Zika virus in Thailand

04 Jan 2024

Zika virus continues to be transmitted across Thailand. From the beginning of 2023 to 15 December, 722 Zika virus cases were reported in Thailand. Cases have been reported across 36 provinces, with the Central and Northern regions most affected.

On 4 January 2024, media reported 25 cases of Zika virus disease in the beach resort of Hua Hin, 200km south west of Bangkok.

Zika virus infection is caused by Zika virus (ZIKV). It is spread by mosquito bites and in pregnancy may result in severe consequences for the baby.

Advice to travellers

The type of mosquitoes which transmit ZIKV, are particularly persistent and aggressive biters.  They bite during the day between dawn and dusk.   If you are travelling to a country that has reported ZIKV infection, you must consider:

  • avoiding mosquito bites, especially if you are pregnant or planning pregnancy 
  • using condoms and contraception if you are sexually active during travel, and on your return home for 2 months (if you are female) or 3 months (if you are male): this is to avoid sexual transmission of ZIKV and the risk of ZIKV in pregnancy
  • travel insurance: if you are pregnant, check with your travel insurance company that you (and your baby) are covered under the policy before booking your trip, and be aware that the risk of ZIKV in any country may change during the time between planning your trip and travelling
  • checking the 'Alerts' section of the country page for your destination to see if there are any additional travel recommendations specifically for pregnant travellers, those who are planning pregnancy and for preventing onward sexual transmission
