Viremia (Viraemid)

Viremia is the presence of viruses in the blood and can be caused by various reasons such as infections, vaccinations, organ transplants and other medical procedures. Viremia can be dangerous to human health, as viruses can penetrate cells and cause various diseases such as influenza, hepatitis, HIV and others.

Viremia can manifest itself with various symptoms, such as fever, cough, weakness, muscle and joint pain, headache, nausea and vomiting. Changes in blood tests may also be observed, such as an increase in the number of white blood cells, a decrease in platelet levels, and others.

To diagnose viremia, various methods are used, such as a blood test for antibodies to viruses, PCR analysis, enzyme immunoassay and others. Treatment for viremia depends on the type of virus and its severity. In some cases, hospitalization and intensive care may be required.

Prevention of viremia involves following the rules of hygiene, vaccination, avoiding contact with sick people and using personal protective equipment. It is also important to monitor your health and consult a doctor if symptoms of the disease appear.

Viremia (virosphere) is the presence of various types of viruses and other pathogens in the human or animal body and their effect on the body. This term is used mainly in virology and microbiology. The concept of “viremia” reflects the existence of biological objects at a different level of organismal organization, different from viruses, the so-called viroids. The basis for isolating viroidis is their much higher resistance to various physical, chemical and biological influences, as well as to the action of the specific immune system of the macroorganism (compared to viruses).

The word “viremia” is used in the plural, although almost all viruses have a specific individual RNA, characteristic only of this virus, and the presence of another separate viral population has not yet been proven. However, the general properties of viruses always lead to the formation of an easily recognizable group of genotypes using genetic methods; such groups are usually called nodus or synonyms of viremia of a given class of viruses or by their characteristics at some level of structural organization - virion or antigen. Some viruses have from several to several dozen genotypes, all of which are determined to be viraemic by analyzing and comparing their antigenic structure. Being in viremia all its life, the virus is in lifelong interaction with the macroorganism, which regulates the state of its viremia and optimizes the state of the virus genome (phenotype). Effective reproduction of the virus disrupts the normal vital processes of the macroorganism and suppresses immune defense factors, which leads to the occurrence and development of the disease. Viruses are important in the development of pathology in humans and animals; they are objects of their fight and neutralization by immune mechanisms, which, as a rule, is accompanied by an adequate response of the macroorganism. Therefore, the study of viremia and viruses plays an important role in many areas of biology,
