Zika virus
Transmission electron micrograph (TEM) of virus particles are 40 nm in diameter, with an outer envelope, and an inner dense core. ZIKV is an RNA virus containing 10,794 nucleotides encoding 3,419 amino acids.
Zika virus (ZIKV) is a mosquito-borne flavivirus related to dengue virus first isolated from a rhesus monkey in Zika forest, Uganda (1947). Transmitted by mosquitoes (Aedes aegypti) it was then identified in humans in Nigeria in 1954 and subsequently in South America, Asia and Pacific regions. More recently in Australia from returning travellers. Mosquito bites lead to an initial infection of skin cells. The virus may also be transmitted transplacentally or during delivery. Some limited evidence, from Brazil, for association with microcephaly.
