Preventive health in Puducherry
Coastal, monsoon-driven: dengue, leptospirosis and scrub typhus in a compact territory.
What matters most in Puducherry
Dengue
Why here: Stored water in a dense coastal settlement sustains year-round breeding.
What to look for: The day 3–7 phase after the fever settles: belly pain, vomiting, bleeding or sudden collapse.
What to do: Empty and scrub water containers weekly; cover tanks. Paracetamol only — ibuprofen and aspirin worsen bleeding.
Leptospirosis
Why here: Monsoon flooding with rodent contamination.
What to look for: Fever with severe calf pain, red eyes, jaundice.
What to do: Mention wading to the doctor; cover cuts; take doxycycline if offered after exposure.
Scrub typhus
Why here: Post-monsoon mite exposure in the rural fringe.
What to look for: Fever with a painless black scab somewhere on the skin, headache and swollen glands.
What to do: Ask the doctor to look for an eschar in the skin folds. It responds to a cheap antibiotic and is dangerous only when missed.
And everywhere in India
These are not specific to Puducherry, but they cause more illness nationally than anything above, and every one of them is covered free by a national programme.
Tuberculosis
Why here: Still India's deadliest infectious disease, in every state and every income group.
What to look for: A cough lasting more than two weeks, evening fever, night sweats, losing weight without trying.
What to do: Diagnosis and the full drug course are free under the NTEP at any government facility. Stopping early is what creates drug-resistant TB — finish the course.
Snakebite
Why here: One of India's largest causes of accidental death, and heavily rural. Most deaths are delays, not venom.
What to look for: Any bite from an unidentified snake. Drooping eyelids, difficulty swallowing or breathing, or bleeding that will not stop are emergencies.
What to do: Go straight to a government hospital with antivenom. Do not cut, suck, or apply a tourniquet, and do not go to a traditional healer first — that detour is what kills.
Rabies
Why here: Effectively always fatal once symptoms begin, and effectively always preventable before they do.
What to look for: Any bite, scratch or lick on broken skin from a dog, cat, monkey or bat. There is no safe wait-and-see.
What to do: Wash the wound with soap under running water for 15 minutes, then get the vaccine the same day. Free under the NRCP. A wound that looks trivial still counts.
Dengue
Why here: Present in every state and rising with urbanisation; the danger is the crash after the fever breaks.
What to look for: High fever with severe body ache, then — around day 3–7 — belly pain, vomiting, bleeding gums, or sudden exhaustion. That phase is the dangerous one.
What to do: Fluids and paracetamol only. Avoid ibuprofen and aspirin, which worsen bleeding. Empty standing water weekly — the mosquito breeds in clean water at home, not in drains.
