Scientists have shown the ability of people to notice the signs of the disease on the face, reports Rus.Media.

So, scientists have proven that symptoms of the disease people are able to notice after a couple of hours – to avoid contact with a carrier of the infection.

Sneezing, coughing, runny nose – some symptoms of the disease, we learn easy, trying to avoid unnecessary contact with a carrier of the infection. However, we discern and much more subtle details that show the disease, and they occur in the first hours of the acute phase.

Scientists describe double blind experiments carried out with 16 healthy volunteers. They were divided into two groups, one of which received placebo and the other portion of the protein antigens of E. coli are harmless, but they cause temporary symptoms of fever. Two hours after injection being photographed.

The pictures showed 62 other volunteers, who were asked five seconds to assess whether a person is healthy in the portrait. Disease participants had noticed only slightly better than random (52% success), but healthy people was determined successfully in 70% of cases.

Another group of 60 images were shown, asking you to assess the condition and fatigue depicted in the portraits of people in different settings. Among other things, the participants have identified characteristics such as swollen face, pale lips, red eyes, etc. the key figures were pale complexion and muddy eyes.

It is noted that such studies confirm the hypothesis of the existence of behavioral mechanisms that enable people to avoid infection.
