Study: Lingering cough, fatigue more common in Omicron patients

Patients suffering from COVID-19 aftereffects were more likely to have persistent coughs and fatigue if they were infected with the Omicron variant instead of the Delta or other strains, a survey showed. The survey by the Tokyo metropolitan government was based largely on data collected from eight hospitals run by the metropolitan government or the Tokyo Metropolitan Health and Hospitals Corporation. These hospitals offer telephone consultations to patients experiencing long-term effects of COVID-19. The Tokyo Center for Infectious Disease Control and Prevention analyzed consultation records for 2,039 patients who tested positive for the Omicron variant between January and April.
