Zika virus is a single-stranded RNA virus of the Flaviviridae family, genus Flavivirus. Zika virus is transmitted to humans primarily through the bite of an infected Aedes species mosquito. The mosquito vectors typically breed in domestic water-holding containers; they are aggressive daytime biters and feed both indoors and outdoors near dwellings. Nonhuman and human primates are likely the main reservoirs of the virus, and anthroponotic (human-to-vector-to-human) transmission occurs during outbreaks.
Based on the typical clinical features, the differential diagnosis for Zika virus infection is broad. In addition to dengue, other considerations includel eptospirosis, malaria, rickettsia, group A streptococcus, rubella, measles, and parvovirus, enter
