1. Human Metapneumovirus (HMPV) Cases in China
Context:
- A sharp rise in acute respiratory diseases in China, including Human Metapneumovirus (HMPV), influenza, and respiratory syncytial virus (RSV).
- Increase noted especially in northern provinces of China.
- No red flag raised by WHO or US CDC; considered a seasonal occurrence.
Key Points:
- About HMPV:
- First identified in 2001 (Netherlands) in children.
- Affects children, elderly, and immunocompromised populations.
- Causes upper and lower respiratory tract infections; most common is mild, but can lead to severe illness requiring hospitalization.
- Reinfection common as immunity from HMPV is weak.
- Global Impact:
- Contributes to 3%-10% of hospital admissions for respiratory infections in children.
- Linked to 1% of deaths from acute lower respiratory infections in children (2021 data).
- Higher fatality risk in low- and middle-income countries and in children <6 months.
- China’s Situation:
- Rise in cases attributed to heightened surveillance and testing.
- Linked to the ongoing flu season and usual seasonal pathogens.
- Indian health experts consider it “not unusual.”
- India’s Preparedness:
- No inexpensive diagnostic tests for HMPV widely available.
- Testing primarily limited to ICMR network.
- Recent expansion in laboratories for testing due to the spike in China.
- Mortality rate: 1% in young children globally.
- Key Challenges:
- Need for a regulatory framework to enable the approval of diagnostic tests.
- Importance of routine testing for HMPV, especially in acute respiratory disease cases.
- Way Forward for India:
- Strengthen surveillance for HMPV and novel pathogens.
- Increase awareness and research on low-knowledge pathogens.
- Facilitate testing frameworks to enhance diagnostic capacity.
2. Avian Influenza and Animal Quarantine
Context:
- India reports its first case of avian influenza (H5N1) in wild animals.
- Deaths of 3 tigers and 1 leopard at a Nagpur rescue center.
- The Union Animal Husbandry Ministry issued directives to states for containment.
Key Points:
- Avian Influenza (H5N1):
- A highly contagious virus that primarily affects birds but can cross species barriers.
- Cases have been observed in cattle, goats, and wild animals (notably tigers).
- Virus transmission to humans is rare but possible.
- Incident in Maharashtra:
- Animals tested positive after death; samples analyzed by the National Institute of High-Security Animal Diseases (Bhopal).
- Likely source: food (possibly infected chicken) served to animals at the rescue center.
- First confirmed case of avian flu among animals in India.
- Government Directives:
- Quarantine measures for symptomatic animals, particularly tigers and other felines, to prevent cross-species transmission.
- Enhanced biosecurity protocols:
- Restrict personnel and veterinarian movement.
- Temporarily shut down affected facilities.
- Disinfect areas thoroughly.
- Response Mechanisms:
- National Joint Outbreak Response Team deployed to manage the situation.
- Investigation into infection sources underway.
- Ministry of Environment, Forest, and Climate Change also alerted.
- Precautionary Measures:
- Avoid handling infected animals directly.
- Restrict infected animals’ movement to healthy populations.
- Regular monitoring of livestock and wildlife for early detection.
- Global Context: Similar incidents reported in the U.S. and Vietnam, highlighting the global nature of the avian influenza threat.
3. Decoding the Indus Valley Script
Context: Tamil Nadu Chief Minister M.K. Stalin announced a $1-million prize for decoding the undeciphered script of the Indus Valley Civilization (IVC).
Key Points:
- Significance of the Script:
- Indus Valley script remains undeciphered even after 100 years since the discovery of the IVC by Sir John Marshall.
- Understanding the script is crucial for uncovering the cultural, administrative, and societal aspects of the IVC.
- Initiative by Tamil Nadu:
- Prize of $1 million announced to encourage global experts in decoding the script.
- Efforts involve archaeologists, computer experts, and linguists, emphasizing interdisciplinary research.
- Research Support:
- ₹2-crore grant to establish a chair in the name of noted archaeologist and epigraphist Iravatham Mahadevan.
- Joint research efforts by the State Department of Archaeology and the Indus Research Centre at Chennai-based Roja Muthiah Library.
- Historical Importance:
- The Indus script, found on seals and other artifacts, is one of the world’s oldest written forms but remains a mystery.
- Deciphering it could reveal details about language, trade, governance, and religion of the IVC.
