Background: Rabies, a viral disease that affects all warm-blooded animals, is widespread in many regions of the world. Human rabies, transmitted by dogs is an important public health issue in Ethiopia. To-date, effective rabies control program still remains to be a reality and needs to be strengthened.. Conclusion:The recorded data showed the underestimate of rabies diagnosis, post exposure prophylaxis and fatal human cases, which could be attributed due to the absence of national rabies surveillance system. Therefore, It is of paramount importance to assess and map the national picture of rabies within a given time interval to launch a national rabies control strategy. [Ethiop. J. Health Dev. 2010;24(2):127-132]

Detailed postmortem examinations were conducted to evaluate the efficiency of meat inspection procedures and to determine the distribution of lesions in Mycobacterium bovis-infected cattle. The study involved routine inspection at slaughter, collection of tissues for detailed examination in the laboratory, and bacteriological examination to identify M. bovis. Additionally, a 10-year (1992--2001) meat inspection record was analysed to determine tuberculosis trends in the past decade. chi2-Test and simple regression were used to analyse the data. Out of 1350 cattle examined, 1.5% were found with tuberculous lesions. Routine abattoir inspection detected only 55% of cattle with confirmed lesions. Fifty-four per cent of tuberculous lesions were found in the lungs and thoracic lymph nodes, 23% in the lymph nodes of the head, and the remaining 23% in the mesenteric and other lymph nodes of the carcase. M. bovis was additionally isolated from an animal that had no gross lesions of tuberculosis. On average, the annual rate of whole-carcase condemnation due to generalized tuberculosis was 0.024% and it has increased annually by 0.34% over the past decade. The rate of whole-carcase condemnation indicates a high degree of TB transmission and requires immediate attention from both the economic and public health points of view. The lower sensitivity of routine abattoir inspection confirms the importance of improving necropsy procedures.

The efficacy of the meat inspection procedures implemented for the detection of tuberculous cattle was evaluated by testing for bovine tuberculosis in 751 animals. The study involved routine inspection at slaughter, collection of tissues for detailed examination in the laboratory, and bacteriological investigation to identify Mycobacterium bovis. Of the 751 carcasses examined, 34 (4.5%) were found to have tuberculous lesions. Routine abattoir inspection detected only 29.4% of the carcasses with visible lesions. Eighty-four percent of the tuberculous lesions were found in the lungs and thoracic lymph nodes, 11.5% in the lymph nodes of the head, and the remaining 4.5% in the mesenteric and other lymph nodes of the carcasses. In addition, M. bovis was isolated from a carcass that presented no gross tuberculosis lesions. The low sensitivity of routine abattoir inspection demonstrates that existing necropsy procedures should be improved.

The study was conducted from May 2003 to August 2003 in Addis Ababa with the objective of understanding the distribution of stray and owned dogs, dog ownership patterns and attitudes of people towards rabies and its prevention and control methods. A total of 2390 households were selected from 6 Sub Cities of Addis Ababa using stratified random sampling and were interviewed using structured questionnaires. From the total households interviewed, 969 (40.5%) of them were known to own one or more dogs, and the total number of owned dogs was estimated to be 225,078. Male dogs make up 1042 (78.4%) of the total owned dogs. Almost half of all the dogs 463 (47.8%) were tied only for some time during the day whereas 320 (33.1%) of the dogs were not tied at all and freely move from place to place and contribute to high dog bites in human beings and for the widespread occurrence of canine rabies in Addis Ababa. Six hundred fifty five (67.6%) of the interviewed households who owned dogs had a well fenced house. Most of the owned dogs 856 (88.4%) get their food from their owners and only 321 (33.3%) of the owners reported that they let their dogs to be vaccinated while the majority of the owners 644 (66.5%) do not let their dogs vaccinated regularly. A significant proportion of the interviewed households 2,323 (97.2%), (P < 0.05) indicated that they have the knowledge that dogs, cats and other animals can transmit rabies to humans and 1,752 (73.4%) of the households replied that rabies can be transmitted through
