Summary

Malaria can spread between patients in hospitals if standard precautions are not followed. This study identified Plasmodium falciparum transmission between roommates without recent travel.

Area of Science:

  • Infectious Diseases
  • Molecular Epidemiology
  • Public Health

Background:

  • Malaria is a significant global health concern, primarily transmitted by mosquitoes.
  • Nosocomial malaria, or hospital-acquired malaria, is rare, particularly in non-endemic regions like the US.
  • Understanding transmission routes is crucial for preventing healthcare-associated infections.

Observation:

  • Two malaria patients diagnosed in the US lacked recent travel history.
  • Both patients were found to share a hospital room during their illness.
  • Molecular analysis revealed identical Plasmodium falciparum genotypes in both individuals.

Findings:

  • The study established molecular genotype identity of Plasmodium falciparum between the two patients.
  • This strongly suggests patient-to-patient transmission within the hospital setting.

  • Breaches in standard precautions involving blood inoculum are implicated as the likely transmission mechanism.

    • Implications:

    • Highlights the potential for malaria transmission in healthcare settings, even in non-endemic areas.
    • Underscores the importance of stringent adherence to infection control and standard precautions.
    • Emphasizes the need for heightened awareness and diagnostic vigilance for malaria in hospitalized patients, regardless of travel history.
