Hantavirus Hantavirus is a virus in the Bunyaviridae family of viruses. Dr. Lee Ho Wang from Korea discovered Hantavirus in the early 1950s. Though the virus is commonly found in rodents, it does not cause disease in the rodents. Disease results when the virus is transmitted to humans. A common way of contracting Hantavirus is from breathing in dust that has been contaminated by an infected rodent’s saliva, feces or urine or the infected dust gets into broken skin. It is also transmitted by the

As terrorists groups become better financed and more sophisticated, the opportunity for terrorism in the United States and Europe becomes much greater. Within the sphere of bio-terrorism, there are a variety of agents for terrorist groups to utilize, ranging from Category A, B, and C bioweapon agents. The whole board of biological weapon agents highlights the goal that terrorists have in common: to attack our core human biology and kindle the growing panic within each of us. Introduction Parallel
1. 8. Dengue Virus The causative agent of the dengue disease is the dengue virus (DENV), a group of four flaviviruses that are closely related but antigenically distinct. They are hypothesised to have evolved independently from ancestral sylvatic viruses between 100-1,500 years ago (Wang et al., 2000). The four groups are known as serotypes and denoted as dengue virus type 1 (DENV-1), dengue virus type 2 (DENV-2), dengue virus type 3 (DENV-3) and dengue virus type 4 (DENV-4). 1. 8. 1.
