Elsevier established a free COVID-19 resource center in January 2020, offering information in English and Mandarin. The center grants permission for free access to its research in PubMed Central and other repositories. A study published in 2004 evaluated the pregnancy and perinatal outcomes of 12 pregnant women with severe acute respiratory syndrome (SARS) in Hong Kong between February and July 2003. The study found a 25% case fatality rate, with 57% of first-trimester patients experiencing spontaneous miscarriage and 80% of pregnancies after 24 weeks resulting in preterm delivery. No newborns showed clinical SARS, and there was no evidence of perinatal transmission. The study concluded that SARS during pregnancy is associated with high rates of miscarriage, preterm delivery, and intrauterine growth restriction, with no evidence of perinatal infection. The study also noted that SARS poses greater risks to pregnant women compared to non-pregnant individuals. The findings highlight the importance of early intervention and careful monitoring in SARS cases during pregnancy. The study's small sample size limits the generalizability of its conclusions, and further research is needed to better understand the impact of SARS on pregnancy outcomes.Elsevier established a free COVID-19 resource center in January 2020, offering information in English and Mandarin.
