Nepal Floods Raise Concerns Over Infectious Disease Risks
Nepal has been hit by a powerful flood near the Nepal-Tibet border.
The flood carried water, ice, rocks and debris into areas where people live.
Homes, roads and bridges were damaged, and many people died or are missing.
Rescue workers are still looking for survivors.
Floodwater can contain germs, sewage, animal waste and chemicals.
These dangers can make people sick if they drink the water, eat contaminated food or touch it through cuts.
People should use bottled, boiled or treated water and stay away from floodwater.
They should wash their hands, cover wounds and throw away food touched by floodwater.
Anyone who becomes seriously or persistently ill should contact a healthcare professional.
A sudden flash flood struck Nepal near the Nepal-Tibet border on August 26, reportedly after part of a Himalayan glacier collapsed.
Floodwater destroyed homes, roads and bridges, while many people were killed or remain missing.
Sewage, human and animal waste, chemicals and debris in floodwater can spread infections and cause injuries.
Potential health threats include diarrhoeal illnesses, typhoid, hepatitis A, skin infections, leptospirosis and tetanus.
People should avoid floodwater, use safe water, protect wounds, wash hands and seek care for persistent or severe symptoms.
