>> 26 more Zika infections confirmed in Singapore, bringing the total to 82 by Wednesday morning. That sparked a travel warning from the United States, the latest country telling pregnant women or those trying to conceive to stay away. The government is urging locals to protect themselves, one online retailer saying sales of mosquito repellant have jumped five times higher in the past few days.
Still, at least five of the new infections seem to be from outside the area where Singapore's first cases were identified. Authorities have inspected thousands of homes across the city, spraying them with insecticide. But they expect more cases in the days to come. Neighbors Malaysia and Indonesia have set up thermal scanners at airports to try and track Zika cases from Singapore.
But they're designed to identify fevers, and 80% of Zika cases don't show symptoms. More than 55 million people pass through Singapore's main airport every year.
