PAHO/WHO Response

  • In this week’s press briefing from PAHO, Dr. Jon Andrus recounted important topics about influenza A(H1N1). Click here for transcripts of the press briefings. Highlights include:
    • PAHO encourages all people at risk to be vaccinated for seasonal influenza as soon as possible. Those people are
      • older adults and young infants,
      • pregnant women,
      • and people with chronic disease.
    • Countries should continue implementing their emergency response plans.
    • PAHO continues to support countries with antiviral medications, laboratory support, and when they are available, vaccines.
    • This epidemic will take the greatest toll on the poor, who are the most vulnerable. We need to provide all the support we can to poorer countries to help them prepare and respond.
  • Teams of experts recruited by PAHO from the Region and deployed to Mexico and countries in Central America continue to provide support in various areas including: logistics, emergency management, health systems, mental health, risk communication, epidemiology, and public health.
  • The Director-General of the World Health Organization, Dr. Margaret Chan, convened a High-Level Consultation for all Member States at the start of the Sixty-second World Health Assembly to discuss lessons learnt, and to highlight the challenges that now confront the world community from the influenza A(H1N1).
