With all due respect think about this, I along with others come don't get sick and spend lots of money in the local economy thereby helping those on the island that are working everyday to support their families. If I lived in fear of what could happen I would never leave my house much less get on a plane to fly (plane could crash), rent a car to drive (people die daily in car wrecks), swim in the ocean (drowning- 320,000 deaths in 2016), walk under a coconut tree (150 deaths annually from falling coconuts), walk outside to get the mail or exercise (cardiac arrest). Reasonable precautions can and should be take to determine illness and then people can simply be smart about hygiene.
