The observational study published in the Journal of Clinical Medicine, researchers interviewed 390 people in Thailand who contracted COVID-19 during the “fifth wave of the COVID-19 pandemic” when the omicron variant was dominant. Patients were followed by phone from three months after their diagnosis for a year to monitor their physical condition, mental health, sleep disturbances, and quality of life.

Out of 390 people with COVID-19, 377 (97 percent) were vaccinated, 383 (98 percent) underwent antiviral treatment, and 330 (78 percent) developed long COVID syndrome. The most frequently reported symptoms were fatigue and cough. Other reported symptoms included depression, anxiety, and poor sleep quality. The study found that patients under age 60 with a cough as an initial symptom were more likely to develop the condition. In a subset of patients with long COVID, researchers found a notable correlation in females with headaches, dizziness, and brain fog.

“Despite the extensive distribution of vaccines and antiviral therapies, the prevalence of long COVID remains high,” the authors of the paper wrote.
