在亚临床感染期间，从5头牛的血液中共分离出14株赤羽病毒。从其中4只动物中连续分离出该病毒，表明病毒血症至少持续3或4天。感染小牛血清中的赤羽病毒中和抗体在病毒血症后4 - 5天达到初始峰值滴度32 - 256，但随后进一步上升至64 - 512。从同一时期附近采集的短库蠓（Culicoides brevitar）中分离到3株赤羽病毒。在这段时间里，吸血蠓的优势是brevitarsis。这些发现加强了C的情况。因此，认为brevitarsis是赤羽病毒的载体。
A total of 14 isolations of Akabane virus were made from the blood of five cattle during sub‐clinical infection. The serial isolation of this virus from four of these animals suggests a viraemia of at least 3 or 4 days. Neutralising antibody to Akabane virus in the serum of infected calves reached an initial peak titre of 32 to 256 four to five days after the viraemia but later rose further to a range of 64 to 512. Three isolations of Akabane virus were made fromCulicoides brevitarsiscollected nearby in the same period.C. brevitarsiswas the dominant haematophagous midge present during that time. These findings strengthen the case forC. brevitarsisto be considered as a vector of Akabane virus.
