Abstract

Background: Clinical Rabies is a widely distributed almost 100% fatal viral zoonotic disease. Most human rabies cases occur in developing countries, especially in Asia and Africa. It can be prevented by immunization, post exposure prophylaxis. Ethiopia is assumed to be among African countries with high incidence of human rabies exposure cases. However, there is limited documented data on the incidence of human rabies exposure in the study area in particular and in Ethiopia in general. Thus, this study aimed to determine the Incidence of Human Rabies Virus exposure in Northwestern Amhara, Ethiopia.

Methods: Retrospective cross-sectional study was conducted during August and September, 2017. The study was conducted at Addis Alem Hospital, a district level hospital in Bahir Dar. Data on human rabies exposure cases registered from September 1, 2015 to August 31, 2017 were collected from anti-rabies post exposure prophylaxis registration log book. Data was collected using a structured data collection questionnaire developed for this purpose. Descriptive statistics was used to describe relevant variables.

The results: A total of 924 human rabies exposure cases was recorded. The overall human rabies incidence per 100, 000 population was 6.5 in 2015 and 7.5 in 2016. Males (55.2%, 510/924) and children of age less than fifteen (46.3%, 428/924) were most affected groups. The majority of human rabies exposure cases (71.9%, 664/924) were from rural settings. Dogs were the principal sources of exposure (96.3%) followed by cat (1.5%) and donkey (1.3%). High incidence rate of rabies exposure was reported during spring (360, 39%) and summer (244, 26.4%) seasons. There was significant difference between rural and urban exposure cases (p = 0.001) in respect to the time of arrival to the hospital.

Conclusion: Taking these into account, a significant proportion of the population was exposed to rabies virus during the study years. There was high human rabies exposure rate in children and in the rural community. This shows the need for organizing preventive and control strategies and to build community awareness.
