There have been 49 cases of cyclosporiasis in Suffolk County since the beginning of the year, Suffolk County health officials say. That is over double the 17 confirmed cases in Nassau County.

The Suffolk County Department of Health Services says they are monitoring an increase in cases alongside state and federal agencies.

The gastrointestinal-illness is known for causing overwhelming watery diarrhea that may last a month or longer, loss of appetite, stomach cramps, muscle aches, nausea, vomiting and fatigue.

Cyclosporiasis is typically contracted through contaminated food or water, with imported foods such as cilantro, basil, salad mixes, snow peas and raspberries to be cautious of.

People with weaker immune systems may be at risk for a more severe, prolonged illness.

The typical treatment for cyclosporiasis is antibiotics, and fluids to prevent dehydration.

"To prevent cyclosporiasis, the CDC recommends thoroughly washing your hands before and after preparing foods, thoroughly washing fruits and vegetables under running water. Cooking vegetables to temperatures of 158° F or higher is the most effective way to kill the parasite," said Suffolk County Department of Health Services Commissioner Dr. Gregson Pigott.
