Although dozens of people are may be suffering from the bacterial disease, officials have denied to call it an epidemic or a confirmed outbreak.

The disease is the result of contact with water that has been contaminated by animal urine. Puerto Rico averages 60 reported cases of leptospirosis each year. The 74 suspected cases have transpired since Hurricane Maria hit the island.

More than a third of the island remains without running water; some of those affected by leptospirosis fell ill after drinking local stream water.

According to the CDC, symptoms of leptospirosis are wide and varied but can include high fever, jaundice, red eyes and body pain. The CDC also states that some infected people may have no symptoms at all, a worrisome thought for those in Puerto Rico that have resorted to drinking contaminated water.

The time between a person’s exposure to contaminated water and becoming sick can range from two days to four weeks, leaving plenty of time for more cases to be reported over the next month or more.

The CDC states that leptospirosis can last for a few days or several months depending on treatment, yet people in Puerto Rico are dying from the infection. 

"While most patients have mild or self-limiting infection, some patients will develop severe infection and present with bleeding or hemorrhage, kidney failure, meningitis and hepatitis," said Dr. M. Rizwan Sohail, a professor of medicine in the Division of Infectious Diseases at the Mayo Clinic. "The death rate in patients who develop severe infection is between 5 and 15 percent."
