This is a infection with a specific type of bacteria, Burkholderia pseudomallei which normally acts as a saprophyte in the soil and water of endemic areas such as Northern Australia, Southeast Asia, India, China, Thailand, Malaysia, Singapore, Papua New Guinea, New Caledonia.  The normal route of infection is via percutaneous inoculation of the skin surface or via inhalation and occasionally ingestion. The incubation period is from 1 to 24 days with an average of nine days.  The commonest manifestation is pneumonia or skin infection.

Unapparent infections by the causative bacterium can also occur and these are not covered by the SOP, which requires a clinical illness.

Is specific diagnostic evidence required to apply the SOP? – Yes.

This diagnosis is based on microbiological confirmation of the infection through microscopy, and culture, plus an appropriate pattern of clinical illness.  The relevant medical specialist for this condition would be an infectious disease physician.

Are there sub-factors that require specific information? – No.
