  • Vectors
Epidemiological comments The outbreak of bovine babesiosis limited to the area of Tamoa is still being eradicated. No circulation of babesiosis was detected in 2019 and early 2020 in the affected farms. A total of 5138 serological tests were performed in 2019, of which nine were positive and several suspicious, but all tested negative in PCR (a total of 216 PCR tests were performed, all negative). Thus, although the outbreak cannot be closed, it remains localized to a restricted area and has not spread. The political will to eradicate this disease has been confirmed and a budget of 30 million CFP has been set aside for this purpose for 2020. A new decree setting out the sanitary measures for eradication will be proposed to the government for adoption on 24 June 2020. It confirms the measures for monitoring animals in the zone, reinforces the conditions for monitoring and slaughter of feral cattle and prohibits the establishment of new farms in the zone. It also updates the list of affected farms and properties, supplemented by a map highlighting the protection belt established around the farms at risk to prevent the spread of the disease via serological monitoring of all affected farms.
