MERS-CoV
Pregnant women with symptomatic MERS-CoV infection may be at a higher risk of adverse events. There are 9 reported cases of symptomatic MERS-CoV in pregnant women, and 7 of them required ICU admission, 5 required mechanical ventilation, and 3 died (Table 8).138 One case report of a term delivery in a recovered patient and another report of a patient delivered preterm while in the active phase of infection showed negative viral testing in the infant.138 , 139 There are 2 reported cases of asymptomatic MERS-CoV infection in pregnant women, both identified via contact tracing. One was identified at 6 weeks gestation, and the other at 24 weeks. Both had healthy term deliveries.140 Based on available epidemiologic data, it is unclear whether pregnant women with MERS-CoV have worse outcomes, though 3 deaths among eleven reported cases are concerning compared to an 8.9% death rate reported in a nonpregnant female population.141
