GS Paper 1
Vallabhacharya
News: The 545th birth anniversary of Mahaprabhu Vallabhacharya has been recently celebrated.
Early Life:
- Vallabhacharya was born into a Brahmin family in Champaran, which is now located in the Raipur district of Chhattisgarh.
- His birth anniversary is observed in India on Krishna Paksha Ekadashi of the Vaishakha month of the Hindu calendar as Vallabhacharya Jayanti.
Role in the Bhakti Movement:
- He emerged as one of the pioneers of the Bhakti movement.
- He was a contemporary of Sri Chaitanya Mahaprabhu, contributing significantly to the revival of devotional practices in Hinduism.
Founding Pushtimarg Sect:
- Vallabhacharya established the Krishna-centered Pushtimarg sect, which translates to “the path towards grace,” within the Vaishnavism tradition.
- He propagated the philosophy of Shuddhadvaita.
Philosophical Tenets:
- Pushtimarga Emphasis: Within Pushtimarg, Vallabhacharya emphasized Bhakti, or devotional love and surrender, as the primary means for devotees to attain salvation, focusing on devotion to Lord Krishna.
- Shuddhadvaita Philosophy: Vallabhacharya’s philosophy of Shuddhadvaita posits pure non-dualis.
- It asserts that the individual soul (atman) is not distinct from the supreme reality (Brahman) but is rather a part of it.
- Unlike Advaita philosophy by Shankaracharya, it rejects the concept of maya (illusion).
Literary Contributions: Vallabhacharya’s significant literary works include
- Anubhashya on Brahma Sutra,
- Subhodhini Vyakhya of Bhagavat,
- Siddhanta-Rahsya,
- Bhagavat Leela Rahasya,
- Ekanta-Rahsya,
Catatumbo Lightning
News: Catatumbo lightning emerges from the convergence of multiple factors, creating the distinct conditions necessary for its occurrence.
Definition: “Catatumbo lightning” is a natural phenomenon specific to the Catatumbo River area at Lake Maracaibo in Venzuela.
- It is named after the Catatumbo River that feeds into the lake.
Location: It occurs over the mouth of the Catatumbo River where it empties into Lake Maracaibo in Venezuela. This area is called as “the lightning capital of the world”.
- Lake Maracaibo in Venezuela is the largest lake in Latin America.
- It is also among the oldest water bodies on the planet.
- Its proximity to the Andes Mountains and the Caribbean Sea creates a unique geographical setup that plays a crucial role in the frequency of lightning in the region.
Frequency and Duration: Catatumbo lightning is renowned for its remarkable frequency and duration, with occurrences spanning up to 160 nights annually.
Mechanism of Lightning:
- Catatumbo lightning materializes when warm, moisture-laden air originating from the Caribbean Sea converges with cooler air descending from the Andes mountains.
- This collision of air masses generates towering cumulonimbus clouds, setting the stage for the electrifying display.
- Within these big clouds, vigorous winds and temperature differentials provoke the accumulation of electrical charges.
- When the electrical potential reaches a critical threshold, the stored energy discharges in the form of awe-inspiring lightning bolts.

India VIX (Volatility Index)
News: India VIX has surged to a 15-month
Volatility Index:
- The Volatility Index measures the market’s anticipation of volatility in the near term.
- During moments of market volatility, the market typically moves sharply up or down, and the VIX tends to climb.
- VIX falls as volatility falls.
- VIX is not the same as a price index like the NIFTY.
- The price index is calculated by taking the price movement of the underlying equities into account.
- The Volatility Index is calculated as an annualized percentage using the order book of the underlying index options.
India VIX:
- India VIX reflects investors’ perceptions of market volatility in the near term, i.e. it portrays market volatility over the next 30 calendar days.
- The higher the India VIX number, the greater the predicted volatility, and vice versa.
- The India VIX is calculated by the NSE from the order book of NIFTY options.
- India VIX mirrors the state of risk among investors.
- When the India VIX is high, the market expects considerable shifts, indicating a volatile time.
- However, if the India VIX is low, it signifies that the market is anticipating minute changes.

Widal Test
News: In India, healthcare providers widely employ the Widal test to diagnose typhoid fever, utilized across both public and private healthcare sectors.
Definition: The Widal blood test is used to diagnose typhoid fever (enteric fever).
- As with other infections, our immune system produces antibodies in the blood against the bacteria, causing enteric fever.
- The Widal test rapidly detects and quantifies these antibodies.
- It’s a point-of-care test and doesn’t need special skills or infrastructure.
Typhoid
⮚ Typhoid fever is a bacterial infection that is caused by is caused by Salmonella typhiand other related bacteria. ⮚ Typhoid spreads through contaminated food and water. ⮚ Its symptoms are high fever, stomach pain, weakness, nausea, vomiting, diarrhoea or constipation, and a rash. ⮚ Some people, called carriers, may remain symptom-free and shed the bacteria in their stool for several months to years. ⮚ The subsequent treatment usually consists of tablets, typically in urban areas, or injections in rural ones. ⮚ As per the World Health Organisation, 90 lakh people are diagnosed worldwide with typhoid every year and 1.1 lakh die of it. |
Why is the Widal Test Inappropriate for Testing Typhoid in India?
- Single Test Insufficiency:
- A single positive Widal test result doesn’t definitively diagnose typhoid, while a negative result doesn’t rule it out.
- Confirming an active infection requires testing at least two serum samples taken 7-14 days apart, but this is often impractical.
- Baseline Antibody Levels:
- In regions with high and sustained typhoid prevalence, baseline levels of antibodies against the bacteria may already be present in the blood.
- Without knowing these baseline levels, accurately interpreting the test is challenging, especially considering different cut-off values specified by various test kit manufacturers.
- Cross-Reactivity and False Results:
- Reagents used in the Widal test can cross-react with antibodies from infections caused by other pathogens or in individuals vaccinated against typhoid, potentially leading to false positives.
- Additionally, prior antibiotic therapy can influence antibody levels, resulting in false negatives.
- Erroneous Test Results Impacting Burden Assessment:
- The Widal test’s tendency to produce inaccurate results obscures the true burden of typhoid fever in India, hampering effective disease management and prevention efforts.
- Issues Contributing to Test Inaccuracy:
- A lack of awareness of the proper time at which to collect a blood sample, along with a lack of standardisation of kits and poor quality-control compound the problem.
- High Cost of Testing and Treatment:
- Each Widal test typically costs several hundred rupees, placing a financial strain on patients, particularly in resource-constrained settings.
- Antimicrobial Resistance (AMR) Concerns:
- The irrational use of antibiotics is a major cause of antimicrobial resistance (AMR).
- Some strains of Salmonella are also resistant to multiple drugs.
- Continued irrational use of the Widal test, which facilitates unnecessary use of antibiotics, will make it more difficult to control this preventable disease.
Way Forward:
- Efforts should be directed towards developing superior point-of-care tests to replace the Widal test, enhancing accuracy and reliability in diagnosing typhoid fever.
- Prioritizing measures to guarantee adequate and safe food and water supplies, along with functional sanitation systems.
- Adopting a ‘hub and spoke’ model in healthcare delivery can optimize resources, with peripheral sites collecting samples and district hospitals and medical colleges serving as hubs for sample processing.
-
- These facilities can also double as research centers to generate regional prevalence and susceptibility data.
-
- The Indian Council for Medical Research should continue to publish annual reports highlighting typhoid bacteria’s resistance patterns, aiding in informed decision-making for treatment protocols.
- Efforts should be made to increase sample testing coverage and reporting to provide comprehensive susceptibility data across different regions.
- Given the presence of symptom-free carriers, continuous environmental surveillance and data-sharing are imperative to effectively monitor and mitigate the spread of typhoid fever.
