Preventing and managing waterborne illness at home
How to recognise, prevent and safely manage common waterborne illnesses in Nepal — diarrhoea, cholera, typhoid and hepatitis — including how to make and give ORS, spot dehydration danger signs, and know when to rush to a clinic.
Waterborne illnesses are among the most common health problems in Nepal, especially in the monsoon and in places with unsafe water or sanitation. Most are caused by germs that enter the body through contaminated water or food: diarrhoeal disease, cholera, typhoid and hepatitis A and E (jaundice) are the big ones, and they hit children, older people and pregnant women hardest.
The most important thing to understand is that diarrhoea itself is rarely what kills — dehydration is. Losing too much fluid, fast, is the real danger, and it is also the part you can treat at home with oral rehydration salts (ORS). Knowing how to give fluids and how to spot the danger signs that mean 'go to a clinic now' can save a life.
This guide covers the practical essentials: how these illnesses spread and how to prevent them, how to recognise them, how to make and give ORS correctly, what to do (and not do), and exactly when home care is no longer enough.
The common waterborne illnesses in Nepal
Several illnesses share the same root cause — contaminated water and food — but show up differently. You do not need to diagnose precisely at home; the point is to prevent them, treat dehydration, and get medical help when the signs are serious.
Prevention is the same for all of them and is covered in detail in the safe-water, water-storage and sanitation guides: treat your water, store it safely, wash hands with soap, and handle food hygienically.
- Acute diarrhoea: frequent loose or watery stools; the most common, and most cases can be managed at home with fluids if there are no danger signs.
- Cholera: sudden, profuse watery diarrhoea (often 'rice-water' in appearance) that can dehydrate dangerously fast — a medical emergency, especially in outbreaks.
- Typhoid (enteric fever): prolonged high fever, headache, stomach pain, weakness — needs a doctor's diagnosis and antibiotics.
- Hepatitis A and E (jaundice): tiredness, loss of appetite, nausea, dark urine and yellowing of the eyes/skin — see a doctor; hepatitis E is particularly risky in pregnancy.
- Worm and parasitic infections: from contaminated water, soil or food; often need specific deworming treatment.
Prevent illness in the first place
Almost all of these illnesses are preventable with the same handful of habits. Doing them consistently — not just when there is an outbreak — is what keeps a household healthy through the year and especially through the monsoon.
- Treat all drinking and cooking water (boil, chlorinate, filter-and-disinfect, or SODIS).
- Store treated water in clean, covered containers and never dip hands or used cups inside.
- Wash hands with soap after the toilet, after cleaning a child, and before cooking and eating.
- Eat food cooked thoroughly and served hot; wash raw fruit and vegetables in safe water; keep flies off food.
- Use and maintain a clean toilet, and keep waste and pits away from water sources.
- Ask your health post about vaccines where relevant (for example, typhoid and hepatitis A vaccines are available) and routine child immunisation and deworming.
ORS first: rehydration is the priority
For diarrhoea (and the vomiting and diarrhoea of cholera), replacing lost fluid and salts is the single most important treatment. Oral rehydration salts (ORS), called jeevan jal in Nepal, are cheap, sold at every pharmacy and many shops, and save lives. Start ORS early, at the first loose stools — do not wait for the person to look unwell.
Give ORS after every loose stool and after vomiting, in small frequent sips even if the person is vomiting (small amounts are kept down better). Keep going until the diarrhoea stops. For young children, doctors also recommend zinc supplements for diarrhoea — ask your pharmacy or health post.
- Buy ready-made ORS sachets if you can — they have the correct, safe balance of salt and sugar.
- Mix one sachet in the exact amount of clean, safe (treated) water stated on the packet — not more, not less.
- Give frequent small sips: a spoonful every few minutes for a small child, more for an adult; offer ORS after each loose stool/vomit.
- Keep breastfeeding babies and keep giving normal food to children once they can eat — do not starve them.
- Make a fresh batch each day and discard leftover mixed ORS after about 24 hours.
Homemade rehydration drink (only if no ORS sachet)
If you genuinely cannot get an ORS sachet, you can make a basic rehydration drink at home, but the amounts matter — too much salt is harmful, especially for children. Use level measures and safe water.
Treat this as a stopgap until you can get proper ORS, not a long-term substitute. If you are unsure of the measures, plain safe water, rice water (the water from cooking rice), soups and continued breastfeeding are safer than a wrongly-mixed salt-sugar drink.
- Mix in 1 litre of clean, safe water: about six level teaspoons of sugar and half a level teaspoon of salt.
- Stir until dissolved; it should taste no saltier than tears — if it is very salty, throw it out and remake it.
- Never add extra salt, and do not use this as a substitute for proper ORS for a seriously ill person.
- Avoid sugary fizzy drinks and very sweet juices as the main fluid — they can worsen diarrhoea.
Danger signs — when to go to a clinic now
Home care with fluids is enough for most simple diarrhoea, but some signs mean the person needs medical care urgently — do not wait, and do not rely on home remedies. Be especially quick with babies, young children, the elderly and pregnant women, who dehydrate and deteriorate fast.
If you see any of the danger signs below, get to a health post, clinic or hospital immediately. During a suspected cholera outbreak, treat profuse watery diarrhoea as an emergency from the start.
- Signs of dehydration: sunken eyes, very little or no urine, dry mouth, no tears, lethargy or floppiness, or skin that stays pinched.
- Cannot keep any fluids down due to constant vomiting.
- Blood in the stool, or persistent high fever.
- Very frequent, large watery stools (especially 'rice-water' stools — possible cholera).
- Diarrhoea lasting more than a couple of days, or any serious illness in a baby, elderly or pregnant person.
- Signs of jaundice (yellow eyes/skin, dark urine) — see a doctor; do not self-treat.
Things to avoid and what to do during an outbreak
Some common reactions actually make things worse. Avoid them, and lean on fluids, food and timely medical care instead.
If there is a diarrhoea or cholera outbreak in your area, be extra strict with water treatment and handwashing, keep the sick person's stool and vomit safely contained and disinfected, and report cases and seek care early — outbreaks can spread through a community fast.
- Do not stop fluids or food to 'rest the stomach' — that worsens dehydration and slows recovery.
- Do not take antibiotics or 'stopping' (anti-motility) medicines on your own — get a doctor's advice; the wrong drug can be harmful, especially for children.
- Do not rely only on home or herbal remedies for a severely ill person — give ORS and get medical help.
- During an outbreak: treat all water, wash hands strictly, disinfect the sick person's waste and surfaces, and seek care for the sick early.
- Keep ORS sachets and the means to treat water at home all through the monsoon so you are ready before illness strikes.

Diarrhoea, Cholera & Typhoid — FAQ
What exactly is ORS / jeevan jal and where do I get it?+
ORS (oral rehydration salts) is a precise mix of salt, sugar and minerals that replaces the fluid and salts lost in diarrhoea and vomiting. In Nepal it is widely sold as jeevan jal in ready-made sachets at pharmacies and shops and is very cheap. Mix one sachet in the exact amount of clean, safe water printed on the packet.
My child has diarrhoea but is otherwise alert — do I need a doctor?+
If the child is alert, drinking ORS, passing urine and has no blood in the stool or high fever, you can usually manage at home with ORS, zinc and continued feeding. Watch closely and go to a clinic if any danger sign appears — sunken eyes, no urine, constant vomiting, lethargy, blood in stool or fever — or if it does not improve in a day or two.
Can I give my child anti-diarrhoea medicine to stop it quickly?+
No, not on your own. Anti-motility 'stopping' medicines are generally not recommended for children and can be harmful, and antibiotics are only needed for specific infections diagnosed by a doctor. The right home treatment is fluids (ORS), zinc for children, and continued feeding; see a doctor for medicines.
Is there a vaccine against typhoid or cholera?+
Vaccines exist for typhoid and hepatitis A, and cholera vaccines are used in some outbreak settings. Availability varies — ask your health post, doctor or a travel/vaccination clinic about what is appropriate for you. Vaccines reduce risk but do not replace safe water, food and hygiene.
Why is jaundice (hepatitis) dangerous in the monsoon?+
Hepatitis A and E spread through contaminated water and food, which is more common when floods contaminate supplies in the monsoon. Hepatitis E is especially serious in pregnant women. If someone has yellow eyes/skin, dark urine, tiredness and nausea, see a doctor rather than self-treating, and be strict about treating all drinking water.
