Humans Can Spot Signs of Illness at a Glance

Coughing, sneezing and clutching the stomach might be obvious signs of sickness, but humans can also spot if someone is healthy simply from a glance at their face, new research suggests. Scientists have found that signs of a person being acutely unwell -- such as pale lips, a downward turn of the mouth and droopy eyelids -- are visible just hours after an infection begins. While previous work has shown that besides overt symptoms -- such as sniffing -- changes in skin colour can serve as a guide to health, experts say the latest study highlights the ways in which humans might use a host of early signals to avoid contracting infection from others.


Dr. Rachel McMullan of the Open University said that it would be helpful to look at whether the results held for a wide range of ethnic groups and for different diseases, but added the results suggested ill individuals could be spotted soon after infection.

"Being able to quickly identify and avoid potentially sick, contagious individuals will certainly be an evolutionary advantage and this study is a good starting point for further research into the how we detect early signs of infection," she said.


I can believe this. We find signs of health attractive and signs of illness unattractive.

It is easy to spot a mentally ill person. Just look for the "(R)" after their name.

Some (all?) humans also have a built in plague detection system.

If we see a certain amount of sores on the fac we immediately get upset no matter the distance.
