The New A Platform to Support the Generation and Use of Health Economics Research to Tackle COVID-19

Since the beginning of the COVID-19 outbreak, the scientific community has worked around the clock to produce evidence to support decision-makers in all aspects of pandemic management. As of April 2021, there are more than 78,000 articles published in peer reviewed journals and pre-prints (as indexed by Those unprecedented collective research efforts have supported decisionmakers across the world on some of the toughest choices in decades, from closing economies, to procuring vaccines and medical supplies and equipment, and preparing for the uncertain year ahead.

The COVID-19 Multi-model Comparison Collaboration Releases Its First Two Outputs

Since April 2020, a group of national governments, funders, and development partners supporting COVID-19 responses in low- and middle-income countries have been working together as the COVID-19 Multi-model Comparison Collaboration (CMCC) to support the use of epidemiological models during the COVID-19 pandemic. Today, the CMCC releases its first two outputs—an important step towards enhancing the informed use of models in COVID-related policymaking.

The Indirect Health Effects of COVID-19: Lockdown Measures and Service Provision

As we head into June, reports have continued to emerge that highlight the magnitude of the indirect effects the COVID-19 pandemic is having on  health systems around the world. The pandemic has created additional barriers for patients accessing essential care, whether it be restrictions on movement, transportation restrictions, stigma, impoverishment from loss of livelihoods, or avoidance of care due to concerns over contracting the virus.

Applying Caution with Unmitigated Scenarios: A Closer Look at Non-COVID-19 Deaths

In stressing the high numbers of additional people who are dying as an indirect result of COVID-19 measures, we may have given the impression that we believe that there would be no additional non-COVID-19 deaths in an unmitigated scenario. We don’t believe that. We aimed to illustrate how the calculator works, and to demonstrate how users can adapt it to their own setting. The key to the tool is that each user is able to adapt it for their own setting.

Disease Forecasting during the COVID-19 Pandemic: Have We Learned from Previous Outbreaks?

Before COVID-19, the 2014-2015 West African Ebola epidemic (EVD epidemic), was one of the most heavily modelled outbreaks in history. Within the first two months of the COVID-19 pandemic, 31 mathematical models were developed. Despite the clear differences in the two outbreaks, the EVD epidemic can help us draw lessons to improve COVID-19 modelling and its reach in policymaking. We discuss some of those learnings in this piece
