When it comes to streaming HD video, you'll need a broadband speed, or bitrate, that's capable of handling a progressive scan rate of 720p. Since your HD-capable screen is refreshing the screen 60 times per second, this means ensuring that all those video frames are received and ready to play before they're needed.
The Flu Is Contagious Most healthy adults may be able to infect other people beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children may pass the virus for longer than 7 days. Symptoms start 1 to 4 days after the virus enters the body.
People also catch the flu by touching surfaces with the virus on them and then touching their eyes, nose or mouth. After exposure to the flu virus, many people begin to experience symptoms within one to seven days. The flu often spreads rapidly within groups, reports MedlinePlus. Once it arrives in a school, students get sick within two to three weeks. A high fever, between 102 and 106 degrees Fahrenheit, is often the first sign of the flu.
