The Disease Notifications screen provides a list of notifiable disease cases within your Local Government Authority. The data is based on the Western Australian Notifiable Infectious Disease Database (WANIDD) that is managed by the Department of Health. Only a subset of the data is made available to protect the patient’s confidentiality. The Disease Notifications are uploaded regularly by the Medical Entomology team within the Department of Health. Disease Notifications can be downloaded by selecting the Reports menu and choosing the View Notifications option.
Select the View Notifications report
This reporting system is based on a number of filters and the results will depend on which filters are activated and the categories selected. Upon selecting View Notifications you will be presented with a list of filters. Thus, the results generated will depend upon the filters selected. Results can be filtered by the following categories:
- Medical Entomology (ME) Region – based on mosquito populations and distribution as well as health risks of mosquito-borne diseases;
- CLAG – Contiguous Local Authority Groups;
- LGA – Local Government Authority;
- Locality – a list of suburbs and Aboriginal Communities;
- Organism – the disease of interest;
- Start Date – date of earliest recorded human disease case;
- End Date – date of latest recorded human disease case;
- Age Group (by category) – to examine cases across different age categories; and
- ID – If you know the WANIDD case number.
Each page is split into two sections, the filters to identify cases of interest and the listed results based on the filters. By pressing on the “Filter” button, the results under the form will be updated to show the records that match your criteria.
Disease Notification Filters
The Disease Notifications report
To get started, you need to select some of the filters to reduce the number of human disease notifications displayed. You can choose options under one or more of the filters to reduce the number of results. The more specific you are, the more likely you will obtain the notifications you are looking for. The first filter includes the Medical Entomology (ME) Region. These regions are based on mosquito abundance and distribution and on the known likelihood of contracting a mosquito-borne disease across Western Australia. The list of regions is listed from North to South of Western Australia following including the:
- SW – Peel;
- SW – Leschenault;
- SW – Geographe;
- SW – Elsewhere
- Great Southern; and
- Indian Ocean Territories.

The second filter allows you to reduce the number of human cases report by selecting a single Contiguous Local Authorities Group (CLAG) from the drop down list. This filter will only work for Local Governments that have formed a CLAG with the Department of Health.

The third filter allows you to select the Local Government Authority from which the human notifications are assigned. In most instances you will only be able to view notifications from within your LGA, but those LG’s that have formed a CLAG will have the option to select LGA’s within the CLAG.
The Local Government Authority filter
The fourth filter allows you to select a specific suburb within your Local Government Authority. The suburbs are listed in alphabetical order and you can use the scroll bar to move up and down the list of suburbs.
The Suburb filter
The fifth filter allows you to search on the organism (Disease) that you wish to find notifications for. Four options are currently available including:
- Ross River virus;
- Barmah Forest virus;
- Murray Valley encephalitis virus; and
- Kunjin virus.
The organism filter
The sixth and seventh filters allow you to choose the start and end date for human notifications. These filters will help reduce the number of case reports displayed and can be used to examine trends year by year. The text in each filter can be written over by clicking on the field.
Start and End filters
The eighth filter allows you to choose the age range of patients to look at trends across different age classes. Results are present in five year categories to 85 years of age. All notifications from patients older than 85 years of age are clumped together.
The age group filter
The last filter is the ID filter. If you know the WANIDD case code for a specific patient, this can be typed into the ID filter to pull up a single record of interest.
The WANIDD ID filter
Once you are happy with your selection of filters, click the blue Filter button to obtain a list of human cases that fall within the parameters selected.
Depending on the number of filters selected, the list of returned notifications will vary. The more specific you are the fewer results you will have returned. Results are displayed in Chronological order from newest to oldest. Across the top of the table of results is a list of heading including:
- ID – the WANIDD record number specific to each human case;
- Suburb – the suburb where the resident was infected by a mosquito-borne virus;
- LGA – the Local Government Authority in which the resident dwells;
- ME Region – the Region in which the patient lives;
- CLAG – the name of the CLAG if the LGA has formed a CLAG;
- ESD ODOO – Estimated Date of Onset of the disease;
- Organism – the disease diagnosed in the patient; and
- Age Group – the age group that the patient falls into.
Results from a filtered search for Ross River Virus cases in the Town of Claremont over a two year period only returned two cases
If multiple pages of human notifications are found, page numbers are displayed at the bottom of the first table. You can select any page number to jump to records recorded on that page. Once again, the list of returned records is listed from most recent to oldest dependant on the start and end dates selected. Alternatively you can jump to the last record by selecting the arrow at the far right to the page numbers.
