Serum-neutralising antibodies to Akabane virus were found in a wide range of domestic animals in all countries of the Arabian Peninsula but the virus does not seem to be endemic there. Sentinel herds in Oman and N. Yemen did not detect any Akabane activity between August 1984-November 1986 and May 1983-November 1984, respectively. However, there is strong evidence to suggest that Akabane virus incursions have recently taken place in Kuwait, Saudi Arabia and Bahrain as neutralising antibodies were detected in 1-year-old cattle bled during 1986 in each of these countries. The possibility of windborne infected vectors, from virus-endemic areas, initiating these incursions into the Arabian Peninsula is discussed.
