The burden of disease is significant, causing significant morbidity, especially in areas where hygiene is poor and access to clean water and sanitation is limited.

The populations most at risk are young children and people living in poverty, in rural areas of developing countries, especially in sub-Saharan Africa and Southeast Asia.

Explanation for step 1

Ascaris lumbricoides is a roundworm that causes a type of intestinal parasitic infection. This infection has a significant impact on the health of people, especially in areas with poor hygiene and limited access to clean water and sanitation. Children and people living in poverty in rural areas of developing countries are most at risk.

Step 2/4

Ascariasis is transmitted through the ingestion of contaminated food or water that contains infective eggs.

In the human host, the eggs hatch into larvae, which then mature into adult worms in the small intestine.

The adult worms can reach lengths of up to 40 cm and can cause abdominal pain, nausea, vomiting, diarrhea, and malnutrition.

The worms can also cause more severe complications such as intestinal blockage, appendicitis, and even peritonitis.

Explanation for step 2

The mode of transmission of ascariasis is through the ingestion of contaminated food or water that contains infective eggs. The adult worms that develop in the human intestine can cause abdominal pain, nausea, vomiting, diarrhea, and malnutrition. They can also lead to more serious complications.

Step 3/4

The transmission cycle of Ascaris lumbricoides starts with the ingestion of infective eggs from contaminated food or water.

The eggs hatch into larvae in the small intestine, which then mature into adult worms.

The adult worms lay eggs, which are then expelled from the host in the feces.

If the eggs are deposited in a suitable environment (warm and moist), they will develop into infective larvae that can then infect new hosts.
