Number of Ebola deaths are massively underestimated, warns WHO

August 2014 – AFRICA – The magnitude of West Africa’s Ebola outbreak has been underestimated, the World Health Organization (WHO) said, warning that unknown numbers of people were dying in “shadow zones” unrecorded by medical authorities. Official estimates place the number of known, suspected and probable cases of Ebola at nearly 2,500, just over half of which have been fatal. However, in a detailed assessment of the true extent of the crisis, the WHO described a bleak situation in which “invisible caseloads of patients… are not being detected by the surveillance system.” Recording of Ebola cases has been hindered for a number of reasons, particularly in Sierra Leone and Liberia, which have seen the worst of the epidemic, the WHO said in its latest situation report. Families are hiding infected loved ones, on the assumption that, because Ebola has no cure, it would be better for them to die at home rather than in hospital. However, effective treatment can improve chances of survival – a message that health authorities have been struggling to communicate to increasingly fearful populations. Isolation wards for Ebola patients are instead being viewed by many Africans as an “incubator for the disease”, the WHO said. Many medical facilities throughout the affected countries have closed, in many cases because medical staff have fled.

In the Liberian capital, Monrovia, where curfews aimed at slowing the spread of the virus have led to clashes between security forces and residents, hospitals and clinics have remained closed since authorities ordered them to be disinfected, and medical staff retrained to cope with Ebola three weeks ago. The WHO said that “virtually all health services have shut down” in the city, leading to a healthcare crisis beyond the impact of Ebola itself, with people forced to go without basic. Aphaluck Bhatiasevi, a WHO officer in Monrovia, said the re-opening of healthcare units was taking longer than expected, but that maternity services and obstetrics were now operating again at the city’s main hospital. “The system wasn’t at its best to begin with. We are facing challenges getting the healthcare facilities up and running,” she said. “Roads are not in a perfect condition. We are in the rainy season, and there are patients who do not have Ebola unable to get the necessary healthcare.” In remote villages, corpses are being buried before authorities are notified. In some cases, according to the WHO, epidemiologists reaching the villages have been forced to “count the number of fresh graves” as a crude indicator of Ebola deaths. –Independent
