor health care infrastructure and widespread corruption, and all five were reported to have had direct contact with one infected man.

Meanwhile, the World Health Organization began a meeting to decide whether the crisis, the worst recorded outbreak of its kind, amounts to an international public health emergency. At least 932 deaths in four countries have been blamed on the illness, with 1,711 reported cases.

In recent years, the WHO has declared an emergency only twice, for swine flu in 2009 and polio in May. The declaration would probably come with recommendations on travel and trade restrictions and wider Ebola screening. It also would be an acknowledgment that the situation is critical and could worsen without a fast global response.
