In 2014, Ebola hemorrhagic fever broke out in West Africa. As contact between China and West Africa is frequent, the possibility that Ebola virus would enter China was high. Thus, an external assessment of the quality of Ebola virus detection was organized by the National Center for Clinical Laboratories in China. Virus-like particles encapsulating known sequences of epidemic strains of Ebola v...
Crimean-Congo hemorrhagic fever (CCHF) is a disease that poses a great threat to public health owing to its high mortality rate (30-70%), mode of transmission and geographic distribution. Here, we report on a nine years-old Sudanese boy from Southern Kordofan State who presented with Jaundice, high-grade fever, severe headache, abdominal pain and a history of hematemesis. The diagnosis of CCHF ...
Crimean-Congo haemorrhagic fever (CCHF) is a tick-borne zoonotic disease. Over the past decade, CCHF cases in humans have emerged in Turkey and reemerged in the Balkan countries, Ukraine and Tajikistan. Occupational contact with infected livestock has been recognized as a common cause of the disease. A cross-sectional seroprevalence study in livestock was conducted in farming communities of an ...
Crimean-Congo hemorrhagic fever (CCHF) virus has attracted considerable attention recently and a number of phylogenetic studies have been published, based mostly on partial sequences of S and M RNA segments. In this study, available full-length S, M and L segment sequences of CCHF virus were checked for recombination. Similarity plots and bootscan analysis of the S segment suggested multiple re...
A patient with suspected malaria was hospitalized successively in 2 hospitals, first in Dakar, Senegal, then in Rennes, France, where tests diagnosed Crimean-Congo hemorrhagic fever. An international incident management group was set up in France and Senegal, which traced 181 contacts and analyzed 50 samples from 3 countries. No secondary cases were identified clinically.
Ebola virus is a highly lethal pathogen responsible for several outbreaks of hemorrhagic fever. Here we show that the primate lentiviral binding C-type lectins DC-SIGN and L-SIGN act as cofactors for cellular entry by Ebola virus. Furthermore, DC-SIGN on the surface of dendritic cells is able to function as a trans receptor, binding Ebola virus-pseudotyped lentiviral particles and transmitting ...
Over the past 30 years, Zaire and Sudan ebolaviruses have been responsible for large hemorrhagic fever (HF) outbreaks with case fatalities ranging from 53% to 90%, while a third species, Côte d'Ivoire ebolavirus, caused a single non-fatal HF case. In November 2007, HF cases were reported in Bundibugyo District, Western Uganda. Laboratory investigation of the initial 29 suspect-case blood specim...
Ebola and Marburg viruses are emerging/re-emerging pathogens that pose a significant threat to human health. These naturally occurring viral infections frequently cause a lethal hemorrhagic fever in humans and nonhuman primates. The disastrous consequences of infection with these viruses have been pursued as potential biological weapons. To date, there are no therapeutic options available for t...
BACKGROUND The transmission of hemorrhagic fever with renal syndrome (HFRS) is influenced by environmental determinants. This study aimed to explore the association between atmospheric moisture variability and the transmission of hemorrhagic fever with renal syndrome (HFRS) for the period of 1991-2010 in Changsha, China. METHODS AND FINDINGS Wavelet analyses were performed by using monthly re...
