Abstract
OBJECTIVE: To investigate morbidity and mortality rates from severe acute respiratory syndrome in pregnant women and newborns in the first two years of the COVID-19 pandemic. METHODS: This was a descriptive-analytical study in which data on cases and deaths in pregnant women and newborns with a positive diagnosis of severe acute respiratory syndrome, regardless of the etiological agent, were collected from the Influenza Epidemiological Surveillance Information System and data on the number of live births from the Live Birth Information System. The frequencies of cases and deaths and the morbidity and mortality rates among pregnant women and newborns in the state of Rio de Janeiro were calculated using the Kruskal-Wallis test to compare the periods 2018-2019 and 2020-2021. RESULTS: During the pandemic, there was a statistically significant increase in morbidity rates in pregnant women (24.49/100,000 to 537.39/100,000; p-value<0.001) and newborns (69.97/100,000 to 200.82/100,000; p-value 0.022) and mortality rates in pregnant women (1.87/100,000 to 48.08/100,000; p-value<0.001) and newborns (1.87/100,000 to 9.26/100,000; p-value 0.008). CONCLUSION: This study identified a statistically significant increase in morbidity and mortality rates due to severe acute respiratory syndrome in pregnant women and newborns in the state of Rio de Janeiro during the pandemic. There is a clear need for greater investment to reduce harm to these groups, such as vaccination and access to the healthcare system, as well as highly complex infrastructure throughout the state.
