Abstract:
COVID-19 initially caused less severe outbreaks in many low- and
middle-income countries (LMIC) compared with many high-income
countries, possibly because of differing demographics,
socioeconomics, surveillance, and policy responses. Here, we
investigate the role of multiple factors on COVID-19 dynamics in
the Philippines, a LMIC that has had a relatively severe COVID-19
outbreak. Methods: We applied an age-structured compartmental
model that incorporated time-varying mobility, testing, and personal
protective behaviors (through a “Minimum Health Standards”
policy, MHS) to represent the first wave of the Philippines COVID-
19 epidemic nationally and for three highly affected regions
(Calabarzon, Central Visayas, and the National Capital Region).
We estimated effects of control measures, key epidemiological
parameters, and interventions. Findings: Population age structure,
contact rates, mobility, testing, and MHS were sufficient to explain
the Philippines epidemic based on the good fit between modelled
and reported cases, hospitalisations, and deaths. The model
indicated that MHS reduced the probability of transmission per
contact by 13-27%. The February 2021 case detection rate was
estimated at ~8%, population recovered at ~9%, and scenario
projections indicated high sensitivity to MHS adherence.
Interpretation: COVID-19 dynamics in the Philippines are driven by
age, contact structure, mobility, and MHS adherence. Continued
compliance with low-cost MHS should help the Philippines control
the epidemic until vaccines are widely distributed, but disease
resurgence may be occurring due to a combination of low
population immunity and detection rates and new variants of
concern. Funding: This work was supported by the World Health
Organization Regional Office for the Western Pacific. Tagalog
