DNA from ATCV-1 has been isolated from the mucous membranes of the noses of humans. In both humans and mice, the presence of ATCV-1 on the
oropharyngeal mucosa was associated with lower scores in tests of cognitive and motor skills. Injection of purified algal virus ATCV-1 intracranially results in long-lasting cognitive and behavioural effects in mice via induction of inflammatory factors. ==References==
