John, 3, who suffers from multi-drug-resistant tubeculosis (MDR-TB), is held by his mother Elizabeth, also an MDR-TB case, after she gave him his medication at a Medecins Sans Frontieres (MSF)-run clinic in Nairobi on March 24, 2015, World Tubeclosis Day. Globally, TB continues to kill 1.5 to 2 million people each year and remains the leading cause of death in people with HIV. In 2013, there were 90,000 new cases of TB diagnosed in Kenya and an estimated 20,000 cases went undetected. AFP PHOTO / TONY KARUMBA (Photo credit should read TONY KARUMBA/AFP/Getty Images)
