Introduction:

COVID-19 has caused millions of deaths around the world since its appearance in Wuhan, China in late 2019. It reached Mexico in early 2020 after it caused many casualties in western Europe. Mexico is now one of the countries with the largest death rate due to COVID-19. Mexico City is not only the largest city in Mexico, but one of the largest in the world. Fortunately, its data regarding COVID-19 patients is publicly available and can be analyzed to obtain information that may guide public policy and personal decisions.

Method:

This work reports the findings of a descriptive study based on data retrieved July 28th, 2020 from the Mexico City government web page that reports suspected COVID-19 patients. Only confirmed cases were analyzed. To calculate the proportion of cases and deaths by age range in Mexico City, the population pyramid of Mexico City was used. To obtain the proportion of cases and deaths relative to population by age range, cases and deaths were adjusted to match those reported by CONACYT. Case and death frequency by gender, age range and previous health condition were calculated using a spreadsheet program. Tables and graphs were obtained using the same program.

Results and discussion:

Age, gender and previous health conditions have an effect in death increase among confirmed COVID-19 patients, so that: older people have a higher mortality rate than younger people, males have a higher mortality rate than females and people with certain previous health conditions such as hypertension and diabetes have a higher mortality rate than people with no previous health conditions. Some examples are regarding the effect of age, COVID-19 patients 61 to 70 years old are twice as likely to die than those 51 to 60 years old; regarding the effect of gender, male patients 51 to 60 years old are more than twice as likely to die than female patients their same age and, regarding the effect of previous health conditions, female patients with hypertension are six times as likely to die than female patients with no previous health condition.

Conclusion:

According to the information available and analyzed in this work, age, gender, and previous health condition are important causes for death rate among COVID-19 patients in Mexico City.
