  • Zika virus is a mosquito-borne flavivirus that was first identified in Uganda in 1947 in monkeys. 
  • It was later identified in humans in 1952 in Uganda and the United Republic of Tanzania.
  • ZVD is caused by a virus transmitted primarily by Aedes mosquitoes (AM), mainly Aedes aegypti.
    • This is the same mosquito that transmits dengue, chikungunya and yellow fever.
  • Transmission: From mother to fetus during pregnancy, through sexual contact, transfusion of blood and blood products, and organ transplantation.
  • Symptoms:
    • Fever, rash, conjunctivitis, muscle and joint pain, malaise or headache. 
    • Most people with Zika virus infection do not develop 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.
  • Treatment:
    • There is no vaccine or medicine for Zika. 
    • The focus is on relieving symptoms and includes rest, rehydration and acetaminophen for fever and pain.
