AbstractThe extraordinary progress in the knowledge of infectious disease, the discovery of antibiotics and effective vaccines are among the great achievement of the nineteenth and twentieth centuries. These achievement have led to a dramatic reduction in the levels of mortality from these diseases. According to the World Health Organization, the term "re-emerging infectious diseases" refers to infectious diseases, which although well known, have not been of recent public health importance. However, climate change, migration, changes in health services, antibiotic resistance, population increase, international travel, the increase in the number of immune-depressed patients ,etc have lead to the re-emergence of these diseases. The climate changes are exposing sectors of the population to inadequate fresh air, water, food and resources for survival which, in consequence, provoke increases in both internal and international migration. In this particular period in which we find ourselves, characterized by globalization, the international community has become aware that the re-emergence of these diseases poses an important risk for public health underlines the necessity to adopt appropriate strategies for their prevention and control. The re-emerging diseases of the twenty-first century are a serious problem for public health and even though there has been enormous progress in medical science and in the battle against infectious diseases, they are still a long way from being really brought under control. A well organized monitoring system would enable the epidemiological characteristics of the infectious diseases to be analyzed and the success or otherwise of preventive interventions to be precisely evaluated. For this reason, the World Health Organization and the European Union have discussed the formation of a collaborative network for the monitoring and control of re-emerging diseases and has initiated special programmes. The battle between humanity and infectious disease has a history lasting thousands of years and is destined to continue in the future emphasizing the need to adopt combined policies for the prevention and control of re-emerging diseases.
