That lingering stomach illness might be more than just a bug. Don't let an intestinal parasite disrupt your life. Understanding the signs of Cyclosporiasis is crucial for a swift diagnosis and recovery. Get the facts you need to protect your gut health.

What are the main causes of Cyclosporiasis?

This illness is caused by ingesting food or water contaminated with the microscopic Cyclospora parasite, often from an outbreak food source like fresh produce.
People get Cyclosporiasis by consuming fruits like berries or leafy greens that were grown or washed in contaminated water and served raw.
The infection is not typically contagious from person to person because the parasite needs time outside the body to become infectious.

Key symptoms of Cyclosporiasis to watch for

The most common Cyclosporiasis symptoms include watery diarrhea, loss of appetite, weight loss, cramping, bloating, and increased gas.
Sufferers often experience prolonged fatigue, nausea, and low-grade fever, with symptoms sometimes seeming to improve and then return again.
If left untreated, symptoms can last for weeks or months, potentially leading to long term effects like malabsorption and chronic fatigue.

How can you prevent Cyclosporiasis effectively?

The best prevention of Cyclosporiasis involves avoiding food and water that may be contaminated, especially when traveling to endemic regions.
Thoroughly wash all fresh fruits and vegetables with safe, clean water before eating them, though this may not entirely eliminate the risk.
If you develop symptoms, a proper diagnosis of Cyclosporiasis via a stool sample is needed to get the correct treatment and prevent complications.
