Panafrican Animal Health Yearbook 2011.
In 2011, 42 Member States (MS) of the African Union (AU) submitted their disease reports to the Interafrican Bureau for Animal Resources of African Union (AU-IBAR). The number of countries that reported their disease situation to AU-IBAR has decreased by 11.68% from 49 (92.45%) in 2010 to 42 (80.77%) in 2011. A total of 91 animal diseases were recorded in 2011 involving 24,201 outbreaks, and 2,025,190 cases, causing 651,275 deaths and the slaughtering and destruction of 225,789 and 262,339 animals, respectively. The highest mortality rate was registered on avian species (61.96%) followed by swine (19.85%), small ruminants (SMR) (14.10%) and cattle (3.53%). The most widely distributed transboundary animal diseases (TADs) based on the number of countries affected include Newcastle Disease (ND), lumpy skin disease (LSD), Peste des Petits Ruminants (PPR), foot and mouth disease (FMD), African swine fever (ASF) and contagious bovine pleuropneumonia (CBPP) in a decreasing order. However based on the number of epidemiological units (number of outbreaks) affected, LSD appeared the most prevalent followed by PPR, ND, FMD, African horse sickness (AHS), sheep & goat Pox (SGP), ASF and CBPP in a decreasing order. In the same order, the most reported deadly TADs were ND, ASF, PPR CBPP, FMD and SGP. Among the diseases other than TADs, Rabies was the most widely distributed disease geographically, affecting 34 out of the 42 countries that submitted reports, followed by blackleg (BQ), trypanosomosis, tuberculosis (TB), anthrax and brucellosis. Contrary to 2010, where in terms of prevalence, rabies was recorded with the highest number of outbreaks, in 2011 theileriosis (1,942) and trypanosomosis (1,629) had the largest number of outbreaks. On the other hand the largest number of cases was caused by trypanosomosis, brucellosis, infectious bursal diseases (IBD), babesiosis, theileriosis, mange, anaplasmosis, pasteurellosis and blackleg, in a decreasing order. Low quality of reports, delay in submission of the reports and decrease in the number of reporting countries remained the main challenges responsible for the lack of better understanding of the epidemiology of animal diseases on the continent. The rolling out of the Animal Resource Information System (ARIS-2) in 2012 is expected to address such challenges. Disease control interventions of AU-IBAR through the VACNADA and LEISOM projects were successfully concluded in 2011. These projects enabled the vaccination of 49,185,953 animals against PPR, CCPP and CBPP in the targeted countries. Additionally, support was provided to eight vaccine producing laboratories in order to enhance their production capacity and improve the quality of vaccines produced, as well as enable AU-PANVAC to acquire a Bio-safety Level 3 (BSL3) laboratory.
