Transfusion-induced malaria from an asymptomatic carrier
Abstract:
An asymptomatic malaria carrier who satisfied the currently recommended standards and criteria of the American Association of Blood Banks for blood donation was the source of the transfusion-induced malaria in this study. The risk of transfusion-induced malaria remains a very real threat in the United States. Any case of unexplained fever following transfusion should be considered as possibly caused by malaria. Delay of the proper diagnosis may be due to unfamiliarity of medical personnel with diagnostic criteria for malaria. Persons who give a history of having resided for long periods in malarious regions, even though they have remained asymptomatic for many years while residing in a malaria free area may still carry the more persistent malarial species and, therefore, should be rejected as donors of whole blood.
Insights
Asymptomatic malaria carriers can transmit the disease through blood transfusions, posing a risk in the United States. Individuals with a history of living in malaria-endemic areas should be carefully screened as blood donors.
Area of Science:
- Infectious Diseases
- Transfusion Medicine
- Public Health
Background:
- Malaria transmission through blood transfusion presents a persistent risk, even in non-endemic regions.
- Current blood donation criteria may not adequately identify all asymptomatic malaria carriers.
- Unexplained fever post-transfusion necessitates consideration of malaria.
Observation:
- A case study identified an asymptomatic malaria carrier meeting American Association of Blood Banks (AABB) standards as the source of transfusion-induced malaria.
- The donor was asymptomatic despite residing in a malaria-free area for an extended period.
Findings:
- Asymptomatic individuals can harbor persistent malarial species capable of transmission.
- Existing screening protocols may not detect all carriers of these persistent species.
Implications:
- Healthcare providers must consider malaria in unexplained post-transfusion fevers.
- Stricter donor screening for individuals with a history of residing in malarious regions is crucial.
- Enhanced diagnostic awareness and criteria are needed to prevent transfusion-transmitted malaria.
