Understanding Ascariasis and Its Prevention
Know about ascariasis, what it is, how it spreads, risks, diagnosis and treatment options. Learn how to prevent ascariasis.
Introduction
Ascariasis is a common parasitic infection caused by roundworms (Ascaris lumbricoides). While it might sound alarming, understanding the condition, its symptoms, and prevention methods can help you stay safe and healthy. This article will guide you through everything you need to know about ascariasis in simple, easy-to-understand terms.
What Is Ascariasis?
Ascariasis is an intestinal infection caused by parasitic roundworms. These worms live in the small intestine and can grow up to 15-35 cm in length. The infection spreads through contaminated food, water, or soil containing worm eggs. While ascariasis is more common in areas with poor sanitation, it can affect anyone exposed to unclean environments.

How Does Ascariasis Spread?
The infection spreads when:
- People consume food or water contaminated with worm eggs.
- Hands contaminated with infected soil touch the mouth.
- Children play in contaminated soil and put their hands in their mouths.
Once inside the body, the eggs hatch in the intestines, and the larvae travel through the bloodstream to the lungs. From there, they move up to the throat, are swallowed again, and mature into adult worms in the intestines.
Symptoms of Ascariasis
Many people with mild infections may not show symptoms. However, in moderate to severe cases, symptoms may include:
Early Stage (Lung Migration)
- Coughing or wheezing
- Shortness of breath
- Fever
Intestinal Stage (Adult Worms)
- Abdominal pain or discomfort
- Nausea or vomiting
- Diarrhoea or bloody stools
- Visible worms in stool
- Weight loss or malnutrition (especially in children)
In rare cases, a heavy worm infestation can lead to intestinal blockage, which requires immediate medical attention.
Who Is at Risk?
The categories which are included as risk are:
- Children: More likely to play in contaminated soil and put hands in their mouths.
- People in areas with poor sanitation: Lack of clean water and proper waste disposal increases risk.
- Farmers and gardeners: Frequent contact with soil may lead to exposure.
How Is Ascariasis Diagnosed?
If you suspect an infection, consult a doctor. Diagnosis usually involves:
- Stool test: To check for worm eggs.
- Blood tests: To detect signs of infection.
- Imaging tests (X-ray/ultrasound): In severe cases, to locate worms in the intestines or other organs.
Treatment Options
Ascariasis is treatable with antiparasitic medications, such as:
- Albendazole
- Mebendazole
- Pyrantel pamoate
These medications are highly effective and usually require just one or two doses. Severe cases with complications may need additional medical care.
Prevention Tips
The best way to avoid ascariasis is through good hygiene and sanitation practices:
1. Wash Hands Properly
Always wash your hands with soap and clean water:
- Before eating or preparing food.
- After using the toilet.
- After gardening or handling soil.
2. Drink Safe Water
- Use boiled, filtered, or bottled water in areas with poor sanitation.
3. Wash Fruits and Vegetables
- Thoroughly rinse raw produce before eating.
4. Avoid Walking Barefoot in Contaminated Soil
- Wear shoes in areas where soil may be infected.
5. Improve Sanitation
- Use proper toilets to prevent soil contamination.
- Ensure sewage is disposed of safely.
6. Educate Children
- Teach kids about handwashing and avoiding dirt-to-mouth contact.
When to See a Doctor
Consult a healthcare provider if you or your child experiences:
- Persistent stomach pain or vomiting.
- Worms in stool.
- Unexplained weight loss or malnutrition.
Early treatment prevents complications and helps in quick recovery.
Can Ascariasis Be Serious?
Most cases are mild, but complications can occur, such as:
- Intestinal blockage – Due to a large number of worms.
- Malnutrition – Worms absorb nutrients, leading to deficiencies.
- Bile duct or pancreatic duct obstruction – Rare but serious.
Final Thoughts
Ascariasis is preventable with good hygiene and sanitation. Simple habits like handwashing, drinking clean water, and proper food handling can protect you and your family. If you suspect an infection, seek medical advice promptly for effective treatment.
