Meningococcal Disease Surveillance Intensified in Meghalaya

Meningococcal Disease

Causative Agent: Neisseria meningitidis, a bacterium.
Nature of Disease: Causes acute bacterial meningitis and may also lead to septicemia, which can become life-threatening rapidly.

Spread

• Transmitted through respiratory droplets released during coughing or sneezing.
• Requires close contact for transmission.
• Spreads faster in crowded settings such as hostels, military barracks and dormitories.

Risk Factors

• Overcrowding increases transmission probability.
• Low immunity makes individuals more vulnerable.
• Unvaccinated populations are at higher risk.
• Seasonal peaks may be observed in outbreaks.

Symptoms

• High fever accompanied by severe headache.
• Neck stiffness, indicating meningeal irritation.
• Vomiting and altered sensorium.
• Purplish rash in septicemic cases.
• Can rapidly progress to shock if untreated.

Treatment

• Early administration of antibiotics is critical for survival.
• Chemoprophylaxis is advised for close contacts to prevent secondary spread.

Vaccination

MenACWY vaccine available.
MenB vaccine available.

Important Bacterial Diseases (For Comparison)

Tuberculosis | Typhoid | Cholera | Plague | Diphtheria

Important Viral Diseases

COVID-19 | Measles | Influenza | Dengue | Hepatitis B | Rabies

Key Insight: In densely populated settings, meningococcal disease can spread quickly. Early diagnosis, antibiotic therapy and vaccination significantly reduce mortality rates.

International Law and UN Charter Article 2(4) Amid Global Conflicts

Context

In the backdrop of the Russia–Ukraine war, the Gaza conflict, U.S. actions in Venezuela and rising great-power rivalry, scholars argue that international law is weakening. The editorial counters this claim by emphasising its continued resilience.

UN Charter – Article 2(4)

• Prohibits the threat or use of force against the territorial integrity or political independence of states.
• Forms the foundation of the post-World War II international order.

Exceptions

Article 51 permits self-defence if an armed attack occurs.
• The UN Security Council may authorise use of force.

Even when states violate these norms, they typically justify actions within the legal framework, indicating that international law continues to shape behaviour.

Summary of Argument

  1. Repeated Violations Yet Survival
    • Conflicts such as the Falklands War (1982), Gulf War (1990–91), Iraq War (2003), Libya and Syria strained Article 2(4).
    • Despite breaches, the broader legal system endured.
  2. Legal Justification by Powerful States
    • In the 1990s–2000s, the U.S. expanded interpretations of self-defence to justify interventions.
    • This demonstrates that even powerful states seek legal legitimacy.
  3. Current Concern
    • A growing disregard for legal justification in populist-authoritarian politics may undermine norms more seriously than isolated violations.
  4. International Law Beyond War
    International law also governs:
    • Trade
    • Aviation
    • Climate agreements
    • Human rights
    • Maritime law
    • Outer space
    • Biological and chemical weapons

Examples cited:
High Seas Treaty
• Pandemic Agreement
International Criminal Court
• Regional human rights courts

These institutions continue functioning despite geopolitical instability.

New GDP Series with 2022–23 Base Year: FY26 Growth at 7.6%

Context

The government released revised national accounts with base year 2022–23. Second advance estimates peg FY2025–26 GDP growth at 7.6%, higher than the earlier 7.4%.

GDP (Gross Domestic Product)

• Represents the total value of final goods and services produced within India in a year.
• Formula: GDP = GVA + Taxes on products − Subsidies.
• Used to measure the overall size of the economy.

GVA (Gross Value Added)

• Measures value addition by producers across sectors such as agriculture, industry and services.
• Formula: GVA = Output − Intermediate Consumption.
• Reflects sector-wise performance more directly.

Why GVA Is Analytically Preferred

• Directly shows sectoral contribution.
• Minimises distortions from tax changes.
• Useful for analysing structural shifts.
• GDP can fluctuate due to indirect tax variations rather than real production changes.

Key Changes in the New Series

• Base year shifted from 2011–12 to 2022–23.
• Improved methodology adopted.
• Greater use of GST data and enhanced datasets.
• Historical growth numbers revised.

Important Data

• FY26 GDP growth: 7.6% (Second Advance Estimate).
• Earlier estimate: 7.4%.
• FY25 revised upward to 7.1% (earlier 6.5%).
• FY24 revised downward to 7.2% (earlier 9.2% in old series).
