Zika virus

Zika virus disease (ZVD) is a mosquito-borne disease transmitted by Aedes mosquitoes. The same mosquito also transmits three other vector-borne diseases -- dengue, chikungunya and yellow fever. It usually bites during day time.

The Zika virus disease is usually mild and requires no specific treatment. The most common symptoms are mild fever, skin rash, headache, muscle and joint pain and inflammation of the underside of the eyelid. These symptoms normally last for 2-7 days. If symptoms worsen, they should seek medical care and advice.

Pregnant women in general, including those who develop symptoms of Zika virus infection, should see their health-care provider for close monitoring of their pregnancy. Women who are planning to become pregnant should also take extra care to protect themselves from mosquito bites.

Protection against mosquito bites is a key measure to prevent Zika virus infection. Efforts to prevent mosquito bites include: use of insect repellent; cover as much of the body with long and light colour clothing; use physical barriers such as wire mesh on doors and windows; and empty, clean or cover containers that can hold water for mosquitoes breeding.
