Community participation is crucial for successful malaria control.

Case Study: Schistosomiasis

Schistosomiasis is a parasitic disease caused by blood flukes of the genus Schistosoma.

The disease is also known as snail fever.

It is common in Nigeria, especially in places with poor sanitation.

Limited access to clean water increases the risk of infection.

Overview of Schistosomiasis in Nigeria

• Schistosomiasis is endemic in Nigeria.



• About 29 million people remain at risk of infection.



• The disease mainly affects rural and peri-urban areas with contaminated water bodies.



• Children are especially vulnerable due to frequent water contact.

Case Study of a Schistosomiasis Patient in Nigeria

A 10-year-old boy from a rural village in the Niger Delta presented symptoms.

He suffered from abdominal pain, bloody urine, and fatigue.

Investigation revealed he regularly swam in a river infested with Schistosoma parasites.

Tests of stool and urine samples confirmed Schistosoma eggs presence.

The diagnosis confirmed schistosomiasis infection.

Transmission, Symptoms, and Treatment of Schistosomiasis

• Transmission occurs when parasites enter the human body via the skin in freshwater.



• Symptoms include abdominal pain, bloody stool or urine, fatigue, and enlarged liver and spleen.



• Treatment involves praziquantel medication, which effectively kills the parasites.

Measures to Control Schistosomiasis in Nigeria

• The government performs mass drug administration in high-risk regions.



• Awareness programs educate communities about avoiding contaminated water.



• Efforts focus on improving clean water access and sanitation facilities in endemic areas.

Schistosomiasis remains a major public health issue in Nigeria.

However, continued prevention and treatment efforts can reduce the disease burden.

Case Study on Onchocerciasis

Onchocerciasis is commonly known as river blindness.

The disease is caused by the parasitic worm Onchocerca volvulus.

Transmission occurs through bites of infected black flies.

These black flies are primarily of the Simulium species.

Introduction to Onchocerciasis in Nigeria

Nigeria is one of the African countries affected by onchocerciasis.

Endemic regions are mostly found in the savannah areas.

The disease poses a significant public health challenge in these communities.

Presentation of a Specific Case Study on Onchocerciasis

A 45-year-old farmer from a remote northern Nigerian village sought medical help.

He suffered from severe itching, skin rashes, and visual impairment.

The symptoms had lasted for several years.

This condition affected his ability to perform work.

Symptoms, Diagnosis, and Treatment Options Explained

Doctors diagnosed the farmer with onchocerciasis based on symptoms and skin snip tests.

Ivermectin was prescribed as the drug of choice to treat this disease.

This medication effectively kills the parasite larvae, called microfilariae.

Regular ivermectin administration controls symptoms and stops disease progression.

However, ivermectin does not kill the adult worms.

Impact of Onchocerciasis on Affected Communities in Nigeria

The disease profoundly affects communities beyond physical symptoms.

It causes skin lesions, blindness, and social stigma for affected individuals.

This stigma leads to discrimination and isolation from social interactions.

Such exclusion hinders full participation in daily activities.

Vision loss severely impacts livelihoods, especially for farmers and visual-dependent workers.

Without proper treatment and community support, individuals experience declining quality of life.

The disease also imposes economic burdens due to reduced productivity.

Controlling onchocerciasis requires sustained public health efforts in Nigeria.

Effective diagnosis, treatment, and community interventions can reduce disease impact.

Healthcare providers, policymakers, and communities must collaborate closely.

Raising awareness and improving treatment access are essential strategies.

These actions will improve health outcomes and support affected individuals’ well-being.
