Cristian Molina, 26, sits on a bus while traveling to visit his family in Buenos Aires, Argentina, August 17, 2019. Molina contracted tuberculosis earlier this year. He lives in the shantytown of Lujan and shares living spaces with his parents, six siblings and four nephews. Doctors think one brother contracted the disease in prison before spreading it around the family when he returned home. REUTERS/Magali Druscovich SEARCH "ARGENTINA TB" FOR THIS STORY.
