What is 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. Sporadic cases have been reported throughout the world since the 1960s, but the first outbreak happened only in 2007 in the Island of Yap in the Pacific.
  • 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.
  • Fears around Zika primarily involve microcephaly, especially when pregnant women are infected. Generally, the virus is not considered dangerous to anyone other than pregnant women. Some countries that have had a Zika outbreak, including Brazil, reported a steep increase in Guillain-Barré syndrome — a neurological disorder that could lead to paralysis and death, according to the World Health Organization (WHO).
  • 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.
  • A history of Zika virus in India
  • In India, Zika virus was first recorded in 1952-53. The latest major outbreak was in 2018, when 80 cases were reported in Rajasthan around the months of September and October. Prior to this, three cases were detected in Bapunagar area in Gujarat’s Ahmedabad district in May 2017. One case was also reported from Krishnagiri district on Tamil Nadu in July 2017.
