But parasites can be diagnosed by means of several stool examinations. A correct diagnosis is essential. For example, if roundworms and some other type of parasite are present, the roundworm needs to be treated first. Because some medicines do not kill the worms but may only irritate them, so that they migrate to other body organs and cause serious damage. While drug treatment has proved effective in getting rid of parasites, it is better to avoid being infected with them in the first place.
Cleanliness is the best protection.
Excrement should not be left exposed to the air. Toilet facilities should be a safe distance from the water source. Human waste should not be used as fertilizer. Proper hygiene is essential as well. In addition, don't let children eat dirt.
