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.

As 2025 comes to an end, one thing is clear, this year has been a year of remarkable shifts in how we understand health. This year, there have been breakthroughs, redesigns, and achievements in the healthcare sector, which has changed many lives. Scientists and doctors have pushed their boundaries in ways to save lives, make patients more comfortable and Health and Me lists down 5 such breakthroughs that defined the year 2025.

Reinventing Speculum: The Flower That May Transform Pelvic Exams

Few medical tools have stayed as frozen in time as the vaginal speculum. Cold, metallic, and intimidating, its origin traces back to Dr. James Marion Sims in the mid-19th century, during experiments carried out unethically on enslaved women. Beyond its history, patients have long reported pain, anxiety, and emotional distress linked to it. But this year, a young design team dared to ask what would happen if pelvic exams could feel safe.

Enter Lilium, a flower-inspired speculum created by Delft University engineers Tamara Hoveling and Ariadna Izcara Gual. Made with soft plastic and shaped to bloom like a lily, it opens gently, eliminates the harsh clicking sound, and uses a tampon-like applicator for insertion. Designed to feel familiar and symbolically comforting, Lilium represents a shift toward trauma-informed, patient-first gynecological care—something long overdue.

Zaynich: India Launches Its First New Antibiotic in 30+ Years

For 28-year-old Sahil Mehra from Mumbai, a severe, drug-resistant Pseudomonas infection left his kidneys failing and his doctors nearly out of options. Even last-resort antibiotics couldn’t stop the superbug.

Then came Zaynich, India’s first new antibiotic in more than three decades. Developed by Wockhardt, it combines cefepime, a fourth-generation cephalosporin, with zidebactam, a novel β-lactam enhancer that boosts the drug’s power against tough bacteria. Early reports and trials suggest a 97% effectiveness against drug-resistant Gram-negative bacteria and even a 20% higher cure rate than meropenem in Phase 3 studies. Within four days of receiving Zaynich, Mehra’s condition stabilized—a reminder of why antibiotic innovation is essential in the age of superbugs.

A Powerful Cholesterol-Lowering Pill Could Change Heart Care

High LDL cholesterol remains one of the biggest drivers of cardiovascular disease. While statins help, many people never reach target levels. Injectable PCSK9 inhibitors work well but remain expensive and less accessible.

This year, an experimental daily pill—enlicitide—showed promise of changing that equation. In the Phase 3 CORALreef Lipids trial involving 2,912 adults, enlicitide reduced LDL-C levels by 55.8% at 24 weeks, with post-hoc analysis suggesting reductions up to 59.7%. With a safety profile similar to placebo, enlicitide could become the first oral PCSK9 inhibitor to make potent cholesterol control easier and more widely available.

Zombie Cell: A Longevity Pill From China Claims Life Up to 150 Years

A Shenzhen-based biotech company sparked global debate by claiming it has developed a pill that targets ageing at the cellular level. The pill focuses on clearing “zombie cells”—old cells that refuse to die and trigger inflammation. Made with compounds derived from grape seeds, early animal lab work suggests potential lifespan extension. While far from proven in humans, the idea that such a pill could stretch life to 120–150 years captured the world’s imagination and intensified conversations around longevity science.

The World’s First Single-Dose Dengue Vaccine Gets Approved

With dengue cases hitting record levels globally, Brazil approved the world’s first single-dose dengue vaccine, called Butantan-DV. Developed by the Butantan Institute in collaboration with Wu Xi, it uses a live attenuated virus and is currently approved for ages 12 to 59. Until now, the only dengue vaccine required two doses months apart. This single-shot version could transform dengue prevention, especially in tropical countries facing surges linked to rising temperatures.

Recently the news of Norovirus outbreak in an AIDA cruise that has infected more than 100 guests and crew on board made news. This is the 21st outbreak, as confirmed by the Centers for Disease Control and Prevention (CDC). This case has brought back memories from the Royal Caribbean Cruise outbreak, where 94 out of 1,874 and 4 crew members also were infected by Norovirus.

This virus is also known as the 'rib-cracking' winter virus, which sets it apart from rest of the winter viruses. People who have been sickened by this contagious virus are vomiting explosively, which may make the sufferers to experience a cracking in their ribs, which is where it gets its name 'rib-cracking' winter virus.

What Is Norovirus? What Makes It So Unique?

The virus typically spikes after the holidays, when families gather indoors. However, new data from the Centers for CDC shows this year’s surge has arrived weeks ahead of schedule, and experts say there’s no obvious explanation yet.

According to the CDC, 12.5 percent of norovirus tests came back positive during the week of November 22, nearly identical to the 13 percent positivity rate the week before. Compared to two weeks earlier, infections have jumped by about 25 percent. But the real number of cases is likely far higher, as most people with norovirus never get tested.

Between August 1 and November 13, health officials recorded 153 norovirus outbreaks, more than double last year’s 69 during the same period, and far above the 65 reported in 2023.

The CDC estimates the U.S. sees around 2,500 outbreaks every year. An outbreak is recorded when two or more people fall ill from a suspected or confirmed shared source.

On cruise ships, which are closely monitored by federal agencies, outbreaks have also been climbing. The AIDAdiva, a German vessel currently on a long global route, recently reported a spike in cases. In a statement to USA TODAY, AIDA Cruises said it has increased hygiene measures on board and that infections are already declining.

“Seasonal illness peaks between November and April, and the AIDAdiva report reflects what we’re seeing on land,” the cruise line said.

Why Norovirus Hits So Hard

Norovirus infects roughly 21 million Americans every year and sends about 2 million to hospitals or clinics. It spreads easily through contaminated food, surfaces, shared utensils, or direct contact with an infected person. Even a tiny amount of virus can trigger illness.

Symptoms usually appear within 12 to 48 hours and include nausea, vomiting, diarrhea, stomach cramps, and sometimes fever and chills. The biggest danger is dehydration, which can set in quickly. Severe fluid loss can lead to low blood pressure, reduced organ perfusion, electrolyte imbalances, and in extreme cases, seizures or fainting.

The virus contributes to about 900 deaths in the U.S. annually, mostly among older adults.

Doctors emphasize that hand sanitizers don’t reliably kill norovirus. Frequent handwashing with soap and water is the best protection.

The season’s lowest positivity rate was recorded in early August at 6.5 percent. But with holiday travel and gatherings underway, health officials warn infections are likely to rise.

What Are The Symptoms Of Norovirus And How Long Do They Last?

• Nausea
• Vomiting
• Stomach pain or cramps
• Watery or loose diarrhea
• Feeling ill
• Low-grade fever
• Muscle pain

The symptoms usually begin 12 to 48 hours after your first exposure to the virus and could last from 1 to 3 days. You can, however, continue to shed virus in your stool for several week after your recovery. The shedding could go up for months if you have another medical condition.

Delhi woke up again to a thick layer of smog, with Delhi's AQI hovering over 300 on the Air Quality Index on Thursday morning under "very poor" category. After a long nine-day wait, city's AQI had slipped under "poor" category on Tuesday, but it is again back on the "very poor" category, while on Wednesday, there were strong winds that dispersed the pollutants. Yet the condition of the air quality remains bad.

As a result of this many people are leaving the city, or have at least considered leaving the city.

"I Felt Breathless And Constantly Fatigued"

Nikita Singh, 31, who runs a remote PR boutique agency was living in Delhi on and off for two years because it was two years back when she struggled to breathe during Delhi winters. "The pollution levels were so extreme that I felt breathless and constantly fatigued. That was the first time I seriously questioned whether I could continue living here long-term," she says.

For the first two years, she kept "oscillating". "I would stay in Delhi for work during peak months, then leave when pollution became unbearable, especially from November to January. Every return felt heavier. I had my eyes burning, headaches, chest tightness and a general feeling of 'I cannot do this forever'."

She has now permanent moved away from Delhi to Jodhpur, in Rajasthan, where she works remotely. However, it has not been easy on her. "Emotionally, it was tough because Delhi had become familiar, and my life and work circle were mostly based there," she says. However, thanks to her fully remote work and that fact that she had decided to prioritize her health, she was able to make the move.

She says that Jodhpur offers the cleaner air which she "never felt in Delhi". Her decision to move also came with her family uprooting from Delhi. "My family and I shifted together. AQI was a major trigger. We realized we could not keep exposing ourselves to those levels of pollution year after year," she reveals.

Migration And Pollution: More Delhiites Are Considering To Move Out Of The City

She is not alone, Vikash Makkar, a freelance linguist specialist and a journalist, who had been living in Delhi from the last 12 years, moved back to his hometown in Jamshedpur. "Since October with an unplanned journey, I moved to my hometown and have been living there. It is quite relaxed here as compared to Delhi's ongoing pollution crisis that I had faced," he shares.

29-year-old Riya Baibhawi also uprooted from the city. She had been living in Delhi from last 5 years. She is currently living in Ludhiana, Punjab, and her decision to leave city is also affected by the pollution. Though, it was not easy for her. "It was very tough because it was very difficult to find career opportunities with competitive salaries outside Delhi-NCR. It also required a cut down of my social life, which adversely affected my mental health," she says. She shares that one of her friends, who had been living in Noida for the last 20 years had also moved out as pollution exacerbated her asthma.

Another family, who have been living in Delhi's Karol Bagh for more than two decades now are considering moving out of Delhi. "They are looking for properties outside Delhi where air is cleaner," shares their 26-year-old daughter who now lives in her marital home in Noida.

As per a survey by a consumer insights platform Smytten PulseAI, about 34.6% of the residents surveyed in Delhi NCR have considered to move out of the city due to worsening air. A 2023 study published in the International Journal of Environmental Research and Public Health shows that if the level of PM2.5 increases by 10µg/m3, migrants coming into the city will be reduced by 21.2%. While migration in the city has been ongoing, pollution does show some strains of people moving out of the city.

As per the Air Quality Life Index released by the Energy Policy Institute at the University of Chicago (EPIC), the fine particulate matter or PM2.5 in air will shorten an average Indian's life expectancy by 5.3 years, and in Delhi, it could shorten a person's life span by 11.9 years. However, the Union government has said in the parliament that there is "no conclusive national data to establish a direct correlation between deaths or diseases occurring exclusively due to air pollution". This statement comes at a time when doctors themselves noted a surge in cases due to pollution and have urged people to leave the cities.
