A/H1N1 Pandemic Spreads at
Unprecedented Speed, Says WHO

The A/H1N1 influenza pandemic has been spreading at an unprecedented speed, much faster than other pandemics in history, the World Health Organization (WHO) recently said.

"In past pandemics, influenza viruses have needed more than six months to spread as widely as the new H1N1 virus has spread in less than six weeks," the UN agency said in a briefing posted on its website.

The agency will no longer issue the global tables showing the numbers of confirmed cases for all countries, because the number of infections is increasing so fast in many countries that it has become almost impossible for them to follow through laboratory tests, said the WHO briefing.

Influenza A virus subtype H1N1, also known as A/H1N1, is a subtype of influenza virus A and the most common cause of influenza (flu) in humans. Some strains of H1N1 are endemic in humans, including the strain(s) responsible for the 1918 flu pandemic which killed 50–100 million people worldwide. Less virulent H1N1 strains still exist in the wild today, worldwide, causing a small fraction of all influenza-like illness and a large fraction of all seasonal influenza. H1N1 strains caused roughly half of all flu infections in 2006. Other strains of H1N1 are endemic in pigs and in birds.

In March and April 2009, hundreds of laboratory-confirmed infections and a number of deaths were caused by an outbreak of a new strain of H1N1.

H1N1 Swine Flu: Barack Obama
and the First Deadly Mistake

By Lifegen.de

The H1N1 swine flu hits the US, and for the first time President Barack Obama seems to make a deadly mistake: A disease spread simulation has emphasized that flu interventions must be imposed quickly, if they are to be effective. Researchers writing in the open access journal BMC Public Health have shown that staying at home, closing schools and isolating infected people within the home should reduce infection, but only if they are used in combination, activated without delay and maintained for a relatively long period. The President should have acted by enforcing social separation - but economic items seem to be more important.

What all the President's men should have known: Professor George Milne and his colleagues from the University of Western Australia (UWA) simulated the effect of social distancing on the spread of a flu virus within a small town. Their research used a detailed, individual-based model of a real community with a population of approximately 30,000 (Albany, Australia) using simulation software engineered by UWA’s Dr Joel Kelso. Milne said, “Our results suggest a critical role of combined social distancing measures in the potential control of a future pandemic. Non-pharmaceutical social distancing interventions are capable of preventing less-infectious influenza epidemics and of significantly reducing the rate of development and overall burden of the worst epidemics”.
