The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to the global outbreak of coronavirus disease 2019 (COVID-19). A newly developed antigen panel detected anti-SARS-CoV-2 antibodies within days of symptom onset, achieving over 90% sensitivity and specificity within the first week. Antibody levels remained elevated in patients who required mechanical ventilation. Despite fluctuations in viral load, antibody levels did not significantly vary over the course of the illness. Interestingly, a high concentration of interleukin-10 (IL-10) was associated with a reduced antibody response, suggesting that this cytokine may play a suppressive role in the humoral immune response to COVID-19.This study also aims to assess the anxiety levels in individuals who did and did not receive the homeopathic remedy Arsenicum album 30 during the COVID-19 pandemic. It compares the mental health outcomes between those who were administered the prophylactic and those who were not. Arsenicum album 30, traditionally known in homeopathy for treating anxiety, restlessness, and heightened sensitivity to health-related fears, is being evaluated for its effectiveness in improving psychological well-being during the pandemic.
