Cholera Disease Profile & Pathogenesis

ЁЯФ╣ Why in News & Recent Development

Global public health monitoring bodies emphasized that cholera remains a major waterborne disease causing thousands of annual fatalities in regions lacking access to clean drinking water and modern sanitation facilities.

ЁЯФ╣ Pathogen Profile and Modes of Transmission

Cholera is an acute diarrheal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. The bacteria thrive in warm, brackish, or coastal waters and can contaminate undercooked shellfish. Transmission typically occurs through fecal-contaminated water supplies; direct person-to-person spread via casual contact is extremely rare.

ЁЯФ╣ Clinical Manifestations and Medical Treatment

The incubation period ranges from 12 hours to 5 days. While many cases remain asymptomatic or mild, severe infections cause acute watery diarrhea and dehydration, which can prove fatal within hours if untreated. Management relies on rapid administration of Oral Rehydration Salts (ORS) or intravenous fluids, oral antibiotics (doxycycline, azithromycin), and zinc supplementation for pediatric patients aged 6 months to 5 years. Antidiarrheal agents are not recommended.

Minimum Support Price (MSP) Reforms & Agricultural Support

ЁЯФ╣ Why in News & Recent Development

Farmer protests in Madhya Pradesh regarding the procurement of summer moong (green gram) concluded after the state government guaranteed procurement of 60% of estimated produce (up from 25%), triggering nationwide discussions on structural reforms in the Minimum Support Price (MSP) framework.

ЁЯФ╣ Institutional Mechanism and Price Calculation

MSPs are announced at the start of sowing seasons based on recommendations from the Commission for Agricultural Costs and Prices (CACP)тАФan attached office of the Ministry of Agriculture & Farmers WelfareтАФand approved by the Cabinet Committee on Economic Affairs (CCEA). The government notifies MSP for 22 mandated crops plus a Fair and Remunerative Price (FRP) for sugarcane. MSP uses the A2 + FL formula (paid-out costs plus imputed value of family labor) set at a minimum 1.5 times the cost of production. The National Commission on Farmers (M.S. Swaminathan Committee) recommended fixing MSP at 50% above the comprehensive C2 cost (inclusive of land rent and interest on capital), which has not been legally adopted.

ЁЯФ╣ Fiscal, Ecological, and Global Trade Challenges

Extending legal MSP procurement across all notified crops carries an estimated fiscal burden of тВ╣10тАУ17 lakh crore, crowding out capital expenditure in rural infrastructure. In semi-arid regions, assured procurement of water-intensive crops like paddy has accelerated groundwater depletion and monoculture. Nationally, physical procurement remains concentrated among ~6% of farmers (per the Shanta Kumar Committee, 2015). Furthermore, unlimited price-support procurement risks exceeding the 10% de minimis limit for Amber Box domestic support under the World Trade Organization (WTO) Agreement on Agriculture.
