Understanding the influence of non-susceptible hosts on vector-borne disease transmission is an important epidemiological problem. However, investigation of its impact can be complicated by uncertainty in the location of the hosts. Estimating the risk of transmission of African horse sickness (AHS) in Great Britain (GB), a virus transmitted by Culicoides biting midges, provides an insightful ex...

Over the past 500 years, North America has been the site of ongoing mixing of Native Americans, European settlers, and Africans (brought largely by the trans-Atlantic slave trade), shaping the early history of what became the United States. We studied the genetic ancestry of 5,269 self-described African Americans, 8,663 Latinos, and 148,789 European Americans who are 23andMe customers and show ...

Although clinicians are encouraged to be more sensitive to cultural factors in the diagnosis and treatment of mental disorders, as evidenced by the significant changes in the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994), little information is provided to help them determine which aspects of culture are important to the mental health of ...

African trypanosomiasis is the collective name for a wide variety of trypanosome infections that affect humans and livestock. In recent years, experimental mice infection models have provided new insights into both human and animal trypanosomiasis. Mouse models seem to be a valuable and versatile tool in trypanosomiasis-associated pathology and immunology research and highlight the variety show...

ity communities, and to adapt site attributes to better reflect ethnic preferences, increased use by Hispanics and Asians is prompting managers to search for innovative ways to respond to the different natural resource values held by minority visitors (Tierney et al. 1998, Chavez 2001, Chavez 2002). For example, in southern California, some national forest recreation managers have implemented “...

OBJECTIVE The design, overall methods, and major phenotypes for the all-African-American Jackson Heart Study (JHS) are detailed. METHODS Participants were enrolled from the three counties that make up the Jackson, Mississippi metropolitan area. Relatives of selected participants were recruited to develop a large, nested family cohort. Participants provided extensive medical and social history...

OBJECTIVE Identify factors associated with health-related quality of life (HRQOL) among African Americans with multiple sclerosis (MS). DESIGN A survey cohort was recruited from the Registry of the North American Research Committee On Multiple Sclerosis (NARCOMS) Project. Data were collected from 131 African Americans with MS, with 111 participants providing all data needed for analyses of ph...

The involvement of African Americans in research has long been expressed as a concern by the scientific community. While efforts have been undertaken to identify factors inhibiting the participation of African Americans in health-related research, few efforts have been undertaken to have highlight factors associated with their engagement of health-related research. An exploratory study of facto...

African horse sickness (AHS) is a hemorrhagic viral fever of horses. It is the only equine disease for which the World Organization for Animal Health has introduced specific guidelines for member countries seeking official recognition of disease-free status. Since 1997, South Africa has maintained an AHS controlled area; however, sporadic outbreaks of AHS have occurred in this area. We compared...
