At least six Americans exposed to Ebola during DR Congo outbreak

During a press conference on Sunday, the CDC declined to answer direct questions about the US citizens reportedly affected, adding that the risk to the US remained low.The US has also issued a Level Four travel advisory - its most severe level - warning against travel to the DR Congo.The WHO has said the outbreak in DR Congo's eastern Ituri province is a public health emergency of international concern, but did not meet the criteria of a pandemic.The agency has also warned it could potentially be "a much larger outbreak" than what is currently being detected and reported, with significant risk of local and regional spread.More than 28,600 people were infected by Ebola during the 2014-2016 outbreak in West Africa, the largest outbreak of the virus since its discovery in 1976.The disease spread to a number of countries within and outside of West Africa, including Guinea, Sierra Leone, the United States, the United Kingdom and Italy, killing 11,325 people. Jean Kaseya, director general of Africa Centres for Disease Control and Prevention, warned that in the absence of vaccines and effective medicines people should follow public health measures, including the guidance about handling the funerals of those who have died from the disease.
