HIV disrupts homeostasis in the host by targeting and destroying CD4+ T cells, which are crucial for the immune system's ability to regulate and mount responses to infections. This depletion weakens the immune system, leading to opportunistic infections and diseases that the body would typically control. Additionally, HIV can cause chronic inflammation and dysregulation of various immune responses, further destabilizing the body's internal balance and contributing to systemic health issues. Overall, HIV's impact on immune function creates a cascade of effects that compromise homeostasis.

Why HIV is so hard to treat?
HIV has devised clever strategies that allow it to persist for many years in an infected person. HIV splices its genes into those of the host, so it is intimately associated with a variety of cells. The virus hides in certain reservoirs in the body that are not easily reached by current drugs. Moreover, as HIV spreads in an infected individual, it undergoes changes. Thus, many variants of HIV can exist even within a single person. This variation allows HIV to escape from the patient's immune system or from some antiviral drugs. We're not treating one virus, but many thousands of slightly different viruses, each tenaciously integrated into host cells. A realistic goal for the treatment of HIV-infected individuals is not to totally rid the body of HIV, but to suppress it so that it does not cause disease and is not efficiently transmitted to anyone else.
What is it called when infection leads quickly to breaking open of host cell?
HIV
What genetic material of some viruses such as HIV is not normal DNA but is instead?
Some viruses, such as HIV, contain RNA as their genetic material instead of the more typical DNA. Specifically, HIV is a retrovirus, meaning it uses reverse transcription to convert its RNA into DNA after entering a host cell. This DNA then integrates into the host's genome, allowing the virus to replicate and persist within the host.
What does HIV use to reproduce?
HIV is a retrovirus as it transcribed mRNA into DNA. It invades a host cell and uses the cells machinery to copy its own genetic material. This produces multiple copies of the virus within the host cell, which then ruptures releasing the virus and the process is repeated.
How is HIV different from other virus pathogens?
HIV targets the immune system's CD4 cells, which are crucial for fighting off infections, leading to a weakened immune system over time. Additionally, HIV can integrate its genetic material into the host cell's DNA, making it difficult to eradicate from the body. These characteristics make HIV unique compared to other viruses.
How is HIV transmitted from host to host?
By exchange of body fluids.
Can someone be a host for the HIV virus and not have HIV?
Definitely the answer to this is an emphatic NO. If you have HIV then you are a host for HIV and vice versa. You cannot be one without the other.
Can the HIV virus live outside the human body in fluids if not smeared?
Yes, infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate or breast milk.
What is a form in which HIV hides in the host cell?
the forms in which hiv hides in the host cell is retrovirus
How does HIV disrupt the functions of the body?
HIV stands for Human Immune-deficiency Virus. It affects the body by making your immune system less efficient than normal, and so you are more vulnerable if a disease comes along. HIV is the cause for AIDS. AIDS stands for Acute Immune-deficiency Syndrome, which is more affecting than HIV.
How does hiv affect the body and disrupt its homeostasis?
HIV prevents the body from maintaining homeostasis by disrupting the body's ability to fight disease. When a person's immune system is healthy and functioning, it is able to ward off many pathogens, virtually unnoticed. Our skin, saliva, tears, mucous membranes, all parts of the immune system, are effective barriers against many bacteria, virus and other microorganisms. However, when the immune system is damaged in some way, in this case by the HIV virus, that balance between pathogens in the environment and our ability to fight them off effectively, is destroyed. Ultimately, the body's immune system is depleted. Disease sets in. The body can no longer fight disease off, and the person begins a decline that will eventually result in death.
Can aids virus survive under outside temperature?
No. HIV needs a host. It does not live long, outside the body.
When can a person get the hiv virus?
HIV is only transmitted by five bodily fluids: blood, semen, preseminal fluid, vaginal fluid, and breast milk. Any of those fluids from an infected host getting into the body of another person can transmit HIV. No other fluids (saliva, urine, etc.) from the body transmit HIV.
What year did arsenio hall get hiv?
As of June 2014, Arsenio Hall does not have HIV or AIDS.
What is the role of integrase in HIV?
The role integrase plays in HIV is that it fuses viral DNA with host DNA.
Is a person with HIV antibodies a host of HIV?
If you have HIV antibodies then you are infected with HIV. The only exception to this is if you are a newborn. Newborns carry mothers IgG antibodies to HIV and the half life of IgG is approximately 21 days.
What two ways does HIV avoid the host's antibodies?
Gvu
