Zika virus occurs in tropical areas with large mosquito populations and is known to circulate in Africa, the Americas, Southern Asia and Western Pacific. The virus was discovered in 1947, but for many years only sporadic human cases were detected in Africa and Southern Asia.
In 2007, the first documented outbreak of Zika virus disease occurred in the Pacific. Since 2013, cases and outbreaks of the disease have been reported from the Western Pacific, the Americas and Africa. In May 2017, WHO confirmed India’s first cases in Ahmedabad.
People catch Zika virus by being bitten by an infected Aedes mosquito – the same type of mosquito that spreads dengue, chikungunya and yellow fever. The Aedes mosquito is a weak flyer; it cannot fly more than 400 meters. But it may inadvertently be transported by humans from one place to another, for example, in the back of the car and plants.
During the first outbreak of Zika from 2013 - 2014 in French Polynesia, which also coincided with an ongoing outbreak of dengue, national health authorities reported an unusual increase in Guillain-Barré syndrome. It is a condition in which the body’s immune system attacks part of the nervous system. It can be caused by a number of viruses and can affect people of any age.
