How to obtain evidence of vertical transmission of coronavirus according to serological test of specific IgM and IgG antibodies / 中华围产医学杂志

ABSTRACT

Whether 2019 novel coronavirus can be vertically transmitted to fetuses is a major concern, while how to obtain evidence of vertical transmission in viral infected pregnant women is the key. Virological and serological evidence is valuable to clarify this issue. However, longitudinal follow-up of infants for at least 3-6 months after birth and dynamic changes of specific antibodies of the mothers is essential when serological results are used to confirm or exclude vertical transmission.
