On 14 January two blood samples tested at the UVRI were positive for IgG against RVFV, one was IgG and IgM positive from suspected cases in Yirol West, this lead to 3 confirmed RVF cases, however 4 other were negative for both PCR and serology.


Blood samples from 7 animals ( sheep 2, goats 2 and cattle 3) have been collected and sent on 14th January to UVRI, for RVF testing and results are pending.
