Here's a basic list of all the parasites. Some are common in the area you live in, while others are rare or only found in certain parts of the world. All of these parasites are often called "parasites". In general, a parasite is anything that has to do with parasites (parasites are the result of some other living thing or body part being invaded by a parasite, as explained on the next page). There are many other terms, such as "spore", "myxomatosis", "zoonosis", and many more, to make it easier for you to understand what you are talking about. There is some variation in the definition of a parasite. I have also tried to include as many species as possible. This is only for reference. Many other types of parasitic diseases are discussed in the pages on parasitic diseases. Parasitic Diseases In some instances, you can get certain diseases from an infected person (or sometimes, even from a human that has the disease). This means that some of the symptoms listed in the table above are caused by the parasites. For example, people may have flu and the flu virus is known to be infectious. The flu can cause fever, rash, muscle aches, and fatigue. Many people are infected by the flu virus and don't feel ill.
