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.
Nine out of ten children play video games, and many of them play for hours a day. On average, children play video games two hours a day with 64 percent of all American children playing at least one hour a day (Sheff 3). Part of this obsession is because most games always contain a new threat or challenge, and this creates a compulsion to continue playing.
