VII. Emerging and Re-emerging Infections Diseases

Emerging and re-emerging infections

The microbial world is complex, dynamic and constantly evolving. Infectious agents reproduce rapidly, mutate frequently, cross the species barrier between animal hosts and humans, and adapt with relative ease to their new environments. Because of these traits, infectious agents are able to alter their epidemiology, their virulence, and their susceptibility to anti-infective drugs. When disease ...

Human Emerging and Re-emerging Infections.

Emerging and re-emerging infectious diseases present tremendous challenges to the world’s medical and public health enterprise, highlighted by the recent Ebola epidemic in Africa, the recognition of serious birth defects due to Zika virus infections in the Western Hemisphere, and the fact that 3.2 billion people (nearly half the world’s population) continue to live in areas at risk of malaria t...

Emerging and Re-emerging Viral Infections

Natural focal diseases are caused by biological agents associated withspecific landscapes. The natural focus of such diseases is defined as anynatural ecosystem containing the pathogen’s population as an essentialcomponent. In such context, the agent circulates independently on humanpresence, and humans may become accidentally infected through contact with vectors or reservoirs....
