Common human parasites

Parasites range from microscopic protozoa like Giardia and the organisms that cause malaria to worms like roundworms and tapeworms. Billions of people worldwide are affected by parasitic infections, especially where clean water and sanitation are limited. The relationship between humans and microbes is complex; not every organism we host is harmful.

Signs and prevention

Signs of a parasitic infection can include digestive problems, fatigue, weight loss, itching or rashes, but these symptoms have many causes, so testing by a healthcare provider is essential. Preventing parasite infections: wash hands, drink safe water, cook meat thoroughly, wash produce, and take precautions when traveling.

When to talk with a doctor

If you have symptoms that could be linked to a parasite, such as ongoing digestive trouble, unexplained weight loss, itching, or fatigue after travel, the most important step is to see a healthcare professional. Proper testing helps identify the cause, and many parasitic infections are treatable.
