Dracunculiasis
Dracunculiasis, also called Guinea-worm disease, is a parasitic infection by the Guinea worm ('' Dracunculus medinensis).'' A person becomes infected by drinking water contaminated with Guinea-worm larvae that reside inside copepods (a type of small crustacean). Stomach acid digests the copepod and releases the Guinea worm larva, which penetrates the digestive tract and escapes into the body. Around a year later, the adult female worm migrates to an exit site usually the lower leg and induces an intensely painful blister on the skin. Eventually, the blister bursts, creating a painful wound from which the worm gradually emerges over several weeks. The wound remains painful throughout the worm's emergence, disabling the affected person for the three to ten weeks it takes the worm to emerge. The female worm releases larvae when the host submerges the wound in water in attempts to relieve the pain, thus continuing the life cycle. There is no medication to treat or prevent dra ...

Eradication Of Dracunculiasis
Eradication of dracunculiasis is an ongoing program. Dracunculiasis, or Guinea worm disease, is an infection by the Guinea worm that causes severe pain and open wounds when guinea worms exit the body through the skin. In 1986, there were an estimated 3.5 million cases of Guinea worm in 20 endemic nations in Asia and Africa. The number of human cases has since been reduced by more than 99.999%, to the range of 13–15 per year in 2021–2024, with only six countries remaining to be certified free of transmission: Chad, South Sudan, Mali, Ethiopia, Angola, and Sudan. Of these, only Chad and South Sudan have had human cases reported since the end of 2023. Cameroon has also had some cases in recent years, primarily due to its proximity to Chad, but was previously certified free of internal transmission. The campaign has been spearheaded by the Carter Center and other members of the London Declaration on Neglected Tropical Diseases, with former U.S. president Jimmy Carter as part of ...

Dracunculus Medinensis
''Dracunculus medinensis'' (Guinea worm, dragon worm, fiery serpent) is a nematode that causes dracunculiasis, also known as Guinea worm disease. The disease is caused by the female which, at around in length, is among the longest nematodes infecting humans. The length of specimens exhibits extreme sexual dimorphism, as the longest recorded male Guinea worm is only . Guinea worm disease is on target to be the second infectious disease of humans to be eradicated, after smallpox, and the ''D. medinensis'' species would be made extinct to accomplish it. It was formerly endemic to a wide swath of Africa and Eurasia; as of 2023, it remains endemic in five countries: Chad, Mali, South Sudan, Angola and Ethiopia, with most cases in Chad. Guinea worm spread to Angola , and it is now considered endemic there. Infection of domestic dogs is a serious complication in Chad. The common name "Guinea worm" is derived from the Guinea region of Western Africa. History ''Dracunculus m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copepod
Copepods (; meaning 'oar-feet') are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (living in the water column), some are benthos, benthic (living on the sediments), several species have Parasitism, parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, puddles, damp moss, or water-filled recesses of plants (phytotelmata) such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infectious Disease (medical Specialty)
Infectious diseases (ID), also known as infectiology, is a medical specialty dealing with the diagnosis and treatment of infections. An infectious diseases specialist's practice consists of managing nosocomial (Hospital-acquired infection, healthcare-acquired) infections or community-acquired infections. An ID specialist investigates and determines the cause of a disease (bacteria, virus, parasite, fungus or prions). Once the cause is known, an ID specialist can then run various tests to determine the best drug to treat the disease. While infectious diseases have always been around, the infectious disease specialty did not exist until the late 1900s after scientists and physicians in the 19th century paved the way with research on the sources of infectious disease and the development of vaccines. Scope Infectious diseases specialists typically serve as consultants to other physicians in cases of complex infections, and often manage patients with HIV/AIDS and other forms of immuno ...

Landlocked Developing Countries
The landlocked developing countries (LLDC) are developing country, developing countries that are landlocked country, landlocked. Due to the economic and other disadvantages suffered by such countries, the majority of landlocked countries are least developed countries (LDCs), with inhabitants of these countries occupying the bottom billion tier of the world's population in terms of poverty. Outside of Europe, there is not a single highly developed landlocked country as measured by the Human Development Index (HDI), and nine of the twelve countries with the lowest HDI scores are landlocked. Landlocked European countries are exceptions in terms of development outcomes due to their close integration with the regional European market. Landlocked countries that rely on transoceanic trade usually suffer a cost of trade that is double that of their maritime neighbours.Hagen. 2003, p. 13. Landlocked countries experience economic growth 6% less than non-landlocked countries, holding other vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eradication Of Smallpox
Smallpox was an infectious disease caused by Variola virus (often called Smallpox virus), which belongs to the genus '' Orthopoxvirus''. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was transmitted from one person to another primarily through prolonged face-to-face contact with an infected person or rarely via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medications could potentially ...

Endemic (epidemiology)
In epidemiology, an infection is said to be endemic in a specific population or populated place when that infection is constantly present, or maintained at a baseline level, without extra infections being brought into the group as a result of travel or similar means. The term describes the distribution of an infectious disease among a group of people or within a populated area. An endemic disease always has a steady, predictable number of people getting sick, but that number can be high ('' hyperendemic'') or low (''hypoendemic''), and the disease can be severe or mild. Also, a disease that is usually endemic can become epidemic. For example, chickenpox is endemic in the United Kingdom, but malaria is not. Every year, there are a few cases of malaria reported in the UK, but these do not lead to sustained transmission in the population due to the lack of a suitable vector (mosquitoes of the genus '' Anopheles''). Consequently, there is no constant baseline level of malaria inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
