A public health emergency provides an opportunity and need to utilize the power of evidence, science, research and innovation, and practicality to provide rapid solutions. The COVID-19 pandemic did exactly that. It challenged the scientific and public health community from identification to tracking the virus, from characterizing the disease to developing strategies to treat and contain the pathogen. The Pan American Health Organization (PAHO), as an international public health agency working in the region of the Americas, responded to these challenges with extreme vitality, transparency and accountability, and many achievements were made. The PAHO clinical management team put into practice a rapid response program to support evidence-informed decision making (EIDM) in the Region, and in Member States.
