Communicable Diseases

COMMUNICABLE DISEASES

· In perfect balance there will be NO ISSUES

· If microorganisms are in WRONG place and TOO MANY it will cause problems

· Resistance and immunity DECREASES it will to INFECTION ecological model shows the imbalances

· Infectious disease: cause by a pathogen

· Communicable disease: transferred from one person to another

Contagious disease: HIGHLY communicable

Carrier: person who carries the pathogen but asymptomatic

Contact: close association with infected person

Sporadic: occasionally and irregular pattern (Measles, botulism, tetanus, dengue)

Endemic: constantly present in a population, country or community

Epidemic: sudden rise, short-period of time of increase number (dengue, measles, zika, ebola, cholera)

Pandemic: Worldwide

Acute diseases: develops rapidly, lasts a short time (measles, mumps, influenza)

Chronic diseases: blood-borne, slowly and last longer (Tb, leprosy)

Subacute: fast onset, takes a while (bacterial endocarditis)

Latent diseases: causative agent remain inactive. Becomes active to produce symptoms of the disease (chickenpox to shingles to very painful)

· Chickenpox to dormant along the nerves to herpes zoster to VERY painful

Local infection: small area of a body (one area)

Generalized (systemic) infection: whole body (lymphatic and blood) (measles)

Focal infection: Local infection that spread but is CONFINED to specific areas of the body

Primary infection: acute infection that causes initial illness

Secondary infection: opportunistic pathogens, when immunity is weakened

Subclinical (inapparent infection): does not cause any noticeable illness (low velorence pathogen or high immunity)

STAGES OF DISEASE

Incubation: initial spread (can be communicable on some Measles)

Prodromal: early, mild appearance of symptoms

Period of illness: manifest usually symptoms of the disease, WBC increase or decrease

Period of decline: symptoms goes down, can still be communicable (chickenpox)

· Only prodromal or incubation only if infection is mediated by IMMUNE SYSTEM

Incidence: NUMBER of cases divided by total number of immune population

Prevalence: TOTAL number of all cases (OLD and NEW)
