Mexico — humanitarian situation

Mexico faces mounting humanitarian pressures driven by a confluence of natural disasters, public health emergencies, and regional migration dynamics. Tropical Storm Boris made landfall in Guerrero on 9 June 2026, bringing heavy rainfall and life-threatening flooding and mudslides across Guerrero and Oaxaca, resulting in one confirmed death and two missing persons in Colima (OCHA). This event follows severe flooding in late 2025 that affected 320,000 people across 150 municipalities, damaging 100,000 homes, with the Poza Rica and Alamo regions experiencing the most severe impacts (Tzu Chi Foundation). Climate patterns remain concerning, as El Niño threatens continued extreme weather across the region. A measles outbreak has emerged as a critical public health threat across the Americas. Between January and mid-June 2026, the region recorded 22,324 confirmed cases and 38 deaths across 17 countries, representing a 207 percent increase compared to the same period in 2025 (PAHO). Mexico accounts for 11,532 of these cases—52 percent of the regional total and the highest national burden—followed by Guatemala with 6,895 cases (PAHO). The outbreak coincides with reports of broader attacks on health care infrastructure; during 2025, 33 countries globally experienced 2,546 incidents affecting health facilities, resulting in 455 health worker deaths (Insecurity Insight). Mexico's role as a destination and transit country for refugees and migrants continues amid severely constrained humanitarian response capacity. The country processed high numbers of asylum applications throughout 2025 despite historic reductions in humanitarian funding that affected operational capacity (UNHCR). Regionally, the Refugee and Migrant Response Plan secured only approximately 10 percent of required funding in 2025, forcing partners to reduce or suspend activities (R4V). The second half of 2025 saw increasingly restrictive policy environments and heightened security focus across Latin America, contributing to sharp contraction in northbound mixed movements while return dynamics became more prominent (R4V). UNHCR and partners aim to support over 70,000 refugees, asylum seekers, and displaced persons across the Americas through socioeconomic inclusion programming focused on jobs, services, and legal identity (UNHCR).
