INTRODUCTION: The NCR had amassed 752,668 cases of COVID-19 as of September 2021, the highest among the regions in the Philippines. This study aimed to determine the correlation between population, population density, age, and sex with the number of cases among local government units (LGU) in the National Capital Region (NCR). METHODS: The data for population, population density, age, and sex distribution of the LGUs of NCR were retrieved from the 2015 Philippine census while the data for cases were from DOH’s COVID-19 Tracker. Pearson correlation coefficient was computed to determine the correlation between population, population density and cases. Phi and Cramer’s V statistic were computed to determine associations between sex, age groups, and cases. RESULTS: There was little or no correlation between population density and number of cases (r = 0.236) but was good (r = 0.905) when Quezon City was excluded for being an outlier. There was good correlation between population and number of cases (r = 964, p < 0.001). There was very weak to no association between sex and number of COVID-19 cases. There was a statistically significant moderate association between age and COVID-19 cases (f = 0.145, p < 0.001). CONCLUSION The study has shown that population density and population have a good correlation with the number of COVID-19 after Quezon City was removed as a data point. There is a moderate association between age and number of COVID-19 cases. There is a very weak to no association between sex and COVID-19 cases.

Background and Objectives: The daily interactions of teachers with students allow the former to observe behavioral changes in the latter. This can serve as an opportunity to emphasize teachers' role in mental health interventions in the school setting. This study aimed to provide baseline information regarding high school teachers' mental health literacy specifically on the recognition and referral of students with depression and suicidal behavior. Methodology: The study design was descriptive cross-sectional that included 460 high school teachers from a district in the City of Manila. The modified QualisMental Vignette Scale for depression literacy and Adolescent Suicide Behavior Questionnaire for suicide literacy was adapted as assessment tools. Results and Conclusion Results of the study found that 64% correctly identified depression as a mental health problem in the modified case vignette. The highest proportion of respondents chose 'informing the parents' as their preferred mode of referral system. The teachers had varying levels of knowledge on suicidal behaviors. More mental health literacy interventions focusing on depression and suicide must be conducted among teachers to improve their competency on these topics.
