The Justice Jose Abad Santos General Hospital, a city-run facility in Manila, issued a public advisory Monday warning of critical overcrowding in its emergency department. The ER has reached 300 percent capacity as a continuous stream of patients—both suspected and confirmed leptospirosis cases—seeks treatment following the recent weather events that inundated the metropolis.

Leptospirosis, a bacterial infection transmitted through contaminated water and commonly spread during floods, has emerged as a significant public health concern for Manila residents. The surge in cases reflects broader vulnerability across the city's urban poor communities, where flooding frequently creates conditions conducive to disease transmission.

The hospital's advisory underscores the strain placed on healthcare infrastructure when severe weather compounds existing disease pressures. City authorities have not yet announced additional measures to address the capacity crisis or control the disease spread, though public health officials typically recommend avoiding floodwaters and seeking prompt medical attention for symptoms including fever, headache, and muscle pain.

The situation highlights persistent challenges facing Manila's healthcare system during the monsoon season, when heavy rainfall regularly triggers flooding across the city's low-lying areas and informal settlements. Hospital administrators are managing the influx while continuing to treat patients across all departments.
