ProMED list for information on outbreaks

By Sudip Bhandari | 02 Apr, 2015

I thought this would be an interesting resource for members here to know about and follow. ProMED is a moderated list serve that collects and distributes data on outbreaks. Link is attached below. There was a lot of time between the first case of ebola and any notice given to officials. ProMED aims to shorten the time. There are around 75,000 members now.

Yes, I have been using this list for information Sudip. They also offer
information relevant to facility opening and closings and briefs on health
care worker exposures from clinicians on the ground, assisting in
evacuations, for example. Some of the information, though offered as dry
reportage , can be quite unsettling .

Hello everybody, I have a question of a different nature than the current discussion. Does anybody have any information on serological surveys in the Ebola affected countries that can shed light on whether or not there is an asymptomatic infection state that confers immunity and may have contributed to the decline of the epidemic. Previous outbreaks in the DRC and Uganda have shown asymptomatic infections do occur, but their role in epidemic control is unclear. Many thanks, Fred Hartman

Both papers cited below, provide indirect evidence of Ebola Zaire in the area prior to and leading up to the present outbreak.

I have not seen any data on serosurveys of areas on the South East of Liberia, bordering the Tai forest near Ivory Coast. This would be an interesting area to do a sero survey as the Tai forest strain of Ebola was discovered here in 1994 . There was only one reported human case, however that case was identified and reported because it occurred in a zoologist exposed while doing a necropsy on primates that were dying from an unknown disease.

Primates are caught and consumed on a regular basis in this area, with large markets at the border villages between Liberia and Ivory Coast. From what little health data we have from this area of dense jungle and few roads, there is high mortality and morbidity in the general population with little access to formal health care. There very well could have been other cases of Tai forest Ebola that were never seen by the health system. The current Ebola Zaire outbreak barely touched this area, never flaring up, but the poor transportation infrastructure here was thought to play a role. It may have been that the lack of roads decreased the chance of Ebola arriving here but also that the population had some preexisiting protection from past exposure to Tai forest strain which assisted them as well. This is pure speculation on my part, so please take it in that spirit.

If you find other information on this please share it as it is a very interesting subject.
