Approximately 36,000 flu-related deaths occur each year in the United States, according to the Centers for Disease Prevention and Control. Although most of these deaths are not directly caused by influenza, it is thought that the flu virus aggravates existing medical conditions and contributes to the development of respiratory infections which are the primary cause of death. As of 2010, most medical professionals believe an annual vaccination is the best preventive measure to avoid contracting seasonal flu.
History
Since the beginning of recorded history, viral infections have taken a toll on the human population. According to Stanford University, as far back as the Middle Ages, medical authorities believed infectious disease was transmitted through contact with an infected person. During the Influenza Pandemic of 1918, the sick were isolated, large gatherings were prohibited and the healthy population was encouraged to don protective clothing. Although modern science has a clearer understanding of viral infections, many of the same preventative measures remain in place today.
Facts
The flu virus is transmitted from person to person through body contact, by touching contaminated surfaces or by being sneezed or coughed upon by an infected person. Although second hand transmission is possible-for example shaking hands- GlobalSecurity.org says direct infection from sneezes and coughs is more likely.
Considerations
Hand washing, avoiding crowds and keeping one's hands away from the face remain the best way to prevent spread of the flu. However people who are in good health and have adequate nutrition are much less likely to contract any virus. In a joint study by Oregon State University and Cedars-Sinai Medical Center and reported by Mike Adams of Natural News, sufficient levels of vitamin D activate the immune system and destroy invading microorganisms. Vitamin D also plays an important role in prevention of inflammation, a major cause of death in flu victims.
Immune Support
The immune system is a whole-body network of cells, tissues and organs whose sole responsibility is to fend off attacks by viruses and infections. When the body is in good health, the immune response is strong and able to resist outside assaults. A healthy diet consisting of natural, unprocessed foods without additives, provides the body with the building-blocks necessary to stay healthy. Water, fresh air and sunshine are also necessary components.
Supplementation
Vitamin supplements, herbs and so called green "power foods" may help to strengthen the immune response to the flu virus. Spirulina, a natural food also available in supplement form, is a source of protein and other nutrients. Some believe herbs such as olive leaf extract and echinacea enhance the immune system making it easier to resist colds and other communicable diseases. Studies continue to examine the efficacy of astragalus, an ancient Chinese remedy prescribed for treatment of viral infections, and believed to serve as an immune stimulant.
