Research led by the University of Otago in New Zealand has uncovered the strongest evidence yet that household overcrowding is a major risk factor for acute rheumatic fever and streptococcal infections of the skin.
Their research is published in two companion articles in the international medical journal The Lancet Regional Health — Western Pacific.
Lead researcher Professor Michael Baker of the University of Otago, Wellington, says it is the first time researchers have investigated risk factors for Group A streptococcal infections of the throat (strep throat) and skin (strep skin) that can cause rheumatic fever.
