Resumen

Influenza A viruses are one of the most important pathogens for humans. Two main subtypes of these viruses, A(H3N2) and A(H1N1), are currently circulating among human populations. However, the highest mortality rates typically occur in seasons when the circulation of the influenza A(H3N2) viruses predominate over the influenza A(H1N1) and the influenza B viruses. On the 11th of June 2009, the World Health Organization established phase 6 and confirmed that an influenza pandemic was taking place. This pandemic was caused by a novel A(H1N1)pdm09 influenza strain that emerged in Mexico in April 2009, and then spread worldwide through human to human transmission. The A(H1N1)pdm09 influenza strain was first detected in Cuba in May 2009, and later spread throughout the country.
