Increasing outbreaks of the mosquito-borne Zika virus have prompted a plethora of travel advisories for visits across Asia, the Caribbean, North, Central and South America, and the Pacific Islands.
Countries differ on the risk posed by various destinations. For South-east Asia, the United States has issued a Zika travel warning only for Singapore, but Britain says Thailand is high-risk and the Philippines and Indonesia are a moderate risk. The European Centre for Disease Prevention and Control warns that travel to Thailand and Indonesia is risky, but omits the Philippines.
Travel advisories from governments and health organisations, however, are consistent in urging pregnant women and those planning to become pregnant to avoid non-essential travel to countries with Zika outbreaks.
The advisories also encourage travellers to use mosquito repellent and to wear protective clothing. Given the risk of sexual transmission of the virus, condoms and a period of abstinence from sex after returning from Zika hot spots are advised.
