👉 The Bug Flu, also known as the H5N1 avian influenza pandemic, is a highly contagious and often lethal respiratory illness caused by a type of influenza virus. Unlike typical flu viruses, Bug Flu can spread rapidly through human-to-human transmission, leading to severe symptoms such as fever, cough, and difficulty breathing. The virus is particularly dangerous because it can mutate quickly, making it difficult to contain and treat with existing vaccines or antiviral medications. The term "bug" in Bug Flu is a colloquial reference to the rapid and insidious nature of its spread, causing widespread panic and disrupting global health systems.
