Historical Mortality Dynamics on the Baja California Peninsula : Marriage, Mining Booms, Migration, and Infectious Disease.

Historical demographic research shows that the factors influencing mortality risk are labile across time and space. This is particularly true for datasets that span societal transitions. Here, we seek to understand how marriage, migration, and the local economy influenced mortality dynamics in a rapidly changing environment characterized by high in-migration and male-biased sex ratios.

Do Monkeypox Exposures Vary by Ethnicity? Comparison of Aka and Bantu Suspected Monkeypox Cases.

In 2017, a monkeypox outbreak occurred in Likouala Department, Republic of the Congo. Many of the affected individuals were of Aka ethnicity, hunter-gatherers indigenous to Central Africa who have worse health outcomes in comparison with other forest-dwelling peoples. To test the hypothesis that Aka people have different risk factors for monkeypox, we analyzed questionnaire data for 39 suspected cases, comparing Aka and Bantu groups.

Epidemiologic and Ecologic Investigations of Monkeypox, Likouala Department, Republic of the Congo, 2017.

Monkeypox, caused by a zoonotic orthopoxvirus, is endemic in Central and West Africa. Monkeypox has been sporadically reported in the Republic of the Congo. During March 22-April 5, 2017, we investigated 43 suspected human monkeypox cases.

Strengthening of Surveillance during Monkeypox Outbreak, Republic of the Congo, 2017.

Reports of 10 suspected cases of monkeypox in Likouala Department, Republic of the Congo, triggered an investigation and response in March 2017 that included community education and surveillance strengthening. Increasing numbers of outbreaks suggest that monkeypox virus is becoming a more prevalent human pathogen. Diverse approaches are necessary for disease control and prevention.

Knowledge Gained and Retained from a Video-Centered, Community-Based Intervention for Ebola Prevention, Congo.

There are few effective communication interventions to respond to Ebola Virus Disease (EVD) outbreaks, and their development is a continuing challenge. The largest outbreak of EVD was first recognized in 2014 and once again highlighted the need for health education communication campaigns. EVD emergence and transmission are associated with behaviors that increase exposure to infected individuals and infected wildlife.

Presumptive risk factors for monkeypox in rural communities in the Democratic Republic of the Congo.

Monkeypox virus (MPXV), a close relative of Variola virus, is a zoonotic virus with an unknown reservoir. Interaction with infected wildlife, bites from peri-domestic animals, and bushmeat hunting are hypothesized routes of infection from wildlife to humans. Using a Risk Questionnaire, performed in monkeypox-affected areas of rural Democratic Republic of the Congo, we describe the lifestyles and demographics associated with presumptive risk factors for MPXV infection.

Collection and Utilization of Animal Carcasses Associated with zoonotic Disease in Tshuapa District, the Democratic Republic of the Congo, 2012.

The collection and consumption of animal carcasses is a common activity in forested areas of the Congo River basin and creates sustainability, conservation, and health concerns. Residents of the Tshuapa District reported collecting the remains of 5,878 animals from >30 species when surveyed about their wildlife consumption habits. Carcasses were discovered in varying degrees of decomposition and were often consumed at home or sold in local markets.

Detection of human monkeypox in the Republic of the Congo following intensive community education.

Monkeypox is an acute viral infection with a clinical course resembling smallpox. It is endemic in northern and central Democratic Republic of the Congo (DRC), but it is reported only sporadically in neighboring Republic of the Congo (ROC). In October 2009, interethnic violence in northwestern DRC precipitated the movement of refugees across the Ubangi River into ROC.

Assessing the effectiveness of a community intervention for monkeypox prevention in the Congo basin.

Background: In areas where health resources are limited, community participation in the recognition and reporting of disease hazards is critical for the identification of outbreaks. This is particularly true for zoonotic diseases such as monkeypox that principally affect people living in remote areas with few health services. Here we report the findings of an evaluation measuring the effectiveness of a film-based community outreach program designed to improve the understanding of monkeypox symptoms, transmission and prevention, by residents of the Republic of the Congo (ROC) who are at risk for disease acquisition.
