What to do if You Have a Fever for More Than 3 Days

Usually, fever is a common sign of illness. It indicates your body is fighting infections. But is it the cause of concern?

Well, not always. But can a fever persist for more than three days be a cause for concern? 

Knowing the cause of prolonged fever is important, as it can leave you feeling drained, worried, and unsure of what steps to take. Don't panic. You're not alone in this. In this article, let's understand what a fever is, its causes, and what to do if it persists for more than a few days.

What is Fever?

Fever occurs when body temperature exceeds the normal range, around 98.6°F (37°C). It indicates the body is fighting off infections, as many bacteria and viruses can't survive at higher temperatures.

• Low-grade fever: 100.4°F to 102°F (38°C to 38.9°C)
• Moderate fever: 102°F to 104°F (38.9°C to 40°C)
• High fever: 104°F to 106°F (40°C to 41.1°C)

Normal body temperature varies, but anything above 100.4°F (38°C) is a fever. Normally, the fever is temporary, but if it lasts more than three days, it can indicate something more serious.
