What Is Acute Retroviral Syndrome?

Retrovirus is a type of virus that refers to human disease. Virological genetic information is not stored in DNA, but in RNA.

The more well-known retroviruses include HIV.

Most of the diseases caused by retroviruses are relatively chronic. Although some viruses do not directly cause the disease, they can cause cancer, and some viruses can be inserted into the genes of cells without causing disease. In the course of human evolution, many retroviruses inserted their genes into human genes and became part of human genes.

There are three types of retroviruses:

1. Oncogenic viruses can cause cancers such as leukemia. They contain oncogenes. 35 types of oncogenic viruses have been found that can cause malignant diseases in birds and mice. In humans, there is currently only type 1 human T-cell leukemia virus (HTLV-1), which can cause adult acute T cells. Lymphocytic leukemia (ATLL), a virus that can be transmitted through blood transfusion, sexual activity, or breastfeeding, is endemic in southern Japan. About one out of every 20 infected people will get sick, with an average of 30-50 years after infection. In addition to the increase in white blood cells, skin performance is also characterized. Its cells have polymorphic and leafy nuclei, known as floral cells.
2. Lentivirus can cause chronic diseases such as AIDS.
3. The foam virus does not cause disease.

When infecting a victim cell, the retrovirus first reverse transcribes its RNA into DNA (hence the name retrovirus), and then inserts this reverse transcribed gene into the cell's gene, which is transformed by the cell's transcriptional mechanism into a viral protein And RNA. Retroviruses usually have a layer of fat outside their shell.
