All about Zika virus

Zika virus was first identified in monkeys, after a century the virus was detected in humans. Zika is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). Ae. Aegypti is a Yellow fever mosquito, sneaky biter, main dengue vector worldwide and coming to Ae. Albopictus is a Asian tiger mosquito, aggressive biter, mostly a secondary vector. These mosquitoes bite during the day and night. Usually the symptoms are acute onset of fever, maculopapular rash, arthralgia, or conjunctivitis, who traveled to areas with ongoing transmission in the 2 weeks preceding illness onset. Because Dengue and Chikungunya virus infections share a similar geographic distribution with Zika virus and symptoms of infection are same. Although the exact incubation period is unknown, the virus appears to be present for some days before full symptoms are developed. Zika virus can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause a birth defect called microcephaly and other severe fetal brain defects.

This Reverse Transcription-Polymerase Chain Reaction (RT-PCR) test is carried out to look for viral RNA in the fluids of a person suspected of having the Zika virus. The Zika virus can be in a person’s urine for up to ten days after symptoms of the disease show. Alongside this an immunoglobulin (Ig) M ELISA and plaque reduction test are used to identify Zika antibodies.
