Infection causes localized inflammation and blood vessel dilation around the infected area to deliver white blood cells and immune cells, which increases blood flow and heart rate as part of the immune response.

Evidence Quote
“what happens when you're an infection is that you normally get localized inflammation around where the infection is and what happens then is that your body will will dilate the blood vessels around that area and also make the blood vessels more permeable so this will then increase blood flow into that area it'll also increase your heart rate”
