In recognition of World TB Day, The Lancet published Tuberculosis 2014, a series featuring papers from The Lancet Infectious Diseases and The Lancet Respiratory Medicine “discussing topics ranging from host-directed therapies and vaccines, extremely drug-resistant tuberculosis, and new anti-tuberculosis drugs, [and] highlighting not only past successes, but also the challenges that need to be met to win the battle against tuberculosis” (3/24).
