چکیده
The pandemic influenza A (H1N1) virus (pH1N1) spread quickly throughout the world following the April 2009 outbreak in Mexico, and it was the first major influenza pandemic since 1969. In order to effectively prepare for and respond to future pandemics, it is crucial to fully understand the characteristics of the 2009 outbreak. The objective of this review is to focus on the salient epidemiological features of the 2009 pandemic, the known risk factors for severe disease during infection, and specific vulnerable populations.

متن کاملAmantadine-Resistant among Seasonal H1N1 and 2009 Pandemic Isolated of Influenza A Viruses in Iran
Background and Aims: Influenza A viruses are important pathogens for humans especially in pandemic episodes. Two adamantane derivates, amantadine and rimantadine, are used for prophylaxis and treatment of influenza A virus infections. However, single amino acid substitutions in the M2 transmembrane domain which lead to amantadine resistance of these viruses occur at residues 26, 27, 30, 31 or 3...
