While the primary focal point of this essay is the United Kingdom ( UK ) it is of import for the apprehension of HIV / AID to give a background on the planetary impact of this disease. HIV/AIDS is the universe ‘s taking infective slayer and its incidence is go oning to lift globally despite wellness publicities and attempts to increase consciousness ( 11 ) . More than 60 million people have been infected with HIV since the beginning of the epidemic and 25million mortality associated with HIV related causes, doing it one of the most destructive pandemics in recorded history ( 5 ) ( 27 ) . HIV and AIDS remains one of the universe ‘s most important public wellness challenges, peculiarly in developing states where medicines, health care and resources are really limited.
Diagnosis of HIV / AIDS began in the UK in late 1981 ( 9 ) . There is an addition in the figure of HIV instances in the UK, the rate of new diagnosings in HIV infections doubled from 2735 ( 1997 ) to 5542 ( 2002 ) . In 2008, there were 83,000 people populating with HIV in the UK, 27 % of these were undiagnosed ( unaware of their positive position, they were measured by unlinked anon. HIV study ) and merely 61, 213 were accessing HIV attention. The Unlinked anon. Prevalence Monitoring Programme ( UAPMP ) was introduced in the UK in 1990 to ease the prevalence of HIV infection. Blood samples are collected from GU medical specialty ( GUM ) clinic users, pregnant adult females and shooting drug users ( 12 ) . The programme is anon. hence all personal identifiers are removed from the blood sample. Although the programme gives the prevalence of HIV infection, it does n’t forestall the transmittal of HIV from the ‘positive unaware ‘ to clean people and besides it leaves the challenge of acquiring this group tested so that they can go cognizant of their HIV position and have appropriate intervention ( 11 ) .

When the trials for HIV antibodies became widely available in the mid 1980s, three chief hazard groups of HIV were identified. These were work forces who have sex with work forces, shooting drug users and people who have received intervention with blood merchandises. Many of these people came frontward for proving in the mid 1980s, after which there was a diminution in the one-year figure of HIV diagnosings. This tendency was reversed towards the terminal of the decennary and there were between 2,500 and 2,800 diagnosings each twelvemonth from 1990 to 1997.
Between 1999 and 2003 there was a steep addition in the figure of HIV diagnosings. A extremum of 7,975 new diagnosings was observed in 2005. During 2008, 7,298 people were diagnosed with HIV in the UK, the 3rd consecutive twelvemonth at that place has been a lessening in diagnosings, though still far higher than the pre-2003 rate. A major constituent of the rapid addition over the past 15 old ages or so has been heterosexually acquired infection. Although merely 20 % of heterosexual infections were, or perchance were, acquired in the UK, these are on the rise. Another important factor has been the debut of clinician coverage, which was merely introduced for HIV diagnosings made after the beginning of 2000. Besides, the usage of HAART ( Highly Active Antiretroviral Therapy ) has proved effectual in detaining HIV associated deceases and the oncoming of AIDS.
There have been several alterations from the early 1980s when HIV was foremost discovered boulder clay now ; several progresss in the intervention of HIV ; awareness runs ; testing and lifestyle alterations has made HIV no longer a decease sentence to many but a chronic status which is manageable. The bulk of people populating with HIV are populating healthier and longer which has led to the additions in the figure of people populating with HIV and a lessening in the figure of people who die from it ( 11 ) . The current tendency in HIV transmittal is different to two decennaries ago when HIV started emerging and several accounts exist for the alterations in the tendency.
Although MSM were responsible for the bulk of new diagnosing up to 1999, the figure of new diagnosings in cheery work forces have been exceeded by those infected through sex between work forces and adult females. The alteration is non because of a diminution in transmittals amongst cheery work forces ( the highest figure of transmittal was observed in 2005 ) but due to increase in transmittals through sex between work forces and adult females. Two tierces of the freshly diagnosed infections in 2005 were from sex between work forces and adult females. ( 4 ) The major factor lending to the rapid rise in the figure of these new HIV diagnoses has been increased heterosexual contact in high HIV prevalence countries, chiefly Africa. Heterosexually acquired infection accounted for around 58 % of new HIV diagnosings in 2008, compared to 38 % that occurred among MSM. In 2008, there were an estimated 4,260 diagnosings attributable to heterosexual contact. ( 18 )
Around 84 % of straight persons freshly diagnosed with HIV in the UK likely acquired their infection abroad, normally prior to migration but besides during travel abroad, although new diagnosings among straight persons who acquired their infection in the UK are besides lifting. ( 5 ) Consequences from clinical tests in Africa ( South Africa, Kenya and Uganda ) which showed decreases in female-to-male sexual HIV transmittal amongst circumcised males have urged the World Health Organisation ( WHO ) and UNAIDS to urge male Circumcision to be recognized as an extra of import intercession in cut downing the hazard of heterosexually acquired HIV infection in work forces, although there is deficient grounds that male Circumcision protects against HIV infection among work forces who have sex with work forces.

Blood merchandises Blood merchandise:
In the 1970s and 1980s in the UK, 4,670 haemophiliac patients were exposed to contaminated blood and blood merchandises through intervention received from the NHS, 1,243 of these patients were infected with HIV some of whom are dead or terminally ill. Large sums of the curdling agent ( factor VIII ) needed by the haemophiliac were imported from the United States because the UK was non self sufficient in blood merchandises so but unknown to the UK authorities, the blood were from high hazard givers. Several steps have since been implemented to cut down the hazard of HIV transmittal through blood merchandises. Individual donor proving now exist which excludes high hazard givers, blood contributions are screened for HIV antibodies and are treated with heat to demobilize the virus. These intercessions have prevented farther transmittal but there is no warrant that an mistake can non happen, although no instance has been reported since, so it works and it is stated that testing has eliminated HIV transmittal through blood merchandises and transfusions in the UK. ( 5 )
HIV infection in pregnant adult females and kids in the UK has continuously been monitored since the late eightiess through unique, population based, active surveillance strategies. Since the debut of intercessions to cut down the hazard of female parent to child HIV infection transmittal, there has been a lessening in transmittal rate of female parent to child transmittal. The rate fell from 20 % to 2 % between 1993 and 1998 and have remained systematically below 2 % since 1999. Although there has been an addition in the figure of HIV infected pregnant adult females diagnosed before bringing from around 60 % in 1999 to over 90 % since 2003, this is as a consequence of the betterment in everyday prenatal HIV proving which was introduced in UK in 1999.
HIV / AIDS continue to be a major planetary wellness precedence. There is increased hazard taking amongst cardinal population sections despite awareness runs on sexual behavior, but there is grounds of successes in HIV bar, there are several authorities enterprises ( bar and intercessions ) for persons most at hazard of HIV and those populating with the status. Treatment has transformed people ‘s lives and the huge bulk of people with HIV can now be after for their hereafter with a great trade of certainty than earlier.
There has been increased consumption of HIV proving and the figure of proving options has besides improved, supplying immediate consequence. However, despite the success, undiagnosed and late diagnosing of HIV remain a challenge with over 25 % of people unaware of their infection, which means they are unable to profit from effectual intervention and hazard inadvertently go throughing HIV on to others. ( 18 ) Improved entree to intervention is holding an impact whist the rapid enlargement of entree to antiretroviral therapy is assisting to take down HIV / AIDS related decease rates, it is besides lending to additions in HIV prevalence.
The go oning rise in the population of people populating with HIV reflects the combined effects of continued high rates of new HIV infections and the good impact of antiretroviral therapy ( 25 )
