Five common questions about the cold and flu season.
No. The World Health Organization suggests that the flu vaccination may be one the most effective defenses against catching the flu.1 The vaccine itself is made from an inactivated virus that can’t transmit the infection.2 The myth may have developed because people can still get sick after vaccination (until the vaccine takes effect, which can take up to a week or even two). So be careful around people who are sick during that time. Keep in mind that you may live in a geographical area where your risks for getting the flu are low. Before you get the vaccine, be sure to talk to your health care provider to determine if the flu vaccination is right for you.
No. Antibiotics are only useful in fighting bacteria, and both the cold and flu are infections from viruses.3 Sometimes, colds can lead to a bacterial infection in your lungs, sinuses, or ears.3 If that happens, your health care provider may prescribe antibiotics, but only at the time that a bacterial infection is suspected.
Yes. Most healthy adults can spread the flu virus to others a day before their symptoms develop and up to 7 days after becoming sick.4
There is no cure for a cold or the flu. Both have to run their course.3 Any medicine or remedies you try would be to relieve the symptoms of the infection to help you feel better. However, it’s extremely important to remember that even if you take something that makes you feel less congested or reduces your fever, you’re still contagious to other people.5
Yes. Both cold and flu viruses can live outside the body.1 They can survive for periods of time on non-porous surfaces, like desks, keyboards, and countertops, and even porous surfaces, like tissues, clothing, and towels.1 The amount of time varies, depending on a number of factors. That’s why it’s important to wipe down common surfaces at work and wash your hands frequently.
