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.
After surveying the parents of 350 children aged six months to 4 years old during October and November of last year, researchers learned that 75 percent of 4-year-olds have smartphones. About 97 percent of kids under age four have used a mobile device and 50 percent of children the same age had their own television. Nearly 100 percent of kids started using smartphones before their first birthday. Shockingly, nearly all (97 percent) children used mobile devices before their first birthday.
