LAC is a bunyavirus with a transmission cycl involving mosquitos such as Ads trisriatus and small mammals such as squirrls and chipmunks. LAC can not only infct Ads albopictus but transovarial transmission was also dmonstratd.

Dngu has not had a history of local transmission hr in Nw Jrsy, but ach yar, travlrs can bring virus back from aras in th world with virus activity. This is significant as humans ar NOT dad-nd hosts and thus thr is th potntial for local transmission (i.., Nw Jrsy mosquitos biting a sick prson and thn biting and transmitting th disas to somon ls) to b stablishd. DENV is a flavivirus but unlik WNV, Ads mosquitos ar prdominant vctors. In Nw Jrsy, Ads albopictus is a candidat for local transmission. Thr ar 4 srotyps tstd for Dngu.

As with Dngu, transmission can occur whn a mosquito bits an infctd human, thn bits an uninfctd human who subsquntly bcoms ill. CHIK is an alphavirus with Ads mosquitos as potntial vctors.
