Yes, there still exists fever phobia in our society, which brings hoards of worried parents into the ED with their febrile kids. For most of these kids it’s relatively straight forward: Most kids with fever have clinical evidence of an identifiable source of infection – a viral respiratory infection, acute otitis media, gastro, or a viral exanthem. However, about 20% have Fever Without a Source despite your thorough history and physical exam.
Pandemic sparked demand for thermal imaging devices but some manufacturers warn against products that can’t properly screen for fevers.
Fever is a more flexible concept than previously thought, as new crowdsourced data show.
The fever phobia that parents experience is ancient and useful.
A team at Boston Children’s Hospital is trying to create a new way of diagnosing fevers while questioning one of the most basic medical tenets. Normal human body temperature may not be 98.6 degrees Fahrenheit, they say, and a fever may not be 100.4 degrees or higher.
What’s a “normal” human body temperature? It depends.
These devices are fun to play around with, but they’re also really useful—if you know the science behind them.
No-touch thermometers were originally used in industry, from manufacturing to firefighting, and they're a trusted resource, says physiologist Dr. Benjamin Levine at the University of Texas Southwestern Medical Center.
Everyone knows the number 98.6. When you were a kid, it was that golden degree that you had to surpass in order to officially have a fever—and a chance of missing school. But although we all think of that number as the average human temperature, it’s not actually as accurate as mainstream culture treats it. Unsurprisingly, human bodies are all different, which means that 98.6°F does not equate to the perfect temperature for any one person.
A smart thermometer company says its data could help track COVID-19. There are reasons to be skeptical.
The presence of a fever is usually related to stimulation of the body's immune response. Fever can support the immune system's attempt to gain advantage over infectious agents, such as viruses and bacteria, and it makes the body less favorable as a host for replicating viruses and bacteria, which are temperature sensitive.
Fevers can be caused by both bacteria and viruses — so the adage “Feed a cold, starve a fever” is an oversimplification. But knowing whether to feed patients based on the infection they have could be useful not just for chicken soup remedies but also for more serious infections like sepsis, which can be caused by both types of pathogens.
The answer is simmering in a bowl of chicken soup.
Does a fever always mean you have an infection?
