There Are Two Types Of Antiviral Infection

A Antiviral is a living organism that lives in a non-cellular form of a nucleic acid molecule (DNA or RNA) with a protein. The main features are: ① the body is extremely small, must be observed under the electron microscope; ② no cell structure, the main component is only nucleic acid and protein two; ③ a Antiviral contains only one nucleic acid (DNA or RNA) ④ in vivo No â ... â ... â ... â ... ⑤ with nucleic acid and protein and other "components" of the assembly to achieve its large number of breeding; ⑥ in vitro conditions, to the inanimate life of the enzyme can be used in the living cells of the existing metabolic system to synthesize their own nucleic acid and protein components; Biological macromolecules exist, and long-term to maintain its vitality; ⑦ is not sensitive to the general antibiotics, but sensitive to interferon; ⑧ some of the Antiviral nucleic acid can also be integrated into the host genome, and induced latent infection.

The general symptoms of viral infection are fever, headache, cough and other symptoms of systemic poisoning and viral host and invasion of tissues and organs leading to inflammatory symptoms caused by local symptoms (diarrhea, rash, liver function damage, etc.). According to the different symptoms of the Antiviral, some Antivirales can also damage the myocardium, causing viral myocarditis.

There are two types of viral infections, mostly recessive infections (subclinical infections), and a few are dominant infections. Dominant infection can be acute

Infection and persistent infection type:

Acute infection - acute onset, rapid progress, the course of the general for several days to several weeks. In addition to a small number of deaths in the acute phase and the occurrence of sequelae, the majority of cases eventually to tissues and organs of the Antiviral was cleared and cured.

Persistent infection - the Antiviral long-term presence in the host, up to several months to several years, resulting in chronic persistent infection, but also points the following three types: ① latent infection. When the Antiviral and the human body immunity in a relatively balanced state, the Antiviral can be lurking in human tissue for a long time, does not cause symptoms. Once the human body immunity is reduced, the Antiviral can reproduce and cause symptoms. Such as herpes simplex Antiviral, Epstein-Barr Antiviral and varicella-zoster Antiviral-induced latent infection. Chronic infection. Antiviral long-term presence in human tissues and organs, resulting in chronic persistent disease, such as hepatitis B Antiviral caused by chronic hepatitis B. ③ lentiAntiviral infection. Long incubation period, up to several years, the gradual development of the disease, and finally lead to death.
