4. Epidemiology of CQV (Origin and Transmission):
CQV was first isolated in 2004 from mosquitoes and reported during the
surveillance of arboviruses in acute pediatric encephalitis cases in
Vietnam (Bryant et al., 2005) and late in Uganda (Mossel et al., 2017).
Viruses of family Peribunyaviridae infect the vertebrates and
reside in a zoonotic infection cycle that spreads across livestock and
human beings through an arthropod intermediate (Saeed et al., 2001).
Globally, arboviruses (arthropod-borne viruses) have turned
into a major public health concern with the emergence and re-emergence
of arboviral diseases. Most of the arboviruses act as a zoonotic
spillover from an infected reservoir hosts (dogs, mosquitoes, birds, and
ruminants) to humans (accidental host) (Go et al., 2014; Bodewes and
Kuiken, 2018), i.e.,the spread of a pathogen from an infected vertebrate
to a human is caused by mosquito bite (Figure-2) (Whitmer et al., 2018).
