Rising Flu in Delhi: Symptoms, Types & How to Protect Yourself | MaxAtHome

1. Rising Flu Cases in Delhi: Understanding H3N2, Influenza B & H1N1 – Symptoms, Prevention & Treatment

2. Why Are Flu Cases Rising in Delhi? Several factors are contributing to the current surge in flu cases:Weather fluctuations – sudden temperature changes weaken the body’s natural defence system. Air pollution – high levels of pollutants irritate the respiratory tract, making people more susceptible to infections. Viral spread in crowded settings – schools, offices, and public transport provide easy transmission routes.Beyond these environmental and lifestyle factors, the specific influenza strains circulating in Delhi are also shaping the outbreak. Recent reports highlight three dominant strains: H3N2 influenza virus Influenza B virus  H1N1 (Swine Flu)  What is Seasonal Flu (Influenza)? Seasonal flu, often referred to as influenza, is a contagious respiratory illness caused by influenza viruses. Unlike mild viral infections, the flu can lead to moderate to severe symptoms and, in some cases, complications requiring medical care. The illness spreads easily through coughing, sneezing, or contact with contaminated surfaces, making it a recurring public health concern every year.

3. H3N2 Influenza Virus Common Types of Flu in Delhi Right Now The current flu season in Delhi is primarily driven by three influenza strains. Understanding their symptoms, risks, and transmission patterns is crucial for early detection, timely care, and reducing the spread of illness across the city. H3N2 is a subtype of the Influenza A virus and is known for causing severe seasonal flu outbreaks. Infected individuals often experience high fever, severe body aches, fatigue, sore throat, and persistent cough. Older adults and people with chronic health conditions are particularly vulnerable to complications such as pneumonia or hospitalisation. The virus spreads rapidly because it is highly contagious, easily transmitted in crowded environments including schools, offices, and public transport. Its fast transmission makes H3N2 a major contributor to the ongoing Delhi flu outbreak, emphasising the importance of preventive measures and timely medical attention. Influenza B Virus Influenza B differs from Influenza A strains like H3N2 in that it generally causes milder illness, but it can still lead to serious symptoms, particularly in children and young adults. Common signs include fever, cough, sore throat, fatigue, and mild body aches. Children, teenagers, and younger adults are most frequently affected, while older adults may experience less severe symptoms. Awareness of influenza B symptoms helps families and caregivers detect the illness early and seek appropriate care, reducing the risk of wider transmission.

4. Symptoms of Flu to Watch Out For While flu symptoms can vary depending on the strain and the individual’s health, common signs to watch out for include: Fever and chills – Sudden onset of high fever is a hallmark of influenza, often accompanied by shivering and sweating. • Sore throat and cough – A persistent sore throat and dry or productive cough are common, and may last several days. • Runny or stuffy nose – Nasal congestion, sneezing, and a runny nose are frequently observed, particularly in children. • Runny or stuffy nose – Nasal congestion, sneezing, and a runny nose are frequently observed, particularly in children. • Muscle and body aches – Flu often causes widespread body aches, especially in the back, legs, and joints. • Fatigue and weakness – A feeling of extreme tiredness and low energy can persist even after other symptoms subside. H1N1 (Swine Flu) H1N1, commonly known as Swine Flu, presents with sudden fever, cough, sore throat, body aches, and fatigue. In severe cases, it can cause pneumonia, breathing difficulties, or hospitalisation, especially among high-risk groups such as the elderly, pregnant women, and those with chronic illnesses. H1N1 has caused multiple outbreaks in Delhi over the past decade, and current surveillance indicates it continues to circulate. Timely testing for H1N1 influenza and adherence to preventive measures remain critical for controlling its spread.
