Africa: Mobile App Halves Vaccinating Time to Curb Rabies

Namibia: Peugeot Will Export 'Once Issues Are Resolved'

Blantyre, Malawi — A mobile phone app is helping veterinarians to halve the time it takes to complete dog vaccination programmes in Malawi and could help curb rabies threat in African cities, a study shows.

The app known as World Veterinary Service Data Collection installed in mobile phones facilitates tracking of veterinary teams working remotely, collection of data and efficient coordination of vaccination teams in near real time.

Rabies transmitted by dogs kill almost 60,000 people each year globally, with most cases affecting Sub-Saharan Africa and India, according to another study. The WHO, World Organization for Animal Health and Food and Agriculture Organization have set the elimination of dog-mediated human rabies deaths by 2030.

Researchers using data collected through the app were able to modify Malawi’s Blantyre City rabies dog vaccination campaign to achieve vaccination of over 70 per cent of all the dogs in the city in nearly half the time and staff resources compared with previous campaigns.

“Achieving at least 70 per cent dog vaccination coverage annually is crucial for rabies control,” says Stella Mazeri, lead researcher and veterinary epidemiologist at the UK’s University of Edinburgh. “But it is often impossible to achieve [that] without employing expensive and labour-intensive door-to-door vaccination approaches.”

The study, published in the February issue of the Proceedings of the National Academy of Sciences (PNAS), assessed methods of mass dog vaccination that affect urban vaccination campaigns required to eliminate rabies in poor-resource settings such as Malawi.

Most successful vaccination programmes with coverages greater than 70 per cent have been dependent on a combined static point and door-to-door vaccination approaches that are expensive and time consuming, researchers say.

Thus, Mission Rabies, a charity organisation, collaborated with Blantyre Society for the Protection and Care of Animals and the University of Edinburgh to apply a data-driven approach using the smart phone app between 2015 and 2017 to record data on rabies vaccinations and access global positioning system locations.

Dagmar Mayer, Mission Rabies country manager in Malawi, says that they were able to increase the numbers of drop-in centres within around 800 metres of owners’ homes from 44 to 77.

The new campaign vaccinated more than 70 per cent of the more than 40,000 dogs in the city in 11 days compared with 20 days in a previous approach that did not use the app, the study says, adding that it also required 904 staff days instead of 1,719.
