Dynamic profiles of SARS-Cov-2 infection from five Chinese family clusters in the early stage of the COVID-19 pandemic

Abstract

Although several cases of family clusters with SARS-Cov-2 infection have been reported, there are still limited data preventing conclusions from being drawn regarding the characteristics and laboratory findings in the COVID-19 population within family clusters. In the present study, we retrospectively collected five family clusters with COVID-19 and summarized the dynamic profiles of the clinical characteristics, laboratory findings, immune markers, treatment and prognosis of this population. Furthermore, we also compared clinical and laboratory data between the SARS-Cov-2 infection with family cluster (n = 21) and those without family cluster (n = 16). We demonstrated that the duration of SARS-Cov-2 replication might be varied based on the different family clusters due to their different genetic backgrounds. The onset improved lung radiology might start at the end of the SARS-Cov-2 positive period. Furthermore, the obtained results demonstrated that similar basic characteristics and clinical findings seem to exist between the cases with SARS-Cov-2 and without family clusters. The serum level of ferritin might have a different biological function and be a new biomarker for the family cluster. Further studies with larger numbers of patients are required.

Correlation of hematological parameters and cycle threshold in ambulatory patients with SARS‐CoV‐2 infection

“…The dynamics of SARS‐CoV‐2 infection is linked to Ct value; a low Ct value is associated with a high risk of severe infection, while a high Ct value is associated with a mild infection 32‐34 . Hematological parameters may be colinked to the Ct value, since for patients with severe infections, the values of total WBC, as well as parameters of the RBC series (mean corpuscular volume, mean corpuscular hemoglobin, hemoglobin), were decreased; on the other hand, in patients with mild or asymptomatic infections, these parameters increase 35,36 .…”
