Implementation of high coverage mass rabies vaccination in rural Uganda using predominantly static point methodology.

Abstract

Despite successful eradication programmes in many regions, rabies remains responsible for approximately 60,000 human deaths annually, and no country in Africa is rabies-free. Dogs are the principal reservoir of the virus in Africa and the World Health Organisation recommends that at least 70% of the dog population be vaccinated in order to break the transmission cycle. Most attempts at mass rabies vaccinations in Africa have failed to vaccinate high numbers of dogs at a high coverage. Successful studies have often used a door-to-door (DTD) approach, which is logistically challenging and expensive compared to a static point (SP) approach. Mission Rabies has successfully implemented a combined SP and DTD method in cities in India and Malawi. This campaign used a combined methodology in rural Uganda, starting with a SP campaign, followed by a DTD campaign, and then subsequent transect surveys to assess vaccination coverage. This was facilitated by the use of a smartphone application which recorded all vaccinations and survey responses along with their Global Positioning System location. A total of 4172 dogs were vaccinated in 7 days, attaining an estimated 88.4% coverage. This campaign is of particular note as 95.9% of the vaccinations were performed at SPs. The human-to-dog ratio was 4.9 with a mean dogs per house of 1.2. Most dogs were owned (93.7%). This demonstrates that high-number, high-coverage vaccination is achievable in rural Uganda and provides data that may refine future campaign approaches.
