In recent centuries, thanks to advancements in chemistry and laboratory techniques and equipment, feeding and hygiene improvements, the rate of mortality of various diseases has decreased considerably, thus increasing the life expectancy.
Many important discoveries in medicine have occurred by chance like that of Gregor Mendel (1822-1884) who published in 1865 his books on plants, from which they formed and spread to the laws of Mendel, which then form the basis classical genetics, this has enabled the discovery of DNA structure occurred in 1953. Another emblematic case was that of Alexander Fleming in 1928 saw, somewhat amazed, the disappearance of some colonies of Staphylococcus from a tube through the action of a small mold, testing, thus, the concept of antagonistic bacteria and antibiotic activity essential to eradicate infectious diseases.
Medicine, with its testing is often contrasts with the religion of the people and the religion they believe, and with both the ethical and moral principles of the individual. In 1930 several controversial medical practices were introduced including the ’shock and lobotomy, and in recent years, abortion and cloning are the subject of controversy.
Often, especially in modern times, diseases are discovered first as a series of events of symptoms that involve multiple organs and then called syndromes, and then only after a time tested and studied, be referred to as real diseases. This happened in cases such as’ AIDS (which stands for Acquired Immune Deficiency Syndrome) with which you define the syndrome in which there is a set of events due to depletion of T lymphocytes, [11] and SARS (acronym for Severe acute respiratory syndrome), an atypical form of pneumonia caused by a specific virus, which appeared for the first time in November 2002 in Guangdong Province (Canton) in China, [12] and led to 813 deaths in the world and then almost disappear. “
