Epidemiology of Coronavirus Disease 2019 in Mexico: A Report on Age-Sex Variation in the Duration from Symptom Onset to Fatality as an Outcome in Patients

Abstract

Objective To describe age-sex differences in the duration from symptom onset to fatality as an outcome in coronavirus desease 2019 (COVID-19) patients. Methods The Mexican surveillance system database (up to 15th August 2020) of 70,515 death cases (45,053 males, 25,462 females) in COVID-19 was used for analysis. Age groups for pediatric patients were <1, 1-4, 5-9-years and for the adolescent and adult patients, each decade of life constituted an age group. Results Proportionally more deaths occurred among male patients (64%). Median duration was eight days from onset of symptoms until death; mean value was approximately 10-days. Distribution by age groups showed females survived lower number of average days after the onset of symptoms. A tendency of rise in the number of days survived has been observed from infancy to adulthood and a subsequent decline after 70-years of age. Conclusion Female patients survived relatively lower number of days with infection until death, compared to males.
