Hypothesis
What factors contributed to the reemergence of Plasmodium vivax malaria in the Republic of Korea?
Conclusion
Plasmodium vivax malaria reemerged in Korea in 1993, with cases tripling each year, but all cases in U.S. troops were successfully treated.
Supporting Evidence
- More than 1,600 cases of malaria were reported in 1997.
- All 27 cases in U.S. troops resolved uneventfully with chloroquine/primaquine therapy.
- Malaria cases began to occur in late spring or early summer, before the weather was warm enough for transmission.
Takeaway
Malaria came back in Korea after many years, but the soldiers who got it were treated and got better.
Methodology
The study involved monitoring malaria cases among U.S. troops and Korean soldiers, along with treatment outcomes.
Potential Biases
Potential bias in reporting due to security concerns limiting data release.
Limitations
The study does not provide detailed data on civilian cases or the full extent of indigenous transmission.
Participant Demographics
All cases were in men aged 19 to 40 years, with a median age of 21.5 years.
