Gestação, COVID-19, Transmissão vertical.Abstract
A doença nomeada COVID-19 pela Organização Mundial da Saúde, foi declarada pandemia em 11 de Março de 2020. Preocupa-se que haja possibilidade de transmissão vertical devido à alta infectividade do SARS-CoV-2 e a reconhecida imunossupressão gestacional. Assim, o objetivo do presente estudo foi revisar as evidências científicas sobre a possibilidade de transmissão vertical na COVID-19. Foi realizada uma revisão integrativa nas bases de dados PubMed, Lilacs, Science Direct e Scielo por meio dos descritores “pregnancy” e “COVID-19” até 14 de junho de 2020, selecionando aqueles que abordassem transmissão vertical. Dentre os 23 artigos escolhidos, observou-se que o risco de transmissão materno-fetal é plausível – já que poucos artigos relatam presença do vírus em tecido placentário – mas parece incomum. É possível que o vírus seja encontrado em menor proporção na nasofaringe do neonato, todavia, análises do líquido amniótico, sangue do cordão umbilical e leite materno não evidenciaram presença viral, até o momento.
