Canine babesiosis treatment rates in South African veterinary clinics between 2011 and 2016

South African veterinarians report the perception of a multi-year decline in the number of dogs presenting with clinical babesiosis, a common and serious disease of dogs in the country. This study tested this observation through analysis of veterinary hospital medical records from 2011 through 2016.

Medical records were collected from 44 participating South African veterinary hospitals. The collected medical records were searched to enumerate the number of Babesia-specific medication treatments administered to dogs at all participating hospitals. A healthcare use rate was calculated for canine babesiosis treatment for each calendar year from 2011 to 2016. The healthcare use rate numerator was the total number of canine babesiosis treatments and the denominator was the total dog visits to all participating veterinary practices over the same period.

There were 2.6 million dog visits to 44 participating veterinary practices between 2011 and 2016. The number of canine babesiosis treatments for each year in chronological order starting with 2011 was: 2957; 2679; 2456; 2746; 2272; and 1592. South African regions with the highest number of canine babesiosis treatments were Gauteng, Free State and Mpumalanga. The overall calculated healthcare use rate for canine babesiosis treatment declined 72% over the study period from 1.18% in 2011 to 0.33% in 2016. The steepest decline of 31% was observed between 2015 and 2016.

South African veterinary practices saw a decline in canine babesiosis treatment administration from 2011 to 2016 with the steepest decline beginning in 2015.
