Sick poultry, pet birds, pigs, cows and dromedary camels cause diseases in humans

We remember still a single farm with chickens and pigs on the farm and cows in the pasture. Increasingly we see grain silos appear with large livestock farming, whose pigs, chickens or cows never outside come. Diseases, which can be transmitted from  animals to humans, are the result.
Prevention is essential for all of us in order to make our environment healthier and reduce the increase of chronic diseases.
Lifestyle changes, such as the purification of drinking water, sewage treatment and the introduction of the refrigerator, brought us more health benefits than medicines produced by the pharmaceutical industry. It is of great importance that the air we breathe indoors in private homes, public buildings and factory farms, is free from contaminants in order to prevent the spread of flu, which can affect all.
