A comparison of severe outcomes during the waves of pandemic (H1N1) 2009

November 8, 2010

The second wave of the pandemic (H1N1) was substantially greater than the first with 4.8 times more hospital admissions, 4.6 times more deaths and 4 times more ICU cases, according to a study published in CMAJ (Canadian Medical Association Journal). However, because of the larger number of people hospitalized during the second wave compared to the first, the percentage of people with severe outcomes was smaller.

The researchers compared demographic and clinical characteristics as well as outcomes of patients with (H1N1) admitted to hospital during the first wave with those admitted during the second wave and post-peak period of the .

In the first wave, Nunavut, Manitoba and Quebec had the highest rates for . In the second wave, all provinces and territories were affected with the Maritimes provinces, Alberta, British Columbia, the Yukon Territory and the Northwest Territories experiencing much higher rates of hospital admission than in the first one. Quebec and Ontario were impacted in both waves, with Quebec reporting the highest number of hospitalizations and Ontario reported the most deaths overall.

At the height of the first wave (May 31 to June 20, 2009), 9.4% of hospital admissions, 10.1% of ICU admissions and 10% of deaths occurred. At the height of the second wave (October 25 to November 14, 2009), 51% of overall hospital admissions, 49.4% of ICU admissions and 53% of deaths occurred.

ICU admissions and deaths as a percentage of hospitalizations went down in the second wave.

"The second wave was substantially larger and, although the patients admitted to hospital were older and more of them had underlying conditions, a smaller proportion had a severe outcome," writes Melissa Helferty, Public Health Agency of Canada and coauthors. "The differences are thought to be due mainly to public health and clinical interventions implemented between the first and second waves."

"A national seroprevalence survey at the end of the first wave would have allowed us to better qualify the severity of the cases in Canada and permitted a more accurate comparison with other countries," conclude the authors.

This article is another "ordered" Propoganda and fear mongering trick to "push in" the mystical , rather "imaginary" H1N1 which actually did not kill anyone even if it kills , killed too less than other diseases such as Hepatitis C, Malaria, Cholera in Haiti are still continuing to kill Millions of people worldwide annually and World Health Organization very bizzarely and strangely points out to H1N1 as the "MOST DANGEROUS" "LEVEL6 " PANDEMICS "LABEL" and orders 200 countries worldwide to "manufacture" so called 'drugs and vaccines" which are all fake and "placebo" in some sense and make a contract for Hundreds of Billions of $ out of the State Budgets, out of the pockets of people and give them out to "BigPharma" so that they would manufacture drugs and would eat up Billions of dollars for "NonExistent" disease which has killed 3 thousand people somewhere in Africa..
