ABSTRACT
INTRODUCTION: SARS-CoV-2 continues to have a high rate of contagion worldwide. The new variant of concern, Omicron, has mutations that decrease the effectiveness of vaccines and evade antibodies from previous infections resulting in a fourth wave of the pandemic. It was identified in Mexico in December 2021. METHODS: The Traveler's Preventive Care Clinic from the Faculty of Medicine UNAM at Mexico City International Airport has performed rapid antigen and PCR SARS CoV2 tests since January 2021 to comply with the new travel requirements. Demographic and clinical characteristics were collected from each passenger and the fourth wave of the pandemic in Mexico mainly caused by Omicron was analyzed in the travelers. RESULTS: A total of 5176 travelers attended the clinic between the second half of December 2021 and January 2022. Ten percent of all the tests performed were positive (13% of PCR and 9.3% of antigens, p = 0.001). Most of the SARS CoV2 positive cases were asymptomatic (78%), with a ratio of 3.5:1 over the symptomatic. By age groups, this ratio was higher for those under 20 years old (8.7:1). DISCUSSION: This study shows the rapid escalation of positivity that occurred in Mexico, detected in travelers, from the second half of December 2020 and throughout the month of January 2021. The incidence of COVID-19 was extremely high in travelers who were mostly asymptomatic for the period under study.

Resumen: Objetivo: Revisar los aspectos epidemiológicos de la enfermedad diarreica aguda (EDA) a través de la historia de México y analizar las estrategias que potencialmente podrán prevenir su aparición en la población mexicana. Material y métodos: Se realizó una búsqueda sistematizada utilizando los siguientes descriptores de las ciencias de la salud: diarrea, morbilidad, mortalidad, México y promoción de la salud de los últimos 20 años (1878-2018). Resultados: Se obtuvieron más de 8 600 artículos que fueron evaluados en función de los objetivos de la presente publicación. Conclusión: Como resultado de una revisión sistemática se observó que, gracias a las estrategias implementadas a lo largo del tiempo, se ha logrado graduar los matices de riesgo de la EDA; ello permite ahora plantear estrategias que guiarán a la prevención de ese padecimiento, de la mano de políticas que incluyan aspectos higiénico-dietéticos, innovaciones farmacéuticas y aplicaciones tecnológicas en medidas sanitarias.
Abstract: Objective: To analyze the epidemiological aspects of AID through Mexican history and the potential strategies to prevent AID in Mexican population. Materials and methods: A systematic review was performed exploring the key words, diarrhea, morbidity, mortality, Mexico, health promotion for the last 20 years (1978-2018). Results: Over 8 600 articles were obtained; all of them were evaluated to consider those follow the aim of the present work. Conclusion: The result of the performed systematic review denoted the influence of AID in Mexican public health policy the adopted actions diminished the AID's associated risks and allowed future strategies to prevent it; those actions must include hygienic and dietetic measures, pharmaceutical innovations and technological tools applied to health policies.
