Infectious diseases

For centuries, infectious diseases have been, and remain to this day the most dangerous diseases affect the human body.And all of the fact that they are able to engage in the process a very large number of people in a short period of time.

Throughout most of human existence were the scourge of infectious diseases as cholera, smallpox, plague and yellow fever.They carried away the life of millions of people around the globe.For example, an epidemic of plague that enveloped London in 1665 led to the fact that the population of the city decreased by about ten percent.And infectious diseases such as tuberculosis and measles - caused by the deaths of entire tribes who lived on the islands of the Pacific Ocean after their first contact with European colonists.In the last century, and the generations of pregnancy, due to the development of postpartum sepsis represents a very great danger to the mother.And only thanks to the discovery of immunization Edward Jenner, Louis Pasteur

sterilization and Alexander Fleming receiving antibiotics - an opportunity to control many infectious diseases.

However, despite the power of modern medicine in the world today is completely eliminated only one infectious disease - smallpox.For all other infectious agents srazhenie still ongoing.Thanks to immunization programs, which are held around the world, the destruction of infectious diseases such as measles, whooping cough, diphtheria, polio and tetanus reached to date by more than ninety percent.

truly impressive results have been achieved thanks to the joint efforts of many countries doctors.So for example across the world, the number of deaths from measles between 1983 and 1992 declined from 2.5 to 1.1 million cases, and died in the same period of polio from 360 to 140 tysyach.Po all forecasts expected that in most countries polioIt will be defeated by 1995, but due to a significant rise in price of immunization, date of the complete destruction of the infection in Asia had to move on until an indefinite period.Such an infectious disease like malaria still claims the lives of one to two million people every year.

From - the high emigration of people from the so-called countries of the "third world" in recent years has again sharply increased the number of persons suffering from infectious diseases in industrialized countries.For example, in the United States recorded a sharp increase in the incidence of tuberculosis . Very greatly increased the number of infection of sexually transmitted diseases - chlamydia, gonorrhea and syphilis .

Unfortunately, even though the quality of life in the developed countries, the availability of effective antibiotics and the fairly common practice of vaccines - infectious disease mortality inferior to lead a cardio - vascular and oncological diseases.In developing African countries because of the constant malnutrition and non-basic sanitation, infectious diseases annually kill about ten million people.The largest number of deaths recorded among children.
