Table 2. Characteristics of studies related to MERS-CoV.

MERS-CoV	Author/year	Study population	Study design and intervention	Outcome measures	Conclusions
	Assiri et al., 2016 16	n=5 pregnant women.	Case report	Two patients died, two cases resulted in perinatal death, one pregnancy led to intrauterine fetal demise, and one infant died after an emergency cesarean section.	MERS-CoV may pose serious health risks to both mothers and infants during pregnancy.
	Alfaraj et al., 2019 17	n=2 pregnant women.	Case report	Both patients did not deliver during hospitalization and subsequently delivered a healthy infant at term.	The outcome was favorable in most pregnancies associated with MERS-CoV cases.
	Jeong et al., 2017 18	n=1 39-year-old pregnant woman.	Case report	Benign maternal course that resulted in full recovery with subsequent healthy full-term delivery.	Further studies with a larger sample size will expand the knowledge of pathophysiology and perinatal outcome.
	Alserehi et al., 2016 19	n=1 33-year-old pregnant woman.	Case report	Preterm delivery of a male infant without complications.	The pregnancy had a favorable outcome for the newborn.
	Malik et al., 2016 20	n=1 32-year-old woman.	Case report	Preterm delivery of a male infant without complications. The mother presented a progressive worsening of clinical status, leading to death.	MERS-CoV infection and pregnancy were a fatal combination in this case.
	Park et al., 2016 21	n=1 39-year-old woman.	Case report	Placental abruption; urgent C-section.	The pregnancy had a favorable outcome for both mother and newborn.
	Payne, 2014 22	n=1 39-year-old pregnant woman.	Case report	Second-trimester stillbirth in a pregnant woman with MERS-CoV infection.	MERS-CoV infection during pregnancy may pose serious health risks to both mother and fetus.
