约15%的盐沼蚊A.（Ochlerotatus）vigilax（Skuse）将罗斯河病毒的T48株从病毒血症供体机械地传播给未感染的受体乳鼠。来自布里斯班[澳大利亚]附近的受试人群对感染中度敏感（感染剂量中位数= 104.5 ± 0.001）。0.1乳鼠LD 50/蚊）。病毒在蚊子体内的快速增殖使其在摄入后4天开始传播，最大传播率为50-57%，发生在10天后。从A.对于vigilax卵巢和由父母感染的雌性饲养的后代，初步数据表明经卵巢传播是该病毒的潜在生存方式。
Some 15% of the saltmarsh mosquito, A. (Ochlerotatus) vigilax (Skuse) mechanically transmitted the T48 strain of Ross River virus from viremic donors to uninfected recipient suckling mice. The population tested from near Brisbane [Australia] was moderately susceptible to infection (median infective dose = 104.5.+-.0.1 suckling mouse LD50/mosquito) when fed virus diluted in blood on a cotton pledget. Rapid proliferation of the virus in the mosquito allowed transmission from 4 days after ingestion with maximum transmission of 50-57% occurring from 10 days. From assay of A. vigilax ovaries and of progeny reared from parentally-infected females, preliminary data suggest transovarial transmission as a potential survival method for this virus.
