Relationship between COVID-19 and orofacial clefts.

The work presents the connection between the infection of COVID-19 during pregnancy and non-syndromic orofacial clefts (NSOFC). Aim of the study was to compare the incidence of COVID-19 disease during mother´s pregnancy between a group of the children with NSOFC and a control group of the children without NSOFC. COVID-19 was confirmed by polymerase chain reaction (PCR) test. The study showed significantly higher incidence of COVID-19 disease in the group of mothers who gave birth to a child with NSOFC in comparison to the group of mothers who gave birth to a child without NSOFC. Our results indicate the possible participation of the infection of COVID-19 in the formation of NSOFCs.
