Can a cold cause a low-grade fever?

Patients with the common cold may experience low-grade fever. Some patients with more severe colds may develop systemic clinical symptoms, such as low-grade fever, body aches, fatigue, and general malaise. The cause of low fever may be due to weakened immune function or a mild inflammatory response in the body. It is recommended to promptly take antipyretic medications or use physical cooling methods to relieve symptoms.

1. Reduced Immune Function

This condition is commonly seen in individuals who are particularly weak, such as bedridden patients or elderly people. Due to their weakened immune systems, their resistance against viral or bacterial invasion is reduced, leading to a milder inflammatory response. Low-grade fever caused by a cold can be appropriately treated with antibiotics or antiviral drugs to stabilize the condition. Symptoms may also be managed using traditional Chinese patent medicines, such as cold capsules, Lianhua Qingwen capsules, or Lanqin oral liquid.

2. Mild Inflammatory Response

When external agents such as viruses or bacteria invade the body, they may produce only minor effects—not entirely harmless, but limited. The body's defensive reaction to these invaders can result in a mild inflammatory response, causing low-grade fever. This situation usually indicates that the body's immunity is relatively intact. Treatment may include antibiotics or antiviral medications, although specific treatment might not always be necessary. Maintaining warmth, increasing fluid intake, and consuming more fresh fruits and vegetables can support the body’s natural recovery process.

For low-grade fever caused by the common cold, timely measures should be taken based on the individual patient's condition to prevent worsening of symptoms.
