 Viral disease   (Site not responding. Last check: 2007-10-30)
The envelope, normally derived from thecell membrane of the previous host, protects the viral genome contained within and alsoprovides the mechanism by which the virus infects its host.
The most effective medical approaches to viral diseases, thus far, are vaccination to provide resistance to infection, and drugs that treat the symptoms of viral infections.
Patientsoften ask for antibiotics, which are useless against viruses, and theirmisuse against viral infections is one of the causes of antibiotic resistance in bacteria.

 Viral classifications   (Site not responding. Last check: 2007-10-30)
Viruses can be classified in several ways, such as by theirgeometry, by whether they have envelopes, by the identity of the host organism they can infect, by mode of transmission, or bythe type of disease they cause.
The most useful classification is probably by the type of nucleic acid the virus contains and itsmode of expression.
Viruses in classes I and II in the following classification are considered to be DNA viruses, all others are considered to be RNA viruses.

 What is the Viral Load ?
Your viral load is the amount of viruses present in a given volume of your blood (usually 1 millilitre = 1 cubic centimeter).
Ideally, HCV RNA viral load should be estimated directly from liver tissue itself, because serum levels of virus may be contributed to and influenced by extrahepatic sources.
The authors conclude that intrahepatic viral load appears to be significantly increased in patients with genotype 1b, but their results do not support the hypothesis that increased intrahepatic HCV load is associated with more severe liver injury.

 Belgian Classifications for Micro-organisms
The class of risk given to a wild biological species must be regarded as representative of the theoretical maximum risk incurred by the man, the animal, the plant or the environment.
The classification of a of micro-organism takes into account the risk for health, for the community, and - in the case of the animal and the plant - the possible economic impact of the disease.
When the pathogenicity of a viral, bacterial, fungal or parasitic strain is attenuated (by spontaneous emergence, selection or because of the use of the techniques), the user can justify a reduction of the biological class of risk of this strain compared to the class of risk assigned to the parent strain.

 Information Headquarters: Virus
Viral structure Viruses typically consist of a protein coat (the envelope), a protein core (the capsid) that encloses the viral genes and the viral genetic material itself.
Human viral diseases Examples of diseases caused by viruses include the common cold, which is caused by a variety of related viruses; smallpox; AIDS, which is caused by HIV; and cold sores, which are caused by herpes simplex.
Prevention and treatment of viral diseases Because they use the machinery of their host cells, viruses are difficult to kill.

 SF AIDS Fdn: BETA 12/96 -- AIDS Dementia Complex
It has been reported that reductions in viral load as measured by polymerase chain reaction (PCR) and branched-chain DNA (bDNA) assays have led to decreases in the incidence of new opportunistic infections (OI) and in the total number of AIDS-related hospitalizations among individuals who use powerful combinations of antiretroviral drugs.
The endothelial cells that line the capillaries of the brain are tightly linked to form a blood-brain barrier, which is selectively permeable to substances in the blood.
(Viral load in the CSF and in the brain may differ.) Price and Staprans feel that they are now in a position to learn much about the natural history of ADC, about prevention and treatment and about the rate at which resistance to protease inhibitors develops in the brain and CSF.

The most common is the Rappaport classification and the Working formulation by the National Cancer Institute.
The working classification is a compromise between the histologic pattern and prognosis.
Molecular studies are also useful in the determination of B- or T-cell lineage, in the detection of chromosomal translocations, detection of minimal residual disease, and in the detection of viral DNA sequences (eg, those of the Epstein-Barr virus) involved in the pathogenesis of some lymphomas (Cossman, 1988; Cossman, 1990).
