If you suspect that a person has worms, it is important to get them checked by a doctor to confirm the diagnosis and start treatment. The doctor will likely ask about the person's symptoms and do an examination of their skin, hair, and nails. They may also order tests to check for infection, such as a stool sample or a blood test.
A stool sample can show the presence of eggs or larvae in the feces, which can be indicative of an infection with certain types of worms. The doctor may also order a blood test to check for antibodies, which can show if the body is fighting off a worm infection. In some cases, the doctor may recommend imaging tests, such as an X-ray or CT scan, to look for evidence of an infection.
If a person has a confirmed case of worms, they will need to be treated with medication. The medication will depend on the type of worm and the severity of the infection. Treatment may include anti-parasitic medications, antibiotics, or other medications to help reduce symptoms. It is important to take all medications as prescribed and to finish the entire course of treatment to ensure the infection is completely eliminated.
