Railway Board
Apex body under the Ministry of Railways that frames policy and manages Indian Railways; its Chairman is ex-officio Principal Secretary in the Ministry of Railways.
Ayushman Bharat PM-JAY
National health assurance scheme launched in 2018 providing secondary and tertiary hospitalisation cover of Rs 5 lakh per family per year to eligible poor households.
Simple interest formula
Interest equals principal multiplied by rate multiplied by time, divided by 100; used when interest is computed only on the original principal.
Combined mean formula
For two groups of sizes n1 and n2 with means m1 and m2, the combined mean is (n1·m1 + n2·m2) divided by (n1 + n2).
Alphabet reverse position
The reverse alphabet position of a letter equals 27 minus its forward position; thus A is 26 and Z is 1 in reverse order.
Syllogism validity rule
A conclusion follows only if it is true in every possible Venn diagram consistent with the premises; a single counter-diagram invalidates it.
Plasmodium life cycle
Sporozoites from a mosquito enter liver cells, mature to merozoites that invade red cells, and gametocytes are taken up by the next feeding mosquito.
Active versus passive immunity
Active immunity develops after infection or vaccination and is long-lasting; passive immunity uses ready-made antibodies and gives immediate but temporary protection.
PM2.5
Airborne particulate matter with aerodynamic diameter of 2.5 micrometres or less; it penetrates deep into alveoli and carries the greatest health risk.
Biochemical oxygen demand
BOD measures the oxygen consumed by microorganisms decomposing organic matter in water; a high value indicates heavy organic pollution.
Incidence versus prevalence
Incidence counts new cases per population at risk per unit time; prevalence counts all existing cases in the population at a point or period.
Sensitivity of a test
Sensitivity equals true positives divided by true positives plus false negatives; it is the proportion of truly diseased persons correctly identified.
Cerebral malaria
Severe falciparum malaria with coma or altered consciousness, convulsions or coma not explained by another cause; treated with parenteral artesunate.
Hypnozoite
Dormant liver-stage form of Plasmodium vivax and ovale that can reactivate months later, causing relapse; cleared by primaquine after G6PD testing.
Indoor residual spraying
Application of a residual insecticide to interior wall surfaces of dwellings to kill malaria vectors resting indoors after feeding; a core vector-control intervention.
Aedes aegypti breeding habit
A day-biting mosquito that breeds in clean stagnant water in domestic containers; source reduction by emptying and covering containers is the main control.
Mass drug administration
Annual single-dose administration of DEC plus albendazole to entire at-risk populations for five years to interrupt lymphatic filariasis transmission.
Bio-toilet in coaches
Coach toilet using anaerobic bacteria in a bio-digester tank to decompose human waste, avoiding discharge of untreated excreta on railway tracks.
Residual chlorine test
On-site test of free chlorine remaining after disinfection; a residual of about 0.2 to 0.5 mg per litre indicates effective chlorination of water.
Rule of nines
Burn extent estimate: each arm 9%, each leg 18%, front trunk 18%, back trunk 18%, head 9%, perineum 1% of total body surface area.
Heat stroke
Medical emergency with core temperature above 40 degrees Celsius and altered mental status; requires rapid cooling and urgent hospital transfer.
KAP survey
Assessment of knowledge, attitude and practice in a community; it identifies the gap between what people know and what they actually do.
Interpersonal communication
Face-to-face health education between a worker and community members; most effective for behaviour change because it allows dialogue, questions and local tailoring.
ASHA

VHSNC
Village Health, Sanitation and Nutrition Committee, a panchayat-linked body that plans local health action and manages untied funds for village-level activities.
National Vector Borne Disease Control Programme
Programme covering malaria, dengue, chikungunya, Japanese encephalitis, kala-azar and lymphatic filariasis through integrated vector control and case management.
Herd immunity threshold
The proportion of a population that must be immune to stop sustained transmission, calculated as 1 minus 1 divided by the basic reproduction number.
Rapid diagnostic test for malaria
Immunochromatographic strip detecting parasite antigens such as HRP-2 or pLDH in a finger-prick blood sample; gives a result in about 15 minutes.
National Air Quality Index
Six-category index from Good to Severe covering pollutants such as PM2.5, PM10, NO2, SO2, CO, ozone, ammonia and lead, reported as the worst sub-index.
Vitamin B1 deficiency
Lack of thiamine causes beriberi, with peripheral neuropathy in the dry form and heart failure with oedema in the wet form.
Adult CPR ratio
For adults, deliver 30 chest compressions followed by 2 rescue breaths, compressing at 100 to 120 per minute to a depth of 5 to 6 centimetres.
Rogi Kalyan Samiti
Hospital-level patient welfare committee that manages user charges and local facility improvements to strengthen accountability and service quality.
