Answer:
HIV
Step-by-step explanation:
HIV is a retrovirus, is an enveloped virus classified in the Lentiviridae subfamily and is a sexually transmitted infection. This virus infects a host cell by attacking the immune system, which is responsible for defending the body from disease. The most affected cells are CD4 + T lymphocytes. The virus is capable of altering the DNA of this cell and making copies of itself. After multiplying, it breaks the lymphocytes in search of others to continue the infection.
