We see the water rise, roll up our sleeves, and walk on. But that water is far from clean—mixed with sewage, waste, oil, and germs. Every step carries risk. A tiny cut, a scratch you barely notice, and harm can enter your body. I tremble thinking how easily sickness finds those who feel safe.

Each rainy season, patients come to our clinic, pale and feverish, saying, “Doctor, I only walked through floodwater.” They never imagined it could make them this ill. I see the suffering firsthand, and fear grips me—that simple, daily walks may lead to sickness no one saw coming.

Storms bring fiercer hangin and sudden, rushing floods. The climate we knew is slipping away, rhythms we trusted fading fast. This scares me most—because as the weather changes, so do the risks. We must be more careful than ever.
