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.
