What is going on in the Dominican Republic?

Six American tourists have died recently while vacationing in the Dominican Republic. Most of the deaths are “mysterious”, some involving pulmonary and cardiac issues, including a couple who were found dead in their hotel room with fluid in their longs. There have been a number of reports of people suddenly becoming sick while in hotels there, thankfully most don’t die. But the few that have have all died around the same time and the stories are getting a lot of attention.
