The scale of the current outbreak of Ebola virus disease in west Africa is staggering. Thousands of infections and deaths have been reported in recent months, and unless major changes occur in the situation, incidence of Ebola virus disease has been projected to continue to grow and cumulative incidence to exceed 20 000 by November. A humanitarian crisis that stretches far beyond the impact of ...

During the 2001-2002 outbreak in Gabon, we observed that several dogs were highly exposed to Ebola virus by eating infected dead animals. To examine whether these animals became infected with Ebola virus, we sampled 439 dogs and screened them by Ebola virus-specific immunoglobulin (Ig) G assay, antigen detection, and viral polymerase chain reaction amplification. Seven (8.9%) of 79 samples from...

We determined complete viral genome sequences from three British healthcare workers infected with Ebola virus (EBOV) in Sierra Leone, directly from clinical samples. These sequences closely resemble those previously observed in the current Ebola virus disease outbreak in West Africa, with glycoprotein and polymerase genes showing the most sequence variation. Our data indicate that current PCR d...

The Ebola virus disease (EVD) is a rare and deadly disease affecting humans and other primates caused by infection with a virus of the family Filoviridae, genus Ebolavirus [1]. The March 2014 Ebola epidemic is the largest in history, affecting multiple countries in West Africa, with more than 11,301 deaths reported by the World Health Organization by March 2016. Methods based on polymerase chai...

During the 2014-2015 outbreak of Ebola virus disease in Guinea, 13 type 2 circulating vaccine-derived polioviruses (cVDPVs) were isolated from 6 polio patients and 7 healthy contacts. To clarify the genetic properties of cVDPVs and their emergence, we combined epidemiologic and virologic data for polio cases in Guinea. Deviation of public health resources to the Ebola outbreak disrupted polio v...

The current Ebola virus disease (Ebola) epidemic in West Africa is unprecedented in size and duration. Since the outbreak was recognized in March 2014, the World Health Organization (WHO) has reported 17,145 cases with 6,070 deaths, primarily in Guinea, Liberia, and Sierra Leone. Combined data show a case-fatality rate of approximately 70% in patients with a recorded outcome; a 30% survival rat...

The outbreak of Ebola virus disease (EVD) continues to spread through West Africa. Since the first report of EVD in March 2014, the number of cases has increased rapidly, with the fatality rate of >50%. The most prevalent Ebola virus belongs to the species of Zaire ebolavirus, with a fatality rate as high as 90%. Although there were cases introduced into other continents, Africa is the endemic ...

The variety of factors that contributed to the initial undetected spread of Ebola virus disease in West Africa during 2013-2016 and the difficulty controlling the outbreak once the etiology was identified highlight priorities for disease prevention, detection, and response. These factors include occurrence in a region recovering from civil instability and lacking experience with Ebola response;...

The Ebola virus disease is a severe viral haemorrhagic fever syndrome caused by Ebola virus. This disease is transmitted by direct contact with the body fluids of an infected person and objects contaminated with virus or infected animals, with a death rate close to 90% in humans. Recently, some mathematical models have been presented to analyse the spread of the 2014 Ebola outbreak in West Afri...
