Rat lungworm disease is caused by the parasitic roundworm Angiostrongylus cantonensis, with the adult form of the parasite found only in rats. This page requires Javascript. African snails are, if anything, less likely to be agents of infection, since no one misses a hand-sized snail in their food. The economic and health effects of schistosomiasis are considerable and the disease disables more than it kills. Entire communities living in highly endemic areas. Credit: H. Zell, GNU Creative Commons via Wikimedia Commons, Credit: David Robinson, APHIS, NAS, USDA and Yuri Yashin,,, Credit: Rui Almeida, Creative Commons via Wikimedia Commons, Credit: Yuri Yashin,, The shell of the Giant African Land Snail is conical and narrow, with 7 to 9 spirals visible on its surface. Liver enlargement is common in advanced cases, and is frequently associated with an accumulation of fluid in the peritoneal cavity and hypertension of the abdominal blood vessels. If you handle snails or slugs, wear gloves and wash your hands. Destructive, disease-carrying devils are invading Florida at an alarming pace. The snails should not be handled without proper protection and sanitation. They may carry organisms that can cause diseases in humans. However, preventive chemotherapy for schistosomiasis, where people and communities are targeted for large-scale treatment, is only required in 52 endemic countries with moderate-to-high transmission. In children, schistosomiasis can cause anaemia, stunting and a reduced ability to learn, although the effects are usually reversible with treatment. WHO coordinates the strategy of preventive chemotherapy in consultation with collaborating centres and partners from academic and research institutions, the private sector, nongovernmental organizations, international development agencies, and other United Nations organizations. Achatina fulica is a species of large land snail that belongs in the family Achatinidae. Monitoring is essential to determine the impact of control interventions. Fibrosis of the bladder and ureter, and kidney damage are sometimes diagnosed in advanced cases. Cooperate with all quarantine restrictions or rules that might be imposed. Poor hygiene and play habits make children especially vulnerable to the infection. Working with partners and the private sector, WHO has advocated for increased access to praziquantel and resources for implementation. The giant African snail is currently found in Florida and Hawaii. This disease may also have other long-term irreversible consequences, including infertility. It is estimated that at least 90% of those requiring treatment for schistosomiasis live in the African Region. Fact Sheet on Rat Lungworm Parasite [ 167.3 kB ] (Florida Department of Health) Schistosomiasis, or bilharzia, is a disease that is caused by parasitic worms. Schistosomiasis control focuses on reducing disease through periodic, large-scale population treatment with praziquantel; a more comprehensive approach including potable water, adequate sanitation, and snail control would also reduce transmission. The eggs of intestinal schistosomiasis can be detected in faecal specimens through a technique using methylene blue-stained cellophane soaked in glycerine or glass slides, known as the Kato-Katz technique. People can get infected by eating raw or undercooked snails or slugs that are infected with this parasite. It has been found that the snails may cause brain diseases. The aim is to reduce disease morbidity and transmission: periodic treatment of at-risk populations will cure mild symptoms and prevent infected people from developing severe, late-stage chronic disease. People are infected during routine agricultural, domestic, occupational, and recreational activities, which expose them to infested water. There are 2 major forms of schistosomiasis – intestinal and urogenital – caused by 5 main species of blood fluke. An assessment of the status of transmission is being made in several countries. Migration to urban areas and population movements are introducing the disease to new areas. Chronic schistosomiasis may affect people’s ability to work and in some cases can result in death.1 The number of deaths due to schistosomiasis is difficult to estimate because of hidden pathologies such as liver and kidney failure and bladder cancer. The snail's range is limited by cold temperatures and moisture, as well as soil calcium needed for its shell. Estimates show that at least 218 million people required preventive treatment in 2015. The WHO strategy for schistosomiasis control focuses on reducing disease through periodic, targeted treatment with praziquantel through the large-scale treatment (preventive chemotherapy) of affected populations. The control of schistosomiasis is based on large-scale treatment of at-risk population groups, access to safe water, improved sanitation, hygiene education, and snail control. The classic sign of urogenital schistosomiasis is haematuria (blood in urine). Although medically diverse, neglected tropical diseases share features that allow them to persist in conditions of poverty, where they cluster and frequently overlap. The creatures abound at Parque Forestal, a … In some cultures, snails are commonly eaten. Under optimal conditions, some individuals may live as long as 9 years. Estimates show that at least 218 million people required preventive treatment for schistosomiasis in 2015. The urinary form of schistosomiasis is also associated with an increased risk for bladder cancer in adults. A significant amount of praziquantel, to treat more than 100 million children of the school age per year, has been pledged by the private sector and development partners. The frequency of treatment is determined by the prevalence of infection in school-age children. In children, it may cause poor growth and learning difficulty. Recently, 10 children affected with brain diseases in Ernakulam were found to have contracted it … An official website of the United States government It was reintroduced in 2011, and eradication efforts are currently underway. Over the past 10 years, there has been scale-up of treatment campaigns in a number of sub-Saharan countries, where most of those at risk live. Giant African snail eggs are about 5 mm across and are laid in huge masses. Urogenital schistosomiasis is also considered to be a risk factor for HIV infection, especially in women. Lack of hygiene and certain play habits of school-aged children such as swimming or fishing in infested water make them especially vulnerable to infection. Children with S. haematobium almost always have microscopic blood in their urine which can be detected by chemical reagent strips. Schistosomiasis, or bilharzia, is a disease that is caused by parasitic worms. The Giant African Snail (Lissachatina fulica or Drinking water can come from rivers, lakes and reservoirs and should be boiled for at least 1 minute to kill any parasites. Adults considered to be at risk in endemic areas, and people with occupations involving contact with infested water, such as fishermen, farmers, irrigation workers, and women whose domestic tasks bring them in contact with infested water. However, a major limitation to schistosomiasis control has been the limited availability of praziquantel.

Pest and Diseases Image Library, The giant African snail is an invasive alien species, which is a host for Anigiostrongylus cantonensis, the rat lungworm, which causes eosinophilic meningitis in human beings. Outbreaks of human angiostrongyliasis have involved a few to hundreds of persons; over 2,800 cases have been reported in the literature from approximately 30 countries. Schistosomiasis is the second most socioeconomically devastating parasitic disease after malaria. Giant African land snails pose a serious health risk to humans by carrying the parasite rat lungworm, known to cause meningitis in humans. Plant Industry. In urinary schistosomiasis, there is progressive damage to the bladder, ureters and kidneys. The golden or channelled apple snail: is a fresh water snail; it has a thin smooth shell; is 3-6 cm in height; shell colour varies from yellow-brown to greenish-brown or dark chestnut.
