Worm Diseases
Soil-transmitted helminth infections
Soil-transmitted helminth infections are among the most common infections worldwide and affect the poorest and most deprived communities. They are transmitted by eggs present in human faeces which in turn contaminate soil in areas where sanitation is poor. The main species that infect people are the roundworm (Ascaris lumbricoides), the whipworm (Trichuris trichiura) and hookworms (Necator americanus and Ancylostoma duodenale).

Key facts
Soil-transmitted helminth infections are caused by different species of parasitic worms.

They are transmitted by eggs present in human faeces, which contaminate the soil in areas where sanitation is poor.

Approximately 1.5 billion people are infected with soil-transmitted helminths worldwide.

Infected children are nutritionally and physically impaired.

Control is based on:
periodical deworming to eliminate infecting worms
health education to prevent re-infection
improved sanitation to reduce soil contamination with infective eggs.
Safe and effective medicines are available to control infection.

Dracunculiasis (guinea-worm disease)

Key facts
Dracunculiasis is a crippling parasitic disease on the verge of eradication, only 25 human cases were reported in 2016.

The disease is usually transmitted when people who have little or no access to improved drinking water sources swallow stagnant water contaminated with parasite-infected water-fleas (Cyclops) that carry infective guinea-worm larvae.

Of the 20 countries that were endemic for the disease in the mid-1980s, only 3 countries reported cases in 2016 (Chad (16), South Sudan (6) and Ethiopia (3)).

From the time infection occurs, it takes between 10–14 months for the transmission cycle to complete until a mature worm emerges from the body.

Dracunculiasis (commonly known as guinea-worm disease) is a crippling parasitic disease caused by Dracunculus medinensis - a long, thread-like worm. It is transmitted exclusively when people drink stagnant water contaminated with parasite-infected water fleas.

Dracunculiasis is rarely fatal, but infected people become non-functional for weeks. It affects people in rural, deprived and isolated communities who depend mainly on open surface water sources such as ponds for drinking water.


We plan to do einterviews with MBBS doctors to understand 4 things
1) Tests or questions you ask in first few meetings
2) What it means in medical terms
3) What it means in non medical terms
4) What should the patient or care takers do

We might interview Aurvedic doctors, homeopathic doctors, Yoga teachers on this health issue
