Monsoon fevers: preventing dengue and leptospirosis
A little water in a coconut shell is enough for the dengue mosquito. Anyone working in fields or drains must watch for leptospirosis.

Every monsoon, fevers spread across Kerala. Dengue and leptospirosis (eli pani) among them can be life-threatening. Both can largely be prevented.
Dengue
Aedes mosquitoes bite during the day and lay eggs in still, clean water.
- Keep one "dry day" a week: empty every bit of standing water around the house
- Coconut shells, tyres, flower-pot saucers, fridge trays, folds in tarpaulin
- Keep water-storage containers covered
Leptospirosis
The germ enters the body, often through cuts, from water or soil contaminated with the urine of rats, cattle and other animals.
- Farm workers, people cleaning drains, anyone wading through floodwater: wear gloves and boots
- Do not enter dirty water with cuts on your hands or feet
- If your work puts you at risk, ask your nearest health centre about preventive medicine
If you get a fever
- Do not treat it yourself; see a doctor, especially if it lasts more than two days
- Tell the doctor if you have been in contact with dirty water
- Do not take painkillers unless a doctor prescribes them
- Drink plenty of water and kanji water
Go to hospital at once for any of these: vomiting that will not stop, severe stomach pain, bleeding from the gums or nose, yellow eyes, or passing very little urine.
