CIDRAP –
A new study based on COVID-19 patients in France shows high reinfection rates among people with different Omicron subvariants, including BA.1, BA.2, and BA.5. The study is published as a research letter in Emerging Infectious Diseases. The research group conducting this study, from Aix Marseille University, previously found reinfection rates were 6-fold higher during the Omicron surge than in previous variant surges. In this study, the authors used a computerized alert system that identified positive case samples with primary Omicron BA.1 or BA.2 subvariant infections followed by reinfection with any Omicron subvariant.
