Is a temperature of 99.1 a fever?
When someone has a fever, the body raises the normal body temperature (as measured orally) above 37.5°C (99.5°F). A rectal temperature above 38°C (100.4°F) or an underarm temperature above 37.2°C (99°F) is also considered a fever.
The doctors consider the rise in body temperature as fever if it crosses the mark of 99.4°F when taken orally and 100.4°F when taken rectally.
- The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
- Can allergies cause a fever? Allergies can cause symptoms that are very similar to a cold or flu, such as a runny nose, sore throat, or sneezing. However, allergies do not cause a fever.
- A normal temperature is about 98.6°F (37°C) when taken orally (in your child's mouth) and 99.6°F (37.5°C) when taken rectally (in your child's bottom). Many doctors define a fever as an oral temperature above 99.5°F (37.5°C) or a rectal temperature above 100.4°F (38°C).
In general, a baby has a fever when their body temperature exceeds 100.4°F, or 38°C. A child has a fever when their temperature exceeds 99.5°F, or 37.5°C. An adult has a fever when their temperature exceeds 99 to 99.5°F, or 37.2 to 37.5°C.
- A rectal thermometer may be used for measuring body temperature in infants. In general, a baby has a fever when their body temperature exceeds 100.4°F, or 38°C. A child has a fever when their temperature exceeds 99.5°F, or 37.5°C. An adult has a fever when their temperature exceeds 99 to 99.5°F, or 37.2 to 37.5°C.
- A low-grade fever is often classified as an oral temperature that is above 98.6° F (37° C) but lower than 100.4° F (38° C) for a period of 24 hours. 1. A fever of 103° or higher is more concerning in adults. Fevers, though uncomfortable, play a key role in helping your body fight off many infections. 2.
- A 99.5 temperature is normal for anyone. The average temperature is 98.6 so this is just a one degree variation that doesn't mean you have a fever. Temperatures also vary by time of day (lower in the morning; higher in the late afternoon); by as much as two degrees.
