ABSTRACT

The influenza virus is a RNA virus that belongs to the Orthomyxoviridae family. This virus shows high mutation ability and is responsible for many respiratory diseases. It also represents a high emerging pandemic risk. During 2009, an outbreak of influenza A H1N1 variety featured by specific recombination pig-bird-human, occurred with an epidemiological focus in Mexico. The World Health Organization (WHO) categorized this outbreak as an imminent pandemic disease, due to many cases that were recorded within the country and abroad. In the present study, we report the epidemiological monitoring of four years of molecular diagnosis of influenza B and the different strains of influenza A, using the reverse transcription and real time polymerase chain reaction (RT-PCR One Step) technique. The results show that cases of influenza A H1N1 have decreased as compared to 2009, when the outbreak started; however, the risk of outbreaks of other variants does exist in the winter months.
