The common features of viral biothreat agents are highly lethal, easy to grow, and transmissible by aerosol. The examples of viral diseases caused by these agents are smallpox, viral hemorrhagic fevers, and viral encephalitis together with newly emerged viral diseases such as severe acute respiratory syndrome (SARS) and avian influenza. A deliberate release of these agents on general public or ...
Zoonotic transmission of novel viruses represents a significant threat to global public health and is fueled by globalization, the loss of natural habitats, and exposure to new hosts. For oronaviruses (CoVs), broad diversity exists within bat populations and uniquely positions them to seed future emergence events. In this review, we explore the host and viral dynamics that shape these CoV popul...
Background: The risk of hepatitis C virus (HCV) transmission during assisted reproductive techniques (ARTs) is still disputed and no report concerning its prospective evaluation is available. The aim of this 4-year follow-up multicentre study that enrolled 86 HCV-serodiscordant couples was to determine whether a sperm-processing method was able to reduce levels of HCV in semen and the risk of H...
Background and Aims: The emergence of drug-resistant influenza viruses has become a serious threat for human and animal populations. Glycyrrhiza glabra (Gg) is a traditional medicine clinically used for the treatment of viral respiratory infection symptoms in most countries. We evaluated the effects of the herb on influenza virus replication in human lung cultured cells (A549) following the det...
During the past decade several new viruses have emerged making a global health threat. The most pandemic threats are due to the either zoonotic or vector-borne viruses. The emerging of new infectious diseases continue to be threaten of public health and the social activities including traveling or trade help to sustain and spread of the viruses. Developing methods to manage and predict th...
The viral hemorrhagic fever viruses represent a unique group of viruses that can produce large outbreaks of both animal and human disease and produce severe, highly fatal, human illnesses. The viral hemorrhagic fever viruses display a great deal of diversity in their genetic organization, vectors for transmission, and geographic distribution. They share common features in being able to induce a...
