Background: Brazil has had one of the highest numbers of cases and deaths from coronavirus disease 2019 (COVID-19) worldwide. Objectives: This study aimed to investigate the association between COVID-19 influenza-like symptoms and the use of a homeopathic medicine Bryonia alba 30cH, China officinalis 30cH and Metallum album 30cH during the pandemic in Brazil. Methodology: An observational, longitudinal, cohort study was conducted in Duque de Caxias, Rio de Janeiro, from May to June 2020. Participants were divided into two groups with or without COVID-19 influenza-like symptoms, who received the homeopathic medicine. The primary endpoint was the number of COVID-19 influenza-like symptoms. Secondary measures were the number of hospital admissions, adverse events, and improvements in general health symptoms reported by the participants. Results: Data from 51 families (128 participants) were analysed and showed no statistically significant difference in the severity of illness in the previously sick and healthy groups (p < 0.05). Although, secondary outcome showed that a high percentage of participants (98.03%) reported having had general health symptoms' improvements (84.31%) and none reported adverse events. Despite the previous comorbidities in 52.9% of the families and considering that COVID-19 infected 1.96%, only 0.098% sought for medical assistance and none needed hospitalisation. Conclusions: no differences were found between the previous sick and healthy groups after homeopathy intervention. However, data showed that homeopathic medicine was safe and promoted improvements in general health symptoms. Results reinforce the need for further randomised controlled trials, in the knowledge that homeopathy may offer a health promotion during epidemics.
