It’s been more than a year since the Centers for Disease Control issued the first warning about travel to Brazil and the Caribbean because of the Zika virus. From January to August of last year, the virus dominated headlines and sent travel agents and hoteliers into a frenzy. Hotels in Zika zones like the St. Regis Puerto Rico saw business losses as great as 30 percent, while an unprecedented boom brought twice as many travelers to a flurry of resorts in Zika-free Hawaii.

But for the last few months, Zika has been out of sight and out of mind. Does that mean you should stop worrying about it? Here’s what the experts have to say.

■ The bad news: Zika was never eradicated from the 30 Caribbean islands and 18 countries in South America where it appeared last year, and the disease is now showing up everywhere from Southeast Asia to the South Pacific. But you haven’t been hearing about Zika lately because, for one, it’s winter, when mosquitoes don’t thrive. And the presidential election has dominated air waves since the Rio Olympics finished virus-free last August, leaving the story to simmer (very softly) on the back burner.

And yet, between the months of November and January, the CDC has logged almost 4,000 new cases of Zika in the United States, Puerto Rico, the US Virgin Islands, and American Samoa.

‘‘The disease as we understand it now is scarier than we originally thought,’’ said Kristin Lamoureux, associate dean of New York University’s Jonathan M. Tisch Center for Hospitality and Tourism. ‘‘It’s not quite the same as SARS or Ebola or other diseases that are contained geographically,’’ she explained, adding that other mosquito-borne diseases (like malaria or dengue fever) carry less stigma because they’re known to be curable. ‘‘We know we’re going to see Zika again in the spring,’’ she said.

■ The good news: Miami has served as a useful case study. When the city saw its first few cases of Zika transmission last summer, the local government acted quickly, enforcing a tripartite strategy of aerial spraying, manual spraying, and local awareness that eradicated the disease. ‘‘Miami Beach is a beacon of hope that Zika can be contained,’’ said Lamoureux, who added that other destinations can replicate the same model to contain outbreaks, or even prevent them, if they have the organizational means and resources to do so.

Other locales have managed to stay free of Zika altogether. Bermuda has never appeared on the CDC Travel Notice list, and neither have Uruguay, Chile, and Hawaii. And there’s compelling evidence that Puerto Rico has curtailed the number of cases dramatically.

Even better, according to former Food and Drug Administration chief and public health experts, nearly a dozen Zika vaccines are currently in trial phases, and at least one of them is entering early human studies.
