Adaptive and Mutated Strains of the Influenza Virus, Essay Example

Adaptive and mutated strains of the influenza virus have provided emergence of a new strain called H1N1(2009).  This potentially leading towards pandemic conditions that can spread amongst the human population.  Early analysis has indicated that certain protein sequences and amino acid conserving conditions are unique to this strain of virus.  ” Of 47 signatures that separate avian viruses from human viruses by their nonglycoproteins, 8 were human-like in the pandemic (H1N1) 2009 virus. Close examination of their amino acid residues in the recent ancestral swine viruses of pandemic (H1N1) 2009 virus showed that 7 had already transitioned to human-like residues and only PA 356 retained an avian-like K; in pandemic (H1N1) 2009 virus, this residue changed into a human-like R. Signatures that separate swine viruses from human viruses were also present.”  (Shih, 2009)

In a Pandemic situation the burden on respective Health Authorities is enormous. Are there sufficient quantities of vaccine ?  Are there sufficient medical resources to administer the vaccine ? the cost of communicating and minimizing public panic.  In Canada one Medical Officer in the City of Saskatoon stated:   “I don’t think people really appreciate that public health hasn’t had to immunize this volume of people for decades,” said Neudorf, who is also Saskatoon’s chief medical officer.  “The planning to deliver this type of campaign in a short time period has been a huge planning issue that has taken a large volume of staff, and many hours to pull together.” (Fitzpatrick, 2009).

Neudorf  highlighted the need for a “surge capacity” in the health system that provides the necessary facilities, infrastructure and resources to deal with future pandemic crisis situations.  We had the SARS panic in Toronto and now H1N1. It is considered only a matter of time before we face another possibly more sinister crisis.  Emergency preparation is vital if we are to minimise the impact and potential fatalities resulting from an outbreak.  ” The system’s inability to stretch very far was highlighted during the SARS health emergency in 2003 and the public health community is trying to draw attention to the lack of surge capacity, said Neudorf.” (Fitzpatrick, 2009)
