**Nairobi, Kenya** – A new tick-borne virus, tentatively named Kinna virus (KIV), has been discovered in Isiolo County, Kenya. The virus, belonging to the _Phenuiviridae_ family and _Bandavirus_ genus, was isolated from _Amblyomma gemma_ ticks collected from domestic animals in pastoralist communities.
The study, published in PLOS ONE, highlights the increasing incidence of tick-borne diseases globally, particularly in areas experiencing climate change and the expansion of tick vectors. KIV shares close genetic relatedness with Guertu virus, another emerging tick-borne virus, exhibiting significant similarity in its genome structure and protein sequences.
**Potential for Human and Animal Disease**
Researchers found that KIV can infect mammalian cells and is lethal to mice, indicating its potential to cause disease in humans and animals. A serological survey revealed that 38.6% of human sera from communities in the region tested positive for neutralizing antibodies against KIV, suggesting widespread previous exposure to the virus.
**Risk Factors and Transmission**
The study identified several risk factors associated with KIV infection, including age, sub-county of residence, and contact with cattle. Farmers and herdsmen, who often interact with livestock, are particularly vulnerable. The virus’s transmission likely occurs through tick bites, with the potential for zoonotic spread from wild animals as well.
**Public Health Implications**
The discovery of KIV emphasizes the need for enhanced surveillance of tick-borne viruses in high-risk ecosystems, particularly in areas where humans, livestock, and wildlife interact. Further research is essential to understand the full clinical presentation of KIV infection, identify potential reservoirs and hosts, and develop effective diagnostic tools and control strategies.
**A One Health Approach**
The researchers highlight the importance of a “One Health” approach, recognizing the interconnectedness of human, animal, and environmental health, in addressing the threat posed by KIV. Collaborative efforts between public health officials, veterinarians, and wildlife experts are crucial to effectively monitor and control emerging tick-borne diseases like KIV.
