TL;DR
Researchers found new combinations of viruses in horses and midges in South Africa, highlighting the need for ongoing surveillance.
Contribution
The study reports the detection of novel orthobunyavirus reassortants in horses and Culicoides midges in South Africa.
Findings
Shuni virus was detected in horses and ovine fetuses.
Shamonda and Caimito virus reassortants were identified in Culicoides midges.
Genomic surveillance is crucial for tracking orthobunyavirus infections in Africa.
Abstract
We detected Shuni virus in horses and ovine fetuses and Shamonda virus in a caprine fetus in South Africa. We identified a Shuni/Shamonda virus reassortant in a horse and Shuni/Caimito, Shamonda/Caimito, and Shamonda/Sango virus reassortants in Culicoides midges. Continued genomic surveillance will be needed to detect orthobunyavirus infections in Africa.
