ProMED-mail has a useful aggregation of recent news reports on Ebola. But the moderator's comments point to a longstanding problem in public health:
Although the majority of victims of EVD have been women, due to their exposure to the virus as caregivers for the sick in the home and washers of the bodies of their dead relatives, they are reported to be the most defiant of health workers' attempts to hospitalize EVD patients, often far from their home village, and to restrict moving their dead across borders and their performance of traditional burial practices.
Therefore, I suppose that among the many secret societies in Sierra Leone, the one referred to is the women's Bondo Secret Society. For a detailed explanation about it by a local author in August 2013, see: http://www.sierraexpressmedia.com/archives/59854. It includes the following passage:
"The Minister of Social Welfare Gender and Children's Affairs, Moijue Kaikai, recently  said that 'Our traditions must be respected and the government will not interfere in secret societal matters as long as they do not pose a threat to national security or infringe on the rights of anyone without due cause.'"
From throwing rocks at MSF workers to "rescuing" patients from healthcare centres, community resistance has been a factor in the West African Ebola outbreak. This reflects a gap between not just the ill and their would-be healers, but between the governed and their governors.
