Risk factors for long COVID syndrome in postmenopausal women with previously reported diagnosis of COVID-19.

Purpose: Long COVID-19 syndrome occurs in 10-20 % of people after a confirmed/probable SARS-COV-2 infection; new symptoms begin within three months of COVID-19 diagnosis and last > 8 weeks.
