They explained that their results suggest that the viral charges and the duration of the symptoms are both subjects to change with COVID, which means that the data from the start of the pandemic may not apply yet or in the future.

These results are also not perfectly aligned with the current directives of the Centers for Disease Control and Prevention (CDC), who ask people of " test immediately "When the symptoms appear. However, the agency notes that the PCR tests are more reliable, and if your antigen test is negative, this result is not always correct.
