Parasites causing human diseases
Parasites causing human diseases is a vast topic within the field of biology and medical science. Below is a general overview of some important parasites and the diseases they cause:
- Malaria: Malaria is caused by the protozoan parasite of the genus Plasmodium. The most common species causing malaria in humans are Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale. Malaria is transmitted through the bite of infected female Anopheles mosquitoes. Symptoms include fever, chills, headache, muscle aches, and fatigue.
- Leishmaniasis: Leishmaniasis is caused by the protozoan parasite of the genus Leishmania. It is transmitted through the bite of infected sandflies. There are three main forms of leishmaniasis: cutaneous, mucocutaneous, and visceral. Cutaneous leishmaniasis results in skin sores, mucocutaneous affects the mucous membranes of the nose and throat, and visceral leishmaniasis affects the internal organs and can be fatal if left untreated.
- Trypanosomiasis (African sleeping sickness): Trypanosomiasis is caused by the protozoan parasite Trypanosoma brucei. It is transmitted to humans through the bite of infected tsetse flies. The disease occurs in two stages: the first stage involves fever, headache, and joint pain, while the second stage affects the central nervous system, leading to sleep disturbances, confusion, and neurological problems.
- Schistosomiasis (Bilharzia): Schistosomiasis is caused by parasitic flatworms of the genus Schistosoma. It is transmitted through contact with freshwater contaminated by the larvae of the parasite, which penetrate the skin of individuals. The disease affects various organs, including the intestines, liver, bladder, and blood vessels. Symptoms include abdominal pain, diarrhea, blood in urine, and liver and spleen enlargement.
- Guinea worm disease: Guinea worm disease is caused by the parasite Dracunculus medinensis. It is transmitted to humans through drinking water contaminated with the larvae of the parasite. The larvae mature into long, thread-like worms that emerge from painful skin blisters, usually in the lower limbs. The disease can cause debilitating pain and secondary bacterial infections.
- Taeniasis/Cysticercosis: Taeniasis is caused by the tapeworm Taenia solium, while cysticercosis is caused by the larval form of the same tapeworm. Taeniasis occurs when humans ingest undercooked pork containing the tapeworm larvae. Cysticercosis occurs when humans ingest the eggs of the tapeworm, usually through contaminated food or water. Symptoms of taeniasis may include abdominal pain, weight loss, and digestive disturbances. Cysticercosis can affect various organs, including the brain, leading to seizures, headaches, and neurological problems.
These are just a few examples of parasites causing human diseases. There are many other parasitic infections, each with its own unique characteristics and impact on human health.

Case Study on AIIMS-SYLLABUS Biology syllabus Parasites causing human diseases
Malaria – A Parasitic Disease
Introduction: Malaria is a parasitic disease caused by the protozoan parasite of the genus Plasmodium. It is one of the major global health concerns, particularly in tropical and subtropical regions. Malaria is transmitted through the bite of infected female Anopheles mosquitoes. The disease affects millions of people every year and is responsible for a significant number of deaths worldwide.
Clinical Presentation: A 28-year-old male presents to a rural health clinic in a malaria-endemic area with symptoms of high fever, chills, headache, muscle aches, and fatigue. The patient reports a history of traveling to a nearby forested area where he was exposed to mosquito bites. On examination, the patient has an elevated body temperature and shows signs of sweating. His spleen is enlarged, and he appears weak.
Diagnosis: Based on the clinical presentation and the endemicity of malaria in the area, the healthcare provider suspects malaria and orders laboratory tests. A blood sample is collected, and a rapid diagnostic test (RDT) is performed to detect the presence of Plasmodium antigens in the patient’s blood. The RDT confirms the diagnosis of malaria by detecting the specific Plasmodium species causing the infection.
Treatment: The patient is diagnosed with Plasmodium falciparum malaria, the most severe form of the disease. Immediate treatment is initiated with an appropriate antimalarial drug regimen, considering local drug resistance patterns. Artemisinin-based combination therapy (ACT) is the recommended treatment for uncomplicated falciparum malaria. The patient is given a full course of antimalarial medication and is advised to complete the treatment as prescribed.
Prevention and Control: In addition to prompt treatment, preventive measures are crucial in malaria control. The healthcare provider emphasizes the importance of personal protective measures, such as using insecticide-treated bed nets and wearing long-sleeved clothing, to prevent mosquito bites. Environmental interventions, including mosquito control programs and elimination of mosquito breeding sites, are also crucial in reducing the mosquito population and interrupting disease transmission.
Follow-up and Education: The patient is advised to return for follow-up visits to monitor his response to treatment and ensure complete recovery. During the follow-up visits, the healthcare provider educates the patient about malaria prevention, including the proper use of bed nets, indoor residual spraying, and seeking early diagnosis and treatment in case of fever. The patient is also informed about the potential complications of malaria, such as severe anemia, organ failure, and cerebral malaria, emphasizing the importance of seeking medical help promptly in case of worsening symptoms.
Conclusion: Malaria is a life-threatening parasitic disease caused by Plasmodium parasites. Prompt diagnosis, appropriate treatment with effective antimalarial drugs, and implementation of preventive measures are vital in controlling the disease. Awareness about malaria, its transmission, and prevention strategies is essential to reduce the burden of this parasitic infection and improve the health outcomes of individuals living in endemic areas.
