Critical preparedness, readiness and response actions for COVID-19
Since January 2020, the scientific knowledge on SARS-CoV-2 (the virus that causes COVID-19), how it spreads, and the public health, economic and social impacts of the COVID-19 pandemic have continued to evolve. Many countries continue to demonstrate that SARS-CoV-2 transmission can be controlled. Variants of SARS-CoV-2 have been detected, including four which have been defined as variants of concern. However, the preparedness, readiness and response actions that are needed remain the same. These actions have saved lives and provided countries with more time to enhance emergency response systems; to increase capacity to detect cases and care for patients; to ensure hospitals have the necessary staff, supplies, including structures and systems, to ensure treatment for COVID-19 and non-COVID-19 conditions.
