Cold sores are a common and often frustrating skin issue. While they may look like harmless blisters, cold sores are actually caused by the herpes simplex virus (HSV).

What Causes Cold Sores?

Cold sores are caused by the herpes simplex virus (HSV), which comes in two types: HSV-1 and HSV-2.

HSV-1 is the primary cause of cold sores, usually appearing around the mouth.

HSV-2 generally causes genital herpes but can also lead to cold sores.

While the appearance of cold sores caused by both HSV-1 and HSV-2 can look similar, their locations tend to differ. However, it is possible for HSV-1 to cause sores on the genitals and for HSV-2 to appear on the mouth.

How Do Cold Sores Spread?

Cold sores are highly contagious and can spread easily. The virus can be passed on through:

• Kissing or skin contact
• Sharing food, drinks, or cosmetics (such as lip balm)
• Oral sex, which can spread both cold sores and genital herpes

Even when a cold sore isn’t visible, the virus can still be spread through close contact. This makes prevention and management key to reducing outbreaks and the risk of infecting others.

Once someone contracts HSV, it stays in the body for life. While the virus remains dormant most of the time, it can reactivate and cause new sores, especially during periods of:

• Stress
• Illness
• A weakened immune system

Unfortunately, there’s no cure for the herpes virus, but the symptoms can be managed.

Symptoms of Cold Sores

Cold sores don’t just appear out of nowhere. Before the sore is visible, you may notice a tingling or burning sensation around the lips or face, which can occur several days before the sore forms. This is the best time to begin treatment to shorten the outbreak.

When a cold sore does appear, it often looks like a red, raised blister filled with fluid. The blister can be painful to touch, and there may be more than one. Cold sores usually last around two weeks and are contagious until they crust over and heal.

The Five Stages of a Cold Sore

Cold sores go through distinct stages as they develop and heal:

• Tingling and itching: You may feel these symptoms about 24 hours before the blister appears.
• Blisters: Small, fluid-filled blisters form, typically around the mouth.
• Bursting: The blisters burst and form painful sores.
• Scabbing: The sores dry out, scab over, and may itch or crack.
• Healing: The scab falls off, and the cold sore heals.

Risk Factors for Cold Sores

Certain factors can trigger the reactivation of HSV, leading to cold sores. These include:

• Infection, fever, or cold
• Sun exposure
• Stress
• Menstruation
• Dental work or injury
• Weakened immune system due to conditions like HIV/AIDS, eczema, or chemotherapy

Managing and Treating Cold Sores

There’s no cure for cold sores, but several treatments can ease the symptoms and help manage outbreaks.

Topical Ointments and Creams

Over-the-counter antiviral creams like docosanol (Abreva) or prescription ointments like penciclovir (Denavir) can help reduce the duration of an outbreak, especially if applied at the first sign of a cold sore.

Oral Medications

Prescription antiviral medications like acyclovir, valacyclovir, and famciclovir can also help, particularly for people who have frequent or severe outbreaks. Your doctor may recommend taking these medications regularly to prevent future outbreaks.

Home Remedies

There are also some home remedies that may provide relief, such as:

• Applying ice or a cold washcloth to the sore
• Using aloe vera gel or lemon balm lip balms
• Applying petroleum jelly to ease discomfort

Canker Sores vs. Cold Sores: What's the Difference?

While cold sores and canker sores may seem similar, they are quite different:

Cold sores are caused by the herpes virus, appear around the mouth, and are contagious.

Canker sores are not contagious and appear as ulcers inside the mouth or throat.

Preventing the Spread of Cold Sores

To avoid spreading cold sores:

• Wash your hands frequently
• Avoid close contact with others during an outbreak
• Don’t share food, drinks, or personal items like lip balm

Cold sores can be a persistent issue, but with proper care and management, you can reduce the frequency of outbreaks and prevent spreading the virus to others.

During the festive months, overindulgence in celebrations can trigger holiday heart syndrome (HHS), a potentially serious yet largely preventable set of heart-related symptoms that tend to rise during this time of year. Most people recover within a day, but HHS can occasionally lead to stroke, heart attack, or other serious complications, according to the Cleveland Clinic. As the holiday season approaches, let’s explore what holiday heart syndrome is, its symptoms, and how to prevent it.

What Is Holiday Heart Syndrome?

First identified by a US physician in 1978, holiday heart syndrome describes irregular heartbeats that occur after binge drinking during the festive season. Research from the University of South Australia shows that alcohol consumption increases by 70 per cent in December compared to other months, while iSelect data predicts Australians may consume around 58 million standard drinks per day during the month. With numbers like these, some caution is warranted.

Atrial fibrillation (AFib) is the specific irregular heartbeat seen in HHS. It occurs when the heart’s upper chambers contract or quiver in a chaotic pattern, which can cause blood to pool in the atrium and form clots. If these clots enter the bloodstream, they can travel to the brain and trigger a stroke.

What Are the Symptoms of Holiday Heart?

Symptoms can include fatigue, dizziness, shortness of breath, anxiety, weakness, confusion, sweating, faintness, unusual tiredness during exercise, rapid or irregular heartbeat, and sensations like fluttering, thumping, pressure, or chest pain.

Dr Mariann R. Piano, Nancy and Hilliard Travis Professor of Nursing at Vanderbilt University School of Nursing, warns, “The scary thing is that people may not notice any symptoms, which makes it a particularly dangerous arrhythmia.”

How Can Drinking Lead to AFib?

Researchers are still investigating exactly how alcohol triggers AFib and how much intake increases the risk. A 2020 study found that people who usually drank at least 10 alcoholic beverages a week lowered their risk of holiday heart syndrome by reducing alcohol consumption. Another study confirmed that eliminating alcohol significantly decreases the chances of developing AFib.

How To Try to Avoid Holiday Heart Syndrome

The Australian Alcohol Guidelines recommend that healthy adults limit alcohol to no more than 10 standard drinks per week to reduce risk.

Experts like Kistler suggest that people with existing heart arrhythmias either abstain or stick to “up to three standard drinks a week.” Drinking mindfully, reducing overall consumption, and staying well hydrated can also help protect your heart.

Tips To Keep Your Heart Healthy During Holidays

• Eat smaller, balanced meals and avoid heavy late-night feasts.
• Limit alcohol intake and stay hydrated.
• Continue regular medications without interruption.
• Stay warm and avoid sudden exposure to cold temperatures.
• Maintain light physical activity and avoid strenuous exertion in the early morning.
• Manage stress by taking breaks, sleeping adequately, and avoiding overexertion during travel or celebrations.
• Seek medical help immediately if you experience chest discomfort, unusual fatigue, breathlessness, or palpitations.

Walking into a clinic or diagnostic centre is never easy. You carry your worries, discomfort, or questions, hoping the people there will guide you with care. Most medical professionals honour that trust. But when someone crosses a line—when a touch feels sexual, unnecessary, or wrong, the sense of safety disappears instantly. It’s not just awkwardness; it’s a violation in a place where you should feel protected.

A recent case in Bengaluru shows just how real this is. A radiologist at a private diagnostic centre was booked for allegedly sexually harassing a woman during a routine scan. When she spoke up, he reportedly threatened her and used abusive language to intimidate her. She had come for an abdominal scan with her husband, expecting a routine procedure, not harassment.

What stays with you after such an experience is not just the shock, it’s the feeling that your trust has been broken. That moment cannot be taken back. What you can do, however, is make sure the system is held accountable, so no one else has to face the same harm.

This raises an important question. Are there legal protections in India that support patients in such situations? To understand this better, we spoke with Anisha Mathur, Founding Partner at Shepherd Law Associates.

What Does India’s New Criminal Law Say?

India’s updated criminal code, the Bharatiya Nyaya Sanhita (BNS), which replaces the Indian Penal Code, is clear that sexual misconduct is a crime no matter where it occurs. Clinics, nursing homes, physiotherapy rooms, diagnostic centers, and even home-based procedure spaces fall under its scope. If a staff member touches a patient in a way that is not medically necessary, ignores privacy during an intimate examination, makes the patient feel uncomfortable, or reveals sexual intent, the act may be treated as a criminal offence.

According to Anisha Mathur, “Unwanted or unnecessary touch can amount to sexual harassment. Any contact that has sexual intent and is not medically justified may be treated as assault with sexual intent. The context, the nature of the procedure and the patient’s consent are all considered while determining this. A medical setting is not a loophole. A uniform is not immunity. Misconduct is misconduct.”

Actions To Take When A Sexual Misconduct Takes Place In A Medical Setting

Once you recognise that the behaviour is inappropriate, you have every right to act. Anisha Mathur suggests the following steps:

Step 1: Pause the interaction

Say you want the procedure to stop. You may ask for a female attendant or any other staff member to be present.

Step 2: Move to a safer area

Walk to the waiting room or any open space within the facility.

Step 3: Note down details

Record the time, the room, what happened and who was involved. Even small details may matter later.

In a larger hospital or diagnostic chain, go to the administration or patient desk and request that your complaint be put in writing. Many such establishments have an Internal Committee (IC) under the Prevention of Sexual Harassment (PoSH) Act, 2013.

If you are in a smaller clinic, nursing home or any space without a complaint system, call 100 or 112. When the officials arrive, ask them to record your statement. If you can reach a lawyer, it helps, because early legal guidance prevents confusion and intimidation.

Anisha adds, “Authorities may ask whether you want a Medico-Legal Certificate (MLC) examination to document physical signs, which is normal. You can request a trusted friend or family member to be with you. You do not need to know the law in that moment. You only need to protect yourself, the law will support you. If something feels wrong, it is wrong. You are allowed to stop the procedure immediately.”

Legal Actions You Can Take After the Incident

Once the initial shock settles, several routes are available:

• Filing a criminal complaint (FIR)

• Requesting disciplinary action from the medical council

• Filing a civil or consumer case if the establishment failed in its duty

Anisha Mathur stresses that both the individual staff member and the institution can be held responsible. This is often how meaningful change begins.

Can a Patient File a Complaint Anonymously?

In many hospitals and clinics, internal systems allow anonymous complaints. For police cases, your identity is needed for investigation, but Indian law protects your privacy strictly. Your name cannot be disclosed publicly. Any attempt to threaten or silence you becomes a separate offence.

Are Hospitals Expected To Have Safety Measures For Patients?

Every medical facility is expected to follow basic standards that protect patients. According to Anisha, these include:

• Clear consent before intimate examinations

• A female attendant upon request

• Privacy safeguards during procedures

• Staff training on professional boundaries

• A channel for patients to raise concerns

If these were ignored or missing, it strengthens the patient’s case. These protections are not optional. They are part of the provider’s legal duty.

Consequences For Staff Who Violate Boundaries

Sexual misconduct by medical staff is treated as seriously as misconduct in any other setting, sometimes more so because patients are vulnerable and rely on the professional’s judgment. Anisha explains, “Under BNS, the staff member can face criminal prosecution leading to arrest, fines, suspension or dismissal, and loss of professional license. Courts have repeatedly said that misusing power in a caregiving role makes the offence more serious, not less.”

Being in a medical space should never turn into an experience marked by fear. Any form of sexual misconduct during care is a violation of your dignity at a moment when you are already exposed and trusting. What happened cannot be undone.

Anisha Mathur stresses this and says, “Your voice can bring accountability. Your action can protect someone else. Your dignity remains yours, and the law stands with you.”

The world is battling a 'very tough' flu season this year. Already there was super flu, the mutated clade K, and now reports of three children from Ottawa and Eastern Ontario dying due to flu-related complications in the past two weeks have come up. This is the result of influenza A. This strain is currently circulating widely and affecting children more severely than ever.

What Is So Unique About Influenza A?

As per the National Institutes of Health, US, influenza viruses that contains single-stranded RNA that are classified into three types: A, B, and C. Type A and B cause annual epidemics and even pandemics, while type C is a less common disease.

As per the Centers for Disease Control and Prevention (CDC), Influenza A viruses are descendants of the 2009 H1N1 pandemic virus that emerged in the spring of 2009 and caused a flu pandemic. These viruses, scientifically called the "A(H1N1)pdm09 virus," and more generally called "2009 H1N1," have continued to circulate seasonally since 2009 and have undergone genetic and antigenic changes.

Influenza A(H3N2) viruses also change genetically and antigenically. Influenza A(H3N2) viruses have formed many separate, genetically different clades in recent years that continue to co-circulate.

It is a fast-spreading respiratory virus responsible for seasonal flu outbreaks and, at times, global pandemics. It changes quickly through genetic shifts, which makes new strains harder to predict and control. The virus is grouped based on surface proteins called hemagglutinin and neuraminidase, with H1N1 and H3N2 among the most common strains in circulation. It spreads mainly through coughs, sneezes, or close contact and often comes on suddenly, causing fever, cough, body pain, and extreme tiredness. In some cases, it can lead to serious complications, especially in vulnerable groups.

Is There A Difference Between H1N1 and H3N2 Virus?

Both are a type of influenza A virus that causes seasonal flu. However, while H3N2 changes its form regularly, which makes it harder for our immune system to fight it off, H1N1 is also known as swine flu. It is now a regular seasonal flu virus that comes back every year.

How to differentiate between the two in terms of symptoms?

H3N2 Symptoms

• High fever (often above 101°F)
• Severe body aches and muscle pain
• Extreme tiredness that lasts longer
• Dry cough that can be persistent
• Headache
• Sore throat
• Runny or stuffy nose
• Loss of appetite
• Nausea (especially in children)

H1N1 Symptoms

• Fever (usually moderate)
• Body aches (less severe than H3N2)
• Cough
• Headache
• Sore throat
• Runny nose
• Stomach problems (more common)
• Diarrhea and vomiting (especially in children)
• Chills and sweating

The recovery time of any influenza could last up to 5 to 14 days, the key is to monitor breathing patterns and avoid over medication.

What Is The Best Line Of Defense?

This year, the flu is hitting hard everywhere. While winter flu cases are not uncommon, the virus is changing every day, which causes it to be more severe than ever. The best line of defense in this case is vaccination. Experts have suggested that despite mutation, vaccine provides the best defense.

“The flu vaccine may not always prevent infection, but it significantly reduces the risk of severe illness, hospitalization, and complications,” officials said. They added that the vaccine takes about two weeks to become fully effective, making early vaccination crucial ahead of the holiday season, when virus spread typically increases.
