Pan et al. report a family cluster where a mother and child were both asymptomatic but had positive RT-PCR results. Hoehl et al. 2020 report that two of the 114 Germans who were evacuated from Hubei province on 1 Feb 2020 tested positive in two throat swab specimens by RT-PCR; both did not show any symptoms. The patients were isolated in a hospital in Frankfurt, and a faint rash and minimal pharyngitis were observed in one patient. Seven days after admission, both patients were still well and afebrile. Potential infectivity was confirmed by virus culture.
