Control of RFV including vaccination of livestock in Tanzania has being implemented after the onset of disease outbreak, and without informed risk-based resource-allocation decisions. To be cost-effective, strategic interventions including pre-emptive vaccination of livestock against RVF should be proportional to disease risk. Strengthening disease surveillance and animal identification, monitoring and traceability system can improve contact tracing during periods of outbreaks.
It is therefore recommended in this policy brief that the government should (i) establish the National RVF control programme; (ii) conduct a strategic pre-emptive vaccination of livestock between July and November by targeting the identified risk areas (northern, central-eastern zones and the eastern-southern parts of Lake Victoria zone of the country); (iii) During the same period of time establish sentinel surveillance sites in high risk districts to detect any impending epidemic; and (iv) operationalize the animal identification, monitoring and traceability system to improve contact tracing and monitoring of adherence to livestock movement by laws.
