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.
In the 1999 study kids were found to have spent an average of 6 hours 19 minutes a day with digital media, which the 2010 study showed the amount of time to have increased to 7 hours 38 minutes a day. Kids between the ages of 11 and 14 spent the most time exposed to digital media, 11 hours 53 minutes a day. The youngest kids in this study, those between the ages of 8 and 10, spent an average of 7 hours 51 minutes a day using technology.
