ABSTRACT
In African countries Ebola virus has been responsible for several deaths. In addition to being a global health concern, the virus is also considered a potential biological threat. Ebola viruses are incompletely understood pathogens that cause severe, often fatal, illnesses in humans and non-human primates. Ebola virus disease affects most...

Ebola virus (EBOV) is a filovirus that can cause Ebola virus disease (EVD). No approved vaccines or therapies exist for filovirus infections, despite an urgent need. The development and testing of effective countermeasures against EBOV requires use of animal models and a thorough understanding of how the model aligns with EVD in humans. The majorit...
The identification of an Ebola virus case must take into account both the clinical manifestations as well as the travel history and exposure history reported by the patient among other variables. In line with this, this presentation aimed at:
1. illuminating the concept of contact tracing in the context of epidemiology and disease surveillance as...
Ebola virus (EBOV) caused more than 11,000 deaths during the 2013-2016 epidemic in West Africa without approved vaccines or immunotherapeutics. Despite its high lethality in some individuals, EBOV infection can produce little to no symptoms in others. A better understanding of the immune responses in individuals who experienced minimally symptomati...
Background The prevalence of Ebola virus infection among people who have been in contact with patients with Ebola virus disease remains unclear, but is essential to understand the dynamics of transmission. This study aimed to identify risk factors for seropositivity and to estimate the prevalence of Ebola virus infection in unvaccinated contact per...
In March 2014, the World Health Organization declared an outbreak of Ebola virus disease in Guinea. In August 2014, a case caused by virus imported from Guinea occurred in Senegal, most likely resulting from nonsecure funerals and travel. Preparedness and surveillance in Senegal probably prevented secondary cases.

... Many ZIKV cases most likely have gone unreported due to initial less reporting, high proportion of asymptomatic cases (>80%), and diagnostic challenges [27]. Similarly in 2014, Ebola virus has caused innumerable deaths in Central and West African regions especially in Guinea, Liberia, Nigeria and Sierra Leone [28]. ...
Pathogens in hostile terms can be defined as invaders that attack host organisms. Pathogens show different types of specificity or tropism. While many can attack a wide range of hosts, others are specific to one host. A human body is a preferable host for a wide variety of pathogens as it provides nutrient rich, warm and moist environment. Moreover the uniform temperature of the human body, allows the pathogen to survive and multiply itself, making it a desirable place. Emerging Infectious diseases by various pathogens had always been a matter of concern in the past and also at present. Despite the tremendous advancement in the diagnosis, treatment and prevention procedures, these infectious diseases still remain the leading cause of death around the world especially in developing countries. In this review, we made an attempt to discuss about some of the human pathogens like Human papillomavirus, Helicobacter pylori, Hepatitis, Mycobacterium tuberculosis and Plasmodium vivax, which are listed among the lethal microorganisms that frequently infect humans.
In this paper, silver nanopartical has been prepared by a simple chemical technique for use as antibacterial causes (Staphylococus epidermidis, Staphylococcus aureus, Klebsiella Sp., Candida albicans and Escherichia Coli.). The created nanoparticles were characterized by different techniques alike XRD, FTIR. The effects of the structure exhibited that the silver nanppartical had grain size ranging from (12.33-16.75) nm.
