The Centre for Health Protection is monitoring the Zika situation in Thailand and Malaysia.
Thai health authorities recorded 23 cases in the past week in Bangkok, Nong Khai, Chanthaburi, Phetchabun, Nakhon Ratchasima and Lopburi, bringing the country's total cases to 279 this year.
Malaysian authorities recorded six cases from September 1 to 13.
The centre is liaising with the World Health Organisation and with overseas, neighbouring and Mainland health authorities over the issue.
The centre urged the public to adopt strict anti-mosquito measures during travel. Pregnant women and those planning pregnancy should avoid travel to affected areas.
