- [Okayama University] Utility of Viral Antibody Titer Measurement in Long COVID Care during the Omicron Period ~Brain Fog Symptoms and Decreased QOL Associated with Antibody Titers~
- A research group at Okayama University analyzed blood viral antibody titers in 275 long COVID patients infected during the Omicron variant period. They found that brain fog symptoms and decreased quality of life (QOL) were associated with low anti-spike (S) antibody levels, while anti-nucleocapsid (N) antibodies were high in females and severe cases at the time of infection. This research is expected to be useful for objective evaluation and prognosis prediction of long COVID.
