There is currently no vaccine or cure for AIDS or HIV. The only known method is avoiding exposure of the virus. However a treatment known as post-exposure prophylaxis is believed to reduce the risk of infection if begun directly after exposure. Current treatment of HIV infection consists of highly active anti-retroviral therapy (HAART). This refers to combined therapy with three or more drugs, usually two that target the reverse transcriptase and one that targets the viral protease. Kimball's biology pages. 7 Oct. 2004. 24 Feb. 2007
Natural resistance to HIV can be considered at two levels: resistance to becoming infected with the virus and resistance to the virus if the person is already infected. The mechanisms of natural resistance in both cases are:
Apoptosis. Apoptosis is a programmed death of the cells in multi-cells organism. During the HIV infection apoptosis is the main mechanism by which infected and uninfected CD4+ lymphocytes are eliminated. However apoptosis as a natural resistant mechanism to HIV infection has not been explored so far.
Natural resistance is the mechanism by which an organism protects itself from infection by identifying and killing pathogens. It does so by using several types of proteins, cells, organs and tissues which interact in an elaborate and dynamic network.
Human immunodeficiency virus (HIV) is a retrovirus that causes Acquired Immunodeficiency Syndrome (AIDS), a condition in which the immune system begins to fail, leading to infections…
While some of these inhabit hot temperature places, others would only survive in ice cold conditions; while others survive with oxygen, others do not need oxygen for survival.

The rapid spread of HIV/AIDS pandemic in Africa is a major threat to its development since it has ravaged across the productive workforce and the expenditure by the governments in the fight against the pandemic is unbelievably high. It can be noted that the effects of HIV/AIDS pandemic have a direct bearing on the development of the African countries.
Virus diseases inflict a heavy illness and economic damage on humans and animals and can injure agricultural crops. Each viral particle, called virion, consists of genetic material, DNA or RNA, within a protective protein coat called a capsid. Their shape varies from simple helical and icosahedral (polyhedral or near-spherical) forms, to more complex structures with tails or an envelope.
The WHO has estimated about 420,000 new MCT infections in children in the year 2007 (WHO, 2008). This mode of transmission of HIV infection is almost preventable (WHO, 2008).
This is the best method of prevention of infection in the child and is 100% effective.
t in other areas, Africa urgently needs the rich nations to deliver on their promises to reverse the severe effects of poverty and the HIV/Aids pandemic. The rapid spread of HIV/AIDS pandemic in Africa is a major threat to its development since it has ravaged across the
The originality of this research article is quite commendable, and stands above average. This study is the first to be conducted in the National Hospital in Abuja, Nigeria. Previously, evidence that HBV/HIV and HCV/HIV co-infection prevalence was at an increase,
The author states that in the United Kingdom, sexually transmitted infections are a public health concern especially among young sexually active persons particularly those aged between 15 and 25 years.
