As we enter the heart of winter, it\u2019s that time of year to start thinking about influenza (flu) prevention.\u00a0 The Centers for Disease Control and Prevention (CDC) monitors the prevalence of flu and recently announced that influenza activity in the United States is currently increasing. New Jersey is also seeing an increase in flu activity in the past several weeks.<\/p>\n

Influenza is a very contagious illness that tends to occur in outbreaks. The majority of illnesses caused by the flu are self-limited and often mild to moderate in severity. There are two main types of influenza viruses: A and B. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. The emergence of a new and very different influenza virus to infect people can cause influenza outbreaks and epidemics.<\/p>\n

The typical flu symptoms include acute onset of muscle aches, fever as high as 103 degrees Fahrenheit, upper respiratory symptoms including sore throat, runny nose, cough, and extreme fatigue.<\/p>\n

Gastrointestinal symptoms are less common in flu. Although often called the \u201cstomach flu,\u201d these type of illnesses that cause nausea, diarrhea, and vomiting are typically triggered by rotaviruses or bacteria and aren\u2019t related to influenza. While these illnesses can occur anytime of the year, they are also highly contagious and common in the winter months as well while people are together in close quarters indoors. It is not unusual for these illnesses to spread quickly through families, school groups, or others in close proximity.<\/p>\n

While everyone should be concerned with influenza, certain people are at high risk for complications of the flu. This includes the elderly, the very young, and people with chronic medical conditions including diabetes, COPD, and those who are immune compromised.<\/p>\n

Prevention is the key to decreasing the incidents of outbreaks and epidemics. The CDC recommends flu vaccine for all individuals 6 months of age and older. The vaccination period for the flu begins in August and ends in April. There is a two-week lag time between receiving the vaccine and having adequate immunity against the flu. Several vaccines are available for influenza A and B. These vaccines contain antigens that were developed based on best medical knowledge from prior history of influenza outbreaks. An\u00a0antigen<\/em>\u00a0is any substance that causes your immune system to produce antibodies against it.<\/p>\n
