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.

Leptospirosis gained attention after its cases surged in Kerala recently. The infection has also been reported in Maharashtra, Gujarat, Tamil Nadu, and Karnataka. The bacterial infection typically spreads via contact with water or soil that has been contaminated by the urine of animals infected with leptospirosis, especially during floods.

As monsoons are right at our doors, know why it is important to detect and nab dangerous infections like leptospirosis early.

What Is Leptospirosis?

Leptospirosis is a potentially serious bacterial infection sometimes called the "rat fever" because it can cause symptoms similar to the typical symptoms of common viral infections, which may not be noticeable in the early stages. It is caused by the bacteria of the genus Leptospira that are excreted in the urine of infected animals, including rats, cattle, dogs, and pigs.

In the monsoon season, there is a risk of waterlogging and contaminated animal urine mixing with floodwater and soil. Infestation occurs through direct contact with contaminated water or mud on cuts or abrasions or on the mucous membranes of the mouth, nose, and eyes. Those involved in outdoor work, sanitation, farming, construction, or who are walking in flooded streets are especially at risk.

Combating Leptospirosis In Monsoon

Health and Me spoke to Dr. Sundar Krishnan, Senior Consultant - Internal Medicine, KIMS Hospital, Thane, about how to tackle leptospirosis this monsoon.

Dr. Krishnan says, “In the early stages, it may have flu-like symptoms, and that makes early recognition challenging. Symptoms are sudden onset of high fever, chills, very severe headache, muscle pain especially in the calves and lower back, fatigue, nausea, vomiting, and red eyes.”

The expert also said that occasionally, the patient may also have abdominal pain or diarrhea. He also says it can escalate quickly to jaundice, kidney failure, difficulty breathing, meningitis, internal bleeding, or multi-organ failure and can require immediate medical care.

Dr. Krishnan recommends several prevention tips to tackle leptospirosis in monsoon:

• Avoiding contact with contaminated water by staying out of flooded areas whenever possible.

• Wearing waterproof boots and gloves for extra protection.

• Covering cuts or wounds with waterproof dressings before entering flood water.

• Maintaining good personal hygiene, washing hands and feet extensively after contact with flooded and stagnant water.

• Getting out of wet clothes as soon as possible.

• Taking measures for proper waste disposal to control rat infestation.

• Raising awareness and educating the public about the risk of leptospirosis during the rainy season.

If leptospirosis is diagnosed early and treated with antibiotics, recovery is much quicker, avoiding life-threatening complications. But if detection and treatment are delayed, the kidneys, liver, lungs, and even the brain may be affected.

The expert advises that people who are ill after being exposed to flood water and are facing fever or flu-like symptoms for more than two days should also seek medical help as soon as possible, informing their doctor about their flood water exposure.

Even though the risk of leptospirosis is high during the monsoon, the best way to steer clear of this infection is to educate the masses about its symptoms and prevention. Early clinical intervention can help de-escalate the situation promptly.

Headaches are one of the most common health complaints and are often caused by stress, lack of sleep, dehydration, excessive screen time, skipped meals, or other lifestyle factors. While most headaches are benign, experts said that frequent or unusual headaches should not be ignored, as they may signal an underlying medical condition that requires evaluation.

The experts told HealthandMe that paying attention to changes in headache frequency, pattern, and associated symptoms can help identify when medical attention is necessary.

Increasing Frequency Is a Warning Sign

According to Dr. Rajneesh Kummar, Vice Chairman & Unit Head, Neurology, Max Super Speciality Hospital, Dwarka, one of the most common concerns is increasing frequency.

“If someone who previously experienced occasional headaches starts getting them several times a week or finds that painkillers are needed more often than before, it is worth getting evaluated,” he told HealthandMe.

“People should seek medical attention if they have headaches more than 10 to 15 days a month, if the headaches are getting worse, or if they are beginning to interfere with work, daily activities, or quality of life,” added Dr. Praveen Gupta, Chairman, MAIINS, Marengo Asia Hospitals, Gurugram. He also noted that medication-overuse headaches can result from taking painkillers regularly, leading to a cycle of recurrent pain.

Watch For Changes In Headache Pattern

A change in the pattern of headaches should not be ignored. Dr. Kummar said a headache that feels different from what a person has experienced in the past, particularly after the age of 50, deserves medical attention. Headaches that wake a person from sleep, are worse in the early morning, or are associated with vomiting should also be assessed further.

Dr. Gupta advised prompt medical evaluation for people over the age of 50 who develop a new type of headache. He also recommends seeing a doctor if a person has a history of cancer, a weakened immune system, or develops a headache after a head injury.

Symptoms That Need Immediate Medical Attention

The neurologists highlight several "red flag" symptoms that require urgent medical assessment. They advised immediate consultation if a headache is accompanied by

• weakness on one side of the body,
• difficulty speaking,
• double vision,
• confusion, seizures,
• loss of consciousness,
• Numbness
• balance problems

Not Every Headache Is a Brain Tumor

Dr. Kummar stated that many people worry that every headache is related to a brain tumor or another serious brain disorder. Fortunately, this is rarely the case.

However, persistent or unusual headaches should not be self-diagnosed, and timely consultation helps identify the cause and ensures appropriate treatment before the problem begins affecting quality of life, the expert said.

Early Diagnosis Key

Dr. Gupta told HealthandMe that early diagnosis can help manage common neurological disorders such as migraines, cluster headaches, and chronic tension-type headaches. A thorough history, neurological examination, and imaging studies, when appropriate, can help determine the cause.

The experts emphasize that if headaches are becoming more frequent, changing in patterns, or affecting daily life, it is time to consult a neurologist. Early diagnosis can provide relief, prevent complications, and improve overall quality of life.

Several recent studies suggest that older adults who receive the shingles vaccine may be less likely to develop dementia, a condition affecting more than 57 million people worldwide.

Shingles is a painful viral infection caused by the reactivation of the varicella-zoster virus (VZV), which can remain dormant after chickenpox and later trigger a blistering rash and severe nerve pain.

Shingrix Vaccine And Reduced Dementia Risk

A June 2026 study published in the Annals of Internal Medicine suggests that one in 17 dementia cases could potentially be prevented through shingles vaccination.

Researchers at Brown University found that older adults who received the recombinant shingles vaccine (Shingrix) after a stay in a skilled nursing facility had a 24% lower risk of being diagnosed with dementia over four years than those who were not vaccinated.

The study analyzed Medicare and health records from more than 500,000 adults aged 66 and older admitted to skilled nursing facilities. Researchers compared those who received at least one dose of Shingrix with those who remained unvaccinated.

“A lot of previous studies with similar results focused on an older vaccine,” said study author Kaley Hayes, an assistant professor at Brown University’s School of Public Health.

“This study looks at the newest vaccine only in an older, vulnerable adult population who were not up to date with shingles vaccination and are at a very clear clinical point in care: entering a skilled nursing facility.”

The findings add to growing evidence linking shingles vaccination with a lower risk of dementia.

How Does The Vaccine Protect The Brain?

Researchers believe the vaccine may help protect the brain by preventing shingles and the inflammation caused by the virus.

Shingles can cause a “war zone” of inflammation in the brain, said Dr. Jennifer Pauldurai, the medical director of the Inova Brain Health and Memory Disorders Program in Northern Virginia, NBC News reported.

It’s not that the shingles vaccine itself is a “magic pill,” Pauldurai said.

Rather, the vaccine guards against the disease, which is known to disrupt brain health.

Evidence from Wales, Australia, and Canada

The latest findings add to a growing body of international research.

A study involving more than 282,000 older adults in Wales, published in Nature in 2025, found shingles vaccination was associated with a 3.5% lower absolute risk of dementia over seven years.

Another study of more than 101,000 older adults in Australia, published in the Journal of the American Medical Association in 2025, found vaccine eligibility was associated with a 1.8% lower dementia risk over 7.4 years.

Similarly, a study involving more than 232,000 older adults in Canada, published in The Lancet Neurology in 2026, linked shingles vaccine eligibility to a 2% lower dementia risk over 5.5 years.

Shingles: Early Warning Signs

After a person recovers from chickenpox, the VZV virus remains dormant in nerve cells and can become active again years or even decades later, particularly when the immune system weakens.

Older adults and people with weakened immune systems are at the highest risk of developing shingles.

According to the NHS, shingles often starts with:

• Burning, tingling, itching, or pain on one side of the body
• Headache or feeling generally unwell
• A blistering rash that develops within a few days, most commonly on the chest or abdomen

When To See A Doctor

Seek prompt medical attention if:

• The rash appears on or near the eye
• The pain is severe or rapidly spreading
• You have a weakened immune system
• You are pregnant
• Symptoms are worsening quickly
