Wow! Tuberculosis is scary. Because TB is often lethal this is on the same level as the college meningitis outbreak a while back. Good thing the TB is latent (not actively symptomatic or contagious) still. TB can manifest from latent into pulmonary with no warning, and that is the stage it can kill. Because TB starts in the lungs, respiratory problems are a first sign of the bacterial infection. I just don't understand how almost half of all people tested at Longmont High School came up positive if the strain is not contagious yet. Questions to be answered soon I hope.
