Influenza is a viral infection that attacks your respiratory system — your nose, throat and lungs. Influenza, commonly called the flu, is not the same as stomach "flu" viruses that cause diarrhea and vomiting.
For most people, influenza resolves on its own. But sometimes, influenza and its complications can be deadly. People at higher risk of developing flu complications include
· Young children under 5, and especially those under 2 years
· Adults older than 65
· Residents of nursing homes and other long-term care facilities
· Pregnant women and women up to two weeks postpartum
· People with weakened immune systems
· People who have chronic illnesses, such as asthma, heart disease, kidney disease and diabetes
· People who are very obese, with a body mass index (BMI) of 40 or higher
Causes
Flu viruses travel through the air in droplets when someone with the infection coughs, sneezes or talks. You can inhale the droplets directly, or you can pick up the germs from an object — such as a telephone or computer keyboard — and then transfer them to your eyes, nose or mouth.
People with the virus are likely contagious from the day or so before symptoms first appear until about five days after symptoms begin, though sometimes people are contagious for as long as 10 days after symptoms appear. Children and people with weakened immune systems may be contagious for a slightly longer time.
Influenza viruses are constantly changing, with new strains appearing regularly. If you've had influenza in the past, your body has already made antibodies to fight that particular strain of the virus. If future influenza viruses are similar to those you've encountered before, either by having the disease or by vaccination, those antibodies may prevent infection or lessen its severity.
But antibodies against flu viruses you've encountered in the past can't protect you from new influenza subtypes that can be very different immunologically from what you had before.
Symptoms
Initially, the flu may seem like a common cold with a runny nose, sneezing and sore throat. But colds usually develop slowly, whereas the flu tends to come on suddenly. And although a cold can be a nuisance, you usually feel much worse with the flu.
Common signs and symptoms of the flu include:
· Fever over 100.4 F (38 C)
· Aching muscles, especially in your back, arms and legs
· Chills and sweats
· Headache
· Dry, persistent cough
· Fatigue and weakness
· Nasal congestion
· Sore throat
Risk factors
Factors that may increase your risk of developing influenza or its complications include:
Age. Seasonal influenza tends to target young children and older adults.
Living conditions. People who live in facilities along with many other residents, such as nursing homes or military barracks, are more likely to develop influenza.
Weakened immune system. Cancer treatments, anti-rejection drugs, corticosteroids and HIV/AIDS 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.
Pregnancy. Pregnant women are more likely to develop influenza complications, particularly in the second and third trimesters. Women who are two weeks postpartum are also more likely to develop influenza-related complications.
Obesity. People with a BMI of 40 or more have an increased risk of complications from the flu.
Complications
If you're young and healthy, seasonal influenza usually isn't serious. Although you may feel miserable while you have it, the flu usually goes away in a week or two with no lasting effects. But high-risk children and adults may develop complications such as:
· Pneumonia
· Bronchitis
· Asthma flare-ups
· Heart problems
· Ear infections
Pneumonia is the most serious complication. For older adults and people with a chronic illness, pneumonia can be deadly
