First Local Transmission of Mpox Clade I Strain in the U.S.

Context: The United States has reported the first suspected local transmission of the Clade I Mpox strain, with no international travel link identified. The confirmation raises public health concerns, as Clade I is considered more virulent than the Clade II strain that caused the global 2022 outbreak.
This incident marks a potential shift in the epidemiology of Mpox, signaling community-level spread within North America.

About Mpox

Causative Agent: Mpox (formerly known as Monkeypox) is a zoonotic viral infection caused by the Monkeypox virus (MPXV), belonging to the Orthopoxvirus genus, closely related to smallpox.
Transmission: Occurs via contact with infectious lesions, body fluids, contaminated materials, or respiratory droplets from infected individuals or animals.
Symptoms: Fever, headache, swollen lymph nodes, muscle pain, and characteristic painful skin lesions (often on face, hands, and genital areas).
Severity: Children, pregnant women, and immunocompromised individuals are more prone to complications such as secondary infections and pneumonia.

Clades of Mpox

Clade I:
- Geographic Origin: Central Africa (mainly Congo Basin).
- Fatality Rate: 1–10%.
- Severity: More virulent and transmissible.
Clade II (A & B):
- Origin: West Africa.
- Fatality Rate: <1–4%.
- Responsible for 2022 Global Outbreak.

Treatment and Prevention

Treatment: No specific antiviral cure exists. However, Tecovirimat (TPOXX) and Brincidofovir are used under emergency authorisations to manage severe infections.
Vaccination:
- Jynneos (Imvamune/Imvanex) by Bavarian Nordic is the approved vaccine offering cross-protection against both Mpox clades.
- Target groups include healthcare workers, laboratory staff, and close contacts of confirmed cases.
Public Health Response: Enhanced surveillance, contact tracing, and isolation remain critical for containment.

India’s Status

Between December 2024 and March 2025, India recorded 10 confirmed cases of Clade 1b Mpox, all traced to travel from Gulf countries.

There has been no community transmission reported domestically so far. India continues to follow WHO-recommended surveillance and vaccination guidelines under the National Centre for Disease Control (NCDC).

Ozone Pollution in Indian Cities

Context: The National Green Tribunal (NGT) has taken suo motu cognisance of a report highlighting the alarming rise of ground-level ozone pollution across major Indian cities. The tribunal noted that elevated ozone levels are closely linked to vehicular, industrial, and power-sector emissions of nitrogen oxides (NOx) and directed the Central Pollution Control Board (CPCB) to conduct an expert study and frame control measures.

Understanding Ozone Pollution

Ozone (O₃) is a gas formed when nitrogen oxides (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight. It is a secondary pollutant, meaning it is not directly emitted but produced through chemical reactions in the atmosphere.

Stratospheric ozone (“good” ozone): Forms the ozone layer that protects Earth from harmful ultraviolet (UV) radiation.
Tropospheric ozone (“bad” ozone): Accumulates near the ground, acting as a major air pollutant harmful to human health, vegetation, and ecosystems.

Scale of the Problem

Ozone Exceedance: Highest levels recorded in Delhi-NCR and Mumbai, frequently breaching CPCB safe limits (2025).
Rising Trend: Urban ground-level ozone has increased by over 30% since 2018, driven by vehicular exhaust, power generation, and industrial activity (MoEFCC, 2024).
Health Impact: Linked to ~70,000 premature deaths annually in India (WHO, 2024) due to respiratory and cardiovascular diseases.
Emission Sources:
- Transport sector: ~40% of NOx emissions.
- Power generation: ~30% of NOx emissions.
Environmental Impact: Reduces crop yields by 5–20%, damages forests, and contributes to climate warming by trapping heat.

Regulatory and Policy Response

NGT Directive (2025): Seeks a CPCB-led expert study on ozone sources and regional control strategies.
National Clean Air Programme (NCAP): Focuses on reducing particulate matter (PM₂.₅ and PM₁₀), but experts now call for integrating ozone metrics into air quality management.
CPCB Initiatives: Expanding ozone monitoring networks and promoting real-time data sharing.
Urban Interventions: Transition to cleaner fuels, e-mobility, renewable power, and stricter NOx emission norms for industries.

Way Forward

Develop Ozone Action Plans under NCAP focusing on precursor emission control.
Promote electric mobility, public transport, and low-NOx technologies in thermal plants.
Enhance green cover and urban ventilation corridors to disperse pollutants.
Strengthen public awareness on ozone exposure risks and adaptive health measures.

Nightshades Solanaceae

Characteristic Features:
- Star-shaped flowers with five petals.
- Alternate leaves.
- Often contain alkaloids that can affect the nervous system.

Toxicity and Alkaloids

Alkaloids: Nitrogen-containing compounds responsible for the bitterness and potential toxicity of many nightshades.
Solanine: A glycoalkaloid naturally present in potatoes and tomatoes.
- Low levels (in ripe potatoes and tomatoes) are safe for consumption.
- High levels (in green potatoes or sprouted tubers) can cause nausea or neurological symptoms.
These alkaloids act as natural pesticides for the plant, deterring insects and animals.

Agricultural and Medicinal Relevance

Global Crop Importance: Potatoes, tomatoes, and chillies are among the most widely cultivated vegetables in the world, contributing significantly to food security and trade.
Medicinal Uses: Alkaloids from nightshades are used in controlled doses in pharmaceuticals — for example, atropine from belladonna is used in eye treatments.
Ecological Role: Nightshades provide nectar and habitat for pollinators, playing a role in maintaining ecosystem balance.

India’s Context

India is a major producer of brinjal, chilli, and potato.
Traditional medicine has used nightshade species for centuries, though caution is advised due to their toxic properties.
The Food Safety and Standards Authority of India (FSSAI) advises avoiding consumption of green or sprouted potatoes to reduce the risk of solanine exposure.

Conclusion: Nightshades are both friend and foe — crucial for food systems yet potentially harmful if mishandled. Understanding their biology and safe usage is essential for public health and sustainable agriculture.
