Malaria in migrants and travellers
1Global EIS Division, Centers for Disease Control, Atlanta, Georgia 30333.
Summary
Imported malaria cases are rising globally due to increased travel and migration. Travelers failing to prevent infection and infected vectors contribute to this growing public health concern.
Area of Science:
- Global Health
- Infectious Diseases
- Epidemiology
Background:
- Imported malaria presents a significant and increasing global health challenge.
- Factors contributing to this rise include increased international travel and migration.
- Resurgence of malaria in previously cleared regions also plays a role.
Purpose of the Study:
- To analyze the contributing factors to the growing incidence of imported malaria.
- To highlight the role of international travel and migration in malaria spread.
- To emphasize the importance of preventative measures for travelers.
Main Methods:
- This study is a review and analysis of current trends in imported malaria.
- Data on travel patterns and malaria resurgence were examined.
- Case studies on traveler-acquired malaria were considered.
Main Results:
- Increased global travel and migration are primary drivers of imported malaria.
- Migrants are significant in reintroducing malaria into malaria-free areas.
- Inadequate preventive measures by travelers are a key factor in infection.
- Malaria vectors traveling with humans also facilitate disease spread.
Conclusions:
- Imported malaria is a growing threat requiring international attention.
- Enhanced traveler education on malaria prevention is crucial.
- Stricter vector control measures during travel are necessary.
- Continued surveillance and control efforts are vital in endemic and non-endemic regions.
