Where do emerging disease get started

They can originate from unknown sources, animal sources, or even biological warfare.

What modern factors increase risk for widespread emerging diseases

Global travel, population density, encroachment into new environments, misused antibiotics, and even bioterrorism.

What is a re-emerging disease

An infectious disease that reoccurs after it has once been eradicared

what are some examples of re-ermerging diseases

TB, pertussis, and diptheria.

What are the primary preventions for emerging diseases

goal is to decrease risk or exposure of individual or community to disease

What are the secondary preventions for emerging diseases

goal is to indentify indivduals in early stage of the disease process to limit future disability and prevent the spread of disease

What are the tertiary preventions for emerging diseases

goal is to return individual or community to an optimal level of functioning.

Prodromal, paroxysmal, and convalescent

What happens during the prodrmal phase

Cold symptoms, nasal drainage, sneezing, runny eyes, cough low grade fever, after 1-2 weeks cough becomes more sever, most infectious stage

What happens in the paroxsymal stage

(4-6 weeks) Coughing attacjs (mostl common at night) consisting of short rapid coughs followed by sudden inspiration associated with a high pitched sound (whoop). suring coughing spells cheeks become flushed or cyanotic, eyes buldge and tongue protrudes

What happens in the convalescent stage

(1-2 months) The cough becomes milder and less frequent during this phase. If a person develops an upper respiratory infection such as bronchitis during the third stage, the paroxysms will increase. Despite the cough, people are usually not infectious at this point in the course of the disease.

What is the treatmen for Pertussis

Antibiotics - erythromycin, clarithromycin, azithomycin,
