Zika Virus Update as of 30 May 2016 - No Zika Cases in Cayman Islands
- Since the Aedes aegypti mosquitoes (the primary vector for transmission) are day-biting mosquitoes, it is recommended that those who sleep during the daytime, particularly young children, the sick or elderly, should use insecticide-treated mosquito nets to provide protection. Mosquito coils or other insecticide vaporizers may also reduce the likelihood of being bitten.
- During outbreaks, space spraying of insecticides may be carried out periodically to kill flying mosquitoes. Suitable insecticides (recommended by the WHO Pesticide Evaluation Scheme) may also be used as larvicides to treat relatively large water containers.
- Basic precautions for protection from mosquito bites should be taken by people travelling to high risk areas, especially pregnant women. These include use of repellents, wearing light-coloured, long sleeved shirts and pants, and ensuring rooms are fitted with screens to prevent mosquitoes from entering.
- WHO does not recommend any travel or trade restriction to Puerto Rico based on the current information available.
