Background:
In 2022, a marked escalation in Monkeypox (Mpox) cases was observed in nonendemic regions, notably South America, despite the virus being traditionally endemic to Central and West Africa. This unexpected shift necessitated a deeper exploration of the novel transmission dynamics, including breastfeeding, given the emerging evidence of potential horizontal and vertical Mpox transmission during mother-infant interactions.
Research Aim:
The study aimed to critically evaluate existing evidence on potential horizontal and vertical Mpox transmission related to breastfeeding and to assess guidelines in South American countries regarding Mpox prevention during breastfeeding.
Methods:
A scoping review and evidence mapping were conducted, adhering to the PRISMA Extension for Scoping Reviews (PRISMA-ScR) guideline. Data extraction involved identifying primary studies evaluating breastfeeding as a transmission route. Additionally, official documents from South American Health Ministries detailing guidelines or policies on breastfeeding in the context of maternal Mpox infection were reviewed.
Results:
Three of 215 studies were found relevant; 2 were case reports, and 1 was a laboratory study. Available evidence suggests that contamination could likely occur horizontally through skin-to-skin contact. Six South American countries had issued guidelines on breastfeeding during Mpox infection, but the guidance varied and was not consistent across the region.
Conclusions:
The study emphasizes the need for clear and consistent guidelines on breastfeeding during Mpox outbreaks, particularly in South America. Collaborative strategies and regular research updates will be essential in addressing the ongoing public health challenge.
