One of the commonest causes of illness, a sore throat often clears up on its own, but knowing what's causing it is important to treat it properly. Viral, bacterial, or caused by allergic elements - these kinds of sore throats have different characteristics that need different responses.

Sore throats have several origins, including infection and environmental factors. Some common causes include:

Viral infections: Viruses cause 90% of sore throat cases. Sore throats may result due to flu or common cold as well as those from chickenpox and measles that can all cause irritation.

Bacterial Infections: Streptococcus bacteria, the most common cause of strep throat, is the most common bacterial source. Strep throat is contagious and can lead to complications if untreated.

Allergies: Pollen, pet dander, and mold can trigger throat irritation, often accompanied by postnasal drip, sneezing, and watery eyes.

Environmental Factors: Dry air, pollution, and smoke can dry out or irritate the throat, creating a scratchy sensation.

Other Causes: GERD, vocal strain, even tumors may be responsible for chronic sore throats.

How to Distinguish Between Viral, Bacterial, and Allergic Sore Throats

Determining your cause of sore throat requires analysis of symptoms that accompany it, how long the sore throat lasts, and how bad the sore throat is.

Viral Sore Throats

The viruses that cause a sore throat are usually similar to a cold in their symptoms and tend to be milder than bacterial infections.

Symptoms of Viral Sore Throat

- Red, swollen throat without white patches

- Persistent cough

- Runny nose and nasal congestion

- Fever, usually mild

Duration: Viral infections last for 7–10 days without antibiotics.

Treatment: Home remedies, such as warm fluids, saltwater gargling, and over-the-counter pain relievers can help alleviate it.

Bacterial Sore Throats

Bacterial sore throats, mainly strep throat, are more severe and require prompt medical attention to prevent complications.

Symptoms of Bacterial Sore Throat

- Red and swollen tonsils with white patches or streaks of pus

- High fever

- Absence of a cough

- Nausea, vomiting, or stomach pain (especially in children)

- Small red spots on the roof of the mouth

Diagnosis: Rapid strep tests or throat cultures confirm the presence of bacteria.

Treatment: Antibiotics are necessary to eliminate the infection. Without treatment, complications like rheumatic fever or abscesses can develop.

Sore Throats Caused by Allergies

Throat irritation is caused by postnasal drip. Allergies create a buildup and drip of mucus down the back of the throat.

Allergic Sore Throat Symptoms

- Irritation of the throat and ears

- Runny eyes, sneezing, and nasal congestion

- These symptoms are usually relieved by antihistamines or removal from the source of the allergen

Duration: Allergic sore throats are sustained for as long as the allergens are exposed.

When to Seek Medical Care?

A sore throat should be taken to a doctor if:

- The condition lasts more than a week.

- There is shortness of breath or swallowing becomes painful.

- Swelling is too pronounced or the pain in the throat is extreme.

- High fever, rash, or joint pain occur along with the sore throat.

- A child shows signs of dehydration or refuses fluids due to throat pain.

Early diagnosis can prevent complications and speed recovery.

Effective Treatment for Sore Throats

Home Remedies for Viral and Allergy-Related Sore Throats

Viral infections and allergies often respond well to non-invasive treatments:

• Drink warm teas, broths, or water to soothe the throat.
• Gargling with warm, salty water can reduce inflammation.
• These help soothe an irritated throat and can alleviate coughing.

Let your body rest sufficiently. Humidifying dry air will help keep the throat moist, especially when winter is on its way.

Why Not All Sore Throats Require Antibiotics?

Bacterial infections require antibiotics such as penicillin or amoxicillin. Finish the treatment completely to avoid reoccurrence or resistance.

How to Keep Sore Throats at Bay When Winter Is Near

Prevention is better than cure, and simple lifestyle changes can reduce your risk:

• Wash your hands frequently to avoid infections.
• Avoid close contact with sick individuals.
• Use air purifiers to minimize exposure to irritants.
• Stay hydrated and maintain a balanced diet to boost immunity.

Understanding the cause of your sore throat—whether viral, bacterial, or allergic—is key to effective treatment and recovery. While many sore throats resolve on their own, seeking timely medical advice for persistent or severe symptoms can prevent complications. Prioritize self-care, and don’t hesitate to consult a doctor when needed. Remember, your throat’s health is a vital part of your overall well-being.

You may not smoke, exercise regularly, maintain a healthy weight and have no known medical condition. But could the air you breathe still increase your risk of stroke?

The answer is yes. Air pollution affects more than the lungs; it is associated with cardiovascular disease and stroke. PM2.5 fine particulate matter measuring 2.5 micrometres or less in diameter can penetrate deep into the lungs and trigger biological responses affecting blood vessels throughout the body.

How can polluted air affect the brain?

A stroke occurs when blood flow to part of the brain is interrupted or when a blood vessel ruptures.

PM2.5 exposure may contribute to inflammation, oxidative stress and dysfunction of the endothelium, the inner lining of blood vessels. It may also influence platelet activation and normal blood-clotting mechanisms, potentially favouring thrombosis.

Over time, prolonged exposure may contribute to atherosclerosis, the build-up of plaques inside arteries. If a plaque ruptures and a clot blocks an artery supplying the brain, an ischaemic stroke can occur. Air pollution may also affect blood pressure and cardiovascular function.

However, exposure does not inevitably cause a clot or stroke. It is one of several factors that may influence an individual's risk.

Can apparently healthy people also be affected?

Yes. Having no diagnosed hypertension, diabetes, high cholesterol or heart disease does not eliminate pollution-associated stroke risk.

A systematic review published in the British Medical Journal in 2015 found that a 10 µg/m³ increase in short-term PM2.5 exposure was associated with approximately a 1.1% relative increase in stroke admissions or mortality. This is a population-level association, not an individual's absolute risk or proof of causation in a particular patient.

Who needs particular attention?

Older adults and people with hypertension, diabetes, dyslipidaemia, coronary artery disease, atrial fibrillation or a previous stroke or transient ischaemic attack (TIA) warrant particular attention because their baseline vascular risk is high.

Five practical steps to reduce exposure

• Check the AQI: Monitor air-quality readings, particularly during periods of severe pollution.
• Modify outdoor activity: Reduce prolonged or strenuous exercise when air quality is poor; choose cleaner environments or indoor exercise.
• Use appropriate protection: A well-fitting N95 mask can reduce inhalation of fine particles when outdoor exposure is unavoidable.
• Improve indoor air: Consider appropriately sized HEPA filtration and minimise tobacco smoke and other combustion-related pollution.
• Manage vascular risk: Monitor blood pressure, glucose and cholesterol when appropriate, and follow prescribed treatment.

Do not start aspirin or anticoagulants solely because pollution levels are high. These medicines carry risks and should be used only when clinically indicated under medical supervision.

Individual precautions help, but sustained improvements require cleaner transport, effective industrial emission controls and prevention of waste burning.

Stroke prevention must address established medical risk factors as well as avoidable environmental exposures. The air may look clear, but that does not guarantee it is clean. Protecting the air, we breathe is also an investment in the health of our brains.

Patient developed severe malaria affecting his platelets, liver, kidneys and lungs, with the lung injury progressing to Acute Respiratory Distress Syndrome (ARDS) and requiring ventilator support.

A 45-year-old motorman developed life-threatening complications after malaria progressed to multi-organ failure, affecting his lungs, liver and kidneys and causing a significant drop in platelet count and blood pressure.

His lung function deteriorated severely, leading to Acute Respiratory Distress Syndrome (ARDS), a serious condition in which the lungs are unable to provide enough oxygen to the body. He required ventilator support with high levels of oxygen and pressure to help him breathe.

Malaria Progresses To Multi-Organ Failure

The patient was admitted in a severely ill condition after being diagnosed with malaria. By the time he reached the hospital, the infection had affected multiple organ systems.

His platelet count was low, while his liver and kidneys were affected. The most critical complication was severe lung involvement. The patient developed ARDS, resulting in significant difficulty in maintaining adequate oxygen levels and requiring mechanical ventilation. His blood pressure had also dropped significantly, necessitating medicines to support his circulation.

Severe Lung Injury Requires Ventilator Support

Malaria can sometimes become severe and affect multiple organs. In this patient, the lungs were particularly badly affected and he developed Acute Respiratory Distress Syndrome, or ARDS.

In ARDS, the lungs become severely inflamed and are unable to transfer sufficient oxygen into the bloodstream. He therefore required ventilator support, including higher oxygen and controlled pressure to help maintain adequate oxygenation. At the same time, we had to support his blood pressure and closely monitor his liver and kidney function.

Intensive Treatment Helps Patient Recover Without Dialysis

The patient was treated with appropriate anti-malarial therapy along with intensive supportive care. He was placed on ventilator support because of severe respiratory failure and was given medicines to maintain his blood pressure. His fluid status was carefully managed, while his urine output and kidney function were closely monitored.

Despite the initial kidney involvement, his urine output gradually improved and he did not require dialysis. Over the next several days, his lung function also began to improve. As his oxygenation and overall condition stabilised, the medical team was able to gradually reduce the level of ventilator support and eventually take him off the ventilator.

After approximately 7–8 days of intensive treatment and monitoring, the patient showed significant clinical improvement. He was successfully weaned off ventilator support, regained his strength and was able to walk before being discharged from the hospital.

The patient came in a very critical condition, with the lungs, liver and kidneys affected and blood pressure requiring support. The first few days were particularly important because we had to support several organ systems simultaneously while treating the malaria. His urine output improved without the need for dialysis, and his respiratory status gradually recovered. Within about a week, he was off the ventilator and eventually walked home.

When Can Malaria Become Life-Threatening?

The case highlights that malaria can, in some patients, progress beyond fever and routine symptoms and cause severe complications involving multiple organs. Lung involvement can be particularly serious, and conditions such as ARDS may require prolonged respiratory support in an intensive care setting.

Doctors advise people with malaria to seek timely medical attention, particularly if fever is accompanied by breathing difficulty, reduced urine output, unusual drowsiness, persistent vomiting, bleeding, severe weakness or low blood pressure. Early recognition of complications and appropriate supportive care can be critical in preventing further deterioration.

Diwali is a time of celebration, but the increase in air pollution caused by firecrackers can pose serious health risks, particularly for children and senior citizens. Exposure to smoke, harmful gases and fine particulate matter can irritate the respiratory system, worsen existing health conditions and put additional strain on the heart. Families must recognise early warning signs and take timely precautions to ensure everyone celebrates safely.

Who Is Vulnerable During Severe Pollution Days?

Children are particularly vulnerable because their lungs are still developing and they breathe faster than adults. Exposure to polluted air can cause coughing, sneezing, throat irritation, red or watery eyes and wheezing. Parents should watch for signs such as persistent coughing, difficulty breathing, unusual tiredness during physical activity or an increase in asthma symptoms. Even children who do not directly burst crackers can experience these effects through second-hand exposure to firecracker smoke.

Senior citizens, especially those living with asthma, chronic obstructive pulmonary disease (COPD), diabetes or heart disease, also face increased risks. Warning signs include worsening breathlessness, persistent cough, chest discomfort, unusual fatigue, dizziness and disturbed sleep. Pollution exposure can aggravate existing respiratory conditions and increase cardiovascular stress. Sudden chest pain, severe breathlessness, fainting or confusion should never be ignored and require immediate medical attention.

How To Stay Safe?

A few simple precautions can significantly reduce exposure. Families should keep children and elderly members away from areas where firecrackers are being burst, particularly during peak evening hours. Keeping windows and doors closed when outdoor pollution levels are high can help limit smoke entering the house. Avoid burning incense sticks, dhoop and other materials indoors, as these can further deteriorate indoor air quality.

If stepping outdoors is unavoidable, adults can use a well-fitted N95 mask to reduce exposure to fine particulate matter. Children should be supervised and protected from smoky environments. Individuals with asthma or COPD must continue their prescribed medication and keep their inhalers readily accessible. Families should also avoid outdoor walks and strenuous activities the morning after Diwali if pollution levels remain high.

Beyond air pollution, families must remain alert to firecracker-related injuries. In case of burns, hold the affected area under cool running water for 20 minutes and cover it loosely with a clean cloth. Avoid applying ice, toothpaste or butter. Eye injuries and accidental ingestion of harmful substances require immediate medical evaluation.

Recognising early symptoms, limiting smoke exposure and seeking timely medical care can prevent avoidable complications. This Diwali, prioritise health and safety alongside celebrations. After all, a healthy family is the greatest reason to celebrate.
