About Zika:

  • The Zika virus is predominantly transmitted by infected mosquitoes from the Aedes genus, mainly Aedes aegypti. The Aedes mosquitoes also spread dengue, chikungunya and yellow fever.
  • The virus was first identified in Uganda in 1947 in monkeys.



  • Apart from the mosquitoes, an infected person can also spread the virus.



  • Generally, the symptoms include fever, rash, conjunctivitis, muscle and joint pain, malaise, or headache. It lasts for about two to seven days. Most infected people do not develop any symptoms.
  • Zika virus infection during pregnancy can cause infants to be born with microcephaly (smaller than normal head size) and other congenital malformations, known as congenital Zika syndrome.
  • It has no treatment or vaccine. Instead, the focus is on relieving symptoms and includes rest, rehydration and acetaminophen for fever and pain.
