  • India’s Sickle Cell Challenge  

    Why in the News?

    The Prime Minister has reaffirmed the government’s dedication to addressing sickle cell disease, a genetic blood disorder that alters the shape of red blood cells.

    About the National Sickle Cell Anaemia Elimination Mission:

    • The Union Budget 2023-24 announced a mission to eliminate sickle cell anemia by 2047. The mission focuses on awareness and screening programs for people ages 0 to 40.
    • The mission aims to reduce the burden of sickle cell disease, which primarily affects India’s tribal belt (Odisha, Jharkhand, Chhattisgarh, Madhya Pradesh, Maharashtra).
    • These include nationwide screening programs and the inclusion of vital medicines like hydroxyurea in the essential medicines list, improving access to treatment.

    Challenges faced by the Indian Government:

    • High Disease Burden: India has the world’s second-largest burden of sickle cell disease, with over a million affected individuals, primarily in tribal areas.
    • Low Treatment Coverage: Only 18% of those affected receive consistent treatment, with significant drop-offs in screening, diagnosis, and treatment adherence.
    • Stigma and Misinformation: Social stigma around the disease, myths such as “God’s curse” or “black magic,” and mistrust of public health systems, particularly in tribal areas, result in delayed diagnosis and treatment.
    • Treatment Adherence Issues: Challenges include inconsistent availability of medicines like hydroxyurea, long travel distances for treatment, and stock shortages at health centers.
    • Poor Vaccination Coverage: Vaccination, which reduces infection rates and improves quality of life, remains inadequate in many affected regions.
    • Research and Development: The lack of ongoing research into treatments and understanding of the disease in India, and the unaffordability of emerging therapies like gene therapy, hinder long-term progress.
    • Financial and Operational Gaps: Health systems in tribal areas require additional funding and operational strengthening to address region-specific health challenges effectively.

    What are the WHO recommendations?

    • Early Identification: Implement newborn screening programs to identify sickle cell disease at birth.
    • Integration into Health Systems: Sickle cell management should be integrated into national health services. This includes establishing specialized centers for comprehensive care and ensuring that primary healthcare providers are trained in managing sickle cell disease.
    • Public Education and Awareness: Conduct public education campaigns to raise awareness about sickle cell disease, reduce stigma, and inform communities about genetic risks and prevention strategies.
    • Genetic Counseling: Provide genetic counselling to families, especially in communities with high prevalence, to inform them about the risks of having children with sickle cell disease and the importance of carrier screening.

    Mains PYQ:

    Q Stem cell therapy is gaining popularity in India to treat a wide variety of medical conditions including leukaemia, Thalassemia, damaged cornea and several burns. Describe briefly what stem cell therapy is and what advantages it has over other treatments. (UPSC IAS/2017)

  • The grave threat from AMR

    Why in the News?

    Ahead of the UN General Assembly High-Level Meeting on antimicrobial resistance, WHO published its first-ever guidance on Antibiotic pollution from manufacturing.

    Common Pathogens Found in India

    The three most common pathogens associated with antimicrobial resistance (AMR) in India, as reported by the Indian Council of Medical Research (ICMR), are:

    • Escherichia coli (E. coli): Known for causing gut infections, E. coli has shown a significant decrease in susceptibility to antibiotics, particularly carbapenems, from 81.4% in 2017 to 62.7% in 2023.
    • Klebsiella pneumoniae: This pathogen can lead to pneumonia and urinary tract infections. Its susceptibility to carbapenem-class antibiotics has also declined, with rates dropping from 58.5% to 35.6% and from 48% to 37.6% between 2017 and 2023.
    • Acinetobacter baumannii: Primarily associated with hospital-acquired infections, this pathogen has a high resistance rate to carbapenems, standing at 88% in 2023.

    What is Antimicrobial Resistance (AMR) and Why is it a Cause for Concern?

    • Antimicrobial resistance (AMR) occurs when pathogens evolve to survive despite the presence of antimicrobial drugs, rendering standard treatments ineffective. This situation arises mainly due to the misuse and overuse of antibiotics, leading to the development of resistant strains or “superbugs.” 
    • According to the WHO, emergence and spread of AMR could significantly undermine the effectiveness of antibiotics globally, impacting healthcare outcomes, especially for patients with multiple diseases.

    Why is AMR Increasing?

    Several factors contribute to the increasing rates of AMR in India:

    • Self-medication: Many individuals self-prescribe antibiotics for conditions like fever without proper medical consultation, often for viral infections where antibiotics are ineffective.
    • Prescribing habits: A significant percentage of antibiotics are prescribed not for treating infections but for prevention. Doctors often resort to broad-spectrum antibiotics without conducting necessary diagnostic tests, leading to inappropriate usage.
    • Lack of regulation: The management of pharmaceutical waste from antibiotic manufacturing is largely unregulated, contributing to environmental pollution and the spread of resistant bacteria.

    What needs to be done?

    • Prevention of Infections: Implementing better hygiene practices, improving sanitation, and promoting vaccinations can help reduce the incidence of infections, thereby decreasing the reliance on antibiotics.
    • Education for Healthcare Providers: Train doctors to prescribe antibiotics judiciously, reserve stronger antibiotics for hospital patients, and emphasise the importance of diagnostic testing, which can help ensure appropriate antibiotic use.
    • Regulatory Improvements: Strengthening regulations around antibiotic manufacturing and waste management is crucial for controlling antibiotic pollution and preventing the emergence of resistant strains.

    Mains PYQ:

    Q Can overuse and free availability of antibiotics without Doctor’s prescription, be contributors to the emergence of drug-resistant diseases in India? What are the available mechanisms for monitoring and control? Critically discuss the various issues involved.  (UPSC IAS/2016)

  • What is Wallace Line?

    Wallace Line

    Why in the news?

    The Wallace Line, a distinct transition zone between Asia and Australia, has long fascinated researchers due to its unique characteristics.

    What is Wallace Line?

    Details
    What is it?
    • A bio-geographical boundary separating the eco-zones of Asia and Australia.
    • It was identified by British explorer Alfred Russel Wallace in 1863 during his explorations.
    • It is an imaginary line that intersects the Lombok Strait between the Indonesian islands of Bali and Lombok to the south, and extends north through the Makassar Strait between Kalimantan (Borneo) and Sulawesi.
    Unique Features
    • Divides species with distinct evolutionary histories.
    • Asiatic species (tigers, elephants) are found to the west; Australian fauna (kangaroos, marsupials) dominate the east.
    • Despite their geographical proximity, these species evolved separately.
    Impact on Wildlife
    • Birds and mammals are particularly influenced, with few species crossing the line.
    • Flora is less affected, though species like Eucalyptus stay on the Australian side.
    Impact on Marine Species
    • While the Wallace Line is a barrier for terrestrial species, it doesn’t stop marine life. 
    • The area between the Wallace Line and the Sahul Shelf (near Australia) is known as the Coral Triangle, the most biodiverse marine environment on Earth.
    Formation
    • Result of Australia’s drift from Antarctica and subsequent collision with Asia around 35 million years ago.
    • Climate shifts led to cooler, drier Australia and tropical Asia.
    • This collision created a deep-water channel that still acts as a natural barrier for species migration.
    Pleistocene Epoch Influence
    • During the Pleistocene epoch, lower sea levels exposed land bridges.
    • Deep waters between Asia and Australia prevented species migration, maintaining the boundary.

     

    Note: 

    Weber Line more accurately defines the balance point where the influence of Asian and Australian species is nearly equal, whereas the Wallace Line marks a sharper divide.
