â€˜The deformed lamb exhibits signs that are consistent with an early foetal development that went wrong as a result of a viral infection and nothing more" he said.
Dr Mrwebi said that the gestation period for a sheep is five months, and that meant that the particular sheep was conceived in late December 2016 or early January 2017.
He said it was a time of plentiful rainfall which brings with it many mosquitoes and midges which are carriers of viruses that cause the Rift Valley Fever in sheep.
Dr Mrwebi concluded"It is fair to assume, therefore, that the sheep was infected by the RVF virus.
"The resultant circulation of the virus in the blood found its way through the maternal blood into the uterus and the foetus, which was at a very critical stage of development.
"The infected foetus then, as a result, failed to form properly, leading to the deformity that it became.It does look like a human form but it is not part human at all" he said.
The department's veterinary officials is conducting a post-mortem and its results will be communicated to the public who are fearful in the remote area that witchcraft is at play.
A villager was quoted as saying: "The elders when they saw it said it was sent by the devil and was born after a coupling between a man and a sheep and then there was panic.
"Many people are afraid and will not be happy until it is burned" he said.
