After people were forced to drink stagnant, contaminated water after the Pakistan floods in 2022, waterborne diseases took significant hold. Hundreds of thousands of people reported acute, watery diarrhoea, skin infections, typhoid, malaria, dengue fever and snake bites. Without urgent medical support, these diseases can become fatal, very quickly.
The monsoon season of 2025 has had devastating consequences for many. Since June 2025, 970 people have been killed by flash floods across Pakistan, with more than 1,600 injured. The threat of waterborne diseases spreading at this time is once again of great concern.
Babies and young children are particularly affected by these diseases and the situation can quickly become desperate.
What are waterborne diseases?
Waterborne diseases, such as cholera, typhoid, dysentery and hepatitis A, are caused by microscopic organisms like viruses and bacteria. These organisms can be introduced to the body through contaminated water, or by coming into contact with faeces containing the virus.
Unsafe water and poor sanitation can all increase the spread of waterborne diseases. Without proper medical support, these diseases can cause severe illness and possibly death.

Cholera and other waterborne diseases can be treated by replacing fluids.
Are waterborne diseases affecting people in Pakistan?
Waterborne diseases increase at a faster pace among displaced people in flood-hit areas.
Health officials in Pakistan reported a rise in diarrhoea, skin diseases and eye infections in 2022. Over 90,000 cases of diarrhoea were reported in Sindh in one day, as well as in other heavily affected areas.
The UN children's agency said more than 3 million children stood at heightened risk of diseases, and were in desperate need of clean water and safer living environments.
Why were Pakistan flood victims at increased risk from waterborne disease?
After humanitarian emergencies, such as floods, infrastructure is often destroyed. There's a lack of proper toilets for people living in shelters, public buildings or emergency camps on higher ground. And there's also a lack of handwashing facilities.
This means that diseases like dysentery and cholera can spread very rapidly in overcrowded places.
In terms of fresh drinking water, stored water is frequently contaminated as it is rarely chlorinated and in contact with hands and contaminated cups. In addition, wells could also be contaminated by water from flooded toilets or toilet blocks.
All these factors made the spread of waterborne disease in Pakistan a high and increasing risk.
Does the Red Cross and Red Crescent Movement treat waterborne disease in Pakistan?
Waterborne diseases can be easily treated with oral rehydration salts and IV drips if needed.
However, with so many health facilities affected by the floods, millions of people lack access to healthcare and treatment they desperately need. The World Health Organisation (WHO) recently reported that 888 healthcare facilities were damaged in the Pakistan floods, and 88 completely destroyed.
The Pakistan Red Crescent has mobile health facilities in several affected areas, and are working hard to treat flood victims with waterborne diseases.
Along with agencies such as WHO, the Red Cross and Red Crescent Movement keeps surveillance for waterborne diseases such as acute diarrhoea, and cholera, and providing medical supplies where needed.
Better understand the threat a cholera outbreak poses to the people of Pakistan, by learning about the deadly disease and why it is so common after a natural disaster or conflict.

Could a lack of clean water cause any other problems?
A lack of clean water could affect women in particular. It can be harder to deal with menstruation, especially away from home and without privacy. There's also a potential safety risk for women going to the toilet after nightfall.
Pregnant and breastfeeding women are also at great risk without clean water. Women about to give birth also need clean birth facilities as well as healthcare staff. As many healthcare facilities were destroyed in the floods, the lives of mothers and newborns were at risk.
Help us provide clean water to those affected
- 拢20 could help to provide a hygiene kit containing toothbrushes, soap and toilet paper to one family.
- 拢40 could help to provide ten families with a jerry can so they can store clean water for drinking and cooking.
- 拢65 could help to provide one household with financial support so they can meet their basic needs like buying food and clean drinking water.
