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.

Are you down with fever? Are your symptoms also a little less common from an ordinary cold? Are you also confused between flu and COVID? Then knowing this one symptom could help you set flu apart from COVID. Dr Rupa Parmar, a GP and medical director at Midland Health tells The Mirror, that shortness of breath could be a key symptom that could differentiate between the two.

Dr Parmar highlights that it is a key indicator for COVID. "Shortness of breath is rare in both a cold and the flu, but as COVID more so affects the lungs due to inflammation, it is a common symptom."

The NHS website supports her advice, noting that breathlessness is a symptom more often tied to Covid, not the flu or a common cold. This kind of breathing difficulty is usually associated with infections like Covid or respiratory syncytial virus (RSV).

What Else Could Help You Know If You Have A COVID or Flu?

The nature of your cough could also help you understand different ailments. Dr Parmar said that a cold would produce a mild cough, whereas a flu cough could be more dry. However, with covid, "a cough will be dry and continuous, and many people will cough for more than an hour or have three or more coughing episodes within a day."

If one has lost their sense of smell or taste, then the chances are, this could be COVID. However, this symptom is also present in cold or in a flu.

For people who have Covid, the NHS advises staying home and avoiding contact with others if they or their children have symptoms and either develop a high temperature or feel too unwell to work, attend school, manage childcare, or carry out daily activities. If you are unsure about the cause, it is important to speak with a doctor.

Dr Parmar emphasized: "after all, it is always better to be safe than sorry when it comes to health."

What Is Flu?

The flu is a common respiratory illness that happen from the influenza virus. The common flu symptoms are:

• Fever
• Sore Throat
• Runny Nose
• Fatigue
• Body Aches
• Cough
• Headaches

What Is COVID-19?

As per the US Centers for Disease Control and Prevention (CDC), COVID-19 is a respiratory illness caused by the coronavirus. The common symptoms include:

• Fever
• Cough
• Fatigue
• Headache
• Nausea
• Sore Throat
• Runny Nose
• Loss of smell or taste

COVID-19 could also have some long-lasting symptoms unlike flu or cold, that could seem unrelated to the original infection.

As per the Ohio State University, the most recent COVID variant is XFG or the Stratus variant. Another new variant that causes the 'razor blade' like sore throat is Nimbus.

The symptoms of this new variant includes:

• Congestion
• Cough
• Fever
• Headache
• Sore throat
• Muscle Aches

'Razor blade' Throat

NB.1.8.1 or the Nimbus variant is a subvariant of Omicron, which is a dominant COVID variant since late 2021. Omicron variants tend to cause more throat problems than the other variants seen earlier.

The COVID virus binds to ACE2 receptors. According to WebMD, the cells in your nose and throat contain more ACE2 receptors than those deeper in the lungs, which makes them easier targets for Omicron variants. Once the virus attaches to these receptors in the upper airway, your immune system begins to respond.

Ever since the Trump administration has come to power, sentiments against vaccines have gone up. Many vaccine critiques have been handpicked by the anti-vaxxer HHS Secretary RFK Jr. as health officials. So it is no surprise that now the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices (ACIP) is now recommending that mothers who test negative for hepatitis B should discuss the need for the vaccine with their doctors. If parents choose to delay the birth dose, the first shot should be given at no earlier than two months of age. This is dropping the longstanding hepatitis B vaccine guideline that stated that every newborn receive the first dose of the hepatitis B vaccine shortly after birth. This recommendation, in place since 1991, was reversed on December 5 after a key CDC advisory committee voted to change the policy.

This committee was appointed by Health and Human Services Secretary Robert F. Kennedy Jr., who dismissed all 17 previous members earlier this year. The shift in policy has triggered wide debate, especially in the medical community, because it overturns one of the longest standing infant vaccination guidelines in the United States.

Below are some of the claims made by the panel, both sides, who debated the vaccine's need or unimportance for all infants.

Hidden Hepatitis B Infections Make Risk Hard to Judge

Claim: Several ACIP members questioned whether babies considered “low risk” truly need a hepatitis B shot at birth. But hepatitis B is not always easy to detect or trace.

The virus spreads through bodily fluids such as blood, semen and vaginal fluids. It is also extremely resilient and can survive on surfaces for up to a week. Even tiny amounts of dried blood from everyday items like razors, toothbrushes or nail clippers can carry the virus.

Hepatitis B often has no symptoms for years. The CDC estimates that 640,000 adults in the United States live with chronic hepatitis B, and half do not know they are infected. This means that even if a mother tests negative during pregnancy, her newborn can still be exposed through family members or other caretakers. Before universal birth-dose vaccination began, only half of infected children under age ten had contracted the virus from their mothers at birth.

Because so many people are unaware of their infections, determining true risk is complicated.

The Vaccine Protects the Most Vulnerable: Newborns

Claim: Some committee members suggested that vaccinating all newborns mainly protects adults or others at higher risk.

That claim is misleading. The primary purpose of giving the shot at birth is to protect infants, who face the most severe long-term consequences of infection.

Hepatitis B attacks the liver. If an infant becomes infected, there is a very high chance the disease will progress into a chronic lifelong condition. About a quarter of those children eventually die prematurely from liver failure or liver cancer. While treatments exist to reduce complications, there is no cure.

Dr. James Campbell, a pediatric infectious disease specialist at the University of Maryland, reminded the committee that the vaccine strategy transformed public health outcomes. “We used to have 18,000 or 20,000 kids born with this every year, and a quarter of them would go on to develop liver cancer. We now have almost none,” he said.

Falling Infection Rates Show Vaccines Worked

Claim: Hepatitis B infections fell sharply after the birth-dose recommendation took effect. Before vaccination became routine, up to 300,000 Americans were infected annually. About 20,000 of those were children.

Today, total annual cases have dropped to around 14,000. Among people under 19, chronic infections have reached extremely low levels. In 2022, the CDC documented only 252 new cases in this age group.

ACIP member Dr. H. Cody Meissner, who voted against changing the policy, argued that declining numbers do not justify easing precautions. “It is a mistake to say that because we are not seeing much disease, we can change the schedule,” he said. “If we do, hepatitis B infections will come back.”

The United States Is Not an Outlier

Claim: Some committee members compared U.S. policy to countries such as Denmark, which does not vaccinate all newborns.

However, the United States is far from alone in recommending a universal birth-dose. According to CDC data from September 2025, 116 out of 194 World Health Organization member countries recommend hepatitis B vaccination at birth.

Denmark does not include hepatitis B in its standard childhood schedule, but it has a centralized national health system, higher prenatal screening rates and less fragmented medical records. The United States lacks these structural advantages, which makes relying solely on maternal testing more challenging.

A senior British cardiologist has shared a clear two-word tip that he says can make a real difference to your blood pressure. Dr Amir Khan recently explained this advice while outlining five simple habits that can naturally bring hypertension under control, particularly during the winter months when heart risks tend to rise.

India continues to struggle with a heavy hypertension burden. Roughly one in three adults is estimated to have high blood pressure, yet many remain unaware of their condition, and even fewer manage it well. Doctors often warn that this lack of awareness, combined with poor control and gaps in long-term care, leads to serious complications such as heart attacks, strokes, and kidney disease. Since hypertension usually comes without symptoms, it has long been known as a silent killer.

Dr Khan highlights that a few lifestyle tweaks can go a long way, and his biggest message is built around a simple two-word mantra: “get moving”. He explained on Instagram that regular physical activity keeps blood vessels flexible and supports healthy blood flow. His advice is to pick any form of movement you genuinely enjoy and make it part of your routine.

How movement actually helps

Exercise reduces blood pressure by strengthening the heart, improving circulation, and reducing the strain on arteries. A stronger heart pumps blood more efficiently, which lowers the force exerted on blood vessel walls. Physical activity also opens up small blood vessels, helps manage weight, and reduces inflammation and stress hormones. All of these support healthier vascular function and better overall pressure control.

Doctors recommend a mix of aerobic activity, such as brisk walking, swimming, or cycling, along with strength training to support long-term heart and metabolic health.

Other helpful changes, according to Dr Khan

While movement is his main message, Dr Khan also lists four additional habits that support healthier blood pressure levels.

Reduce salt intake

He explains that those with high blood pressure need to be especially mindful of hidden salt. Adults should ideally stay around six grams a day, which is about a teaspoon. Much of this is already present in packaged or restaurant foods. Using herbs, spices, and fresh ingredients can help bring the total down.

Add more potassium-rich foods

Dr Khan encourages increasing potassium intake because it helps the kidneys flush out excess sodium. Foods rich in potassium include bananas, tomatoes, spinach, carrots, and kiwi. Adding these regularly can make a noticeable difference.

Avoid smoking and alcohol

He stresses that avoiding cigarettes and limiting alcohol is key for heart health. Smoking damages blood vessels and raises blood pressure, while alcohol can worsen both pressure and weight control.

Maintain a healthy weight

Keeping weight in a healthy range reduces strain on the heart and helps blood vessels function more efficiently. It also improves circulation and reduces the substances that cause vessels to tighten.

Dr Khan’s message is simple. Small and consistent lifestyle choices can noticeably lower blood pressure, and starting early makes a significant difference.
