Deaths from<unk>  heart disease per million persons in 2012 Disability-adjusted life year for<unk>  heart disease per 100,000 inhabitants in 2004. About 33 million people are affected by<unk>  heart disease with an additional 47 million having asymptomatic damage to their heart valves. As of 2010 globally it resulted in 345,000 deaths, down from 463,000 in 1990. In Western countries,<unk>  has become fairly rare since the 1960s, probably due to the widespread use of antibiotics to treat streptococcus infections. While it has been far less common in the United States since the beginning of the 20th century, there have been a few outbreaks since the 1980s. The disease is most common among Indigenous Australians (particularly in central and northern Australia), Māori, and Pacific Islanders, and is also common in Sub-Saharan Africa, Latin America, the Indian Subcontinent, and North Africa.<unk>  primarily affects children between ages 5 and 17 years and occurs approximately 20 days after strep throat. In up to a third of cases, the underlying strep infection may not have caused any symptoms. The rate of development of<unk>  in individuals with untreated strep infection is estimated to be 3%. The incidence of recurrence with a subsequent untreated infection is substantially greater (about 50%). The rate of development is far lower in individuals who have received antibiotic treatment. Persons who have suffered a case of<unk>  have a tendency to develop flare-ups with repeated strep infections. The recurrence of<unk>  is relatively common in the absence of maintenance of low dose antibiotics, especially during the first three to five years after the first episode. Recurrent bouts of<unk>  can lead to valvular heart disease. Heart complications may be long-term and severe, particularly if valves are involved. In countries in Southeast-Asia, sub-Saharan Africa, and Oceania, the percentage of people with<unk>  heart disease detected by listening to the heart was 2.9 per 1000 children and by echocardiography it was 12.9 per 1000 children. Echocardiographic screening among children and timely initiation of secondary antibiotic prophylaxis in children with evidence of early stages of<unk>  heart disease may be effective to reduce the burden of<unk>  heart disease in endemic regions.
