Parasitic infections: Parasites are organisms that live inside other organism's bodies (hosts) for their survival. Some parasites do not cause any harm to their host, while some cause sickness in the human body, resulting in parasitic infection. There are three types of organisms responsible for causing a parasitic infection that include protozoa (single-celled and multiply inside the body), Helminths (multicelled, live outside the body like tapeworms), and Ectoparasites (multi-celled, live or feed off the skin like mites).
Bancroft's filariasis: It is caused by thread-like worms that live inside humans' lymphatic system. The lymphatic system of the body consists of fluid and is responsible for fighting infections. This disease spreads from one person to another by mosquitoes. Common symptoms include fever and skin exfoliation. And high levels of eosinophils (white blood cells).
Loiasis: It is also called an 'African eye worm,' an infectious parasitic disease transmitted to humans by the bite of Chrysops deerfly species. A person dealing with this disease may face itchy, non-painful swellings in their body. Sometimes, a person may see worms crawling under their skin or an eye worm.
River blindness: It is caused by a parasitic worm and is transmitted through repeated bites by black flies that live near rivers and streams. If not treated, then it may even cause visual impairment and sometimes blindness.
Eosinophilic lung: This is a disease related to lung problems in which white blood cells in the body increase. White blood cells are responsible for fighting allergic reactions and certain infections. Some of the symptoms of this disease include cough, chest pain, tightness, increased mucus, rapid breathing, bloody mucus and shortness of breath.
