Influenza h3n2 symptoms

H3N2 flu claims two lives: Health Ministry “India every year witnesses two peaks of seasonal influenza – one from January to March and other in the post-monsoon season. The cases arising from seasonal influenza are expected to decline from March end,” the Ministry said. What is 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 of the virus: hemagglutinin (H) and neuraminidase (N). There are 18 H-subtypes and 11 N-subtypes. More than 130 influenza A subtype combinations have been identified in nature so far, but virus reassortment, a process by which influenza viruses swap genetic information, makes many more subtypes possible, the U.S. Centres for Disease Control and Prevention said. The H3N2 subtype appears to cause more hospitalisations than other influenza subtypes, India’s Ministry of Health and Welfare noted. About half of all inpatient severe acute respiratory infections (SARI) and outpatient illnesses displaying influenza-like symptoms seen in surveillance data collected between December 15, 2022, and March 10, 2023, were found to have been H3N2 infections. Out of the SARI patients infected with H3N2, 10% needed oxygen, and 7% needed ICU support. Symptoms Infection by the H3N2 subtype of influenza A virus presents with classic flu symptoms that are also similar to COVID-19 symptoms – fever, cough, body ache, breathlessness, wheezing and pneumonia.

H3N2 TreatmentDoctors have prescribed lots of fluids and proper rest. The one thing that is important to remember here is to avoid antibiotics or pain killers without prescription. Doctors have strictly advised against popping the readily available antibiotics off the counter. It is important to get yourself tested and only follow the course of treatment suggested by the medical professional.

READ: FLU SEASON STARTED IN LAST WEEK OF APRIL The 2023 flu season started in Epidemiologic Week 17 (on 27 April) when the flu detection rate exceeded the The increase in cases was noted in all six provinces where influenza-like illness (ILI) and pneumonia are surveilled. KwaZulu-Natal, Mpumalanga, Gauteng, Western Cape, Eastern Cape, and North West.

Influenza A(H3N2), A(H1N1)pdm09, and influenza B commonly circulate in South Africa seasonally. The NICD said Influenza A(H1N1)pdm09 is sometimes incorrectly referred to as “swine flu” – it has been circulating since its emergence in 2009. “The term ‘swine flu’ should not be used as it causes unnecessary panic. The clinical course of infection and management of this strain is similar to other influenza strains,” said the Institute. SYMPTOMS As previously reported, common flu symptoms include fever, muscle pains, body aches, dry cough, sore throat, runny nose, fatigue, and headache. These symptoms usually present between one to four days after infection and last for two to seven days. In most cases, symptoms re...
