In the United States, the most common foodborne parasites are protozoa such as Cryptosporidium spp., Giardia intestinalis, Cyclospora cayetanensis, and Toxoplasma gondii; roundworms such as Trichinella spp. and Anisakis spp.; and tapeworms such as Diphyllobothrium spp. and Taenia spp.
This category includes a wide range of communicable diseases, including sexually transmitted diseases including HIV/AIDS, tuberculosis, diarrheal diseases, some vaccine-preventable diseases such as measles, and diseases caused by tropical parasites such as malaria and hookworm.
Parasitic infections can be spread in a number of ways. For example, protozoa and helminths can be spread through contaminated water, food, waste, soil, and blood. Some can be passed through sexual contact. Some parasites are spread by insects that act as a vector, or carrier, of the disease.
Of all parasitic diseases, malaria causes the most deaths globally. Malaria kills more than 400,000 people each year, most of them young children in sub-Saharan Africa.
There are three main types of parasites that can affect humans: protozoa, helminths, and ectoparasites.
The flu, measles, HIV, strep throat, COVID-19 and salmonella are all examples of infectious diseases.
COVID-19 is a viral disease, just one of the four main types of infectious diseases. The others include bacterial, fungal, and parasitic—each different in how they spread and how they affect the body.
The diseases caused by these intestinal protozoan parasites are known as giardiasis, amoebiasis, cyclosporiasis, and cryptosporidiosis respectively, and they are associated with diarrhoea (8).
Nausea or vomiting. Gas or bloating. Dysentery (loose stools containing blood and mucus) Rash or itching around the rectum or vulva.
Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms. Although the worms that cause schistosomiasis are not found in the United States, people are infected worldwide. In terms of impact this disease is second only to malaria as the most devastating parasitic disease.
Trichomoniasis is the most common parasitic STI, though scabies, lice, and giardia are also common parasitic STIs.
Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 700 000 deaths annually. They can be caused by either parasites, bacteria or viruses. Malaria is a parasitic infection transmitted by Anopheline mosquitoes.
Parasites are living things that use other living things - like your body - for food and a place to live. You can get them from contaminated food or water, a bug bite, or sexual contact. Some parasitic diseases are easily treated and some are not.
Common sources of infection
Sources, e.g. airborne, blood borne, sexually transmitted, fecal, oral, environment, stagnant water, warm-water systems, animals.
Treatment will depend on the cause of the infection. This article will focus on the most common and deadly types of infection: bacterial, viral, fungal, and prion.
Rhabditiform larvae in the gut become infective filariform larvae that can penetrate either the intestinal mucosa or the skin of the perianal area, resulting in autoinfection.
Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable. In 2021, there were an estimated 247 million cases of malaria worldwide.
