OBJECTIVE:

To describe the associated factors with the degree of severity in pregnant Mexican women reported with SARS-CoV-2 virus infection.

MATERIAL AND METHODS:

Descriptive, transversal and comparative study of free dates reported by Mexico’s Health Secretary of COVID-19 patients until April 26th, 2020. Pregnant women positive to SARS-CoV-2 infection were included. Control group were women in reproductive age. Exclusion criteria were women with puerperal status reported as unknown or does not apply. Infection was analyzed by severity in both groups, then comorbidities associated to degree of severity were determined with descriptive statistic.

RESULTS:

84 pregnant women were positive to SARS-CoV-2 vs 2,836 non-pregnant infected women in reproductive age. 33% of pregnant women required hospitalization vs 17% of control group. 2.4% vs 0.08% required intubation, 3.6% vs 1.3% were admitted to critical care unit and lethality was 7.14% vs 0.7% in pregnant vs control group respectively. Main comorbidities associated with severity in pregnant women were diabetes (50%) and tobacco use (33%).

CONCLUSION:

Pregnant women have greater probability to develop a severe form of SAR-CoV-2 infection compared to women in reproductive age. The main associated factors to severe forms were diabetes and tobacco use.
