Frequent Fevers: Causes And What You Need to Know

Experiencing frequent fevers can be both alarming and confusing. While a fever often resolves on its own, recurring episodes may indicate underlying issues that require attention. Understanding the causes and symptoms of persistent fever is crucial for effective management.

A fever is typically defined as a body temperature exceeding 100.4°F (38°C). Adults may experience a low-grade fever, while a high-grade fever is characterized by a temperature of 103°F (39.4°C) or higher. Fevers usually subside within 1 to 3 days, but if they persist or recur for up to 14 days, they may signal a more serious condition.

Causes of recurring fevers

One common cause of recurring fevers is viral infections. Viruses often trigger sudden fevers that disappear once the infection resolves. Bacterial infections are another culprit; they can cause intermittent or persistent fevers that require medical treatment to address the underlying infection.

Vaccinations can also lead to temporary fevers, which are generally short-lived. However, if the fever persists or is unusually high, it's important to consult a healthcare professional to rule out other causes.

Symptoms of recurring fevers 

Symptoms accompanying a fever include chills, hot-cold skin, irritability, lethargy, and general discomfort. These signs can indicate how severe the fever might be and whether further investigation is needed.

Persistent or recurring fevers, even if mild, should be evaluated by a healthcare provider. They could be a sign of a more serious infection or an underlying health issue that requires professional diagnosis and treatment. Understanding these signs and seeking timely medical advice can help manage and mitigate the impact of frequent fevers effectively.

What are the common types of fever?

According to a Healthline report, adults typically have a fever if their body temperature increases to 100.4°F (38°C). This is called a low-grade fever. A high-grade fever happens when your body temperature is 103°F (39.4°C) or above. Most fevers usually go away by themselves after 1 to 3 days. A persistent or recurrent fever may last or keep coming back for up to 14 days. A fever that lasts longer than normal may be serious even if it is only a slight fever. This is because a recurrent fever might be a sign of a more serious infection or health condition.
