Real-Time PCR Assays. Real-time reverse transcriptase-polymerase chain reaction (RT-qPCR) is the most widely used diagnostic assay for detecting norovirus. This assay detects the genetic material (RNA) of the virus. It can be used to test stool, vomitus, and environmental specimens.
Sixty-five percent of children under eight years old watch television daily. On average, they spend about an hour and a half (100 minutes to be exact) watching TV every day. As a group, children under eight spend an average of 25 minutes per day playing video games. 66% of all children under the age of two have watched television. Television watching typically begins at 9 months of age.
Gameplay is also on the rise â one study shows that average daily video game play among kids ages 8 to 18 rose from 26 minutes per day in 1999 to almost 110 minutes (nearly two hours) per day by 2009. The numbers are even higher for boys, 25 percent of whom play video games for four or more hours per day.
