The increased incidence of IBD since World War 2 has been correlated to the increase in meat consumption worldwide, supporting the claim that animal protein intake is associated with IBD. However, there are many environmental risk factors that have been linked to the increased and decreased risk of IBD, such as smoking, air pollution and greenspace, urbanization and Westernization. Inflammatory bowel diseases are increasing in Europe. Incidence and prevalence of IBD has risen steadily for the last decades in Asia, which could be related changes in diet and other environmental factors.Around 0.8% of people in the UK have IBD. Similarly, around 270,000 (0.7%) of people in Canada have IBD, with that number expected to rise to 400,000 (1%) by 2030. Research
The following treatment strategies are not used routinely, but appear promising in some forms of inflammatory bowel disease. Initial reports suggest that "helminthic therapy" may not only prevent but even control IBD: a drink with roughly 2,500 ova of the Trichuris suis helminth taken twice monthly decreased symptoms markedly in many patients. It is even speculated that an effective "immunization" procedure could be developed—by ingesting the cocktail at an early age.Prebiotics and probiotics are focusing increasing interest as treatments for IBD. Currently, there is evidence to support the use of certain probiotics in addition to standard treatments in people with ulcerative colitis but there is no sufficient data to recommend probiotics in people with Crohns disease. Both single strain and multi-strain probiotics have been researched for mild to moderate cases of ulcerative colitis.
An exanthem is a widespread rash occurring on the outside of the body and usually occurring in children. An exanthem can be caused by toxins, drugs, or microorganisms, or can result from autoimmune disease. The term exanthem is from the Greek ἐξάνθημα, exánthēma, a breaking out. It can be contrasted with enanthems which occur inside the body, such as on mucous membranes. Infectious exanthem
In 1905, the Russian-French physician Léon Cheinisse (1871–1924), proposed a numbered classification of the six most common childhood exanthems.Of these six "classical" infectious childhood exanthems, four are viral. Numbers were provided in 1905.The four viral exanthema have much in common, and are often studied together as a class. They are:

Scarlet fever, or "second disease", is associated with the bacterium Streptococcus pyogenes. Fourth disease, also known as "Dukes disease" is a condition whose existence is not widely accepted today. It was described in 1900 and is postulated to be related to the bacterium Staphylococcus aureus.In 1979 and 2001 a possible "seventh diease" was postulated following reports of a condition in Japan also referred to as acute febrile infantile mucocutaneous lymph node syndrome (MCLS).Many other common viruses apart from the ones mentioned above can also produce an exanthem as part of their presentation, though they are not considered part of the classic numbered list:

Varicella zoster virus (chickenpox or shingles)
Mumps
rhinovirus (the common cold)
unilateral laterothoracic exanthem of childhood
Some types of viral haemorrhagic fever are also known to produce a systemic rash of this kind during the progression of the disease.
