Let s conclude this discussion of life with a short consideration of viruses. Viruses cause all sorts of problems for living organisms. The problems are the consequence of their ability to infect, and ultimately kiU, many types of cells— bacterial, animal, and plant—though each virus is quite specific in terms of the type of cell that it infects. There are many types of viruses. In people, they cause measles, mumps, influenza, AIDS, polio, potentially fatal diarrhea in infants and very young children, herpes, chicken pox, shingles, the common cold, and many other diseases, that may be fatal, serious, and not so serious. In other animals, viruses also cause any number of diseases, as they do in plants. Much effort has been, and continues to be, devoted to the prevention, diagnosis, and treatment of viral diseases. 

A wide variety of organotin compounds developed by Carraher, Sabir, Roner, and others based on known antiviral drugs such as acyclovir and known antibacterial agents such as ciprofloxacin, norfloxacin, cephalexin (structure 11.21), and ampicillin inhibit a wide variety of viruses including ones responsible for many of the common colds, chicken pox, small pox, shingles, and herpes simplex. 

WraZ/nfecf/on. Treatment with tacrolimus ointment may be associated with an increased risk of varicella zoster virus infection (chicken pox or shingles), herpes simplex virus infection, or eczema herpeticum. 

The word vaccination comes from vaccinia, the name of the virus now known to cause cowpox vaca is the Latin word for cow ). The term vaccination is now broadly used to describe the process of causing a mild disease in order to protect a person from a more dangerous disease. Vaccination is one form of immunization, exposing the body to a material to stimulate a protective response from the immune system. Vaccination is routinely used to prevent many illnesses, including measles, rnmnps, German measles (rubella), chicken pox, and polio. Many of these illnesses have disappeared or become very rare in developed countries that provide widespread vaccinations. Smallpox has been eradicated worldwide, thanks to...

Aspirin is epidemiologically associated with Reye s syndrome, a rare but often fatal consequence of infection with varicella, influenza and various other viruses, and salicylates are therefore contraindicated in children with chicken pox or influenza. 

Active immunity occurs when the organism is exposed to a toxin or infectious agent (bacterium, virus, or parasite) so that the immune system is stimulated. Most of your parents, grandparents, and instructors contracted measles, mumps and chicken pox when they were children and so are now naturally immune to such agents because their antigenic memory (B and T cells) is primed for a full scale IgG response. 

Herpes describes a family of viruses. In general, the term herpes is most closely associated with the conditions of oral and genital herpes, which are caused by the herpes simplex viruses (HSV). Other frequently encountered herpes viruses include the Epstein-Barr virus (EBV, which causes mononucleosis), cytomegalovirus (CMV, which causes various infections of the eyes, liver, colon, and lungs), and varicella zoster virus (VZV, which causes chicken pox and shingles). 

Biohazard level 1. Bacillus subtilis, canine hepatitis, E. coli, varicella (chicken pox). At this level precautions against the biohazardous materials in question are minimal, most likely wearing gloves and some facial protection. Decontamination procedures at this level are similar in most respects to modern precautions against everyday viruses (washing hands with antibacterial soap, washing all exposed surfaces of the lab with disinfectants, etc.). 

Jenner s speckled monster (smallpox) has been defeated, but AIDS will be with us for many years to come. While smallpox was eradicated by means of a worldwide vaccination campaign, prevention of acquired immune deficiency syndrome or AIDS will require new drugs and more careful sexual behaviour. Both diseases do share a common feature - they are caused by Nature s most successful parasites - the viruses. In the developed world, it is not uncommon for a person to survive to a ripe old age without experiencing a serious bacterial infection or contracting one of the many forms of cancer. They will, however, have suffered from the effects of numerous viral infections of the respiratory tract, i.e., colds and flu, and most probably, from the common childhood virus-inflicted disease of chicken pox. It is unlikely that any of these afflictions will have been life-threatening, but they will have caused many days to be lost from school or work. In other words, the morbidity due to the common viral diseases is high, but the mortality is low. 

The symptoms of infection by varicella zoster are usually unmistakable the slight fever accompanied by a rash, which tends to be concentrated on the central part of the body (the trunk) rather than on the face, arms and legs. The spots (vesicles) resemble drops of water on the skin, and these soon dry to form scabs. The infected child is inconvenienced rather than incapacitated by the infection. In adults, chicken pox can have very serious consequences, and may lead to potentially life-threatening encephalitis or pneumonia. However, the more common form of varicella zoster infection in adults leads to a condition known as shingles. This is manifested as severe inflammation of the sensory nerves, which is usually accompanied by intense pain, and later by a rash. In most instances, it seems that the varicella zoster virus of infancy has lain dormant for many decades in the nerve cells, and has been reactivated in response to some kind of trauma (perhaps depresssion or an infection), to produce an attack of shingles. 

Chicken pox is a highly contagious viral infection that causes rash-like blisters on the skin surface and mucous membranes. It is generally mild and not normally life-threatening. For adults, the symptoms are more serious and uncomfortable than for children. The disease can also be deadly for some people, such as pregnant women, people with leukemia, or immunosuppressed patients. Varivax (varicella virus vaccine live) from Merck Co. was tested on about 11 000 children and adults, and was approved by the FDA in March 1995 as a chicken pox vaccine. 

Viruses are infectious, parasitic small particles containing either DNA or RNA (but not both) encapsulated by a protein overcoat. Viruses are at the borderline of life since they neither reproduce nor carry out metabolism. Viruses are unable to reproduce or synthesize proteins because they lack some or most of the apparatus (amino acids, nucleotides, and enzymes) for replication, transcription, and translation. Viruses are responsible for a wide range of diseases—influenza, poliomyelitis, leukemia, hepatitis, smallpox, chicken pox, tumors (including cancer), and AIDS (acquired immune deficiency syndrome).
