They are working in lots of other locations besides just Mozambique. They are also good at sniffing out whether a sputum sample is positive for TB! Check out their website. I've been giving them money for several years now. They were featured in an article in the NYTimes (http://www.nytimes.com/2010/06/17/opinion/17kristof.html), a list of different ideas for Father's Day gifts. My dad got a kick out of it.
