H2n3

Jump to: • • • • An outbreak of H3N2 flu in India has left at least two people dead, according to Health experts in India are That said, Sure, with everything we’ve been through over the past three years, it’s understandable to feel a little nervous when you hear about an outbreak. So, do you need to worry about H3N2 in the U.S.? Here’s the deal. What is H3N2? In general, H3N2 is a strain of the flu that you want to avoid, if possible. But experts point out that the U.S. just faced a flu season with H3N2. H3N2 flu viruses began circulating in people in 1968, according to “When you have seasons that are dominated by H3N2, you tend to see more flu-related deaths,” Dr. Adalja says. “H3N2 is a strain of seasonal flu—it has been the dominant strain in this year’s influenza season, including in the U.S.,” Dr. Adalja says. “India just appears to be having a later peak than in the U.S.—H3N2 already came and went in the U.S. flu season.” Should you be worried about H3N2? Dr. Adalja says it’s unlikely we’ll see H3N2 again this season, despite how rapidly it’s spreading in India. “People have immunity because of exposure” from this season, Dr. Adalja points out. With flu season coming to an end in the U.S., it’s also unlikely that H3N2 would double back, he says. Consider this, too, per Dr. Adalja: H3N2 was Given that H3N2—which is a form of influenza A—was the dominant strain of the flu in the U.S. this season, there is a chance that we could see a “little bump” in flu cases caused ...

Two deaths have been registered in India due to the H3N2 influenza, as per a Moneycontrol report, which quoted government sources as saying that Karnataka had seen one death and Haryana the second. Read more on this here Karnataka Health Minister Dr. K. Sudhakar had said on Monday that 26 persons have tested positive for the H3N2 variant in the state, and among these two cases are reported from Bengaluru. He added that children below the age of 15 years face more danger from the H3N2 variant and that the variant also infects persons above the age of 60 years. Addressing a press conference at the Vidhana Soudha after holding a high-level meeting over the rising Covid cases and H3N2 variant, Sudhakar advised that pregnant women also need to be careful. Sudhakar also said that a total of 60 cases of Adenovirus, which causes acute respiratory infections (ARI), were found in Karnataka. “For six months, the staff of the Health department have not been wearing masks. Right from this day, the staff who work in hospitals and health care centres must wear masks," he said. The country has seen an unexpected increase in Covid and H3N2 cases, which has experts concerned. Despite the fact that reported cases remain quite low, India has seen a 63% increase in cases over the last week. Dr Randeep Guleria, chairman of the Institute of Internal Medicine, Respiratory and Sleep Medicine, and Director of Medical Education, told ANI that the H3N2 virus mutates every year during this time and sp...

While people were slowly going ‘off-masks’, thinking Covid is almost over, they are now witnessing a new virus in the block – Influenza A-H3N2 – whose symptoms seem somewhat similar to corona virus. According to the World Health Organization (WHO), A-H3N2 is a subtype of influenza A viruses, that circulate and cause seasonal epidemics. Dr Sushila Kataria, Senior Director, Internal Medicine, Medanta, Gurugram says, "The symptoms for A-H3N2 include headache, fever, muscle pain, cough, sneezing, cold, body chills and fatigue. In the last one month, there has been an increase in the number of flu cases. This is usually the case in spring season. This time, the cases are the same, but the fever severity is a bit more and the cough is more intense. The cough is severe because of swelling on vocal cords and laryngitis (an inflammation of the voice box from overuse, irritation or infection).” Further, the WHO says that the effects of seasonal influenza epidemics in developing countries are not fully known, but research estimates that 99 per cent of deaths in children under five years of age with influenza-related lower respiratory tract infections are found in developing countries. All age groups can be affected due to this virus, but pregnant women, children under 59 months of age, elderly, and people with chronic diseases are likely to get more infected due to this virus. “There definitely has been an increase in cases. All age groups are getting influenza, including children. I...

You may be curious how these two pandemics compare with each other. Keep reading as we break down their similarities and differences below. 2009 H1N1 Influenza COVID-19 Year started – year ended 2009–2010 2020–present Worldwide deaths about 284,000 in the first 12 months about 2,000,000 in the first 12 months Virus 2009 H1N1 influenza virus SARS-CoV-2 coronavirus Transmission respiratory droplets and aerosols, contact with contaminated surfaces, asymptomatic spread respiratory droplets and aerosols, contact with contaminated surfaces, asymptomatic spread Contagiousness less contagious than COVID-19, contagious from 1 day before symptoms begin until 5 to 7 days after becoming sick more contagious than 2009 H1N1 influenza, contagious from 2 days before symptoms begin until 10 days after testing positive Symptoms fever and chills, fatigue, cough, body aches and pains, headache, sore throat, runny or stuffy nose, digestive symptoms like diarrhea and vomiting similar symptoms to 2009 H1N1 influenza, but also includes loss of smell and taste Symptom onset sudden after 1 to 4 days gradual after 2 to 14 days Age group most impacted people younger than 30 adults over age 30 Illness severity 94–98 percent mild 80 percent mild, 20 percent severe or critical Risk factors being 65 years or older, being...

Partners Facts about Flu - Ever wondered what flu classifications mean? Read on. The pandemic influenza strain, or swine flu, that spread globally in 2009 was referred to as H1N1 and the There are three major types of influenza that infect humans, known as influenza A, B and C. Influenza A and B can both cause serious infections, and are the cause of what we call the flu. Influenza C viruses differ from influenza A and B, and only cause a mild infection, so they don’t appear in vaccines. A pandemic influenza strain is one that humans have not been previously exposed to, so people do not have immunity to it. It also spreads rapidly in the community. When it has been around for a while and there’s widespread immunity to it, the virus will cause less serious illness, becoming one of the annual seasonal strains. But these seasonal strains continue to change all the time, never going back to the original strain. Hs and Ns Influenza A and B viruses have two types of spikes that cover their surface – the haemagglutinin (H) and the neuraminidase (N). Viruses attach by their haemagglutinin onto receptors on the surface of cells in order to...
