Why testing for flu early can keep you safe this season

Influenza, caused by viruses like A/B/H1N1, is a contagious respiratory illness with symptoms like fever, fatigue, and cough. Early diagnosis via molecular testing (RT-PCR) is key to distinguishing it from COVID-19 or RSV. Annual flu vaccination, hygiene, and prompt treatment can prevent severe cases, especially in children and the elderly, during peak flu season.
