Reply To: Aeromonas Spp

Hi Prathana

Thank you for clarifying to me the infection site as gastro.

Query: has the source been investigated/identified?

Reflecting on: National IPC Guidelines: https://www.safetyandquality.gov.au/sites/default/files/2026-05/australian-guidelines-for-the-prevention-and-control-of-infection-in-healthcare.pdf/Aged Care IPC Guide: https://www.safetyandquality.gov.au/sites/default/files/resources/attachments/The-Aged-Care-Infection-Prevention-and-Control-Guide.pdf – while there is no specific match to Aeromonas spp – gastro management recomendations can be followed

Management – standard and contact precautions, isolation duration of illness (as possible), transmission precaution cleaning including increased frequency and use of registered neutral detergent and disinfectant. Management of contaminated linen and waste in accordance with WA guidelines. High alert for new cases – both resident and staff. Ensure unwell staff exclusion times.

As this meets the definition of outbreak, the Gastro Info Coordinators Handbook can be used: https://www.health.gov.au/sites/default/files/documents/2020/01/outbreak-coordinator-s-handbook-gastroenteritis-kit-for-aged-care.pdf

Re: Notification:

You are able to look up nationally notifiable infections on The National Notifiable Diseases List: https://www.cdc.gov.au/diseases/surveillance-systems-and-networks/national-notifiable-diseases-surveillance-system-nndss#the-national-notifiable-diseases-list

As the situation meets the definition of an outbreak, contacting the local PHU is advised.

Hope this is helpful

Regards Carrie
