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.
The time between the exposure to the virus and the symptoms to appear is called the incubation period. The normal incubation period for flu is about 3-5 days. After the incubation period, you start displaying symptoms and excreting enough viruses to infect people around you. It will start with a mild headache, but the next day, you will have a few aches with a low fever. It will turn into a high fever on the third day with a runny nose.
