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.

Breastfeeding is important not only for babies' health and nutrition but also for protecting mothers from serious diseases, the World Health Organization (WHO) said.

It urged governments to strengthen access to services and interventions that support breastfeeding as part of World Breastfeeding Week, observed annually from August 1–7.

The 2026 theme, "Breastfeeding for a Sustainable Start in Life: Strengthen What Works," focuses on tracking progress, evaluating impact, and scaling proven approaches that improve breastfeeding outcomes.

Breastfeeding Could Save Hundreds of Thousands of Lives

"Scaling up breastfeeding could prevent almost 400,000 child deaths and around 140,000 maternal deaths each year," said UNICEF Executive Director Catherine Russell and WHO Director-General Dr. Tedros Adhanom Ghebreyesus in a joint statement.

"Every US$1 invested in breastfeeding promotion generates an estimated US$59 in economic returns through lower health-care costs, improved cognitive development, higher educational attainment, and increased lifetime earnings," they added.

Health Benefits for Babies and Mothers

The experts noted that breastfeeding is one of the simplest and most powerful ways to protect a child's health. It provides infants and young children with essential nutrition, boosts immunity, helps protect against serious illnesses, and supports cognitive development.

For mothers, breastfeeding also offers significant health benefits by reducing the risk of noncommunicable diseases such as breast and ovarian cancers, and type 2 diabetes.

Global Breastfeeding Rates Have Improved

The WHO said breastfeeding rates have improved globally due to sustained investments in policies and programs supporting mothers and families.

Exclusive breastfeeding during the first six months increased from around 37 per cent in 2012 to more than 47 per cent today. Over the past five years, the prevalence of breastfeeding up to two years of age has risen from 38 per cent to 50 per cent.

Progress Remains Uneven

Despite these gains, the WHO said many countries continue to lag behind global targets.

"Coverage of services supporting breastfeeding remains low, policies are inconsistently enforced, and service quality is often inadequate, especially in low-income, fragile, and humanitarian settings," the WHO said.

The agency noted that cost-effective interventions include skilled breastfeeding support within health systems, community-based counselling, maternity protection policies, and protection from the exploitative marketing of commercial milk formulas.

WHO, UNICEF Call for Stronger Support

WHO and UNICEF called on governments, health systems, workplaces, communities, civil society organizations, and families to strengthen the "Warm Chain of Support" for breastfeeding.

During World Breastfeeding Week, the agencies urged countries to:

• Strengthen health systems to provide quality breastfeeding support for mothers and newborns.
• Expand community-based counselling and peer support programs.
• Fully implement and enforce the International Code of Marketing of Breast-milk Substitutes.
• Invest in paid maternity leave and supportive workplace policies.
• Integrate breastfeeding interventions into antenatal, perinatal, and postnatal health-care services.
• Sustain breastfeeding support in humanitarian and fragile settings.

"Breastfeeding is vital. By investing in proven solutions, we can give every child the best possible start in life and ensure every mother gets the care and services she needs," the agencies said.

A new study published in The Lancet Regional Health–Southeast Asia has found that India accounts for 68% of all childhood cancer cases in the SAARC region.

While the country's large child population contributes to the high numbers, experts say underdiagnosis and incomplete cancer registration may mean the actual burden is even greater.

An international team of researchers, including from the US, India, and Canada, estimated that nearly 37,700 children aged up to 14 years were diagnosed with cancer across South Asia in 2022, with 17,700 deaths reported. India alone accounted for an estimated 25,939 cases and 12,028 deaths.

The researchers noted that because cancer registration remains incomplete, particularly in rural areas, the true number of childhood cancer cases in India could exceed 50,000 annually.

India's Large Child Population Drives Numbers

India is home to more than 380 million children, accounting for nearly 69% of the child population in the SAARC region. This naturally contributes to the country's higher share of childhood cancer cases and deaths.

However, experts emphasize that population size is only part of the explanation. Delayed diagnosis, limited access to specialized treatment, and gaps in cancer registration continue to affect both disease estimates and patient outcomes.

Leukemia Most Common Cancer

Dr. Narendra Agrawal, a leading Hematologist and Bone Marrow Transplant Physician and Senior Consultant and Unit Head of Haemato-Oncology at Rajiv Gandhi Cancer Institute & Research Centre, told HealthandMe that childhood cancer remains a major public health concern in India.

"Current estimates suggest that around 70,000–80,000 children and adolescents develop cancer each year, although the exact number remains uncertain due to expanding cancer registration systems". The most common childhood cancers in India include:

• Leukemia
• Lymphomas
• Brain tumors
• Bone tumors

What Causes Childhood Cancer?

Unlike many adult cancers, most childhood cancers do not have a clearly identifiable or preventable cause. Dr. Agrawal explained that, in most children, cancer develops because of genetic changes that occur during early development. These changes are usually not linked to lifestyle factors or inherited from parents.

Recognized Risk Factors

Although the causes of most childhood cancers remain unclear, some well-established risk factors include:

• Ionizing radiation: High-dose exposure before birth or during childhood increases the risk of leukemia and certain other cancers.
• Genetic syndromes: Conditions such as Down syndrome, Li-Fraumeni syndrome, and neurofibromatosis increase susceptibility to specific childhood cancers.
• Certain infections: Epstein–Barr virus (EBV) is associated with some lymphomas, HIV increases lymphoma risk, and chronic hepatitis B infection raises the risk of liver cancer.
• Environmental and parental exposures: Tobacco smoke, certain chemicals, pesticides, and some occupational exposures have been investigated as possible risk factors, although evidence remains inconclusive.

Challenges Beyond Disease Burden

Dr. Agrawal said India's substantial childhood cancer burden is largely driven by its population size. However, improving outcomes requires addressing several systemic challenges.

Key issues include:

• Delayed diagnosis
• Limited access to specialized pediatric oncology services in some regions
• Treatment abandonment
• Incomplete cancer registration

A small spot on a lung CT scan can be alarming, with many people immediately fearing the worst. However, doctors say that a lung nodule is a common finding and, in most cases, is not cancer. On , specialists explain what lung nodules are, why they appear, which features may warrant closer evaluation, and how timely diagnosis can help detect serious conditions early and prevent unnecessary anxiety.

Dr. Gyanendra Agrawal, Senior Director - Interventional Pulmonology & Pulmonary Intensive Care, Max Super Speciality Hospital, Noida, told Health and me, "It is essential to talk about one of the most serious concerns of the patients who have undergone a CT scan on World Lung Cancer Day, oftentimes linked with the description of a spot/nodule found in the lungs. Some people see this term in the report and are gripped by fear; unfortunately, not all spots in the lung signify lung cancer."

According to Dr. Vinayak Maka, Senior Oncologist, Department of Oncology, Ramaiah Memorial Hospital, "A lung nodule is a small, round or oval-shaped growth in the lung, typically less than 3 cm in size, most often discovered incidentally during a chest X-ray or CT scan done for an unrelated reason."

Notably, nodules are extremely common; many people carry one without ever knowing it, and without it causing any symptoms. They can form due to a wide range of causes, including old infections, inflammation, scar tissue, or benign growths. In a smaller proportion of cases, a nodule may represent an early cancerous growth, which is why understanding its characteristics matters.

"A lung nodule finding on a CT scan often triggers panic, but the reality is reassuring: over 95% of lung nodules are benign, arising from old infections, scars, or inflammation. Still, understanding when a nodule warrants concern can be lifesaving." Dr. Vinayak Maka added.

What Determines Risk?

Size is the key factor when assessing a lung nodule, alongside the patient's overall health. Nodules smaller than 6 mm have a very low cancer risk (under 1%) and usually only need routine follow-up. Those measuring 6–8 mm carry a slightly higher risk (1–2.5%) and are typically monitored with a repeat CT scan after 6–12 months.

On the other hand, Dr. Shyam Krishnan, Lead Consultant, Clinical & Interventional Pulmonology, CMRI (CK Birla Hospitals), Kolkata, told Health and me, "This World Lung Cancer Day, my message is simple. Do not ignore the shadow on your scan — but do not be paralysed by it either. Get it checked by people who can tell you exactly what it is. In lung cancer, a precise and early answer is the single most powerful thing we have. And that answer is now closer, gentler, and faster than most people realise."

Finding a lung nodule does not automatically mean a diagnosis of lung cancer. Experts stress that the size, appearance, and a person's medical history all play a role in determining the next steps.
