Discussion

Cross-sectional study examines vitamin D levels and SARS-CoV-2 infection rates in ethnic populations, suggesting significant links.

Vitamin D deficiency was prevalent, affecting 25% of Black and 21% of Asian patients, underscoring ethnic disparities.
Among 485 SARS-CoV-2 positive patients, a median 25(OH)D level of 42 nmol/L was observed, indicating high deficiency rates.
Age and BMI were significant infection factors, particularly noted in White and Black patients respectively, guiding future monitoring.
Findings highlight the need for addressing vitamin D deficiency to potentially improve immune function against respiratory infections.

Sobczyńska‐Malefora et al. (2025) studied this question.
