Summary
Malaria cases in U.S. service members decreased in 2019, with Plasmodium falciparum being the most common cause. Healthcare providers must remain vigilant for malaria symptoms, even outside endemic regions.
Area of Science:
- Military Health
- Infectious Diseases
- Epidemiology
Background:
- Malaria poses a significant health risk to U.S. service members deployed to or traveling in endemic areas.
- Maintaining vigilance for malaria is crucial for military healthcare providers, especially when service members are outside endemic zones.
Purpose of the Study:
- To analyze the trends and characteristics of malaria cases among U.S. service members from 2012-2019.
- To identify the primary causative agents and geographical sources of malaria infections in this population.
Main Methods:
- Retrospective analysis of malaria surveillance data for U.S. service members.
- Categorization of cases based on causative Plasmodium species, geographical origin, and year of diagnosis.
Main Results:
- A 40.7% decrease in malaria cases was observed in 2019 compared to 2018, with 35 total cases.
- Plasmodium falciparum remained the predominant species, accounting for 54.3% of cases in 2019, the highest percentage in a decade.
- Cases attributed to unspecified/other sources were 31.4%, while Plasmodium vivax cases were at a 10-year low (14.3%).
- Diagnoses occurred across 17 medical facilities in the U.S., Germany, Afghanistan, and Korea.
Conclusions:
- While overall malaria cases decreased, Plasmodium falciparum remains a significant concern.
- Reduced cases in Afghanistan likely influenced the overall decline due to U.S. force withdrawals.
- Continued medical provider awareness is essential for timely malaria diagnosis and management in military personnel.

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
