H3N2 Flu On The Rise In Delhi: Symptoms And Precautions You Must Know

H3N2 SYMPTOMS

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 <span>viral</span> 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.

<h2>What Is the H3N2 Virus?</h2>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:<ul><li>Sudden high fever (often above 38–39°C) with chills</li><li>Persistent cough and sore throat</li><li>Severe fatigue, weakness, and body aches</li><li>Headache and nasal congestion</li><li>In children: nausea, vomiting, or diarrhea</li></ul>Many patients report fever lasting more than 5–7 days, with cough persisting even after other symptoms subside.

<h3>Precautions Against H3N2 Virus</h3>Prevention is key, and National Institute of Health recommend the following measures:

<ul><li>Wash hands regularly with soap and water for at least 20 seconds</li><li>Wear masks in crowded or poorly ventilated areas</li><li>Cover your mouth and nose when coughing or sneezing; dispose of tissues immediately</li><li>Avoid close contact with sick individuals; isolate infected household members if possible</li><li>Keep living spaces well-ventilated</li><li>Maintain good nutrition, hydration, and adequate rest</li><li>Consider the seasonal influenza vaccine, which often protects against H3N2 strains—especially important for children, the elderly, and those with chronic illnesses</li></ul><h2>H3N2 in the United States</h2>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.

Recently <span>weight loss</span> 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 <span>Ozempic</span>, 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 <span>semaglutide</span> (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 &amp; 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. 

<h2>How Much Semaglutide Dosage Helped People Lose Weight? </h2>

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. 

<h2>Is It Safe To Take More Semaglutide? </h2>

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.

<span>Lymphoma</span> 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.

<h2>What Is <span rel="noindex">World Lymphoma Awareness Day</span>?</h2>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.

<h2>5 Early Warning Signs of Lymphoma</h2>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:

<h3>1. <span rel="noindex">Swollen Lymph</span> Nodes</h3>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.

<h3>2. Unexplained Weight Loss</h3>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.

<h3>3. Persistent Fatigue</h3>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.

<h3>4. Itching or Skin Changes</h3>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.

<h3>5. Night Sweats</h3>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.

Although as kids many of us enjoyed the perfect vision, it isn’t uncommon to find that you may need glasses as things start looking blurry. <span>Weak eyesight</span> can be caused due to a lot of reasons, whether it is strained usage of our eyesight like using improperly lit spaces to read, using electronics at night, or simply aging. 

The simple science behind wear eyesight is when the muscles that aid our vision get weak. So, if there was just a way to rejuvenate those muscles, we would be able to see properly, right? But it is not that simple. Doing so would require surgical options, many of which are not available easily. However, a new study may have made headway into creating an eyedrop that will do the job. 

A study presented on Sunday at the European Society of Cataract and Refractive Surgeons (ESCRS) suggests that eye drops could be a safe and effective treatment for presbyopia, a common age-related condition that causes long-sightedness and makes it difficult to focus on close-up objects. The study, conducted by experts in Argentina, explored a new type of eye drop that could offer a convenient alternative to wearing reading glasses. 

<h2>Can Eyedrops Fix Weak Eyesight? </h2>

The eye drops contain two main ingredients that work together to improve near vision. The first is pilocarpine, a drug that makes the pupil smaller and tightens the muscle that controls the shape of the eye's lens. This action helps the eye focus on nearby objects more easily. 

The second ingredient is diclofenac, which is a type of anti-inflammatory drug. It helps reduce any inflammation in the eye. 

In the study, 766 people used these drops twice a day, typically once in the morning and again about six hours later. They were split into three groups, each receiving a different strength of the pilocarpine component (1%, 2%, or 3%) while the amount of diclofenac stayed the same for everyone. 

<h2>How Effective Are <span rel="noindex">Eyedrops For Weak Eyesight</span>? </h2>

The study's findings were very encouraging, showing significant improvements in near vision for all participants, with the effects lasting for up to two years. 

For the group using the lowest concentration of pilocarpine (1%), almost all 148 people were able to read at least two additional lines on a standard eye chart. In the group with the 2% concentration, 69% of the 248 people could read three or more extra lines. The best results were seen in the 3% group, where a remarkable 84% of the 370 people could read three or more extra lines. 

On average, patients saw an improvement of more than three lines on the eye chart just one hour after using the drops. According to Dr. <span>Giovanna Benozzi</span>, a leading researcher, these drops offer a promising solution that is more convenient and has fewer risks than traditional options like reading glasses or surgery. 

<h2>Are There Side-Effects of Eyedrops For Weak Eyesight? </h2>

While the results are positive, some experts have expressed caution about potential side effects. The most common ones reported were temporary blurred vision, eye irritation, and headaches. 

However, experts warned that long-term use of pilocarpine could sometimes lead to side effects like reduced night vision. He also noted that using anti-inflammatory drops for a long time could pose risks to the cornea, the clear front part of the eye. He emphasized that more extensive and longer-term studies are needed to confirm the safety and effectiveness of the drops for widespread use.
