Highlights |
• | Peak virus load was identified at 2–3 days after onset with the median of cycle threshold (Ct) value of 16–17 for Omicron BA.2.76 variant infections. |
• | The median range between onset and negative test after the booster dose was shorter than both fully and unfully vaccinated patients. |
• | The range between positive testing and onset is less than a day for Omicron BA.2.76 variant. |
• | Completed full vaccination and received booster reduces the positive duration in n and ORF gene expression. |
