Figure 4. Demographic distribution by age in the Philippines (as of 2018) vs. distribution of Covid-19 cases in the Philippines. Note that only 4% of people in the Philippines are age 65 and above, but 20% of Covid-19 patients are in that group. On the other hand, more than 50% of the population is from 0 to 24 years of age, but they represent only 8% of Covid-19 cases in the Philippines. This discrepancy suggests there is potentially some number of Covid-19 cases that are asymptomatic, mildly symptomatic, or unreported. Based on data from South Korea, the number of asymptomatic cases may be around 30%. This means there could be as many as 9,000 people carrying the SARS-COV2 virus in the Philippines as of April 19, 2020 (versus the actual number of 6,459). Mass testing and tracking of known cases will help give a better estimate of the total number of Covid-19 cases in the Philippines, and mass testing will help identify these silent spreaders.
