Signs and Symptoms of Flu
People who have the flu often feel some or all of these signs and symptoms:
- Fever* or feeling feverish/chills
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Fatigue (very tired)
- Some people may have vomiting and diarrhea, though this is more common in children than adults.
How flu spreads
Most experts believe that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or possibly their nose.
Period of contagiousness
You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for an even longer time
Flu season: It’s not too late to vaccinate!
Myth: Once you have the flu you won’t catch it again that year.
Fact: There are several strains of flu viruses that circulate every year, so even if you get the flu once, your body is still susceptible to the other viruses.
This year’s vaccine protects against the 3 most common flu viruses: Influenza B, Influenza A [H1N1] and influenza A [H3N2]
Getting the vaccine is one of the best ways to promote your health in the New Year! Even though you can get the flu as early as October flu season typically hits after the start of the New Year. Bases on data from previous flu seasons the peak time for flu outbreaks is January to March.
The flu vaccine takes a couple of weeks to develop the antibodies needed to fight the virus. It is important to get the vaccine as early as possible.
Preventing the Flu: Good Health Habits Can Help Stop Germs
The single best way to prevent seasonal flu is to get vaccinated each year, but good health habits like covering your cough and washing your hands often can help stop the spread of germs and prevent respiratory illnesses like the flu. There also are flu antiviral drugs that can be used to treat and prevent the flu.
1. Avoid close contact.
Avoid close contact with people who are sick. When you are sick, keep your distance from others to protect them from getting sick too.
2. Stay home when you are sick.
If possible, stay home from work, school, and errands when you are sick. You will help prevent others from catching your illness.
3. Cover your mouth and nose.
Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick.
4. Clean your hands.
Washing your hands often will help protect you from germs. If soap and water are not available, use an alcohol-based hand rub.
5. Avoid touching your eyes, nose or mouth.
Germs are often spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth.
6. Practice other good health habits.
Clean and disinfect frequently touched surfaces at home, work or school, especially when someone is ill. Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids, and eat nutritious food.
