"influenza viruses do not occur in all tropical regions of the world."

"There are two other controversial theories for the appearance of human influenza virus. These are controversial because although they seem to explain the occurrence of simultaneous disease outbreaks without discernable connection, there is no biological evidence to support them. One explanation, by Hope-Simpson and Golubev (65-67), is that influenza viruses are spread by humans who are themselves asymptomatic carriers, rather than directly from one acutely infected host to the next."

"Alternative Theories for the Appearance of Human Influenza Viruses
There are two other controversial theories for the appearance of human influenza virus. These are controversial because although they seem to explain the occurrence of simultaneous disease outbreaks without discernable connection, there is no biological evidence to support them. One explanation, by Hope-Simpson and Golubev (65-67), is that influenza viruses are spread by humans who are themselves asymptomatic carriers, rather than directly from one acutely infected host to the next. These carriers supposedly once suffered an acute influenza infection. In these latently infected carriers, seasonal changes correlated with solar irradiation serve to reactivate the virus infection, but in rare cases it may presumably remain dormant until many decades have passed. "

"One noteworthy characteristic of the history of influenza virus in humans is that when a new virus subtype appears and causes a pandemic, the previously circulating subtype usually disappears. This probably occurred in 1918 when emerging HlNl viruses replaced H3-like viruses, in 1957 when the H2N2 subtype replaced HlNl, and 1968 when H3N2 replaced H2N2. It did not occur in 1977, when HlNl viruses reemerged after a 20-year absence from humans. Since 1977, HlNl and H3N2 viruses have cocirculated. The reasons for the sudden disappearance of previously circulating human strains are unknown."

Canada�s legacy of lies on biological weapons

Even in its official 1992 report to a United Nations convention on biological weaponry, Avery writes, the Canadian government produced a "disappointing" and "misleading" document that repeated "half truths" about Ottawa's activity in this field of war research.

The full truth was that Canada was very involved. In the Second World War, Canadian scientists worked with both the British and Americans to develop weaponized anthrax for possible use against Germany and Japan.

Anthrax, Ebola Missing from Army Lab

"Lab specimens of anthrax spores, Ebola virus and other pathogens disappeared from the Army's biological warfare research facility in the early 1990s, during a turbulent period of labor complaints and recriminations among rival scientists there, documents from an internal Army inquiry show.

The 1992 inquiry also found evidence that someone was secretly entering a lab late at night to conduct unauthorized research, apparently involving anthrax. A numerical counter on a piece of lab equipment had been rolled back to hide work done by the mystery researcher, who left the misspelled label ``antrax'' in the machine's electronic memory, according to the documents obtained by The Courant."

"In addition to anthrax and Ebola, the specimens included hantavirus, simian AIDS virus and two that were labeled ``unknown'' -- an Army euphemism for classified research whose subject was secret."
