The influenza A(H1N1) epidemic in Mexico. Lessons learned

Area of Science:

• Public Health
• Epidemiology
• Infectious Disease Control

Background:

• Historical influenza pandemics were anticipated to arise from avian virus strains adapting to humans.
• Mexico established a National Preparedness and Response Plan for Influenza Pandemic in 2003.
• The plan encompassed risk communication, health promotion, healthcare, surveillance, stockpiling, and R&D.

Purpose of the Study:

• To describe the critical moments during the 2009 H1N1 influenza A outbreak in Mexico.
• To identify lessons learned from Mexico's response to the pandemic.
• To share Mexico's experience for the benefit of global health preparedness.

Main Methods:

• The study describes the situation, decisions, and actions taken during the 2009 H1N1 epidemic wave in Mexico.
• It highlights key factors contributing to the control of the first epidemic wave.
• Lessons learned are explicitly pointed out based on the government's response and public engagement.

Main Results:

• Mexico's National Pandemic Influenza Plan was challenged by the emergence of a novel swine-origin influenza A(H1N1) strain in April 2009.
• The implemented strategies and decisions effectively controlled the initial epidemic wave.
• Key factors included strong government support, effective coordination, international collaboration, and public adherence to health measures.

Conclusions:

• Mexico's experience demonstrated the effectiveness of its National Pandemic Influenza Plan.
• Government commitment, inter-agency coordination, international support, and public cooperation were crucial for managing the H1N1 outbreak.
• The Mexican experience offers valuable insights for international pandemic preparedness and response.
