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.
What To Expect. The typical flu incubation period is between 24 hours and 4 days, with the average being 2 days. What this means is that if you are exposed to the influenza virus and become infected, you will start to experience flu symptoms anywhere between 24 hours and 4 days after the exposure. Flu symptoms generally don't come on gradually.
