Secondary Pollutants

Context

• Recent CREA analysis shows secondary pollutants form nearly one-third of Delhi’s annual PM2.5 load.
• Their rising share explains persistent pollution despite curbs on visible local emission sources.

What are Secondary Pollutants?

• Secondary pollutants are not emitted directly from identifiable pollution sources.
• They form in the atmosphere through chemical reactions involving primary gaseous pollutants.
• Formation is influenced by sunlight, humidity, temperature, and atmospheric stagnation.
• These pollutants often accumulate downwind and over time, complicating regulatory control.

Major Secondary Pollutants

• Secondary PM2.5 includes ammonium sulfate and ammonium nitrate particles.
• Ozone (O₃) forms from nitrogen oxides and volatile organic compounds under sunlight.
• Acids such as sulfuric and nitric acid contribute to acid deposition.
• Photochemical smog components include peroxyacetyl nitrates and nitrogen dioxide.

Formation Process

• Precursor gases include SO₂, NOx, and ammonia from multiple anthropogenic sources.
• SO₂ originates from coal-based power plants and petroleum refineries.
• NOx is released mainly by vehicles and thermal power stations.
• Ammonia emissions arise from fertiliser application, livestock, and sewage systems.
• SO₂ oxidises into sulfate, later reacting with ammonia to form ammonium sulfate.
• NOx oxidises into nitric acid, combining with ammonia to produce ammonium nitrate.

Role of Weather Conditions

• High humidity, fog, low temperatures, and weak winds accelerate chemical transformations.
• Winter conditions enable rapid particle formation within hours and prolonged atmospheric persistence.

Implications

• Secondary aerosols travel hundreds of kilometres, creating regional and transboundary impacts.
• Delhi’s air quality is influenced by emissions from coal-dominated states beyond NCR.
• Winter smog intensifies due to secondary PM2.5, even when local sources are restricted.
• Policies focusing only on PM10 or local sources overlook precursor gas control.
• Fine secondary particles penetrate deep lungs, raising respiratory and cardiovascular disease risks.

Rabies

Nature and Classification

• Rabies is a vaccine-preventable, zoonotic, viral disease affecting humans and animals.
• It is caused by the Rabies virus (RABV), targeting the central nervous system.
• Rabies infects all mammals, including dogs, cats, livestock, and wildlife species.
• It is classified as a Neglected Tropical Disease (NTD).

• The disease disproportionately affects poor, marginalised, and vulnerable populations.

Transmission Pathways

• Rabies spreads through saliva of infected animals.
• Transmission usually occurs via bites and scratches.
• Direct contact with mucosa, such as eyes or mouth, can transmit infection.
• Open wounds exposed to infected saliva also facilitate viral entry.

Clinical Forms of Rabies

• Rabies manifests in two distinct clinical forms.
• Furious rabies is marked by hyperactivity, agitation, and hallucinations.
• Patients may show hydrophobia and erratic behaviour in this form.
• Paralytic rabies is characterised by muscle weakness progressing to paralysis.
• Paralytic form gradually leads to coma and eventual death.

Incubation Period

• The incubation period typically ranges between 2–3 months.
• In some cases, incubation may be as short as one week.
• In rare instances, symptoms may appear after one year.

Symptoms and Disease Progression

• Early symptoms include fever, pain, and general discomfort.
• Patients often experience tingling, pricking, or burning at the bite site.
• As the virus reaches the central nervous system, severe neurological symptoms emerge.
• Progressive inflammation of the brain and spinal cord develops.
• Once clinical symptoms appear, rabies is fatal in 100% of cases.

Prevention and Control

• Rabies prevention focuses on interrupting transmission at the animal source.
• Vaccinating dogs, including puppies, is the most cost-effective prevention strategy.
• Dog vaccination significantly reduces human rabies cases by blocking viral spread.

Candida Auris

Context

• An Indian-led study warns Candida auris is becoming more virulent and globally widespread.
• High mortality persists despite treatment, raising serious global public health concerns.

What is Candida auris?

• Candida auris is a multidrug-resistant fungal pathogen causing severe invasive infections.
• It primarily affects hospitalised and immunocompromised patients.
• First identified in 2009, it is now recognised as an emerging global health threat.
• High fatality rates and frequent treatment failures distinguish it from other Candida species.

Vector and Reservoir

• Candida auris mainly spreads within healthcare settings such as hospitals and care facilities.
• It persists on human skin, enabling prolonged colonisation without symptoms.
• The fungus survives for long periods on medical devices and inanimate surfaces.
• Environmental persistence complicates infection control and eradication efforts.

Clinical Symptoms

• Symptoms vary depending on the site of infection.
• Clinical presentation often mimics bacterial sepsis, delaying accurate diagnosis.
• Common signs include fever, chills, and low blood pressure.
• Patients may experience tachycardia and severe bloodstream infections.
• Invasive infections frequently result in candidemia, increasing fatality risks.

Key Features

• Multidrug resistance limits effectiveness of standard antifungal therapies.
• Resistance spans multiple antifungal drug classes, narrowing treatment options.
• High virulence leads to mortality rates exceeding 50%, even after therapy.
• Exhibits morphological flexibility, switching between yeast and filamentous forms.
• Rapid adaptation enables effective immune evasion and environmental stress tolerance.

Transmission Pathways

• Spreads through direct contact with infected or colonised individuals.
• Asymptomatic carriers significantly contribute to unnoticed transmission.
• Transmission occurs via contaminated surfaces and medical equipment.
• Invasive devices such as catheters and ventilators heighten infection risk.
