Air disinfection in measles transmission hotspots.

The average infection rate was 53-6% among more resistant, older children (grades 5-12) in classrooms without GUV air disinfection, compared with the average infection rate of 13-3% among more susceptible, younger children (grades K-4) in classrooms with GUV air disinfection (appendix). However, when GUV air disinfection was distributed to schools in rural upstate New York, NY, USA and in urban London, UK there was no protective effect.[[2]] In both locations GUV air disinfection was installed in classrooms and common areas, but unlike in suburban Philadelphia, children rode home on school buses in rural upstate New York and played together in crowded tenements in urban London. Properly applied, upper-room GUV air disinfection can safely and effectively reduce measles transmission in high-risk settings as herd immunity is re-established. [Extracted from the article]
