While vaccination remains the cornerstone of controlling vaccine-preventive diseases (VPD), little is known about the effect of social distancing on incidence of VPDs. We investigated the impact of social distancing practiced during the coronavirus disease 2019 (COVID-19) pandemic on the incidence of selected VPDs in South Korea. ⋯ The largest decline of total VPDs was in April (65%) and in May (67%), during the intensified social distancing measures. In the setting of sustained vaccination coverage, social distancing may provide additional public health benefit in controlling the VPDs.

Renin-angiotensin-aldosterone system (RAAS) inhibitors, including angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are one of the most prescribed antihypertensive medications. Previous studies showed RAAS inhibitors increase the expression of ACE2, a cellular receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which provokes a concern that the use of ACEI and ARB in hypertensive individuals might lead to increased mortality and severity of coronavirus disease 2019 (COVID-19). To further investigate the effects of ACEI/ARB on COVID-19 patients, we systematically reviewed relevant studies that met predetermined inclusion criteria in search of PubMed, Embase, Cochrane Library databases, medRxiv, and bioRxiv. ⋯ Meta-regression analysis showed that age, gender, study site, Newcastle-Ottawa Scale scores, comorbidities of diabetes, coronary artery disease, chronic kidney disease, or cancer has no significant modulating effect of ACEI/ARB treatment on the mortality of hypertensive COVID-19 patients (all p > .1). In addition, the ACEI/ARB treatment was associated with a lower risk of ventilatory support (OR = 0.682, 95% CI = 0.475-1.978, p = .037, I2 = 0.0%). In conclusion, these results suggest that ACEI/ARB medications should not be discontinued for hypertensive patients in the context of COVID-19 pandemic.

Meta Analysis
Are the steroids a blanket solution for COVID-19? A systematic review and meta-analysis.
Steroids may play a critical role in the current pandemic of coronavirus disease-2019 (COVID-19), given the dearth of specific therapeutic options. This review was conducted to evaluate the impact of glucocorticoid therapy in patients with COVID-19 based on the publications reported to date. A comprehensive screening was conducted using electronic databases up to August 19, 2020. ⋯ Systemic steroid therapy may not be effective for reducing mortality, duration of hospitalization, and period of viral shedding. Studies are mostly heterogeneous. Further RCTs are required.
