On April 18, 2020, the author wrote an Open Letter to Philippine President Rodrigo R. Duterte on “World Experience and New Scientific Findings: Relevance for Containing COVID-19”. That Open Letter promised President Duterte that the points made by the Open Letter would be substantiated in a more comprehensive Briefing Paper. This is that Briefing Paper. Our research team2 took a look at the available date from official government sources, including the Department of Health (DOH). We also supplemented it with data from Worldometer, which, in turn, gets its data from the World Health Organization (WHO). In addition, for four weeks, daily, we followed news stories and scientific articles in dozens of varied sources available on the Internet.
We began our research with no preconceived notion of what position to take on the COVID-19 pandemic. We just wanted to learn what was going on. In the course of our research, however, we started seeing that the weight of scientific evidence called for a more nuanced approach to dealing with the pandemic, instead of a total lockdown. We wanted to advocate an approach that saves both lives and society, including its economy, at the same time. We thus relayed this new understanding and approach to President Rodrigo Roa Duterte of the Philippines in an Open Letter. This Briefing Paper is an attachment to that Open Letter.
This Briefing Paper gives the evidence for embarking on a more nuanced approach to controlling COVID-19. We call this approach the Precision Quarantine and Immunity
(PQI) approach. Although we are dealing with COVID-19 as it is manifesting in the Philippines, we think our experience here is relevant to other countries, just as the global experience has been important for us and the Philippines.
A substantial portion of this Briefing Paper refers to experiences, scientific findings, and
perspectives from all over the world. So those, anywhere in the world, wanting to gain a sense of these perspectives may also benefit from the synthesis of data and perspectives that we have integrated together in this Briefing Paper. You can access a copy of the Open Letter and Briefing Paper at
