NewCDC Study Finds Strong Vaccine Effectiveness Against Severe Flu Outcomes. December 5, 2023 — A new CDC-coauthored study published in Clinical Infectious Diseases found that flu vaccination last season substantially reduced the risk of serious flu outcomes. The study looked at how well flu vaccination protected against flu Keyfacts. Humans can be infected with avian, swine and other influenza viruses. Direct contact with infected animals (through handling, culling, slaughtering or processing) or indirect contact (through environments contaminated with bodily fluids from infected animals) represent a risk for human infection. Exposure to animal influenza Whatis H3N2 : दिल्ली-एनसीआर में भी इस घातक फ्लू और लंबे वक्त तक सीने में जकड़न या Clinicaldifferences between H3N2 and H1N1 influenza 2012 and lower respiratory tract infection found using a statistical classification approach Dimitris Petridis , 1 Paul Zarogoulidis , 2, 3 Anastasios Kallianos , 4 Ioannis Kioumis , 2 Georgia Trakada , 5 Dionysios Spyratos , 2 Antonis Papaiwannou , 2 Konstantinos Porpodis , 2 Haidong Whatis H3N2 Canine Influenza Virus? H3N2 canine influenza virus (H3N2 CIV) is a very contagious influenza virus that infects dogs. This virus recently emerged in the US in 2015. It has already infected thousands of dogs in more than 30 states. H3N2 CIV has also infected cats in shelters, but this may not be a common occurrence. There is no H3N1and H3N2 thus have similar hemagglutinin proteins, but distinct neuraminidases. And it is one of these random mutations that is responsible for the decreased efficacy of this year’s flu vaccine. You see, when the vaccine was grown in chicken eggs, the HA gene mutated. Casesof influenza-A subtype H3N2 are on the rise, with a few deaths reported across India. The government says it’s keeping a close watch on the situation and has issued advisories. AH3N2) virus predominated recent influenza seasons, which has resulted in the rigorous investigation of haemagglutinin, but whether neuraminidase (NA) has undergone antigenic change and Forvaccination of healthy dogs 8 weeks of age or older against canine influenza (H3N2 and H3N8) virus infection. Indications. Effective for the vaccination of healthy dogs 8 weeks of age or older against canine influenza (H3N2 and H3N8) virus infection. H3N2influenza, also known as the "Hong Kong flu," is a type of influenza virus that can cause respiratory illness in humans. It is a subtype of the Influenza A virus and has been responsible for several influenza outbreaks in the past. There has been a sudden surge in the number of H3N2 influenza cases in New Delhi, where people are H3N2influenza wave hits country: Symptoms, precautions, dos and don'ts. TIMESOFINDIA.COM / Updated: Mar 6, 2023, 12:36 IST. Hospitals across the country have been reporting thousands of cases of Influenza A subtype H3N2 over the past few months, which causes fever for 3-5 days and a persistent cough that can last up to three weeks. H3N2infections can range in intensity from mild to severe, depending on variables such as age, general health, and the presence of other illnesses,” says Dr TS. What makes H3N2 more deadly than other influenza strains? Since H3N2 tends to mutate more quickly, it is more difficult for flu vaccines to keep up with its mutations. H3N2influenza is also known as the “Hong Kong flu”. Patients are taking more time to recover and coming on the heels of the Covid-19 pandemic, this virus has led to widespread concerns. Whatis H3N2? The influenza A virus is known to cause seasonal flu disease in humans. These are divided into subtypes based on two proteins found on the surface H3N2influenza, also known as the “Hong Kong flu,” is a type of influenza virus that can cause respiratory illness in humans. It is a subtype of the Influenza A virus and has been responsible for several influenza outbreaks in the past. Spread: H3N2 influenza is highly contagious and can spread from person to person through droplets .
