What is preventive treatment for ascariasis

Condition analysis:
In developing countries, groups at higher risk for soil-transmitted helminth infections (hookworm, Ascaris, and whipworm) are often treated without a prior stool examination. Treating in this way is called preventive treatment (or "preventive chemotherapy"). The high-risk groups identified by the World Health Organization are preschool and school-age children, women of childbearing age (including pregnant women in the 2nd and 3rd trimesters and lactating women) and adults in occupations where there is a high risk of heavy infections. School-age children are often treated through school-health programs and preschool children and pregnant women at visits to health clinics.

Instructions:
What are the complications of ascariasis? Most cases of ascariasis are mild and don’t cause major problems. However, heavy infestations can spread to other parts of the body and lead to dangerous complications. They can include:

Intestinal blockage occurs when a mass of worms blocks your intestines causing severe pain and vomiting. Intestinal blockage is considered a medical emergency and requires treatment right away.

Duct blockages occur when the worms block the small passageways to your liver or pancreas.

Infections that lead to loss of appetite and poor absorption of nutrients puts children at risk of not getting enough nutrients, which can affect their growth.

Children are more likely to have gastrointestinal complications because their small intestines increase their chances of having an intestinal blockage.
