People are able to notice the first signs of illness

British scientists have gathered evidence that people are able to recognize signs of disease and act on the situation. If you have a disease of your own body, strive to take medications that improve health. And if you find signs of disease in other people - avoid contact with the spread of the infection.

People are able to notice the first signs of illness

English scientists did not discover America - cough, runny nose and sneezing, a priori defined by people as signs of a disease. However, it is too early to draw hasty conclusions, because such symptoms are not suitable for infectious diseases, but allergic reactions, which are present in one third of the world's inhabitants.

As for the conclusion of scientists, the conclusion allowed to draw a study on two groups of people. Experimenters injected vitamins into one group and harmless protein antigens causing temporary fever in the other group. After that, the experimental people were photographed and the cards were shown to other volunteers who established signs of the disease.

Interestingly, according to photographs, respondents indicated sick people with a probability of 60%, but 70% of volunteers agreed to guarantee the absence of diseases. However, when patients of both groups were seen, the success of the correct determination of infected patients increased to 95%. It turns out that red eyes, pallor of a face, a lost look in a photo are difficult to determine.
