The timing of flu is very unpredictable and can vary from season to season. Flu activity most commonly peaks in January or February in
New Jersey, although it can begin as early as October and continue to occur as late as May. The timing, severity and length of the season may vary from one year to another.
Flu viruses are constantly changing so it’s not unusual for a new flu virus strain to appear each year. The vaccine manufacturers predict the most likely strains of influenza to circulate each season. The vaccine for this season contains the 2 types of influenza A and 1 type of influenza B. There is a new vaccine this year that contains 2 types of influenza A and 2 types of influenza B.
The Centers for Disease Control and Prevention (CDC) recommends a yearly flu vaccine for everyone 6 months of age and older as the first and most important step in protecting against this serious disease. CDC does not recommend one vaccine over another. Talk to your doctor or nurse to help you decide which vaccine is best for you.
Everyday preventive steps that are also recommended include staying away from sick people, washing your hands thoroughly and frequently to reduce the spread of germs and if you are sick with flu, stay home from work or school to prevent spreading flu to others.
It can be difficult to tell the difference between the common cold and the flu. Both are respiratory illnesses but they are caused by different viruses. In general, the flu is much worse than the common cold, and symptoms such as fever, body aches, extreme tiredness and dry cough are more common and intense. Colds are usually milder than the flu and the symptoms are more likely to be a runny or stuffy nose. Colds do not generally do not result in serious health problems, such as pneumonia, bacterial infections or hospitalizations. To know if it is flu, special tests must be done within the first few days of illness. Many physicians offer rapid influenza tests in the office to determine if it is flu.
There are prescription medications called “anti viral drugs” that can be used to treat the flu. When used for treatment, antiviral drugs can lessen symptoms and shorten the time you are sick by 1 or 2 days. They can also prevent serious flu complications, like pneumonia. They are most effective when used within the first day or two after symptoms appear. If you think you have the flu, check with your medical doctor for advice.
