CAUSES & RISK FACTORS
What causes colds and the flu?
Viruses cause colds and the flu. More than 200 different viruses can cause colds. Not as many viruses cause the flu. That’s why there’s a shot available for the flu and not for colds.
Can a cold or the flu be prevented or avoided?
There are things you can do to reduce your risks for colds and flu. They include:
- Wash your hands frequently. Use soap. This stops the spread of germs.
- Eat healthy, exercise and get enough sleep. These things boost your immune system.
- Cough and sneeze into the inside of your elbow (not your hands).
- Clean common surfaces such as tables, counters toys, door handles and bathrooms. Use anti-bacterial disinfectants.
- The best way to avoid getting the flu is to get the influenza immunization. You should get the immunization when it becomes available each fall (in October or November), but you can also get it any time throughout the flu season (into December, January and beyond). The immunizations work by exposing your immune system to the flu virus. Your body will build up antibodies to the virus to protect you from getting the flu. The flu shot contains dead viruses. The flu shot is safe for adults and all children 6 months of age and older and it is recommended for everyone over 6 months of age to receive a yearly flu shot. You cannot get the flu from the flu shot. Some people who get the flu shot will still get the flu, but they will usually get a milder case than people who aren’t immunized.
The flu shot is especially recommended for:
- adults 65 years of age and older,
- children six months to 5 years of age,
- pregnant people,
- individuals with chronic medical conditions (heart disease, asthma, diabetes, etc.),
- people at high risk of COVID-19 related illness,
- people who live with or care for people in the high-risk groups are also encouraged to get a flu shot because they’re more likely to spread the flu to those in high-risk groups.
Colds and the flu treatment
There’s no cure for the common cold or the flu. Antibiotics do not work against the viruses that cause colds and the flu. You can do some things to ease your symptoms. For a low fever, mild aches, and pains, take products such as acetaminophen (one brand: Tylenol), naproxen (one brand: Aleve) or ibuprofen (one brand: Advil). Drink plenty of fluids. Get as much sleep as you can. Stay home to avoid spreading germs to others.
Your healthcare provider may prescribe an antiviral medicine for the flu. This only shortens the length of time you are sick. These medicines come as pills, syrup or in an inhaler. The inhaled type may cause problems for some people who have asthma or chronic obstructive pulmonary disease (COPD).
When easing a child’s symptoms, acetaminophen (one brand: Children’s Tylenol) can help ease pain and lower a fever. Be sure you are giving your child the correct dose according to their age and weight.
Nasal sprays and decongestants are not recommended for young children, as they may cause side effects. Cough and cold medicines are not recommended for children, especially those younger than 6 years of age. There is also little evidence that cough and cold medicines and nasal decongestants are effective in treating children.
To treat your child’s cold or the flu, make sure your child rests. Give them plenty of fluids. Use a humidifier to moisten the air in your child’s bedroom. This will help with nasal congestion. Use a saline nasal spray to thin nasal mucus. Use a bulb syringe to suction mucus out of your baby or child’s nose.
Living with a cold or the flu
Cold and flu symptoms are uncomfortable. You will not feel well for the time it takes your cold and flu to run its course. Ease your symptoms with rest, fluids, over-the-counter medicine, and blowing your nose.
