Roughly one-third of the world's population has been infected with M. tuberculosis, with new infections occurring in about 1% of the population each year. However, most infections with M. tuberculosis do not cause TB disease, and 9095% of infections remain asymptomatic. In 2012, an estimated 8.6 million chronic cases were active. In 2010, 8.8 million new cases of TB were diagnosed, and 1.201.45 million deaths occurred, most of these occurring in developing countries. Of these 1.45 million deaths, about 0.35 million occur in those also infected with HIV.
What percentage of the world's total population gets infected with tuberculosis every year?

West is one of the best-selling artists of all time, having sold more than 32 million albums and 100 million digital downloads worldwide. He has won a total of 21 Grammy Awards, making him one of the most awarded artists of all time and the most Grammy-awarded artist of his age. Three of his albums rank on Rolling Stone's 2012 "500 Greatest Albums of All Time" list; two of his albums feature at first and eighth, respectively, in Pitchfork Media's The 100 Best Albums of 20102014. He has also been included in a number of Forbes annual lists. Time named him one of the 100 most influential people in the world in 2005 and 2015.

By the late 1990s, blue LEDs became widely available. They have an active region consisting of one or more InGaN quantum wells sandwiched between thicker layers of GaN, called cladding layers. By varying the relative In/Ga fraction in the InGaN quantum wells, the light emission can in theory be varied from violet to amber. Aluminium gallium nitride (AlGaN) of varying Al/Ga fraction can be used to manufacture the cladding and quantum well layers for ultraviolet LEDs, but these devices have not yet reached the level of efficiency and technological maturity of InGaN/GaN blue/green devices. If un-alloyed GaN is used in this case to form the active quantum well layers, the device will emit near-ultraviolet light with a peak wavelength centred around 365 nm. Green LEDs manufactured from the InGaN/GaN system are far more efficient and brighter than green LEDs produced with non-nitride material systems, but practical devices still exhibit efficiency too low for high-brightness applications.[citation needed]
