An expert panel of 29 members is set to investigate WHO records with reference to swine flu spread last year in June on Wednesday. It would check the confidential papers between the U. N. body and drug companies.

Committee chairman Harvey Fineberg said that swine flu was declared as a deadly disease in June last year, and panel will hunt for the records and association of H1N1 strain before and after it is declared as an epidemic.

He also told the reporters that we are looking for some important documents related to swine flu which can be located at WHO or may be kept somewhere else.

He further added that confidential papers include "contractual or letters of understanding" between the pharmaceutical industry and WHO. WHO has declared few agreements with industries as confidential which panel want to examine and its request has been fulfilled.

WHO Director-General Margaret Chan, underneath this criticism, assemble the panel and recommend the panel to undergo "credible and independent review" and she promised that this review would be transparent.

It was criticized that a Geneva based company has signed few confidential agreements to give private access to national decision makers but the company denied any such allegations.

Last week a meeting was held by WHO 193 members where these members expressed that we should consider ourselves lucky that swine flu was not deadlier.

Some of the companies which were benefited from the spread of swine flu were, Switzerland's Roche Group, its sales of Tamiflu antiviral medication jump by 2 billion Swiss francs ($1.74 billion), British firm GlaxoSmithKline PLC, its sale of both vaccines and its antiviral Relenza shoots up and France's Sanofi-Aventis SA and U. S.-based Baxter International made vaccines in large amount. Few companies have donated medicines to poor countries.

Panel found that last year WHO has declared 18,036 deaths from the H1N1 which was fewer than people died of seasonal flu during the same period.

Fineberg said that it was expected that panel review will be completed next year and will be made public.
