Abstract

• Asymptomatic carriers (RT-PCR+ and serum IgG+) are unable to transmit virus. • Such a low transmission risk might be partly associated with high Ct values. • A new pattern in SARS-CoV-2 infected patients might have emerged.

摘要

• 无症状感染者(RT-PCR 阳性且血清 IgG 阳性)无法传播病毒。 • 如此低的传播风险可能部分与高 Ct 值有关。 • SARS-CoV-2 感染患者可能出现了新的模式。
