Australia, South Korea and Taiwan have issued warnings advising pregnant women and women trying to get pregnant not to visit Singapore, where a Zika outbreak has left dozens infected, Reuters reports.

As of Tuesday afternoon local time, 56 people in Singapore had contracted Zika, a mosquito-borne illness that came to international attention last summer when it was linked to birth defects in Brazil. Singapore’s authorities say they are monitoring the situation but note that the maritime city-state remains a “safe travel destination.”

Singapore is considered one of the world’s most important travel hubs, but its tropical climate makes it an ideal breeding ground for mosquitoes.
