The dangerous resurgence of tuberculosis in China (post)
China now has the second largest tuberculosis epidemic -second only to India- with more than 1.3 million new cases of tuberculosis every year. What makes the situation particularly serious, however, is that, according to the Chinese Center for Disease Control, China has the largest number of patients with Multiple Drug Resistant Tuberculosis (MDR-TB), and that Extremely Resistant Drug Tuberculosis (XDR-TB) is also widespread. These facts show the need to step up efforts to combat the disease.
Deaths and infections from HIV, tuberculosis, and malaria plummet globally (post)
New HIV infections dropped by almost one-third from the epidemic peak; TB deaths declined by 3.7% between 2000 and 2013; child deaths from malaria in sub-Saharan Africa have dropped 31.5% in the past decade. Despite major progress, the quality of programs to treat HIV varies widely.
Tuberculosis in children: an interview with Dr Peter Dodd, University of Sheffield (post)

Cross-sectional studies of tuberculosis prevalence in Cambodia between 2002 and 2011 (post)
Tuberculosis remains a major global health problem, with 8.6 million estimated incident cases and 1.3 million estimated deaths in 2012. Cambodia ranks second among the 22 countries with a high tuberculosis burden. Since the World Health Organization (WHO) adopted the DOTS (directly observed treatment, short-course) strategy in 1994, which is based on the passive detection of cases of smear-positive tuberculosis, this policy has been the foundation of global tuberculosis control. Cambodia’s national tuberculosis control programme introduced DOTS in hospitals in 1994 and decentralized it to primary care health centres between 1999 and 2004 with the technical support of WHO and the Japan International Cooperation Agency.

New podcast discusses past, present, and future attempts to measure pediatric TB (post)
When a recent study in the Lancet revealed that there may be 650,000 annual cases of TB in children, some began to question whether these figures were at odds with the estimate of 530,000 previously made by WHO in 2012. In reality, WHO has been closely involved in much of the recent research that has emerged on the subject. Additionally, more research is expected and needed in order to even further define the pediatric TB landscape. This podcast features some of the leaders in pediatric TB research contextualizing past, present, and future research into the pediatric TB landscape.
