Agonist Exclusive - After years of international concern about an avian flu H5N1 pandemic; the world is awaiting the 6pm Geneva time WHO press conference, at the WHO boardroom where it is expected that the Director-General Dr. Margaret Chan will announce that the world is officially dealing with the novel H1N1 influenza (swine flu) at pandemic level. Scotland's Health Secretary Nicola Sturgeon told Scottish lawmakers "A move to level 6 is not a verdict on the severity of the virus," she said. "It simply means that the extent of global spread now fulfills the definition of a pandemic." WHO considers a disease pandemic when transmission between humans becomes widespread in at least two regions of the world.
Emerging in Mexico and California in March 2009, the novel H1N1 influenza, commonly known as swine flu, has achieved what many feared Avian Flu would do since November 2003, spread rapidly 'around the world in 80 days', with sustained transmission on several continents, especially in Australia.

Surprisingly, it has not yet apparently spread to the African continent, but from its beginnings in California and Mexico the virus has penetrated Canada, Australia, Japan, the UK and 74 other countries. Hundreds of thousands of people with the disease is likely as mild cases may not have been detected.
The death toll remains low, and statistically infection levels remain commensurate with seasonal flu outbreaks. Concern of mutation and a second wave of infections in late 2009 with the onset of winter in the northern hemisphere may indicate that the virus may prove as deadly as the three previous pandemics in the past 100 years. (The "Spanish flu", a H1N1 virus was identified early in March 1918 in Kansas and spread by October 1918 to become a world-wide pandemic on all continents infecting one third of the world's population. Especially deadly and virulent it killed over 50 million. The "Asian Flu", an H2N2 virus, was first identified in China in late February 1957, caused about 2 million deaths globally. The "Hong Kong Flu" a H3N2 virus was first detected in Hong Kong in early 1968 and killed over one million people worldwide in the next two years.) However the raising of the alert level by WHO to level 6, BBC - does not mean the world is going to see the spread of the disease on the scale as deadly as that of the 1918 Spanish Flu.
In developing nations health facilities will be overwhelmed, whilst in the developed world drugmakers will increase production of a vaccine for the novel H1N1 influenza strain, whilst at the same time providing vaccines for older H1N1, H3N2 and type B viruses which are still in circulation. It appears that a vaccine may not be ready until October. Governments will be forced to budget more money to curb the spread of the virus, by increasing vigilance at seaports and airports, and providing increased medical resources including anti-viral medications and masks. Quarantine of school children, sporting teams, and travellers will increase.
With its propensity to attack the young and the elderly and those already ill with chronic illness; the schooling systems, aged care providers and medical and nursing resources will need to adapt to meet the challenge of the virus, especially if it mutates into a more virulent and deadly strain.
REUTERS - David Heymann, a former top WHO official now chairing Britain's Health Protection Agency, said that countries had tried to contain the virus through measures including school closures during the current phase 5. This has extended the precious time needed to prepare for a full-blown pandemic. "During phase 5, the government and people in the U.K. have had the time to prepare for a pandemic -- this has hopefully decreased any surprise and concern that might be associated with a WHO announcement of phase 6, if one is made," he told Reuters. As it spreads in humans, science cannot predict what course the virus will take, the disease it causes and the age groups infected, Heymann said. "The severity of that disease, the effectiveness of antiviral drugs and the stability of the virus must all be watched closely," he added. A pandemic could cause enormous disruption to business as workers stay home because they are sick or to look after family members and authorities restrict gatherings of large numbers of people or movement of people or goods.
