High rabies burden and low vaccination status among dogs inflicting bite in Addis Ababa: an urgent call for action.

INTRODUCTION: Rabies remains a global threat, killing approximately 60,000 people every year. In Ethiopia, dogs are the main reservoir of the disease. Animals also estimate the burden of the disease. METHODOLOGY: Data from 2016 to 2020 were extracted from a rabies cases recording book of the Ethiopian Public Health Institute. Proportions and trends over time were analyzed. Brain samples of dogs were diagnosed with a Fluorescent Anti Body test. RESULTS: A total of 6,001 dogs inflicting bites were brought to the laboratory. A high proportion of dogs 4,389 73.14% were not vaccinated. The total number of dogs brought to the laboratory was decreasing over the last five years. Among 1,216 dog brain samples examined 855 (70.3%) confirmed rabies. The proportion of rabies cases was increasing from 8.5% in 2016 and 32.6% in 2020. The highest rabies proportion (33.8%) was reported in 2018. Out of the total (2,156) dogs inflicting bites and observed for 10 days, only 468 (21.7%) of the observation report was tracked and reported. CONCLUSIONS: There is a high proportion of rabies in dogs inflicting bites in Addis Ababa. The findings are alarming with seven out of ten dogs diagnosed being infected with rabies. Only two dogs were vaccinated out of ten dogs inflicting bites. Rabies became a serious public health problem in the city that needs urgent health action from all sectors including the city administration.

Prevalence, aetiology and risk factors of mastitis of dairy cows kept under extensive management system in west Wollega, western Oromia, Ethiopia.

INTRODUCTION: Mastitis is an inflammation of the mammary gland that could either be clinical or subclinical, and can be caused by infectious agents. It has different aetiological pathogens such as Staphylococcus aureus, Streptococcus agalactiae, Escherichia coli that pose different economic and health impacts. In Ethiopia, previous studies on mastitis have been focused on semi-intensive and intensive dairy production system. The objectives of this study were therefore to estimate prevalence, aetiology of causative pathogens and identify different risk factors of mastitis in extensive management systems. A total of 532 lactating cows were randomly selected for a cross-sectional study carried out in four districts of west Wollega, western Oromia, Ethiopia. RESULT: Based on the clinical examination and California mastitis test, 39.67% overall prevalence of mastitis on cow level was recorded. Of them, 16.70% and 22.70% were clinical and subclinical mastitis, respectively. Among 2,128 quarters examined 210 were blind teats. The associated risk factors age ≥8 years (16.35%), parity 1-3 calving (27.63%), milk yield 1-2 litres (21.98%), lactation stage <4 months (18.04%) and tick infestation (26.70%) were significantly associated in the occurrence of mastitis. Staphylococcus spp. (15.60%) were the dominant bacteria isolated from collected mastitic milk. CONCLUSION: Mastitis is an important disease for dairy cows kept under an extensive management system. Its occurrence is determined by risk factors like age, parity, milk yield, lactation stage and tick infestation. This study is indicated Staphylococcus species as the major bacteria isolated from mastitic milk. This study warrants further study on the prevalence, aetiology, economic impact and potential risk factors of mastitis in dairy cows kept in extensive production system.

Situation of Rabies in Ethiopia: A Five-Year Retrospective Study of Human Rabies in Addis Ababa and the Surrounding Regions.

OBJECTIVE: The study objective was to estimate the burden of human rabies in Ethiopia from 2015-2019. Study Design. A descriptive study design was applied to measure the size of the problem. METHOD: Retrospective data were used from the Ethiopian Public Health Institute rabies case record book that was registered between 2015 to 2019. RESULT: Eighty-seven (87) cases of human rabies were diagnosed clinically in the Ethiopian Public Health Institute over the period of five years (2015-2019) with 100% case fatality. Of these, 83 (95.4%) cases were attributed to dog bites, whereas 1 (1.1%) to a cat and 3 (3.4%) to wild animals. The fatalities were from Oromia (n = 51 (58.6%), 13 (14.9%) were from Amhara, 15 (17.2%) were from Addis Ababa, and 8 (9.2%) from the Southern region. All referred cases had no record of immunization against rabies except eight. Ineffective postexposure treatment was the reason for 5 (5.7%) deaths. Out of 1,652 brain samples of different animals, mainly dogs, submitted for examination, 1,122 (68%) were found to be positive for rabies by the FAT. Dog bites were more common among males than females. The number of dog bite victims who had visited the EPHI counseling office and recommended to take postexposure prophylaxis against rabies both from Addis Ababa and the surrounding areas were 9,592 and 4,192, respectively. Out of these, 5,708 were males and 3,884 females for the capital Addis Ababa. Similarly, 2,439 males and 1,753 females account for areas surrounding Addis Ababa. Among those exposed from Addis Ababa, 1,079 (11.2%) were in the age group less than five, 1696 (17.7%) were in the age group 6-13, and 6,817 (71.1%) in the age group 14 and greater. Victims from outside of the capital Addis Ababa account for 644 (15.4%) for the age group less than 5 years, 964 (23%) for the age group 6-13 and, 2,584 (61.6%) for the age group 14 and greater. CONCLUSION: Mechanisms must be sought to reduce the cost of PEP and means of obtaining funds so as to initiate timely treatment for rabies exposed individuals of low socioeconomic status. Besides prevention, strategies should focus on public education and strict dog population control.
