Answer:
24 hours after symptoms and fever break (with no fever when not taking fever reducing medicine).
Another answer:
Some studies suggest that 24 hours after fever is gone when no longer taking fever reducers, or seven days from the first symptoms whichever is longer. The Centers for Disease Control and Prevention switched to the recommendation above from this recommendation, but some studies have suggested this extra precaution is still a good idea. And in fact, one study said wait until the cough is gone (which could even be two weeks after the other symptoms are gone).
Another answer:
Doctors quoted at the webmd site (listed in the related links section below) say 5-7 days for adults, and 10-14 days for children from the first symptoms. Even longer for people with immune deficiencies.

Can you catch cold from someone on antibotics?
No, if you catch a cold it is because you have been exposed to a common cold virus...being wet and cold is not a factor of catching a cold. You may become ill from exposure to the elements (hypothermia, frostbite, etc.) but you can not catch a cold without being infected by a cold virus.Being on an antibiotic would make no difference since it would be for treating a bacterial infection. The common cold is caused by viruses and are not affected by antibiotics. Antibiotics do not prevent viral infections, but are sometimes used that way in a prophylactic measure against bacteria. However, going in public (wet or dry and cold or hot) with with a fever (indicating you are still fighting an active bacterial infection) is not a good idea for infection control.You often hear it said that being cold can "weaken" your immune system, but that is not correct unless you are talking about the medical condition of hypothermia. Hypothermia is believed to weaken the immune systems of some people. However, feeling cold from being outside with short exposures to the cold weather with or without being wet or with or without a jacket does not produce hypothermia. Hypothermia is a medical diagnosis made by measuring the core body temperature which doesn't change in the cold without long term continued unprotected exposure to extremely low temperatures or without being fully immersed in very cold water.
What is the difference between a contagious cold and non contagious cold?
A contagious cold is caused by viruses that can be easily spread from person to person, typically through respiratory droplets or contaminated surfaces. In contrast, a non-contagious cold usually refers to symptoms caused by allergies, irritants, or other non-viral factors, which cannot be transmitted to others. While both types of colds may present similar symptoms, only the contagious variety poses a risk of spreading to others.

Are antibiotics effective to shorten the duration of a cold or flu?
No, antibiotics are not the right medication for a cold. Antibiotics are for treating bacterial infections. The common cold is caused by a virus, not bacteria, and will not be affected by antibiotics. There may be a situation where a doctor may prescribe antibiotics for a secondary bacterial infection after a cold or flu, but the cold itself can not be treated with antibiotics...it is a waste of money to use them for a cold and is also an unnecessary risk of adverse reactions or allergies to the antibiotics.
