Household transmission of COVID-19 cases associated with SARS-CoV-2 delta variant (B.1.617.2): national case-control study

Hester Allen et al.

Summary: This study indirectly assessed the differences in transmissibility between the SARS-CoV-2 Delta variant and the previously dominant Alpha variant. The results showed that the Delta variant had a higher rate of household transmission, potentially explaining its success in displacing the Alpha variant as the dominant strain in England. Understanding the transmissibility of this variant is important for informing international infection prevention and control policies.

Placental histopathology after SARS-CoV-2 infection in pregnancy: a systematic review and meta-analysis

Raffaella Di Girolamo et al.

Summary: This study aimed to report the spectrum of placental pathology findings in pregnancies complicated by SARS-CoV-2 infection. A significant proportion of placentas in pregnant women with SARS-CoV-2 infection showed histopathologic findings suggestive of placental hypoperfusion and inflammation. Future multicenter prospective blinded studies are needed to correlate these placental lesions with pregnancy outcomes.
