"In doing so, it is difficult to find evidence of 1918-like waves herald waves, or other such phenomena," they noted. The most recent flu pandemics, occurring in 1957 and 1968, "generally exhibited no more than one (mostly seasonal) recurrence" before settling down into relatively innocuous seasonal flu, [experts] said.
Overall, "examination of past pandemics reveals a great diversity of severity," Morens and Taubenberger said, adding that "some newer evidence [is] casting doubt on original herald wave theories."
One infectious-disease expert called the new analysis "absolutely correct."
Looking back at 20th century flu pandemics, "secondary waves have pretty much been either the same or even of less epidemiologic significance than the first wave," said Dr. Pascal James Imperato, dean of the school of public health at SUNY Downstate Medical Center in New York City.
Americans eat a diet style that weakens their normal resistance to simple viral infections. In spite of advances in science that reveal the critical importance of thousands of protective micronutrients in the natural plant kingdom, much of the modern world consumes a diet rich in processed grains, oils, sweets and animal products. In the United States, for example, less than five percent of total calories consumed come from fresh fruits, vegetables, seeds, and nuts. These are the foods that are richest in micronutrients.
The key to health is nutrition per calorie. Those of us who eat the Standard American Diet (SAD) have a very low nutrient (per calorie) intake. This chronic malnourished condition is the true life-threatening epidemic in the modern world, resulting in a medical care crisis and untold tragedies. And this ubiquitous malnourishment may also eventually enable the Avian influenza viruses to spread more easily and develop into virulent forms. With the ubiquitous consumption of fake foods such as white bread, pasta, oil and sugar, nutritional incompetence is the norm.
The flu is a simple viral illness which a healthy body has scores of adequate defenses against. No flu, including the bird flu, is any match for a well-nourished immune system.
