If you are dealing with parents desperately wanting their offsprings free from sneezing and cough, advise them to buy a cat or a dog! According to the article (1) by Finnish specialists, published in the July issue of Pediatrics journal, keeping furry animals contributes to the lower rate of respiratory infections in the child’s first year of life. Better resistance to microbes might be explained by the enhanced maturation of the immune system, which is presumably provoked by the exposure to antigens carried by animals. Various studies have already tested this hypothesis, but the results were often opposing. This time European researchers try to convince us one more time that, as far as children are concerned, the more dirt the better.
