Question

Fifty years ago many people believed the age-old battle of humans against infectious disease was virtually over, with humankind the winners. The events of the past decades have proved this wrong. At least a dozen "new" diseases have been identified (such as AIDS, Legionnaire disease, SARS, and hantavirus pulmonary syndrome), and traditional diseases that appeared to be "on their way out" (such as malaria and tuberculosis) are resurging. Globally, infectious diseases remain among the leading causes of death. Clearly, the battle has not been won.

1.    How can you define emerging and re-emerging infectious diseases? Give examples.

2.    What are the main causes of the re-emergence of an infectious disease?

3.    What is the global and regional situation regarding emerging and re-emerging infectious diseases?

Answer 1

1, Emerging infectious disease is an infection that occurs to people or within geographic range make threaten to the future. It can be caused by an unknown infectious agent.
Example: Pandemic H1N1 influenza, Lyme disease
Reemerging infectious disease is a disease that creates major health problems at once, declined and again becoming health problems for the people. Example; Malaria
2, Remerging disease are foodborne, a waterborne disease caused by multiresistant organism causing major threatens to the population.
3, Globally infectious disease is a leading cause of death. emerging infectious disease not occurred in a human before and affected again only a small number of people with AIDS and like an emerging infectious disease, this found in human history but recognized due to infectious agents. Remerging infectious disease is a major health problem globally and declined gradually, but again increases within the significant proportion of the people.
