Surveillance for Infectious and Communicable Diseases
To gather the who, when, what, and where to determine why
Systematically collect, organize, and analyze data for a defined disease
Surveillance for agents of bioterrorism—anthrax, smallpox
List of Reportable Diseases- varies by state
National Notifiable Diseases- infectious and non-infectious
Populations at increased risk for transmission and infection
Children
Older adults
Immunosuppressed
High-risk lifestyles
Travelers
Health care workers
most probable cause of the increase in new emerging infectious diseases
Activities or behavior of humans, including changes in the environment
Emerging infections
Those in which the incidence has increased in the past two decades or has the potential to increase in the future
Airborne infections examples
Measles
Chicken pox
TB
Pertussis
Influenza
SARS
Foodborne infections
Salmonella
Hepatitis A
Trichinosis

STDs
Vaccine preventable diseases
Measles
Mumps
Rubella
Pertussis
Influenza
Polio
Tetanus
Incubation/latency period
time interval between invasion by infectious agent and symptoms
Prodromal period
here the pathogen continues to multiply, and the host begins to experience general signs and symptoms of illness
Too general to know what it is that’s making you sick
Period of illness
the signs and symptoms of disease are most obvious and severe
Period of decline
treatment or sickness passed
Replication stops, the number of pathogen particles begins to decrease, and the signs and symptoms of illness begin to decline
communicable period
time interval during which an infectious agent may be transferred directly or indirectly from an infected person
Can happen in any stage
Active immunity
Antibodies synthesized by the body in response to antigen stimulation
NATURAL active immunity
contact with an antigen through exposure
ARTIFICIAL active immunity
immunization with an antigen
Passive immunity
antibodies produced in one individual and transferred to another
NATURAL passive immunity
immunity from the placenta transferred from mother to child
ARTIFICIAL passive immunity
injection of serum from an immune human or animal i.e. , gamma globulin
Herd immunity
Type of immunity in which a large proportion of people in a population are not susceptible to a communicable disease, and the few susceptible people will not be likely to be exposed and contract the illness
Flu
Influenza is a viral respiratory infection
Transmission is airborne
Vaccines available!
Symptoms of flu
temp 100+
cough
sore throat
underlying condition that increases risk
