WHO says the true global burden is likely higher because many cases go unreported.

Why early care matters

Cholera spreads through contaminated food or water and can cause dangerous dehydration. WHO says more than one in five reported deaths happened outside health facilities, highlighting barriers to timely treatment.

The organisation calls for investment in safe water, sanitation, vaccination, surveillance and access to care. The figures concern global reports for 2025; check local health authorities for current conditions in Malaysia or your travel destination.

When to seek help

If you suspect cholera, seek medical attention immediately. CDC advises starting oral rehydration solution promptly while obtaining care. This article provides general information.
