Average normal body temperatures in older adults are slightly lower than in younger adults. So when an older adult is sick, their fever temperatures may also be lower.
According to the CDC, the following temperatures in older adults may be signs of an infection, such as COVID-19 or the flu:
A single temperature reading higher than 100°F (37.8°C)
Multiple temperature readings above 99°F (37.2°C)
A rise in temperature greater than 2°F (1.1°C) above the person’s normal body temperature
If you are concerned that you may have a fever or other signs of flu, talk with a health care provider to find out what steps you can take to feel better.
