Criteria proposed for vertical transmission of SARS-CoV-2
The virus should be found in the placenta and the baby must test positive for the virus within three days of birth, experts say
Specific testing for SARS-CoV-2 within three days of birth and examination of placental tissue is necessary to confirm vertical transmission of the virus from infected pregnant mothers to their offspring, researchers say.
The international team propose that the diagnosis of early-onset neonatal COVID-19 infection be limited to neonates with positive real time-PCR testing for SARS-CoV-2 within the initial 72 hours of life.
