Know the risk factors
What increases my risk for flu?
There are many risk factors for flu, such as:
- Seasonal influenza tends to target young children and older adults.
- Living conditions. Because of a contagious disease, people who live in facilities along with many other residents (nursing homes, military barracks) are more likely to develop influenza.
- Weakened immune system. HIV/AIDS, cancer treatments, anti-rejection drugs, corticosteroids can weaken your immune system. This can make it easier for you to catch influenza and may also increase your risk of developing complications.
- Chronic illnesses. Chronic conditions, such as asthma, diabetes or heart problems, may increase your risk of influenza complications.
- Pregnant women are more likely to develop influenza complications, particularly in the second and third trimesters.
- People with a BMI of 40 or more have an increased risk of complications from flu.

How is flu diagnosed?
According to the Centers for Disease Control and Prevention, the flu can be diagnosed by a description of symptoms, but there are some laboratory tests to identify the strain of flu involved. Tests are more effective if performed within four days of the onset of symptoms.
How is flu treated?
Along with bed rest and drinking plenty of fluids to treat the flu, your doctor may prescribe an antiviral medication such as oseltamivir (Tamiflu) or zanamivir (Relenza). Taking these drugs soon after you notice symptoms, they may shorten your illness by a day or so and help prevent serious complications.
Lifestyle changes & Home remedies
What are some lifestyle changes or home remedies that can help me manage flu?
The following lifestyles and home remedies might help you cope with flu:
- Drink plenty of liquids. Choose water, juice and warm soups to prevent dehydration.
- Get more sleep to help your immune system fight infection.
- Consider pain relievers. Use an over-the-counter pain reliever, such as acetaminophen or ibuprofen to combat the achiness associated with influenza. Avoid using aspirin to children or teens due to the risk of Reye’s syndrome, a rare, but potentially fatal disease.
If you have any questions, please consult with your doctor to better understand the best solution for you.
