Malaria in Sydney, Australia: Lessons learned from case management.

Area of Science:

• Pediatric infectious diseases
• Tropical medicine
• Clinical diagnostics

Background:

• Malaria remains a significant global health concern, posing diagnostic challenges in non-endemic settings.
• Early and accurate diagnosis is critical for effective treatment and preventing severe outcomes in children.

Purpose of the Study:

• To characterize the clinical presentation and epidemiological profile of pediatric malaria cases diagnosed in Australia.
• To inform diagnostic strategies and clinical awareness for malaria in children.

Main Methods:

• Retrospective review of medical records for children diagnosed with malaria.
• Data collected from The Children's Hospital Westmead between 2000 and 2010.

Main Results:

• Forty pediatric malaria cases were identified over 11 years.
• Fever was present in 75% of cases, but 20% were asymptomatic.
• Common Plasmodium species included P. falciparum (68%); P. vivax was also identified.
• Median diagnosis time was 32 days post-arrival for refugees and immigrants.

Conclusions:

• Malaria symptoms in children are often non-specific, necessitating high clinical suspicion.
• Diagnostic vigilance is essential for children with any potential malaria exposure history.
• Asymptomatic parasitemia should be considered in recent migrants from endemic regions.
