What Should You Do If You Feel Sick but Keep Testing Negative for COVID? Lancet. The proportion of the children with fever symptoms was 87.2% (526 cases). Abnormal defecation, as a predictor of negative conversion of SARS-CoV-2 RNA and a sensitive indicator of intermittent negative status, is a crucial element in the whole course of disease and even in the recovery period.

The median duration of virus shedding was 12 (interquartile range, IQR: 1014) days. Compared with children aged 06 years, leukocytes counts and lymphocytes counts significantly decreased, and hemoglobin level significantly increased in patients aged 714 years and 1518 years (Supplementary Table 2). The median duration of virus shedding in all patients was 12days (IQR: 914), ranging from 2 to 49days.
