How does the flu spread?

ANSWER

Just like cold viruses, flu viruses enter your body through the mucous membranes of the nose, eyes, or mouth. Every time you touch your hand to one of these areas, you could be infecting yourself with a virus, which makes it very important to keep hands germ-free with frequent washing to prevent both flu and cold symptoms.
