Morbidity and Mortality Weekly Report. Surveillance Summaries (Washington, D.C. : 2002)
|March 2, 2012
Summary
Malaria cases in the U.S. increased in 2010, with most cases imported by travelers. Prevention strategies, especially for pregnant women and those visiting friends and relatives, need improvement.
Area of Science:
- Medical Entomology
- Infectious Diseases
- Parasitology
Background:
- Malaria is transmitted by Anopheles mosquitoes, with most U.S. cases occurring in travelers.
- Surveillance identifies local transmission and informs prevention for travelers.
Purpose of the Study:
- To summarize malaria cases in the U.S. with symptom onset in 2010.
- To analyze trends in malaria cases and prevention adherence.
Main Methods:
- Data collected through the National Malaria Surveillance System (NMSS) and National Notifiable Diseases Surveillance System (NNDSS).
- Case investigations conducted by local and state health departments.
- Analysis of reported malaria cases, including species, origin, and treatment adherence.
Main Results:
- 1,691 malaria cases reported in 2010, a 14% increase from 2009.
- Plasmodium falciparum was the most common species (58%).
- Only 5% of U.S. civilian travelers adhered to chemoprophylaxis; 5% of pregnant women adhered.
Conclusions:
- 2010 saw the highest number of reported malaria cases since 1980.
- Inadequate prevention measures by travelers, particularly VFRs and pregnant women, contribute to imported cases.
- Improved, targeted prevention strategies are crucial to reduce malaria burden in the U.S.

01:26Principles of Disease Surveillance
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
01:23Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
00:58Symbiosis
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...
