Dear Paul,
I would wish to all the colleagues who raised the issue “endemicity” of the disease. Indeed, as I previously said over 60% of African countries regular reported
the diseases over the past 5 or 6 years. The disease was 2nd and 3rd commonly reported diseases in 2011 and 2012 and most likely to be 1st one in 2013. But unfortunately key epidemiological informations such are incidence,
mortality, morbidity, geographical distribution are missing. Only the number of outbreak are mentioned and very often not all the countries are providing the number of outbreaks, number of death, number of destroyed and animal as well as number of animal slaughters
or vaccinated.
Therefore, the establishment of both the epidemiological status and socio economic impact is critical for providing evidence-based information to guide decision
making in the disease control and eradication.
Otherwise from African perspective, there is growing political support for eradication as control will have certainly positive impact on livelihood and nutritional
security of small holder farmers and resilience of livestock-dependent communities including greater Access to markets.

Subject: From Dr Serge Nzeitchueng on endemicity and epidemiological evidence. With moderator's comments.
I concur with the questions from Drs Taylor and Kivaria.
The word “endemic” has been mentioned several times through this forum and it seems like the assumption behind the “endemic” means high mortality. It is a mistake to think that way because a disease can be endemic with a low incidence and high morality or high
incidence and low mortality or low incidence and low mortality. It is good to know that in Africa, 33 countries out of 54 have reported the disease in 2012 and I am wondering whether those countries can provide incidence information among others, but key epidemiological
informations which are part of the evidences driving the decision whether we want to control or eradicate a disease.
If in our countries there is institutional framework and strategy for prevention and control HIV/AIDS it is because there are evidences-based supporting the need to invest in prevention and control of HIV/AIDS.
About PPR, what are the epidemiological, economical and more importantly food security EVIDENCES we must provide to the policy maker in order to invest into control OR eradication of PPR?

I am not sure that everyone is actually assuming high mortality when they use the term
endemic. Perhaps some of you who have contributed on this can give us your views? What is the disease "pattern" that you see in endemic areas?
