including the difficulty of developing an effective vaccine, the expensive and time-consuming diagnostic process, the necessity of many months of treatment, the increase in HIV-associated tuberculosis, and the emergence of drug-resistant cases in the 1980s. In developed countries, tuberculosis is less common and is found mainly in urban areas. In Europe, deaths from TB fell from 500 out of 100,000 in 1850 to 50 out of 100,000 by 1950. Improvements in public health were reducing tuberculosis even before the arrival of antibiotics, although the disease remained a significant threat to public health, such that when the Medical Research Council was formed in Britain in 1913 its initial focus was tuberculosis research. In 2010, rates per 100,000 people in different areas of the world were: globally 178, Africa 332, the Americas 36, Eastern Mediterranean 173, Europe 63, Southeast Asia 278, and Western Pacific 139. Russia Russia has achieved particularly dramatic progress with a decline in its TB mortality rate—from 61.9 per 100,000 in 1965 to 2.7 per 100,000 in 1993; however, mortality rate increased to 24 per 100,000 in 2005 and then recoiled to 11 per 100,000 by 2015. China China has achieved particularly dramatic progress, with about an 80% reduction in its TB mortality rate between 1990 and 2010. The number of new cases has declined by 17% between 2004 and 2014. Africa In 2007, the country with the highest estimated incidence rate of TB was Eswatini, with 1,200 cases per 100,000 people. In 2017, the country with the highest estimated incidence rate as a % of the population was Lesotho, with 665 cases per 100,000 people. India As of 2017, India had the largest total incidence, with an estimated 2,740,000 cases. According to the World Health Organization (WHO), in 2000–2015, India's estimated mortality rate dropped from 55 to 36 per 100,000 population per year with estimated 480 thousand people died of TB in 2015. In India a major proportion of tuberculosis patients are being treated by private partners and private hospitals. Evidence indicates that the tuberculosis national survey does not represent the number of cases that are diagnosed and recorded by private clinics and hospitals in India. North America In the United States Native Americans have a fivefold greater mortality from TB, and racial and ethnic minorities accounted for 84% of all reported TB cases. In the United States, the overall tuberculosis case rate was 3 per 100,000 persons
