Will your body actively try to kill a roundworm?

Yes, the immune system will recognize roundworms as foreign invaders and will attempt to kill or expel them from the body. The immune response may include inflammation, the release of enzymes and antibodies, and the activation of white blood cells to attack and destroy the roundworms. In some cases, medication may be needed to help the body effectively eliminate the roundworm infection.

Will a fever occur from just a single roundworm?

It is unlikely for a fever to occur as a direct result of a single roundworm infection. A fever is typically a response of the body's immune system to an infection, but it is more commonly associated with bacterial or viral infections rather than parasitic infections like roundworms. However, a person with a roundworm infection may experience other symptoms such as abdominal pain, diarrhea, weight loss, fatigue, and nutritional deficiencies, depending on the type and severity of the infection. If you suspect you have a roundworm infection or are experiencing any concerning symptoms, it is essential to seek medical attention for proper diagnosis and treatment.
