Rift Valley Fever (RVF), as it's popularly known in Tanzania, is a mosquito-borne disease spread from infected livestock to humans.
Mwakyusa said the disease also claimed about 154 lives in less than three months on the border region of Kenya. At least 41 people are still receiving treatment in hospitals in Tanzania after showing symptoms of RVF.
"The disease was first reported in Arusha and has not spread to Dodoma where we are recording many new cases," Mwakyusa said, according to BBC News.
Veterinary officials in Kenya said the ongoing domestic animal vaccination campaign could be the cause of the rampant spread of RVF.
The RVF virus is transferred to humans from livestock through the aedes mosquito, a species originally found in tropical and subtropical zones. Symptoms include liver failure and bleeding from the nose and mouth.
