What is the pulse rate during fever?

The mean heart rate during the febrile period was 84.0 beats per minute. After recovery, it was 66.5 beats per minute. When the temperature rose by 1 degree C, the heart rate increased on the average by 8.5 beats per minute. During the febrile period, the heart rate remained high, even during sleep.

Does your pulse rate go up when you're sick?

There is some evidence that an increase in heart rate might be one of the first signs that someone is getting sick. Studies of Ebola infections in primates, for example, found that changes in heart rate happened about 48 hours before the start of a fever.
