ABSTRACT

INTRODUCTION:

As of March 23, 2020, suspension of non-essential activities was declared in Mexico throughout the country in order to mitigate the spread of the COVID-19 pandemic.

OBJECTIVE:

To analyze data on the first 1,510 laboratory-confirmed cases of COVID-19 in Mexico, and to describe the geographical distribution of the disease and its transmission dynamics.

METHOD:

Description of the first COVID-19 cases with real-time RT-PCR-positive test, as well as evaluation of epidemiological measures, cumulative incidence, rate of transmission, and mortality and lethality rates during the first month of the epidemic.

RESULTS:

Average age was 43 years, and 58 % were males; 44 % of initial cases were imported. Lethality in the population during the first month went from 1.08 to 3.97 per 100 cases; however, the trend is linear and similar to that observed in Europe.

CONCLUSIONS:

In Mexico, social distancing is being applied, but studies are still required on the dynamics of the epidemic, person-to-person transmission, incidence of subclinical infections, and patient survival.
RESUMEN

INTRODUCCIÓN:

A partir del 23 de marzo de 2020, en México se declaró la suspensión de actividades no esenciales en todo el país para mitigar la diseminación de la pandemia de COVID-19.

OBJETIVO:

Analizar los datos sobre los primeros 1510 casos de COVID-19 confirmados por laboratorio en México, describir la distribución geográfica de la enfermedad y su dinámica de transmisión.

MÉTODO:

Descripción de los primeros casos de COVID-19 con prueba positiva de RT-PCR en tiempo real, así como evaluación de las medidas epidemiológicas, incidencia acumulada, razón de contagios y tasas de mortalidad y letalidad durante el primer mes de la epidemia.

RESULTADOS:

La edad promedio fue de 43 años y 58 % fue del sexo masculino; 44 % de los casos iniciales fue importado. La letalidad en la población durante el primer mes pasó de 1.08 a 3.97 por 100 casos; sin embargo, la tendencia es lineal y similar a la observada en Europa.

CONCLUSIONES:

En México se está aplicando el distanciamiento social, pero aún se requieren estudios sobre la dinámica de la epidemia, la transmisión de persona a persona, la incidencia de infecciones subclínicas y la supervivencia de los enfermos.
