All about H3N2 virus

                                                               

H3N2 influenza virus, also known as the Hong Kong flu, is a subtype of the influenza A virus that causes respiratory illness in humans. The H3N2 virus first emerged in 1968 and caused a pandemic that spread globally, resulting in an estimated one million deaths.

Like other influenza viruses, H3N2 can mutate rapidly, which makes it challenging for researchers to develop effective vaccines. The virus can also be transmitted from animals to humans, and from humans to animals, leading to outbreaks in both populations.

Symptoms of H3N2 infection are similar to those of other flu strains and can include fever, cough, sore throat, runny or stuffy nose, body aches, headaches, and fatigue. Most people recover from H3N2 flu within a week or two without requiring medical treatment. However, in some cases, complications such as pneumonia or bronchitis can develop, which may require hospitalization.

H3N2 is primarily spread through respiratory droplets when an infected person talks, coughs, or sneezes. The virus can also survive on surfaces for several hours, making it possible to contract the infection by touching a contaminated object and then touching one's mouth, nose, or eyes.

Prevention measures for H3N2 influenza include getting vaccinated, washing hands regularly with soap and water, covering the mouth and nose when coughing or sneezing, and avoiding close contact with sick people. Treatment for H3N2 flu typically involves antiviral medications to reduce symptoms and prevent complications.

H3N2 influenza virus is a highly contagious respiratory illness that can cause significant morbidity and mortality. While vaccines and antiviral medications can help prevent and treat the disease, it is essential to practice good hygiene and avoid close contact with sick individuals to reduce the risk of infection.
