[Burness Communications] It is interesting to see, from my vantage point in South Africa, the reaction to the slight rise in tuberculosis (TB) cases in the U.S. Overall, TB in the U.S. has declined steadily since the early 1950s. But in the past few years, TB incidence has started to slowly increase. While the percentages seem steep, the overall increase is less than 1,300 new cases .
