The virology involves the study of viruses, their ecology, classification and structure.  Those who choose this field of work are referred to as virologists.
Virologists study, research, and sometimes are vaccines for viruses. Virologists may have different levels. The levels 0-4 are levels without one. These levels measure the harmfulness of viruses that virologists working. Virologists 0 level deal with viruses, like the common cold. Level 3 involves viruses like AIDS. Level 4 deals with the most dangerous viruses. These include Marhburg, Ebola and Hanta. Viruses level 4 require more protection. Virologists who deal with these types of viruses must wear garments of biosecurity. There are only two units of level 4 within the U.S., which has the ability to study these types of viruses. The Centers for Disease Control and Prevention (CDC) in Atlanta and The United States Army Medical Research Institute for Infectious Diseases (USAMRIID), which has its facilities in Maryland.
Virologists can work at various sites. These locations can vary from a rainforest in Africa, to a local hospital, and even a four-level laboratory. Virologists may even help develop vaccines, while working for pharmaceutical companies.
Despite attempts to understand the growth of viruses in cells occupying most of the efforts in recent years virologists viruses are still one of the major causes of human diseases. 
To become a virologist need to go to school for several years. The amount of years depends on the field of virology. Virologists are studying various areas of science. These include epidemiology, microbiology, chemistry, molecular biology and virology.
The salary varies virologists. Factors affecting earnings include, but not be limited to: the level of biological risk, the survey, travel required, and the employer. The salary can range from about $ 30, 000 to over $ 100, 000 per year in the United States. 
A variety of procedures has been developed for the cultivation of viruses. In most cases, it is necessary to supply the virus with appropriate cells in which it can replicate. In some cases it is possible for the cultivation of viruses systems without the presence of cells.  In animal viruses, the culture system for the growth of a virus is constituted by living cells remains the choice between the three systems culture: live animals in an organ culture (for example, pieces of brain) or in cell cultures. The latter are divided into three types of cell cultures: Primary cells, cell lines and permanent cell lines.  Before the advent of cell culture, many viruses were propagated in embryonated chicken eggs. 
The virus can be isolated from an infected host crop material excreted by or secreted, and testing blood or tissue to induce the same symptoms in a host identical or by induction of some abnormal condition in a surrogate host or in cell culture.

Chemical agents usually fall under specific categories--vesicants (blistering agents, like mustard gas), nerve agents (like sarin), pulmonary agents (like phosgene and chlorine), cyanide, and riot control agents (like mace and pepper spray--and make no mistake, those things can kill you). Non-weapon uses of all these compounds exist: nitrogen mustards are used in cancer chemotherapy, and nerve agents are popular insecticides. For this reason, treatments exists--especially for the nerve agents. (wedge, you probably were better equipped than you thought.) The Army manual that I am referencing (Medical Management of Chemical Casualties, 2nd ed, 9/95) does not mention defoliant agents like dioxin (a component of Agent Orange), but there's no treatment for that, anyway
