how long after exposed to the flu do you get it.
During this period anything the person touches can also become infected with germs. (They can be sick up to 2 weeks.) Because a cold is caused by a virus, antibiotics will not help. The flu, (depending upon the strain of virus), can appear between 1 to 4 days after the virus enters the body. So it presents faster and harder than a cold. Rather than starting with nose or throat, it usually begins with a strong headache, body aches, painful to swallow, exhaustion and a high fever with chills.
