The Department of Medical Sciences lists 8 flood-linked risks: respiratory infections, food and waterborne illness, leptospirosis, fungal foot infections and wounds, pink eye, dengue, electrical, drowning and animal-bite accidents, and flood stress. For a small business, this means protecting staff who wade through flooded areas: boots, washing feet with soap, cooking food thoroughly, and cutting power at the breaker before water reaches the premises. Staff with fever after flood exposure, or with jaundice, bloody-red eyes or swollen infected wounds, should see a doctor promptly. Plan for absences and keep a first-aid kit ready.
