Question

why does AIDS patient suffer from many other infections ? name any two such organisms which AIDS patient gets affected with

Answer 1

AIDS is caused by a HIV virus.Human immunodeficiency virus (HIV) is a retrovirus which infects human beings causing AIDS. AIDS is a disease in which the immune system of the individual gets affected and immunity is reduced. Lymphocytes present in the blood are destroyed by HIV. This makes the infected individuals more vulnerable to other fatal diseases and infections. Hence, infected person's body is not able to fight even minor infections like cold and minor infections can be fatal in this disease.

HIV is classified into 3 stages: acute HIV, chronic HIV, and AIDS.
HIV doesn’t always multiply rapidly. If left untreated, it can take years for a person’s immune system to be affected enough to show signs of immune dysfunction and other infections. View a timeline of HIV symptoms.
Even without symptoms, HIV can still be present in the body and can still be transmitted. Receiving adequate treatment that results in viral suppression stops the progression of immune dysfunction and AIDS. Adequate treatment also helps a damaged immune system to recover.

Once a person contracts HIV, the acute infection takes place immediately.
Symptoms of the acute infection may take place days to weeks after the virus has been contracted. During this time, the virus is multiplying rapidly in the body, unchecked.
This initial HIV stage can result in flu-like symptoms. Examples of these symptoms include:

.fever
.headache
.rash
.swollen lymph nodes
.fatigue
.myalgias, or muscle pain

However, not all people with HIV experience initial flu-like symptoms.
The flu symptoms are due to the increase of copies of HIV and widespread infection in the body. During this time, the amount of CD4 cells starts to fall very quickly. The immune system then kicks in, causing CD4 levels to rise once again. However, the CD4 levels may not return to their pre-HIV height.
In addition to potentially causing symptoms, the acute stage is when people with HIV have the greatest chance of transmitting the virus to others. This is because HIV levels are very high at this time. The acute stage typically lasts between several weeks and months.
