It is not clear how many Centres for Disease Control and Prevention workers are now forced to tackle the outbreak from DRC's capital, Kinshasa, almost 1 600km away.
New statements in two top medical journals this week are calling on the U.S.to change its mind and send its experts back where they are sorely needed.
In the Journal of the American Medical Association, one group noted that the USA government weeks ago ordered all Centers for Disease Control and Prevention personnel - "some of the world's most experienced outbreak experts" - from Congo's outbreak zone because of security concerns.
Previously, the ReEBOV Antigen Rapid Test Kit was eligible for procurement to Ebola-affected countries, under the WHO Emergency Assessment.
Despite its conclusion, the committee emphasized in a statement that the Congolese government, World Health Organization and partners "must intensify the current response" to the ongoing outbreak and that this "should be supported by the entire global community", or "the situation is likely to deteriorate significantly". The CDC supports the expertise of the State Department and Department of Defense "in determining locations where it is safe to position our staff". If malaria is reduced, health workers will be able to focus on real Ebola patients and keep others away from the wards. Teams with the WHO and Congo's health ministry venture out on virus containment missions accompanied by United Nations peacekeepers or other armed security in areas where gunfire echoes daily.
Last month, the WHO heeded the recommendation of an expert advisory committee to not declare the Democratic Republic of the Congo's latest Ebola epidemic a public health emergency of worldwide concern - a proclamation that would have mobilized more resources and garnered global attention. The trial is the first-ever multi drug trial for treatment of Ebola.
