If your fever lasts more than three days, it’s a sign that something more serious could be going on. While a short-term fever might be due to a common viral infection, a persistent fever could point to conditions like dengue, typhoid, malaria, or even a bacterial infection that needs antibiotics. Relying on self-medication or waiting it out can delay proper treatment and lead to complications. Fever is your body’s way of signaling that it's fighting an infection, but without the right tests and diagnosis, it's impossible to know what's causing it. If you or a loved one has a fever that continues beyond 72 hours, along with symptoms like chills, body aches, weakness, or rash, don’t wait—get tested and consult a doctor immediately. Early diagnosis ensures quicker recovery and avoids serious health risks.
