Signs and Symptoms

The elevation in thermoregulatory set-point means that the previous "normal body temperature" is considered hypothermic, and effector mechanisms kick in. The person who is developing the fever has a cold sensation, and an increase in heart rate, muscle tone and shivering in an attempt to counteract the perceived hypothermia, thereby reaching the new thermoregulatory set-point.

  • Influenza-like illness is defined as "fever (temperature of 100°F [37.8°C] or greater) and a cough and/or a sore throat in the absence of a known cause other than influenza."[1] Possible causes include respiratory syncytial virus, rhinovirus, adenovirus, parainfluenza viruses, coronaviruses, and metapneumovirus.[2]
  • Myalgias, when prominent, suggests Dengue fever. When myalgias localize to the calves, low back, or abdomen, consider leptospirosis.
  • Liver and renal failure when present, suggest leptospirosis ("Weil's disease")
  • Vertebral osteomyelitis or spondylitis suggests brucellosis
