In some patients, coronavirus (COVID-19) can cause symptoms that last weeks or even months after the infection has gone. The aim of this study was to describe the effect of adjunctive individualized homeopathic treatment delivered to Long-COVID-19 patients with previously confirmed symptomatic SARS-CoV-2 infection.

All patients had been tested positive for SARS-CoV-2 before having developed Long-COVID-19 symptoms. Several testing methods were carried out in each patient to analyze a SARS-CoV-2 infection. For a confirmed infection, at least 3 out of these 5 tests had to be positive. Tests for the orthomyxoviruses influenza A and B, human metapneumovirus (hMPV) and paramyxoviruses were negative unless stated otherwise.

The homeopathic physician treated all Long-COVID-19 patients by individualized homeopathy. Repertorization of the symptoms of the current pandemic and a search in the current homeopathic literature on COVID-19 was performed using computer program. All available homeopathic medicinal products (HMPs) could be chosen by the treating physician.

Modified MONARCH criteria were assessed post hoc by all authors. Deviations were solved by discussion in person. Clinical outcome of case reports was evaluated using the "Modified Naranjo Criteria for Homeopathy-Causal Attribution Inventory". Eight points is assumed as the limit for potential correlation between homeopathic therapy and amelioration of the symptoms or healing in chronic cases.
