  • 7 March 2014: Carbapenemases of type New Delhi Metallo-?-lactamase (NDM) – update

    Epidemiological Alerts and UpdatesIn light of the spread of microorganisms with the New Delhi Metallo-?-lactamase (NDM) resistance mechanism, both across bacterial species and across geographic boundaries, the Pan American Health Organization / World Health Organization (PAHO/WHO) emphasizes the importance of strengthening established surveillance and control strategies to prevent further spread of this resistance mechanism.

  • 27 June 2013: Vancomycin-resistant Staphylococcus aureus – situation in the Americas

    Epidemiological AlertsIn light of the isolation of the first Staphylococcus aureus resistant to vancomycin in Latin America, the Pan American Health Organization/World Health Organization (PAHO/WHO) recommends that Member States continue to establish and maintain their capacity for rapid detection and reporting of this resistance mechanism to antibiotics for the implementation of infection prevention and control measures associated with health care.


  • 22 November 2011 – Carbapenemases of type New Delhi Metallo-β-lactamase (NDM)

    Epidemiological Alerts Due to the recent finding of carbapenemasas of New Delhi metalobetalactamasa (NDM) type in isolations of Klebsiella pneumoniae in Guatemala, the Pan American Health Organization/World Health Organization (PAHO/WHO) emphasizes the importance of the surveillance and detection in the Region of this resistance mechanism that increases morbidity and mortality of the infections associated with health care.

  • 15 July 2011: Multi-Resistant Neisseria gonorrhoeae – situation in the Americas

    Epidemiological Alerts In light of the identification by scientific communities of a strain of gonorrhea resistant to all microbial treatments available for sexually transmitted infections (STIs), the Pan American Health Organization recommends informing health workers, institutions, and nongovernmental organizations that work in the prevention and control of STIs about the risk of resistance in this strain, and in particular strengthen the surveillance in each country regarding the appearance of strains with an unusual profile.
