The most critical resources for a hospital facing a cholera surge are, overwhelmingly, the supplies and personnel for rapid rehydration. This includes vast quantities of Oral Rehydration Salts (ORS) and Intravenous (IV) fluids (like Ringer's Lactate), which are the direct, life-saving treatments. Coupled with this is the need for sufficient trained staff, especially nurses, to administer these fluids and monitor patients continuously.
For severe outbreaks, specialized facilities known as Cholera Treatment Centers (CTCs) are often established. These are temporary, self-contained units designed exclusively for cholera care, featuring strict zones for patient triage, treatment, and waste management to perfectly control infection. The essential equipment for these facilities extends beyond medical supplies to include robust sanitation infrastructure: large quantities of chlorine for disinfection, personal protective equipment (PPE) for staff, safe water tanks, and dedicated latrines to safely manage the high volume of infectious waste.
