What are zoonotic flu viruses of public health concern? Flu viruses of public health concern include the following: Zoonotic origin flu viruses that have not caused past human infection s but that may have the potential to cause human infections.
Scientific studies on mutations of the H5N1 virus When: December 20, — June 21, Where: United States of America Why: These papers described how to synthesize a strain of the H5N1 avian flu virus. Unlike the original strain, this new form of H5N1 was highly transmissible and possibly much more deadly.
Specifically, it advised the deletion of sections of the research which described, in detail, how the original strain could be mutated to create the new strain.
In this debate, two arguments were established. The first was that the papers should be censored for the sake of biosecurity.
The other was that all information must be released for the sake of scientific progress. Similar research papers have been brought before the NSABB for review, such as studies on the reconstruction of the H1N1 influenza virus, which was responsible for the Spanish flu pandemic inyet this study was reviewed and published with little difficulty Ledford 9.
This category of virus has produced numerous different strains over the past few centuries. Although most strains are harmless to humans, some present a great danger to humanity.
Indeed, a few strains in the past century generated outbreaks that ravaged societies throughout the world. In addition, the H2N2 and H3N2 viruses, otherwise known as the Asian Flu and Hong Kong Flu respectively, are estimated to have killed approximately 1 million andpeople during their outbreaks Thomas These major outbreaks were followed by relatively smaller ones such as the swine flu until the most recent strain, H5N1, appeared in Due to the massive losses of life as a result of these outbreaks, scientists, health organizations, and governments around the world have viewed appearances of virus strains from the HPAI family with severity.
Despite these efforts however, the virus has since infected people, become widespread in parts of East and Southeast Asia and the Middle East, and has led to the culling of hundreds of millions of birds Kawaoka If, through experimental mutations, it became even more transmissible and deadly to humans, then the new strain could potentially wreak havoc globally.
A Human Mortality Chart for H5N1 since January However, the history of the H5N1 strain does not explain the censorship of its research in particular, as opposed to research on the Spanish Flu, which historically had a far more devastating impact on the world than the H5N1 strain.
This act of censorship stemmed from the nature of the research of the H5N1 virus strain. While research on the H1N1 virus strain focused primarily on its reconstruction, the research regarding the H5N1 strain focused on the creation of more transmissible strains of the virus to humans.
However, it was a disease transmissible between humans that rapidly infected thousands of people worldwide and killed seven hundred seventy-four within a few months SARS.
This outbreak illustrated just how quickly a disease could transcend regional and global boundaries and emphasized the importance of suppressing outbreaks before they become a worldwide epidemic.
Hence, the NSABB and delegates of the scientific community were opposed to the publication of these research studies. If an outbreak involving a mutated form of H5N1 did occur, they feared that the world would lack the resources to contain and defend itself against.
Below is a video giving an overview of the entire H5N1 controversy. Furthermore, in the research conducted by Dr. Ron Fouchier and his team, only five mutations all of which occur naturally in nature were made to the test H5N1 virus strain before it became easily transmissible to ferrets Evans This revelation highlighted just how dangerous the virus could become if the right mutations were made to create a perfect, genetically-engineered bioweapon.This factsheet describes CDC's avian influenza (bird flu) research and its public health impact.
(FDA) cleared new CDC developed molecular laboratory tests to aid in the diagnosis of Asian A(H5N1) bird flu viruses in human respiratory specimens. CDC has since expanded its molecular test kits to detect other flu viruses, such as Asian .
