Colds and flu are caused by viruses. There are more than 200 known viruses and no known cure. They can be spread through the air or by touching an object just held by someone with the virus. A flu virus is more active from fall to early spring: a cold virus is not seasonal.
Besides the time of year you're sick, how can you tell if you have flu or a cold? Colds can have some flu-like symptoms that develop over a dew fays. Flu has additional symptoms that develop within 48 hours of infection. These symptoms can last for a week or more.
While you have to let a virus run its course, some ideas that might aid your Cold
and Flu Defense include:
- Drink plenty of fluids such as water or natural fruit juices. Aim for eight 8-ounce glasses per day.
- Get plenty of rest (eight hours of sleep every night).
- Reduce stress.
- Use over-the-counter medications to ease your specific symptoms.
- Wash you hands thoroughly.
- Take vitamins. Vitamin C and zinc gluconate may stop cold virus symptoms.
If any signs or symptoms of cold and flu continue for more then one week, call you primary care physician (PCP). To avoid drug complications, if you are taking any prescription medications, check with your PCP before also taking over-the-counter medications.
