As of May 18, 2022, the number of coronavirus disease 2019 (COVID-19) confirmed cases has risen to 520,372,492 with 6,270,232 deaths as per World Health Organization. This study sought to determine the significant difference of COVID-19 health status (i.e. asymptomatic, symptomatic) according to age and sex, and the relationship between ABO blood groups (i.e. A, B, AB, O) and said status among qualified residents from Barangay Burol Main, Dasmariñas, Cavite. An informed consent form was distributed. Purposive sampling was used with eligibility requirements posted or attached as an interview checklist. A professionally validated and translated self-made questionnaire was utilized, available as an electronic copy and hard copy, featuring questions about age (i.e. 21- 30, 31-40, 41-50, 51-60), sex (i.e. male, female), and blood type where proof was required for reliability. The health status came from the City Health Office’s official records. There were 103 respondents. Most belonged to the 21-30 age group with 38 (36.9%) with the least as 41-50 having 11 (10.7%). Majority were females with 54 (52.4%). Blood group A was the most common with 41 (39.8%). Most were symptomatic with 64 (62.1%). No significant differences between COVID-19 health status according to age and sex were determined through Chi-Square test for Homogeneity. There was no significant relationship between ABO blood group and COVID-19 health status as per Chi-Square test for Independence. As such, the authors recommended everyone to practice precaution at a maximum level and should be immediately vaccinated since no blood type can yield immunity against COVID-19 manifestation.
