As tens of thousands of U.S. college students prepare for trips abroad for classes, volunteering or a vacation, they should start planning weeks in advance to make sure they get the shots and medications they need to avoid common illnesses, an NYU Winthrop Hospital travel expert told students Tuesday.

Dr. Theresa Fiorito, director of the hospital’s family travel clinic, told about a dozen students at the New York Institute of Technology in Old Westbury that when abroad in certain countries, simple steps such as not eating fruit that can’t be peeled or have thin skins, like apples, and not drinking beverages with ice — which can come from contaminated tap water — can prevent diarrhea. Between 30 and 70 percent of people traveling in developing countries get diarrhea, she said.

Most of Fiorito’s discussion Tuesday was focused on the illnesses you’re likely to contract in a developing country. You don’t have to worry about ice in your drink in France. But, she said, there are risks even in some developed counties.

The students at Tuesday’s presentation are in NYIT’s medical school, so they have more knowledge than most of the more than 325,000 U.S. college students who, according to the U.S. State Department, study abroad each year.

But Viraj Modi, 22, a first-year student who lives in Glen Cove, said he was surprised at the prevalence of hookworm. Fiorito displayed a photo of the infected foot of a friend of her brother, who contracted the parasite while walking barefoot on a beach in Puerto Rico.

“Walking on the beach and getting the worm is something I had in my mind, but I didn’t think it was all that common,” he said.

Up to 740 million people worldwide are infected with hookworm, according to the Centers for Disease Control and Prevention. Fiorito urged students to wear shoes if they walk on a beach.

Modi’s parents are Indian immigrants, and when he traveled with them to India four years ago for a wedding, he stayed healthy because, he said, his family followed basic precautions for traveling there, such as not eating food sold on the street and drinking only water from a bottle that is sealed.

The click of a sealed bottle being opened is important because, in some countries, water sold as purified is actually contaminated tap water that is placed into previously used water bottles, Fiorito said.

Avoiding contaminated water also means not brushing your teeth with tap water and not drinking smoothies or eating ice cream, she said.

Locals sometimes have remedies for illnesses, but they’re not always backed up by science. Some Peruvians swear by mate de coca — a tea made from the coca plant — to relieve the effects of altitude sickness, but there is no scientific data that shows it can prevent or treat it, Fiorito said. And because the coca plant is the source of cocaine, you will test positive for several days for cocaine.

Some travelers may take more risks than others, and even a traveler who rigorously follows rules on what is safe and not safe to eat or drink can get sick. For example, plates and pots and pans in restaurants may be washed in contaminated water, and even a relatively small amount of that water can get you sick, Fiorito said.

Lillian Butungi Niwagaba, director of NYIT’s Center for Global Health, said that’s why it’s important to pack recommended medications in advance.

“You have to be aware that some things you may do may make you sick,” Niwagaba said in an interview after the event. “But make sure you have the medicines [before you leave]. Some of these countries may not have the medicines you need.”


  • Before you go abroad, check this Centers for Disease Control and Prevention website, which has information on recommended vaccines and medications by country:
  • In most developing countries, don’t eat raw vegetables or fruits unless you can peel them. Don’t eat produce with thin skin, such as apples.
  • In restaurants, stick to fully cooked food served hot.
  • Avoid ice in most developing countries. Drink beverages only from sealed bottles.
  • Pack a travel health kit with prescriptions, first-aid supplies and other items.
  • Bring insect repellent with DEET, especially in tropical countries. Mosquito bites can lead to a number of diseases, including malaria, which in 2016 sickened about 216 million people and killed 445,000 worldwide, according to the CDC. Anti-malaria medications are available.
  • Contact a travel medicine specialist at least four to six weeks before departure.
