Here is a link to a document published en 1986, titled: “Ammonium chloride slows transport of the influenza virus hemagglutinin but does not cause mis-sorting in a polarized epithelial cell line”.
If you read the PHAC reports (FluWatch), you will find a new version of the H1N1 were out there weeks before the first influenza outbreak registered by Canada in the week ending on december 6th, 2008. This version is 100% resistant to Tamiflu.
Here is a news report from Milenio Diario and El Universal (both Mexican newspapers), reporting that on october 25th, 2008 the downtown and coast side near the Port of Veracruz was evacuated, due an ammonia toxic cloud, caused by an accident. (the report is in spanish).
Could it be possible that the accident had turned Veracruz and sorroundings into a big laboratory, changing the already present H1N1 virus‘ form, or reducing it’s virulence?
Is there more to be concerned about?
