Factors and causes of HIV

The HIV infection is caused by a subgroup of retrovirus that is known as the human immunodeficiency virus. Depending on the HIV type and also if it is not treated after It is discovered then the person can have a life span of nine to eleven years. The HIV can occur due to many reasons such as transfer of blood, pre ejaculate, semen, vaginally fluids or breastfeeding milk. The HIV bacteria are present in within these body fluids as free virus particles or even as virus that are within infected immune cells.

Classification of HIV species

HIV is a part of the Genus Lent virus which has several morphologies and biological properties that are common. There are two types of HIV species. One is the HIV 1 which has high virulence. It has also got high infectivity. The HIV 1 species have global prevalence and the inferred origin of this is common chimpanzee. But the good is that that now HIV can be treated in various clinics like that of HIV PEP clinic in Singapore.

Then there is the HIV 2 species whose inferred origin is sooty mangabey. It has got low virulence and the infectivity power of this type is also low. HIV 2 has got prevalence in West Africa.

The spread of HIV within the body

HIV causes the spread between CD4+ T cells. This spread generally occurs by two parallel routes. One route is the cell free spread and the other is the cell to cell spread. The virus particles in case of the cell free spread that are budding from an infected T cell can enter the body fluid and after that it can infection t another T cell. HIV is also spread through one cell to another by direct transmission. This process is known as the cell to cell spread. There has been a report of cell to cell transmission of HIV virus.

An antigen presenting cell that is abbreviated as APC is also capable of transmitting HIV virus to T cells. This is done by a process which involves productive infection or capture and transfer of visions in Trans.

In spite of the path that is used the infection that is spread by cell to cell transfer is much more efficient than the spread by cell free virus. There are certain factors that are responsible for responsible for increase in efficiency of these of this. These factors are polarized virus that buds toward the location of the cell to cell contact that is close apposition of cells that are responsible for minimizing the fluid phase diffusion of virions. They also reduce the clustering of the HIV entry receptors on the target cells to the contact area. In case of lymphoid tissue the cell to cell spread is much more important as there are the CD4 + T lymphocytes that are densely packed and they are more likely to interact frequently.

Symptoms of HIV

The symptoms of HIV infection are quite similar to that of fever, sore throat and fatigue. HIV is a disease that is asymptomatic until and unless it reaches the stage of AIDS. The symptoms of aids include weight loss, fever and also night sweats. It also includes fatigue and recurrent indirection.

Other symptoms include pain in certain areas like in the abdomen. While swallowing a HIV infected person can suffer pain. They are also subjected to dry cough. They have gastrointestinal problem that include nausea, persistent diarrhea, vomiting and also watery diarrhea. HIV virus can even cause problem in the mouth such as ulcers and white tongue. It may also cause problem in your groin and it may cause it to swell. It also causes problem in your throat such as sore throat problem and swelling.

There are certain common infection that includes opportunistic infection, head ache, oral thrush, pneumonia, Red blotches, severe unintentional weight loss, skin rash and swollen lymph nodes.

Treatment for HIV

There is no such particular treatment for Aids but with strict adherence to antiretroviral regiments one can very much slow down the process of the disease and they can even prevent the secondary infection and the complications that may arise.

Medication support

HIV antiviral – This drug helps to slow the process of the infection that is caused by HIV. This also reduces the chance of infecting other people. To know about how to get more medical support on this HIV disease you can check this page http://hivsingapore.com/

Infectious disease doctor

They treat the patients who have this disease and it also includes the patients who have the disease that is tropical in nature.

Clinical psychologist

Then there are these clinical psychologists that can cure the mental disorders mainly by means of talk therapy.

Primary care provider

The primary care provider or PCP can also help in preventing the disease through diagnoses and treatments.
