provide information for control eradication and preventative measures
types of surveillance
active or passive depending on method of data collected
passive surveillance
individual providers periodically submit reports to central hub
advantages and disadvantages of passive surveillance
advantage = lower cost per case, good for long term trend analysis, simpler than active surveillance
disadvantages = poor compliance, under reporting can lead to low validity of data
active surveillance
purposeful and comprehensive searching for evidence of disease in population or for confirming the absence of such disease
advantages and disadvantages of active surveillance
advantages = detects more cases, increase certainty of disease freedom if no cases are found, lower likelihood of underreporting more credible system international trade
disadvantage = high cost per cases, labor instesive
What is the monitor place for a disease that is not present
monitor/passive surveillance
what is the monitor plan for a disease introduces or detected?
active surveillance
what is the monitory plan for a disease not present
active then back to passive
