A look at some of the measures announced:
MALAYSIA
Health authorities have asked travelers from South and Central America who display symptoms such as fever and rashes to immediately report to health centers.
Deputy Health Director Dr. Lokman Hakim Sulaiman said the move was imperative as it was not practical to conduct public health screenings at national gateways.
"The virus is difficult to detect and there is no quick point-of-care test which can be used," he said.
JAPAN
Japan's Foreign Ministry has issued a safety advisory urging women to try to avoid traveling to Brazil and other affected countries during pregnancy, and advised all travelers to the area to use caution. It suggested wearing long sleeves and pants, using mosquito sprays and avoid leaving out buckets, empty gardening pots and other containers that can catch water, and report to medical institutions in case of developing suspected symptoms.
The health authorities asked medical facilities to advise pregnant women not to visit the Zika areas, conduct test on suspected patients returning from the areas and send samples to the national lab.
AUSTRALIA
The Department of Foreign Affairs and Trade is advising pregnant women to avoid travel in areas where Zika is active.
The federal government is also asking Australian doctors to look out for signs of Zika infection in travelers returning from affected areas. A spokeswoman said Australian laboratories could diagnose the virus if required.
INDIA
Health Minister Shri J. P. Naddahas has stressed the control of the spread of Aedes mosquitoes that transmit dengue and the Zika virus and breed in clean water.
"Community awareness plays an instrumental role in this regard. There is a need for greater awareness amongst community," he said.
India is also stepping up surveillance and has set up a technical group to monitor the situation.
HONG KONG
Health officials are advising pregnant women and those planning pregnancy to adopt necessary anti-mosquito precautions, and consider deferring trips to areas with Zika virus transmissions.
Secretary for Food and Health Dr. Ko Wing-man also said that because only up to one quarter of the infected persons might develop relatively mild illness, "the attention was therefore not too big."
Aedes mosquitoes are currently not found in Hong Kong, the Health Department said, but the secretary said that other species of mosquito present in the territory are also considered as possible carriers of the disease.
VIETNAM
The Vietnamese health authority has warned people coming from countries with the Zika virus to monitor their health for 14 days and if they develop fever to report to medical facilities.
The health authority also warned people to empty water containers and use mosquito nets to prevent the possible spread of the virus.
