FRIDAY, Aug. 12, 2016 (HealthDay News) — Concerns around the mosquito-borne Zika virus aren't dampening many Americans' plans to visit Florida, a new survey shows.

Earlier this month, the first cases of locally acquired Zika infection were confirmed in the Miami-area Wynwood neighborhood. The virus can cause a transitory illness but is most dangerous to pregnant women, since maternal infection can trigger a serious birth defect called microcephaly. Babies with microcephaly are born with too-small heads and underdeveloped brains.

The new survey was conducted three days after the first 15 non-travel-related cases of Zika were reported in the Miami area. That has now increased to 25 cases, according to Florida health officials.

In their poll, researchers at the University of Florida questioned 828 people nationwide. All had already planned to visit the state within the next six months.

Most of the would-be visitors to Florida seem undeterred by the Zika news. More than 70 percent of those surveyed said they were concerned about the virus, but less than 10 percent of those with concerns changed their travel plans, according to researchers at the university's Tourism Crisis Management Initiative (TCMI).

Of the 10 percent of respondents who said they were changing their travel plans, 60 percent said they would postpone their visit to Florida, while 25 percent said they would travel somewhere else.

Among those who changed their plans, about 15 percent consulted with a health care provider before making that decision, the researchers noted.

The survey also found that 45 percent of respondents had "medium to high" levels of knowledge about Zika, and 82 percent knew about protective measures such as use of insect repellents, staying indoors with air conditioning, and having screened windows and doors.

There are steps that Florida officials can take to encourage visitors and keep them safe, stressed study lead author Ignatius Cahyanto in a University of Florida news release.

"Making insect repellent available for guests in public areas of hotels and other public accommodations, as well as directing them to information such as the Centers for Disease Control and Prevention [CDC] website, would help to build protective behaviors," said Cahyanto, an affiliate TCMI researcher from Black Hills State University in Spearfish, S.D.
