Rapid
A rapid is a section of a river where the river bed has a relatively steep gradient causing an increase in water velocity and turbulence. A rapid is a hydrological feature between a run and a cascade. A rapid is characterised by the river becoming shallower and having some rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white colour, forming what is called "whitewater". Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids are categorized in classes, generally running from I to VI. A Class 5 rapid may be categorized as Class 5.1-5.9. While class I rapids are easy to negotiate and require no maneuvering, class VI rapids pose threat to life with little or no chance for rescue.

The absolute reduction in mortality was small at 4 percent, but with 300,000 patients with HIV dying from TB in Africa every year, implementing this low-cost, rapid, bedside test could potentially save thousands of lives annually, the reduction in mortality is likely to be because urine testing, in conjunction with routine testing, resulted in a greater proportion of patients starting tuberculosis treatment early.
