COVID-19 Susceptibility, Mortality, and Length of hospitalization based on age-sex composition: Evidence from Davao Region Philippines

The coronavirus disease is spreading continuously worldwide with an unprecedented amount of impact on every human society. In order to reduce the risks of infections and mortality, several interventions such as mobility restrictions for different age groups and vaccination prioritization programs are implemented in the Philippines. Identifying age-sex composition with greater susceptibility, longer hospitalization, and higher fatality is useful to guide the targeted intervention and establish risk stratification for patients infected with COVID-19 within communities and localities. Furthermore, it is also helpful in the allocation of medical resources and assessment of vaccination priority. We analyzed the COVID-19 data provided by the Davao Center for Health Development of the Department of Health Davao Region in the Philippines. The dataset contains records of COVID-19 cases reported from March 2020 to April 2021. Methods that were used include descriptive statistics, graphical presentations, and nonparametric statistical methods. The study reveals that male children and female senior citizens are the most susceptible age-sex composition while male senior citizen is the subgroup with the highest case fatality and mortality. Furthermore, regardless of sex groups, the senior citizen is the subgroup with the longest hospitalization. Susceptibility due to exposure should be included as a criterion in determining the age-sex compositions for vaccination priority against COVID-19 and other potentially deadly viruses. Further, Proper planning and allocation of medical resources for the elderly should be prioritized in the provincial levels.
