Zika Virus

Zika is a viral infection, spread by mosquitoes.
The vector is the Aedes aegypti mosquito, which also spreads dengue and chikungunya. Additionally, infected people can transmit Zika sexually.
First identified in Uganda in 1947 in monkeys, Zika was detected in humans five years later.
In 2015, a major outbreak in Brazil led to the revelation that Zika can be associated with microcephaly, a condition in which babies are born with small and underdeveloped brains.

Zika

Most people infected with the virus do not develop symptoms.
When they are manifested, the symptoms are similar to those of flu, including fever, bodyache, headache etc.
If the symptoms worsen, people should seek medical advice. Additional symptoms can include the occasional rash like in dengue, while some patients also have conjunctivitis.
The incubation period (the time from exposure to symptoms) of Zika virus disease is estimated to be 3-14 days.

Zika has no treatment or vaccine. The symptoms of Zika virus are mild and usually require rest, consumption of plenty of fluids, and common pain and fever medicines, the WHO says.

Governments take mosquito control measures such as spraying of pesticides, use of repellents etc. Because of the possibility of congenital abnormalities and sexual transmission, there is also focus on contraceptives.
The WHO requires countries to counsel sexually active men and women on the matter to minimise chances of conception at the time of an outbreak.
