The current Ebola virus disease (EVD) outbreak in West Africa is the worst epidemic of Ebola since the first case was officially reported in 1976. The “traveling” of the infection from Guinea and Liberia to other parts of West Africa, Europe, and America has caused anxiety and panic. To control exportation and importation of EVD, the World Health Organization recommends exit screening in Guinea...
It was in Freetown, Sierra Leone, that the malaria mosquito Anopheles coastalis, now known as Anopheles gambiae, was first discovered as the vector of malaria, in 1899. That discovery led to a pioneering vector research in Sierra Leone and neighbouring Liberia, where mosquito species were extensively characterized. Unfortunately, the decade long civil conflicts of the 1990s, in both countries, ...
1 SUMMARY A total of 17 145 confirmed, probable, and suspected cases of Ebola virus disease (EVD) have been reported in five affected countries (Guinea, Liberia, Mali, Sierra Leone, and the United States of America) and three previously affected countries (Nigeria, Senegal and Spain) up to the end of 30 November. There have been 6070 reported deaths. Reported case incidence is slightly increasi...
The 2013-2015 Ebola virus disease (EVD) epidemic is caused by the Makona variant of Ebola virus (EBOV). Early in the epidemic, genome sequencing provided insights into virus evolution and transmission and offered important information for outbreak response. Here, we analyze sequences from 232 patients sampled over 7 months in Sierra Leone, along with 86 previously released genomes from earlier ...
BACKGROUND Ebola virus disease has taken a toll on more than 8,000 lives in West Africa in 2014. The most affected countries are Guinea, Liberia, and Sierra Leone. The number of people infected by Ebola in Sierra Leone surpassed that of Liberia in the last month in this year and almost half of human cases are distributed in this country. DISCUSSION The ignorance on Ebola among people, includi...
International aid agencies have vowed to carry on working in Guinea after health workers were attacked and killed last week. Government reports said that health workers were attacked with stones and machetes in the village of Wome in the south of the country. Some members of the team, which was raising awareness about Ebola virus disease, managed to escape, but eight people, including health wo...
This case study is adapted from events that occurred along the Sierra Leone and Guinea land border during the 2014-2016 Ebola epidemic in West Africa. The response activities involved Sierra Leone and Guinea officials, along with assistance from U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organisation (WHO). This case study builds upon an understanding of basic su...
The 2014 epidemic of the Ebola virus is governed by a genetically diverse viral population. In the early Sierra Leone outbreak, a recent study has identified new mutations that generate genetically distinct sequence clades [1]. Here we find evidence that major Sierra Leone clades have systematic differences in growth rate and reproduction number. If this growth heterogeneity remains stable, it ...
The objectives of this study were to identify decision makers for FGM and determine whether medicalization takes place in Sierra Leone. Structured interviews were conducted with 310 randomly selected girls between 10 and 20 years in Bombali and Port Loko Districts in Northern Sierra Leone. The average age of the girls in this sample was 14 years, 61% had undergone FGM at an average age of 7.7 y...
Lassa virus (LASV) is endemic to parts of West Africa and causes highly fatal hemorrhagic fever. The multimammate rat (Mastomys natalensis) is the only known reservoir of LASV. Most human infections result from zoonotic transmission. The very diverse LASV genome has 4 major lineages associated with different geographic locations. We used reverse transcription PCR and resequencing microarrays to...
