Zika Virus : A quick guide

Zika virus is an emerging mosquito-borne virus that was first identified in Uganda in 1947 in rhesus monkeys through a monitoring network of sylvatic yellow fever. It was subsequently identified in humans in 1952 in Uganda and the United Republic of Tanzania. Outbreaks of Zika virus disease have been recorded in Africa, the Americas, Asia and the Pacific.




The virus spread eastward across the Pacific Ocean between 2013 and 2014 to French Polynesia, New Caledonia, the Cook Islands, and Easter Island, and in 2015 to Mexico, Central America, the Caribbean, and South America, where the Zika outbreak has reached pandemic levels.[8] As of 2016, the illness cannot be prevented by drugs or vaccines.As of February 2016, there is evidence that Zika fever in pregnant women is associated with intrauterine growth restriction including abnormal brain development in their fetuses through mother-to-child transmission of the virus, which may result in miscarriage or microcephaly. There is however no proof yet that the Zika virus causes microcephaly.A link has been established with neurologic conditions in infected adults, including Guillain–Barré syndrome.

In January 2016, the U.S. Centers for Disease Control and Prevention (CDC) issued travel guidance on affected countries, including the use of enhanced precautions, and guidelines for pregnant women including considering postponing travel. Other governments or health agencies soon issued similar travel warnings,while Colombia, the Dominican Republic, Ecuador, El Salvador, and Jamaica advised women to postpone getting pregnant until more is known about the risks.

Signs and Symptoms

The incubation period (the time from exposure to symptoms) of Zika virus disease is not clear, but is likely to be a few days. The symptoms are similar to other arbovirus infections such as dengue, and include fever, skin rashes, conjunctivitis, muscle and joint pain, malaise, and headache. These symptoms are usually mild and last for 2-7 days.

Pain areas: in the back of the eyes, joints, or muscles
Whole body: fatigue, fever, chills, loss of appetite, or sweating
Also common: eye redness, headache, skin rash, or vomiting
