Mpox Diagnostic Test

  • 06 Oct 2024

In News:

In an important move to improve global access to Mpox testing, the World Health Organization (WHO) has listed the first Mpox in vitro diagnostic under its Emergency Use Listing procedure.

  • Context of Mpox Outbreak:
  • Since January 2022, mpox has spread to 121 countries.
  • By September 2024, there were 103,048 confirmed cases and 229 deaths.
  • Diagnostic Test Approval:
  • WHO approved Abbott Laboratories’ PCR diagnostic test, Alinity MPXV assay, for emergency use.
  • This test detects mpox virus DNA from skin swabs, intended for trained lab personnel.
  • Emergency Use Listing (EUL) Procedure:
  • Allows WHO to expedite approval of unlicensed vaccines, treatments, and diagnostic tests during public health emergencies.
  • In August, WHO called for manufacturers to submit diagnostic tools to aid low-income countries.
  • Current Testing Landscape:
  • Limited testing capacity has hindered response, especially in Africa, where over 30,000 suspected cases were reported in 2024.
  • 35 laboratories in India are now equipped to test suspected mpox cases.
  • Importance of Early Diagnosis:
  • Early detection facilitates timely treatment and control of the virus, essential in outbreak areas.
  • Characteristics of the Alinity MPXV Assay:
  • Utilizes real-time PCR to detect mpox virus (clade I/II) DNA from lesion materials.
  • Designed for skilled laboratory personnel familiar with PCR techniques.
  • Ongoing Efforts:
  • WHO is reviewing three additional mpox diagnostic tests and negotiating with more companies to enhance availability.
  • Efforts include addressing the spread of a new variant, clade Ib, which is affecting more women and children.
  • Public Health Implications:
  • Expanding access to diagnostics is vital for managing the mpox outbreak and protecting populations, particularly in underserved regions.
  • WHO emphasizes the importance of quality-assured medical products in containing the virus spread.

Discovery of New Hammerhead Shark Species

  • 06 Oct 2024

In News:

A team of marine biologists led by a Florida International University researcher has described a new species of the shark genus Sphyrna from the Caribbean and the Southwest Atlantic.

  • New Species: Named Sphyrna alleni (common name: shovelbill shark).
  • Habitat: Found in coastal waters, estuaries, coral reefs, and seagrass beds from Belize to Brazil, with confirmed presence in:
    • Caribbean: Belize, Panama, Colombia, Trinidad and Tobago.
    • Southwestern Atlantic: Brazil.
  • Characteristics:
    • Small species, less than 1.5 m in length.
    • Distinctive flat, shovel-shaped head lacking indentations on the anterior edge.
    • Different from Sphyrna tiburo:
      • More rounded anterior margin.
      • Absence of lobules on the posterior margin.
      • Higher precaudal vertebral count (80-83 vs. ~73 in Sphyrna tiburo).
  • Evolutionary Insight: Possible sister lineage to Sphyrna vespertina, suggesting Sphyrna tiburo diverged later.
  • Conservation Status:
    • Hammerhead sharks are highly threatened, primarily due to overfishing.
    • Most species, except Sphyrna gilberti, are listed as Vulnerable, Endangered, or Critically Endangered by the IUCN.
    • Current IUCN assessment of Sphyrna tiburo as Globally Endangered may need reevaluation considering the new findings.
  • Management Recommendations:
    • Increased management efforts needed for Sphyrna alleni, particularly restrictions on gillnets and trawls, which significantly impact this species.
  • Publication: Findings reported in the journal Zootaxa.

Shanghai Cooperation Organisation (SCO)

  • 06 Oct 2024

In News:

  • External Affairs Minister S. Jaishankar will attend the Shanghai Cooperation Organisation (SCO) Heads of Government meeting in Islamabad on October 15-16, 2023.
  • This marks the first visit by an Indian External Affairs Minister to Pakistan since Sushma Swaraj in 2015.

Context of the Visit:

  • The visit is primarily for the SCO meeting, reflecting India's focus on regional cooperation mechanisms.
  • No bilateral meetings have been scheduled as of now, although Jaishankar's presence is based on "reciprocity" following Pakistan's participation in an earlier SCO meeting in India.

SCO Overview:

  • Established on June 15, 2001, in Shanghai; evolved from the "Shanghai Five" formed in 1996.
  • Original members included China, Russia, Kazakhstan, Kyrgyzstan, Tajikistan, and later Uzbekistan.
  • Current members: India, Pakistan, Iran, and others, with Afghanistan and Mongolia holding Observer Status.

Significance of the SCO:

  • Focuses on security cooperation, primarily among Asian nations.
  • Seen as an alternative to Western international frameworks, especially with heavyweights like Russia and China positioning against US influence.
  • India's inclusion alongside Pakistan in 2017 reflects the geopolitical jostling between Russia and China.

Geopolitical Dynamics:

  • While SCO promotes cooperation, underlying tensions remain, particularly between India and Pakistan, and India and China.
  • The organization has limited tangible outcomes due to member states' rivalries and differing interests.

India's Objectives in SCO:

  • Provides a platform for enhancing relations with Central Asian countries, addressing common security concerns.
  • Involves participation in the Regional Anti-Terrorist Structure (RATS) to combat terrorism and drug trafficking.

India-Pakistan Relations:

  • Jaishankar's visit is seen in light of ongoing tensions; India shares difficult relations with both China and Pakistan.
  • India canceled a summit under its presidency last year, opting for a virtual format instead.

Implications for Regional Politics:

  • The visit comes shortly after the Jammu and Kashmir Assembly elections, with potential implications for India-Pakistan ties.
  • Despite attending the SCO meeting, there is little expectation of progress in the India-Pakistan peace process.
  • Recent statements from the Indian government criticize Pakistan for hosting wanted individuals, reflecting ongoing diplomatic tensions.

Strategic Importance:

  • Participation in SCO allows India to engage with key regional players, including Russia, China, and Central Asian leaders.
  • The meeting serves as preparation for India's participation in upcoming BRICS discussions, emphasizing the interconnectedness of these groupings.
