If you are in Delhi-NCR and have recently been coughing, sneezing, or running a fever, you are not alone. A recent LocalCircles survey shows that 69 per cent of households in the region currently have one or more members experiencing Covid, flu, or viral fever-like symptoms.

The report, titled “Viral illnesses soar in Delhi NCR as 69% households surveyed confirm one or more members experiencing symptoms,” highlights a sharp increase from 54 per cent in March 2025 to 69 per cent now. Here’s a closer look at the H3N2 virus, its symptoms, and the precautions you should take.

What Is the H3N2 Virus?

H3N2 is a subtype of the influenza A virus. According to the World Health Organization (WHO), it causes seasonal flu outbreaks and mutates frequently, which makes it more challenging to manage than other flu strains.

The virus spreads rapidly through droplets from coughing, sneezing, or even talking. It can also spread when a person touches contaminated surfaces and then touches their face. H3N2 can be particularly dangerous for young children, the elderly, pregnant women, and people with weakened immune systems. The Centers for Disease Control and Prevention (CDC) warns that in these groups, H3N2 can lead to serious complications such as pneumonia, bronchitis, and hospitalization.

Symptoms of H3N2 Virus to Watch ForAccording to the Indian Council of Medical Research (ICMR), H3N2 has been the predominant strain causing the recent surge in flu cases across India. Data from hospital admissions for Severe Acute Respiratory Infection (SARI) indicates that 50% of these patients tested positive for H3N2.

Common symptoms include:

  • Sudden high fever (often above 38–39°C) with chills
  • Persistent cough and sore throat
  • Severe fatigue, weakness, and body aches
  • Headache and nasal congestion
  • In children: nausea, vomiting, or diarrhea
Many patients report fever lasting more than 5–7 days, with cough persisting even after other symptoms subside.

Precautions Against H3N2 Virus

Prevention is key, and National Institute of Health recommend the following measures:

  • Wash hands regularly with soap and water for at least 20 seconds
  • Wear masks in crowded or poorly ventilated areas
  • Cover your mouth and nose when coughing or sneezing; dispose of tissues immediately
  • Avoid close contact with sick individuals; isolate infected household members if possible
  • Keep living spaces well-ventilated
  • Maintain good nutrition, hydration, and adequate rest
  • Consider the seasonal influenza vaccine, which often protects against H3N2 strains—especially important for children, the elderly, and those with chronic illnesses

H3N2 in the United States

The 2017–18 flu season in the U.S. was particularly severe, with the CDC estimating that 41 million people experienced flu symptoms, including 52,000 deaths. However, as of now, no significant H3N2 cases are being reported in the U.S.

The WHO continues to stress that vaccination is the most effective way to prevent influenza, particularly for high-risk groups and their caregivers.

‘Smoking Helped Me Lose Weight’—But It May Be Raising Your Type 2 Diabetes Risk

Updated Sep 15, 2025 | 09:00 PM IST

SummarySmoking is a habit that is much more common than you may realize. Although many people know that it can cause lung cancer, they chose to take the risk. However, that is not the only risk you are putting your body in when you smoke. Your smoking can trigger a type of diabetes. Here’s how.

If you smoke or around people who smoke, you may have heard them exclaim how smoking makes them lose appetite and helps them lose weight. If you are a person who struggles with weight gain, this logic may appeal to you, however, it could affect you in a completely different way than you realize. Type 2 diabetes is more common than you may realize, more than 38 million Americans have diabetes and 90% to 95% of them have type 2 diabetes (CDC data).

One of the best ways to contain type 2 diabetes is by losing weight. If you think that smoking could be a way to lose this weight, you may want to re-think that.

New research suggests that smoking increases the risk of developing type 2 diabetes, regardless of the specific subtype a person might have. This study, which combines data from Sweden, Norway, and Finland, also found that people with a genetic risk for diabetes are even more vulnerable to the negative effects of smoking.

What Are The Sub-Types of Type 2 Diabetes?

Type 2 diabetes is not a one-size-fits-all condition. Researchers have proposed that it can be broken down into four distinct subtypes, each with different characteristics and health risks.

  • SIRD (Severe Insulin-Resistant Diabetes): The body's cells do not respond well to insulin.
  • SIDD (Severe Insulin-Deficient Diabetes): The body does not produce enough insulin.
  • MOD (Mild Obesity-Related Diabetes): Linked to obesity, often starting at a younger age.
  • MARD (Mild Age-Related Diabetes): Develops later in life.
While the severity and complications differ among these subtypes, it was previously unclear if they shared the same risk factors.

How Does Smoking Affect Diabetes?

The study, which analyzed data from over 3,300 people with type 2 diabetes and almost 3,900 healthy individuals, found a strong connection between smoking and all four diabetes subtypes.

Increased Risk for All Subtypes

People who had ever smoked (current and past smokers) were at a higher risk of developing any of the four diabetes subtypes compared to non-smokers.

What Diabetes Was Linked To Smoking?

The connection was particularly strong for SIRD, the type of diabetes where the body resists insulin. Smokers were more than twice as likely (2.15 times) to develop SIRD than non-smokers. Smoking was also responsible for over a third of all SIRD cases in the study.

Heavy Smoking Increases Risk Further: Heavy smokers (those who smoked at least 20 cigarettes a day for 15 years) had an even higher risk for all four subtypes, with the risk for SIRD being 2.35 times higher than for non-smokers.

Smokeless Tobacco: The study also found a link between heavy use of snus (a smokeless tobacco product) and an increased risk of the more severe diabetes subtypes (SIRD and SIDD) in men.

Could Your Genetics Put You At Higher Risk of Diabetes?

The research also explored how smoking affects people who are already at a high genetic risk for diabetes. The findings showed that heavy smokers with a genetic predisposition for poor insulin production were particularly vulnerable. For example, a heavy smoker with a high genetic risk for impaired insulin secretion was over three times more likely (3.52-fold) to develop SIRD compared to a person without these risk factors.

The study's overall conclusion is clear: smoking raises the risk of type 2 diabetes, regardless of which subtype a person is prone to developing.

Higher Dose Of Weight Loss Medicine Is Not Only Safe, But Could Also Be Better For Weight Loss In Obese Adults

Updated Sep 15, 2025 | 05:18 PM IST

SummaryDespite how weight loss medication may look like a magic pill, it has many setbacks that you should consider before you take it. Questioning how effective it is, researchers found that a dose higher than the basic prescription people get for this medication may work better. Here’s what you need to know.

Recently weight loss medication has gained a lot of popularity. Many people are getting these medicines prescribed in order to lose weight; however, it is not as straightforward of a process as we think it is. There are various aspects of it you should know about before you start taking the medication. One of which is that one needs to take it consistently even after they lose weight because they may gain weight back. How effective the medicine is on you also matters.

Whenever it comes to new medication that can majorly alter a person’s lifestyle physique as well as how their body functions, like Ozempic, one has to be very careful with the doses.

While too much of it can trigger health issues, less of it may not give you the desired effect. So, what should a person do when they are not seeing the results they want? A new study shows that a higher dosage than what we currently have approved, could actually help with better weight loss in obese adults.

An international study has found that a higher weekly dose of the drug semaglutide (7.2 mg) is safe and more effective for weight loss than the currently approved dose (2.4 mg). The findings, published in The Lancet Diabetes & Endocrinology, suggest that this higher dose could be a new and powerful option for adults living with obesity, including those who also have type 2 diabetes.

How Much Semaglutide Dosage Helped People Lose Weight?

In adults who do not have diabetes, a 7.2 mg weekly dose of semaglutide led to a significant average weight loss of almost 19%. This is a notable improvement over the 16% weight loss seen with the standard 2.4 mg dose and a 4% loss in the placebo group (who received a dummy treatment).

Almost half of the participants on the higher dose lost 20% or more of their body weight, with about one-third losing at least 25%. These participants also saw improvements in their waist circumference, blood pressure, blood sugar, and cholesterol levels, which are all important for reducing health risks related to obesity.

For adults with obesity and type 2 diabetes, the 7.2 mg dose also showed better results. These individuals experienced an average weight loss of 13%, compared to 10% with the 2.4 mg dose and 3.9% with the placebo. The higher dose also led to significant reductions in blood sugar levels and waist size.

Is It Safe To Take More Semaglutide?

The study found that the higher dose of semaglutide was safe and well-tolerated overall. The most common side effects were gastrointestinal issues, like nausea and diarrhea, and some tingling sensations. However, most of these side effects were manageable, resolved on their own over time, and did not cause people to drop out of the trial. The researchers did not find any increase in serious health problems or severe drops in blood sugar (hypoglycemia) with the higher dose.

Researchers believe this higher dose could help more people achieve their health goals and reduce the worldwide burden of obesity. They also noted that more research is needed to fully understand the long-term benefits and risks.

5 Early Warning Signs of Lymphoma Doctors Say To Watch For

Updated Sep 15, 2025 | 03:34 PM IST

SummarySpreading awareness about lymphoma on World Lymphoma Awareness Day is important, as spotting the disease early and starting treatment in time can greatly improve recovery chances. A major challenge is that many people are unfamiliar with its warning signs, which often leads to late diagnosis.

Lymphoma is a form of blood cancer that starts in the lymphatic system, an essential part of the body’s immune defense. It develops when lymphocytes, a type of white blood cell, begin to grow and multiply in an abnormal way. The condition is broadly classified into two types, Hodgkin lymphoma and non-Hodgkin lymphoma, each with its own features and treatment methods, as per the American Oncology Institute. With cases becoming increasingly common, here are some of the early warning signs of lymphoma you should be aware of.

What Is World Lymphoma Awareness Day?

World Lymphoma Awareness Day is observed every year on September 15 as a global health initiative to educate people about lymphoma, one of the most common types of blood cancer. The day serves as a reminder to break the silence around the disease, raise awareness, and strengthen support for those living with it.

According to Netmeds, the theme for World Lymphoma Awareness Day 2025 is ‘Honest Talk.’ This year’s message highlights the need for open and transparent conversations between patients, caregivers, families, and healthcare professionals.

5 Early Warning Signs of Lymphoma

Lymphoma affects thousands of people around the world each year, yet many remain unaware of its early symptoms until the disease has advanced. Recognising these signs can make a crucial difference in seeking timely medical help. Experts highlight the following five warning signals to watch for:

1. Swollen Lymph Nodes

A painless lump in the neck, armpit, or groin that doesn’t go away is one of the most common signs. While infections can also cause swelling, those nodes are usually tender and tend to shrink within a week or two, according to Healthline.

2. Unexplained Weight Loss

The National Library of Medicine notes that losing 10% or more of your body weight within six months without trying is a frequent symptom of lymphoma and can sometimes point to a poorer prognosis. This weight loss happens because cancer cells consume the body’s energy.

3. Persistent Fatigue

Unlike normal tiredness, lymphoma-related fatigue does not improve with rest and may linger for weeks. It may stem from the cancer itself, over-activity of the immune system, or anemia if the bone marrow is affected. Many people mistake it for stress or poor sleep.

4. Itching or Skin Changes

Some patients experience intense itching without a visible rash, which is triggered by chemicals released in the body’s immune response. In rarer cases of cutaneous lymphoma, red or scaly patches may appear on the skin.

5. Night Sweats

Drenching night sweats that soak clothes or bedding are another important symptom. Unlike ordinary sweating, these episodes can occur even in cool environments, according to the American Oncology Institute.

Spotting these signs early gives you the chance to seek medical help before lymphoma advances, when treatment is most effective. If you notice any of these symptoms lasting longer than two weeks, make an appointment with your doctor. An early check-up will ensure you get the right evaluation and tests without any delay.
