The Ministry of Health (MOH), Singapore has been closely monitoring the Zika virus situation, and will be introducing several measures to enhance the surveillance of the disease and the protection of Singaporeans. We also urge all Singaporeans to take the appropriate precautions to prevent mosquito breeding as vector control is critical in preventing transmission and reducing the risk of the virus from taking root in Singapore.
Zika virus infection in humans has been reported since the 1950s. It is transmitted by the Aedes mosquito, identical to dengue. Only about one in five infections are symptomatic. Zika is generally a mild and self-limiting illness. Although rare, serious neurological complications have been reported. There is no vaccine or specific anti-viral drugs.
Travellers to countries with local transmission of the Zika virus should protect themselves from mosquito bites by wearing long, covered clothing, applying insect-repellent, and sleeping under mosquito nets or in rooms with wire-mesh screens to keep out mosquitoes. They should seek medical attention promptly if they become unwell.
While there is currently no evidence that pregnant women are more likely to get Zika virus infection, the consequences can be more serious if a pregnant woman is infected, as the Zika virus infection can cause microcephaly in the unborn foetus of pregnant women. As such, pregnant women should postpone non-essential travel to countries with ongoing outbreaks. They should reconsider their travel plans to areas that are not experiencing outbreaks but have reported local transmission of Zika virus. If they must travel to affected areas, they should undertake strict precautions against mosquito bites.
All travellers returning from areas with ongoing outbreaks of Zika should adopt safer sexual practices, e.g. consistent and correct use of condoms during sex, or consider abstinence for at least eight weeks after their return. Male travellers who are sexual partners of pregnant women should adopt these precautions throughout the women’s pregnancy. People diagnosed with Zika should adopt safer sex practices or consider abstinence for at least 6 months. Travellers who have returned to Singapore from affected areas should monitor their health for the next 14 days and consult a doctor if they have symptoms of Zika, such as fever, skin rashes, joint and muscle pains, headaches and red eyes. They should inform the doctor of the areas that they have travelled to.
