I just got Science News October 18, 2014 issue. Some interesting information, some way beyond my unpaid level however, but two that should be interesting to all South Dakotans and even a few SD scientists.
Get some data on the obesity epidemic. Move cursor over the state on the map to get the information.
South Dakota not the worst, and not the best either. The US obesity rate has gone from 15% in 1990 in Mississippi to 35.1% in 2013. Colorado started and ended better, but still sort of scary. The obesity rate in Colorado in 1990 was 6.9% and increased to 21.3% in 2013. And I just ate a couple handfuls of mixed nuts while reading the article and posting this.
For years, I have thought an experiment tracing "infection" rate from door handles, etc. in a day would be interesting, but wasn't competent in such areas to devise a safe yet meaningful experiment. The University of Arizona in Tucson did such an experiment also reported in the Science News issue above. Microbiologist Charles Gerber and collegues spread their innocuous virus on an office door handle at a healthcare facility showed up on 40 to 60 percent of the employees depending on door or table, etc initially infected. The virus showed up on bed rails, a a coffee break room and on phones and computers. That is the bad news.
The sorta good news is that when Gerber, et al offered employees hand wipes to disinfect hands and surfaces, that reduced infection rate by 80 percent even thouse only about half the employees used the disinfectant wipes. Science News story by Nathan Seppa.
There are simple protocols and techniques that can greatly reduce hospital and facility disease spread that are inexpensive and effective . Scientists and medical workers should be pushing these protocols and techniques. A zero rate is not unrealistic if South Dakota gets its butt in gear on this.
