Epidemiology and surveillance of human animal-bite injuries and rabies post-exposure prophylaxis, in selected counties in Kenya, 2011-2016.

ABSTRACT: BACKGROUND:Human animal-bite injuries are a serious public health problem due to associated risk for rabies virus exposure. Animal-bite injuries especially dog bites are useful indicators for assessing the risk of rabies virus transmission and need for rabies post exposure prophylaxis (PEP). Understanding the epidemiology and surveillance of animal bites and rabies post-exposure prophylaxis is critical in implementing Kenya's national rabies elimination strategy. We aimed to describe the incidence of human animal-bite injuries, patient/biting animal characteristics, uptake of rabies PEP and factors associated with animal bite incidents. METHODS:We reviewed animal bite records from outpatient and anti-rabies vaccine (ARV) registers of 17 health facilities from five counties. An animal bite was defined as an entry of an animal bite of the class mammal including humans in registers in a person of any age from January 2011 to December 2016. We collected demographic and information on PEP uptake. We calculated descriptive statistics, odds ratios (OR) and 95% confidence interval (CI) to examine factors associated with being an animal bite case-patient. We also calculated incidence of animal bites using health facility catchment population for year 2016 as the denominator. RESULTS:We analyzed 7307 records. The median age was 22 years (IQR?=?31 years); there were 4019 (55%) male and age?

Project description:BackgroundRabies is invariably a fatal disease. Appropriate wound treatment and prompt rabies post-exposure prophylaxis (PEP) are of great importance to rabies prevention. The objective of this study was to investigate the prevalence and influencing factors of improper wound treatment and delay of rabies PEP after an animal bite in Wuhan, China.MethodologyThis cross-sectional study was conducted among animal bite victims visiting rabies prevention clinics (RPCs). We selected respondents by a multistage sampling technique. A face-to-face interview was conducted to investigate whether the wound was treated properly and the time disparity between injury and attendance to the RPCs. Determinants of improper wound treatment and delay of rabies PEP were identified by a stepwise multivariate logistic regression analysis.Principal findingsIn total, 1,015 animal bite victims (564 women and 451 men) responded to the questionnaire, and the response rate was 93.98%. Overall, 81.2% of animal bite victims treated their wounds improperly after suspected rabies exposure, and 35.3% of animal bite victims delayed the initiation of PEP. Males (OR = 1.871, 95% CI: 1.318-2.656), residents without college education (OR = 1.698, 95% CI: 1.203-2.396), participants liking to play with animals (OR = 1.554, 95% CI: 1.089-2.216), and people who knew the fatality of rabies (OR = 1.577, 95% CI: 1.096-2.270), were more likely to treat wounds improperly after an animal bite. Patients aged 15-44 years (OR = 2.324, 95% CI: 1.457-3.707), who were bitten or scratched by a domestic animal (OR = 1.696, 95% CI: 1.103-2.608) and people who knew the incubation period of rabies (OR = 1.844, 95% CI: 1.279-2.659) were inclined to delay the initiation of PEP.ConclusionsOur investigation shows that improper wound treatment and delayed PEP is common among animal bite victims, although RPCs is in close proximity and PEP is affordable. The lack of knowledge and poor awareness might be the main reason for improper PEP. Educational programs and awareness raising campaigns should be a priority to prevent rabies, especially targeting males, the less educated and those aged 15-44 years.

Project description:Rabies is a fatal zoonotic disease that causes a heavy burden on societies. Namibia, a country in southern Africa, is aiming at controlling the disease in its main reservoir, the domestic dog. To facilitate the implementation comprehensive information on the ecology and epidemiology of the disease and surveillance is of utmost importance. The study presented assesses the baseline data for both human and animal rabies surveillance in Namibia in recent times and establishes correlations with ecological and socio-economic data in order to provide an up-to-date picture on the epidemiology of rabies in Namibia. For instance, it was important to identify the main drivers in the epidemiology, and whether the control strategy by mass vaccination of dogs is undermined by cycles of rabies in wildlife. Rabies in humans was reported mainly from the Northern Communal Areas (NCAs), with a total of 113 cases from 2011 to 2017, representing an incidence of between 1.0 and 2.4 annual human rabies deaths per 100,000 inhabitants. Kavango, the region with the highest human rabies incidence was also the region with the lowest animal rabies surveillance intensity. Generally, the vast majority (77%) of dog samples originated from communal farm land, followed by urban areas (17%), while only a small fraction (3%) was submitted from freehold farm areas. In contrast, kudu and eland submissions were almost exclusively from freehold farmland (76%) and urban areas (19%), whereas the submission of cattle samples was evenly distributed among freehold farms (46%) and communal farm land (46%). The likelihood of sample submission decreased exponentially with distance to one of the two laboratories. Overall, 67% (N = 1,907) of all samples submitted tested rabies-positive, with the highest positivity rate observed in kudus (89%) and jackals (87%). The transmission cycle of rabies in dogs appears restricted to the northern communal areas of Namibia, whilst rabies in wildlife species is predominately reported from farmland in central Namibia, mostly affecting kudu (Tragelaphus strepsiceros) and livestock with a likely reservoir in wildlife canids such as jackals or bat-eared foxes. The analysis confirms the presence of two independent transmission cycles in Namibia with little geographic overlap, thus allowing for a sustainable control of rabies in dogs in the NCAs.

Project description:BACKGROUND:Injuries to tendons and ligaments make up a large portion of musculoskeletal injuries, and contribute to significant morbidity and healthcare costs. However, there is currently a poor understanding of the burden of these injuries at a population level. The purpose of this study was to quantify the burden and distribution of tendon and ligament injuries in the Aotearoa/New Zealand population. METHODS:Using the Accident Compensation Corporation (ACC, a no fault comprehensive compensation scheme encompassing all of Aotearoa/New Zealand; population in 2013 4.4 million) database, data specific to tendon and ligament injuries were identified between July 2010 and June 2016. The total number of claims made and the total cost of these claims per financial year were analyzed. Injuries were categorized by anatomical site, gender, ethnicity and age of the claimant. RESULTS:During the 6-year study period, the total number of tendon and ligament injury claims was 1,112,077, with a total cost of over $1.4 billion NZD. There was a 16.2% increase in the number of claims, and a 40% increase in the total cost of these injuries during this period. The majority of claims were made by people of European ethnicity, whilst the number of claims made by people of Asian ethnicity increased at the greatest rate; 52% (from 9047 claims in 2011) during the 6-year study period. Interestingly, M?ori (Indigenous New Zealanders) maintained the highest average cost per claim ($1614.05 NZD); 13% more than the overall average cost per claim ($1262.12 NZD). The most common sites of injury were the shoulder and knee; these injuries were also the greatest contributors to overall cost. The total costs of injuries peaked in claimants aged 40-54, irrespective of the number of claims made for that age group. CONCLUSIONS:Health and economic burdens of tendon and ligament injuries in Aotearoa/New Zealand are rising. The high healthcare costs underscore the urgent need for multifaceted interventions to reduce the incidence and improve clinical outcomes of tendon and ligament injuries.
