What is the phases of HIV infection?

Answer 1

People who are at the end stage of HIV are classified as having AIDS. They will have high viral loads, low CD4+ counts, develop conditions such as Kaposi's sarcoma, thrush, PCP and other opportunistic infections. Typically, it is the infections that causes death.

Answer 2

Up to 70% of people newly infected with HIV will experience some "flu-like" symptoms during this stage. These symptoms, which usually last no more than several days, might include fevers, chills, night sweats, and rashes. Afterward, the infected person returns to feeling and looking completely well. The remaining percentage of people either do not experience symptoms of acute infection or have symptoms so mild that they may not notice them.

Given the general character of these symptoms, they can easily have causes other than HIV, such as a flu infection. For example, if you had some risk for HIV infection a few days ago and are now experiencing flu-like symptoms, it is possible that HIV is responsible for the symptoms, but it is also possible that you have some other viral infection instead. If you believe you may have been exposed to HIV, you may want to consider calling an AIDS hotline to discuss whether you were in a situation that put you at risk for HIV infection and whether you should take an HIV test. Call the CDC National AIDS Hotline toll-free at 800/342-AIDS.

Answer 3

HIV will mimic a cold-like experience,including fever,fatigue,headaches and sometimes a rash
There are a number potential early symptoms for HIV. Some of the most common symptoms include fatigue, fever, aching muscles and joints, headaches and skin rash.
There are no outward signs or symptoms that are reliable indicators of HIV infection. HIV (Human Immunodeficiency Virus) attacks the cells in the body that fight disease. A person cannot feel the effects of the virus and may not exhibit symptoms of infection for many years. If a person is concerned they may have been exposed to HIV, they should be tested 90 days after their last potential exposure to the virus.

Answer 4

Phase 1: Window Phase.

This is just after infection, where the virus is beginning to multiply within the body, but there is no physical signs of the disease. An HIV test at this point would come back as negative but the person is still able to infect other people even at this stage. This lasts roughly three months.

Phase 2: Seroconversion.

This is where enough antibodies have been built up in the body for an HIV test to come back positive. A person may suffer from mild, flu-like symptoms which will clear up after a week or two.

Phase 3: Asymptomatic period.

This is the time where absolutely no physical sign of the illness can be seen. The infected person will seem absolutely healthy, while inside the HIV virus multiplies, decreasing the CD4 count. This can last between 1 to 15 years.

Phase 4: HIV related illnesses. At this stage the body will begin to succum easily to illnesses such as fungal infections, sores, flu etc. Lasts around 5 years.

Phase 5: AIDS. At this stage the virus has all but destroyed the immune system and any virus can attack the body. Without antiretrovial drugs the infected person would last, at most, two years. With the help of these drugs the virus can be suppressed and the patient may live for many more years. The CD4 count is below 200.

Answer 5

Fever - 90 to 95% (Last up to 1 week)

Sore throat - 70 to 85% (Variable)

Muscle ache - 50 to 60%

Joint pain - Way lower compared to muscle ache

Lymph node - Usually swollen following fever and sore throat (Can last up to 3 weeks)

Symptoms usually manifest from week 1 to week 4. All of this occur during the acute phase.

Fever will usually be the first symptom appearing...not to mention rash might develop on the chest or back.

Hope this answers your question.

Answer 6

1. Viral attachment: Viral glycoprotein gp120 binds to host receptor.

2. Penetration: Reeptor-mediated endocytosis

3. Uncoating of the viral core (which contains the 2 ssRNA strands and the enzymes)

4. Replication: RT (and RNase H) produces DNA strand, then inserted to host genome via integrase

5. Assembly: Viral proteins (e.g. transmembrane protein gp41, capsid proteins that form the core) is produced

6. Released: Cell lysis - basically using the host cell membrane

Answer 7

1. Primary HIV Infection
2. Asymptomatic HIV
3. Symptomatic HIV
4. Acquired Immune Deficiency Syndrome

Answer 8

Primay , Asymptomatic , Symptomatic , then AIDS

Answer 9

AIDS is the immuno-deficiency syndrome a person exhibits due to the damage to the immune system caused by HIV. In other words, AIDS comes into play in the later stages of HIV.
