Occurence: Functionally eradicated (Only 0.00001181% of Inkopolitians, or 65 Inkopolitians, have the Bluering disease, according to recent reports)
Transmissibility: Direct contact with the parasite, ingestion of infected matter
Most vulnerable group: Pre-pubescent children, farmers, sewer workers
Pathogen: Parasite (Parasitic worm)
Treatment: Worm-eradicating medicine, surgery
Prevention: Public cleaning campaigns, awareness programs, decontamination of water, mass-droppings of chemicals that eradicate the parasite (But posses no threat to other living organisms)
About: The bluering disease, officially known as Devoratritergum, is a disease caused by a parasitic worm of the same name. The disease is functionally eradicated, as stated so by the Inkopolitian Health and Disease Control (IHDC) according to the 2042 IHDC Annual Report of Pathogens and Diseases (ARPD), the Bluering disease has been declared functionally extinct, as of today, only 65 Inkopolitians (61 Inklings, 4 Octolings) have the Bluering disease.
The disease is transmitted in two main ways: The most common method of transmission (It being still the most common method of transition, even during the disease's peak in 1906, when it infected around 700,000 Inkopolitians per year and killed around 650,000 per year) is through direct ingestion of infected matter, be it foodstuffs or liquid. The other method is considerably rarer, although counts for 12% of all Bluering cases, is the direct contact of the parasitic worm with the skin. The worm bites through the skin, with the host not realizing in most cases, due to the worm's anaesthetic saliva.
The so-called end-phase, or semi-terminal phase of the virus, is where the worm has managed to make holes in the Inkling skin that are surrounded by blue-like goo, (Hence the name "Bluering") a reaction of the saliva and the chemicals of the skin meeting. The worm can also dig holes through the Inkling hearts, although fairly rare, results in instant death. The worm can grow to sizes of up to 12 cm.
