Influenza outbreaks occur annually, which affect public health and can have social and economic impacts. The weekly influenza in the Americas situation reports produced by PAHO/WHO demonstrate that influenza viruses A and B are currently circulating. Among the influenza A subtype viruses circulating are influenza A(H3N2) and A(H1N)pdm09.
To reduce the impact caused by outbreaks of seasonal influenza PAHO/WHO reminds Member States facing intense circulation of influenza viruses to maintain their routine surveillance activities, promote appropriate clinical management and disseminate information to the public on preventative measures. Member States of the Southern Hemisphere are also called upon to begin prevention and control preparations prior to the start of the season with the greatest circulation of influenza viruses.
