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.
Two thirds of this time is spent with âscreen mediaâ (TV, computers, the Internet, etc.) while reading is less than 20 minutes per day. The time spent with on screen media dramatically increases from the toddler to preschool to school-age years. Children under two have a screen time average of 53 minutes per day.
