A parasitic infection can be a serious, even life-threatening issue. A parasite is any organism that lives on or in another organism, feeding off its host to sustain itself. Parasites can sap energy and nutrients from the host, leaving behind waste products that are toxic, and sometimes deadly. Parasite symptoms, particularly for intestinal parasites, are broad and sometimes difficult to assess.
Parasites exist around around the world, but types of parasites vary by region. A parasite such as lung fluke may be more prevalent in Southeast Asia than in North America. With Parasites come parasitic diseases. They can range from relatively benign and innocuous, to irritating and uncomfortable, to fatal. These are some of those found here in Hong Kong.
