The WHO developed an alert system from May 2021 to June 2022 to assess and respond to public health risks related to COVID-19, analyzing data from 237 countries.
A three-stage mixed methods approach was utilized to predict future deaths and adjust alert levels based on context, leading to the creation of a watchlist for countries needing assistance.
The system facilitated significant support, including over $27 million in emergency funding and medical supplies, while demonstrating the potential for similar future applications in managing outbreaks.
COVID-19, caused by SARS-CoV-2, was declared a public health emergency in January 2020, with early studies showing that over 80% of deaths were among individuals aged 60 and older.
The World Health Organization developed strategies to prioritize vaccine distribution, emphasizing the importance of vaccinating at-risk populations, particularly older adults, aiming for full vaccination coverage.
Data analysis revealed that people aged 60 and above made up more than 80% of COVID-19 deaths globally, with significant mortality impact seen in lower and middle-income countries, highlighting the urgency for effective vaccine rollout.*
