Preventive health in Assam
The paddy-and-piggery landscape of the Brahmaputra valley makes this India's heartland for Japanese encephalitis, and the flood cycle drives everything waterborne.
What matters most in Assam
Japanese encephalitis
Why here: India's heaviest JE burden. Culex mosquitoes breed in flooded paddy; pigs and wading birds amplify the virus, so villages beside both are most exposed.
What to look for: High fever with confusion, a stiff neck, fits, or a child who becomes drowsy and will not wake properly.
What to do: The JE vaccine is in the UIP here — check your children have had it. Fever with confusion is an emergency: go to hospital the same hour, not the next day.
Malaria
Why here: Falciparum malaria persists in the forested and hill districts, where it turns severe faster than the milder vivax form.
What to look for: Fever with chills and sweating, headache; in severe malaria, drowsiness, dark urine or breathlessness.
What to do: Free testing and treatment under NCVBDC. Sleep under the treated net actually issued to you — an untreated net is much weaker protection.
Flood-borne illness
Why here: Annual flooding mixes drinking water with sewage across the valley, driving cholera, typhoid and hepatitis A and E.
What to look for: Watery diarrhoea, especially with vomiting and sunken eyes; jaundice; fever that persists past a week.
What to do: ORS at the first loose stool, not after dehydration sets in. Boil or chlorinate drinking water during and after floods; hepatitis E is particularly dangerous in pregnancy.
And everywhere in India
These are not specific to Assam, 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.
