What does it mean when your temperature is 38.5?

A temperature of 38.5 degrees Celsius (101.3 degrees Fahrenheit) is considered a low-grade fever.

Possible causes

A low-grade fever can be caused by a variety of factors, including:

- Viral infection, such as the common cold or flu

- Bacterial infection, such as a urinary tract infection or strep throat

- Overheating, such as from strenuous exercise or hot weather

- Certain medications, such as antibiotics or antihistamines

- Immunization

- Teething in children

When to see a doctor

In most cases, a low-grade fever is not a cause for concern and will resolve on its own within a few days. However, it is important to see a doctor if:

- The fever is accompanied by other symptoms, such as a headache, stiff neck, rash, or shortness of breath

- The fever persists for more than 3 days

- You have a weakened immune system

- You are pregnant

Treatment

There are a few things you can do to treat a low-grade fever at home, including:

- Resting

- Drinking plenty of fluids

- Taking over-the-counter pain relievers, such as acetaminophen or ibuprofen

Prevention

There are no specific ways to prevent a low-grade fever, but you can reduce your risk of developing a fever by:

- Washing your hands frequently

- Avoiding contact with people who are sick

- Getting vaccinated against common infections, such as the flu

- Dressing appropriately for the weather
