It can affect people of all ages. Most infections remain mild and improve within about a week. However, severe cases can cause pneumonia, respiratory failure, hospitalisation and death, especially among high risk groups.<\/span><\/p>\n<h2><b>Why is H1N1 Virus in News?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Delhi has reported 1,344 H1N1 Virus (influenza) cases this season, compared with 229 during the corresponding period last year. This is nearly a six fold increase. The rise has again focused attention on seasonal Influenza, its transmission, symptoms and risk of severe disease.<\/span><\/p>\n<h2><b>H1N1 Virus<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">H1N1 Virus is an Influenza A subtype. The virus responsible for the 2009 pandemic is called A(H1N1)pdm09 and continues to circulate as a seasonal virus.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Full Form:<\/b><span style=\"font-weight: 400;\"> H1N1 refers to Hemagglutinin 1 and Neuraminidase 1. These names identify two surface proteins used to classify Influenza A virus subtypes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>H1N1 Disease:<\/b><span style=\"font-weight: 400;\"> H1N1 causes an acute respiratory infection commonly called Swine flu. Influenza has four types, A, B, C and D, while A and B cause seasonal epidemics in humans.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>2009 Pandemic:<\/b><span style=\"font-weight: 400;\"> The new A(H1N1) virus was first reported in North America in April 2009. WHO declared a pandemic in June 2009 after infections were confirmed in 74 countries and territories.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Origin: <\/b><span style=\"font-weight: 400;\">Genetic analysis showed that the 2009 virus originated from animal Influenza viruses. It was different from human seasonal H1N1 viruses circulating since 1977.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>First Case in India:<\/b><span style=\"font-weight: 400;\"> India reported its first confirmed H1N1 case in May 2009. The virus has since caused several outbreaks, with significant cases reported in 2021, 2022 and 2023.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Transmission: <\/b><span style=\"font-weight: 400;\">Swine Flu mainly spreads through respiratory droplets released during coughing and sneezing. Infection can also occur after touching contaminated surfaces and then touching the mouth or nose.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Incubation: <\/b><span style=\"font-weight: 400;\">Symptoms generally appear about two days after infection. The incubation period can range from one to four days, allowing transmission before symptoms become clearly noticeable.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Diagnosis: <\/b><span style=\"font-weight: 400;\">Most cases are identified clinically. Laboratory testing of respiratory samples can confirm infection. RT PCR can detect Influenza specific RNA and generally has better sensitivity than rapid diagnostic tests.<\/span><\/li>\n<\/ul>\n<p><strong>Also Read: <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/difference-between-pandemic-and-epidemic\/\" target=\"_blank\">Difference Between Pandemic and Epidemic<\/a><\/strong><\/p>\n<h2><b>H1N1 Virus Symptoms<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">H1N1 Virus symptoms usually begin suddenly and resemble those of ordinary seasonal flu, with fever, cough, body pain and marked tiredness being common features.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Common Symptoms: <\/b><span style=\"font-weight: 400;\">Fever, dry cough, sore throat, headache, muscle and joint pain, runny nose, chills and severe tiredness are common symptoms of Swine Flu infection.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Other Symptoms: <\/b><span style=\"font-weight: 400;\">Some infected people may experience vomiting or diarrhoea. Symptoms generally improve within about a week, although cough and weakness can continue for two weeks or longer.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Severe Illness: <\/b><span style=\"font-weight: 400;\">H1N1 can sometimes cause serious complications. Pneumonia, respiratory failure and sepsis have been reported in severe infections requiring medical attention.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>High Risk Groups:<\/b><span style=\"font-weight: 400;\"> Pregnant women, children below five years, adults aged 65 years and above and people with chronic diseases face a higher risk of severe Influenza.<\/span><\/li>\n<\/ul>\n<h2><b>H1N1 Virus Prevention and Treatment<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Prevention of the H1N1 Virus focuses on vaccination, hygiene and limiting exposure, while treatment depends on disease severity and the person&#8217;s risk of complications.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Vaccination: <\/b><span style=\"font-weight: 400;\">WHO considers vaccination the best protection against seasonal Influenza. Annual vaccination is recommended because immunity declines over time and circulating viruses continually change.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Hygiene: <\/b><span style=\"font-weight: 400;\">Regular handwashing, proper disposal of tissues, covering the mouth and nose while coughing or sneezing and avoiding unnecessary contact with infected people can reduce the spread of Swine Flu.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Isolation: <\/b><span style=\"font-weight: 400;\">This helps limit transmission, particularly during the infectious period.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Antiviral Treatment: <\/b><span style=\"font-weight: 400;\">WHO recommends antiviral medicines as soon as possible for high risk patients and people with severe Influenza. Treatment within 48 hours may reduce severe complications and deaths.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Public Health Measures:<\/b><span style=\"font-weight: 400;\"> Effective control requires adequate vaccination, diagnostic facilities, disease surveillance and awareness, particularly for pregnant women, young children, older adults and people with chronic illnesses.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>H1N1 Virus is an Influenza A subtype that causes Swine Flu.
