A practical community-based response strategy to interrupt Ebola transmission in sierra Leone, 2014-2015.

Background: The Ebola virus disease spread rapidly in West Africa in 2014, leading to the loss of thousands of lives. Community engagement was one of the key strategies to interrupt Ebola transmission, and practical community level measures needed to be explored in the field and tailored to the specific context of communities.

Methods: First, community-level education on Ebola virus disease (EVD) prevention was launched for the community's social mobilizers in six districts in Sierra Leone beginning in November 2014.

Rapid assessment of knowledge, attitudes, practices, and risk perception related to the prevention and control of Ebola virus disease in three communities of Sierra Leone.

Background: The recent outbreak of the Ebola virus disease (EVD) in Sierra Leone has been characterized by the World Health Organization as one of the most challenging EVD outbreaks to date. The first confirmed case in Sierra Leone was a young woman who was admitted to a government hospital in Kenema following a miscarriage on 24 May 2014. On 5 January 2015, intensified training for an EVD response project was initiated at the medical university of Sierra Leone in Jui.

Knowledge and attitudes about Ebola vaccine among the general population in Sierra Leone.

Background: Clinical trials of Ebola vaccine are ongoing. Before it becomes commercially available, understanding the Ebola vaccine-related knowledge and attitude of the general population is imperative to developing an effective vaccine coverage strategy.

Methods: We conducted a survey including 400 participants from general communities of the West Area Rural District, Sierra Leone.

Soil respiration and carbon loss relationship with temperature and land use conversion in freeze-thaw agricultural area.

Soil respiration (Rs) was hypothesized to have a special response pattern to soil temperature and land use conversion in the freeze-thaw area. The Rs differences of eight types of land use conversions during agricultural development were observed and the impacts of Rs on soil organic carbon (SOC) loss were assessed. The land use conversions during last three decades were categorized into eight types, and the 141 SOC sampling sites were grouped by conversion type.

Effects of land use changes on the ecosystem service values of a reclamation farm in northeast China.

Intensive agricultural development can change land use, which can further affect regional ecosystem services and functions. With the rapid growth of the population and the national demand for food, the northeast of China, which is located in the high latitudes, has experienced four agricultural developments since the 1950s. The original wetlands of this area were developed for farmland.
