Re-Emerging Infectious Diseases

Re-emerging infectious diseases are diseases that were formerly major public health concerns around the world or in a specific country, but have since fallen considerably, but are again re-emerging as a public health concern for a considerable segment of the population (malaria and tuberculosis are examples). Diseases that resurface after a long period of decline are known as re-emerging diseases. A collapse in public health measures for diseases that were formerly under control could lead to re-emergence. They can also occur when novel strains of previously identified disease-causing microbes emerge. Re-emergence is influenced by human behaviour. Infectious agents that had been known for some years had decreased to such low levels that they were no longer considered public health hazards; nonetheless, they are now showing higher trends in incidence or frequency over the world, or have appeared in regions where they had not previously been found.
