In November, MSF emergency response teams in Mexico City and the states of Mexico, Puebla, Oaxaca and Morelos completed the medical, mental health and health promotion activities launched after the two major earthquakes in September. In the days following the seismic movement on 19 September, our teams in Puebla identified respiratory problems, aggravations of chronic diseases such as hypertension and diabetes, and psychosomatic symptoms as the main medical conditions affecting the population. In Oaxaca state, which was heavily affected by the earthquakes, teams provided medical care, mental healthcare and carried out health promotion activities, while training key people in the community. We gave psychological first aid training to strategic health personnel, volunteers, community leaders, and community teachers, mainly in the state's Juchitán region. At the end of October, we completed our response to the needs for emotional stabilisation and mental healthcare in San Miguel Tecomatlán, in Mexico state, and Xochimilco, in Mexico City. In Jojutla, in Morelos state, we focused on providing psychological first aid training to health jurisdiction personnel, mental health promoters, teachers and community leaders. We also trained members of the medical emergency unit's new team.
