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.
The average kid sponges in 2.5 hours of music each day, almost five hours of TV and movies, three hours of Internet and video games, and just 38 minutes of old-fashioned reading, according to a new study by the Kaiser Family Foundation. That adds up to 75 hours of media every week. And that doesn't even include the hour and a half spent text messaging each day, and the half hour kids talk on the cell phone. In fact, the cell phone is one of the gadgets that makes this all possible for kids.
