BIO 550 Week 2 Assignment Disease Outbreak Report

The Centers
for Disease Control (CDC) collects and disseminates information about outbreaks
of disease. H1N1, SARS, and West Nile virus are just a few of the disease
outbreaks that the CDC has reported. You have been called upon to lead one of
the investigations. Select a disease outbreak for which you will lead an
investigation.

In a report
of 750-1000-words, present the following information:

Identify
and describe the necessary steps to be taken for an investigation of the
disease outbreak.

For each of
the three prevention levels, provide at least two examples of prevention for
this disease.

Describe
the criteria to be met before screening for this disease.

Describe
how the effectiveness of the screening program will be evaluated.

You are
required to use a minimum of three scholarly resources.

Prepare
this assignment according to the APA guidelines found in the APA Style Guide,
located in the Student Success Center. An abstract is not required.

The public health response to outbreaks of norovirus is determined by state or territory legislation, local reporting requirements and available resources. Public health agencies will seek to determine the nature of the outbreak to define their role in the investigation.

In institutional outbreaks that are suspected to be person-to-person spread, it may be more appropriate for the facility to manage the

outbreak with advice or support from the PHU or Environmental Health Officers (EHO), as required. On the other hand, public health agencies will need to rapidly investigate and manage outbreaks of food- or waterborne disease, as intervention can reduce human illness, and they can have important policy implications for government.

7.1 Assessment of a suspected outbreak

Notifications or reports of an outbreak received by a PHU will need initial assessment. This may be done by public health nurses or public health officers. Initial information collected should include:

• the time the outbreak began
• the total number of cases and unaffected people to calculate the proportion of people affected
• symptoms and duration of illness
• type of outbreak setting
• if food is implicated
• results of any laboratory tests that may have been done.

A key means of assessing the initial features of an outbreak is to assemble a simple line-list. A line-list records the basic details about each suspected case. This includes:

• the time and date of when the illness began
• duration of illness
• information on key symptoms
• whether laboratory tests have been conducted
• any key exposures related to illness.

The use of a line-list continues throughout an investigation of an outbreak, but is particularly important in the initial phase to allow proper characterisation of the outbreak. From the line-list, it is possible to:

• develop an epidemic curve to determine if the outbreak is suggestive of a point-source or person-to-person spread
• review symptoms and duration of illness to determine if the illness is consistent with norovirus
• follow up and review any initial laboratory tests that may have been conducted
• develop a preliminary case definition for cases in the outbreak to assist with counting further infections
• review information available, in particular the type of outbreak setting, characteristics of cases and attack rate of illness.

7.2 Criteria for starting an investigation

When to start an investigation on a suspected outbreak of norovirus will be determined by the:

• type of outbreak setting
• number of affected persons
• severity (morbidity, e.g. hospitalisation and mortality history) of cases
• suspicion of a foodborne source.

Two or more cases of diarrhoea and/or vomiting in a 24 hour period in an institution or among a group of people who shared a common exposure or food source should be suspected as constituting an outbreak and an assessment or investigation commenced. An outbreak of infectious gastroenteritis, such as that caused by norovirus, is often diagnosed presumptively on clinical grounds from characteristic epidemiological features. In fact, the PHU may choose not to investigate person-to-person outbreaks, but focus on providing advice on infection control measures. Outbreak surveillance in Australia shows that ACFs and hospitals are the leading setting for norovirus outbreaks, which are mainly ascribed to person-to-person transmission. On the other hand, PHUs will investigate suspected foodborne norovirus outbreaks. Norovirus outbreaks transmitted by contaminated food should not be ruled out if an outbreak occurs in an institution.
