The initial symptoms are followed by a stage called clinical latency, asymptomatic HIV, or persistent HIV. 1 Without treatment, this second phase of the natural history of HIV disease can continue from around three years 28 to over 20years 29 (on average, about eight years). 30 While usually there are few or no symptoms initially, close to the end of this stage many people experience weight loss, fever, gastrointestinal difficulties and muscle pains. 1 Between 50 and 70% of individuals also grow persistent generalized lymphadenopathy , defined by unexplained, non-painful enlargement of more than one group of lymph nodes (other than in the groin) for over three to six months.

Although most HIV-1 infected people have a detectable viral load and in the lack of treatment will eventually progress to AIDS, a tiny proportion (about 5%) keep elevated rates of CD4 T cells ( T helper cells ) without antiretroviral therapy for more than 5 years. 26 31 These individuals are classified as HIV controllers or long-term nonprogressors (LTNP). 31 Another group consists of those who keep a low or undetectable viral load without anti-retroviral treatment, known as "top-notch controllers" or "elite suppressors". They represent around 1 in 300 persons that are contaminated. Garneill Montana Std Test. 32

Acquired immunodeficiency syndrome (AIDS) is defined in terms of either a CD4 T cell count below 200 cells per L or the incidence of specific diseases in association with an HIV infection. Std test in Garneill Montana, United States. 26 In the lack of special treatment, around half of individuals infected with HIV develop AIDS within ten years. 26 The most often occurring first conditions that alert to the presence of AIDS are pneumocystis pneumonia (40%), cachexia in the form of HIV wasting syndrome (20%), and esophageal candidiasis 26 Other common signs include recurring respiratory tract infections 26

Individuals with AIDS have a higher risk of developing various viral-induced cancers, including Kaposi's sarcoma , Burkitt's lymphoma , primary central nervous system lymphoma , and cervical cancer 27 Kaposi's sarcoma is the most frequent cancer occurring in 10 to 20% of people with HIV. 35 The second most common cancer is lymphoma, that is the first indication of AIDS in 3 to 4% and is the cause of death of nearly 16% of people who have AIDS. 35 Both these cancers are linked with human herpesvirus 8 35 Cervical cancer occurs more frequently in people that have AIDS due to its association with human papillomavirus (HPV). 35 Conjunctival cancer (of the layer that lines the interior part of eyelids and the white part of the eye) is also more prevalent in those with HIV. 36

The most common mode of transmission of HIV is through sexual contact with an infected individual. 11 The majority of all transmissions worldwide occur through heterosexual contacts (i.e. sexual contacts between individuals of the opposite sex); 11 however, the pattern of transmission varies significantly among states. As of 2014, most HIV transmission in the United States occurred among men who had sex with men, with this people accounting for 67% of new cases and 83% of new cases among males over 12 years old. While 28 percent of transgender women test positive 49 About 15% of homosexual and bisexual guys have HIV. 49 50 Std Test closest to Garneill.

With respect to unprotected heterosexual contacts, estimates of the risk of HIV transmission per sexual act appear to be four to ten times higher in low income countries than in high income states. 51 In low income nations, the risk of female to male transmission is estimated as 0.38% per act, and of male to female transmission as 0.30% per action; the equivalent approximations for high income states are 0.04% per act for female to male transmission, and 0.08% per act for male to female transmission. 51 The danger of transmission from anal intercourse is especially high, estimated as 1.4-1.7% per action in both heterosexual and homosexual contacts. 51 52 While the danger of transmission from oral sex is relatively low, it is still present. 53 The risk from receiving oral sex was described as "nearly nil"; 54 nevertheless, a few cases are reported. 55 The per-act risk is estimated at 0-0.04% for receptive oral sex. 56 In settings involving prostitution in low income countries, risk of female-to-male transmission has been estimated as 2.4% per action and male to female transmission as 0.05% per act. 51

The next most common mode of HIV transmission is via blood and blood products. 11 Blood-borne transmission can be through needle-sharing needle stick injury, during intravenous drug use, transfusion of infected blood or blood product, or medical shots with unsterilized equipment. The danger from sharing a needle during drug injection is between 0.63 and 2.4% per act, with an average of 0.8%. Std Test nearby MT, United States. 63 The risk of getting HIV from a needle stick from an HIV-infected person is estimated as 0.3% (about 1 in 333) per action and the danger following mucous membrane exposure to contaminated blood as 0.09% (about 1 in 1000) per action. 47 In America intravenous drug users made up 12% of all new cases of HIV in 2009, 64 and in a few places more than 80% of people who inject drugs are HIV positive. 11

HIV is transmitted in about 93% of blood transfusions using contaminated blood. 63 In developed countries the risk of acquiring HIV from a blood transfusion is extremely low (less than one in half a million) where improved donor selection and HIV screening is performed; 11 for instance, in the UK the danger is reported at one in five million 65 and in the United States it was one in 1.5 million in 2008. 66 In low income countries, only half of transfusions may be appropriately screened (as of 2008), 67 and it is estimated that up to 15% of HIV infections in these areas come from transfusion of infected blood and blood products, representing between 5% and 10% of global infections. Std test near me MT United States. 11 68 Although rare because of screening, it really is possible to get HIV from tissue and organ transplantation 69

HIV can be transmitted from mother to child during pregnancy, during delivery, or through breast milk resulting in infection in the baby. 73 74 This is the third most common manner in which HIV is transmitted internationally. 11 In the lack of treatment, the risk of transmission before or during birth is around 20% and in those who also breastfeed 35%. 73 As of 2008, perpendicular transmission accounted for about 90% of cases of HIV in children. 73 With appropriate treatment the risk of mother-to-child infection could be reduced to about 1%. 73 Preventative treatment involves the mother avoiding breastfeeding, taking antiretrovirals during pregnancy and delivery, an elective caesarean section, and administering antiretroviral drugs to the newborn. 75 Antiretrovirals when taken by the mother or the baby decline the danger of transmission in those who do breastfeed. 76 Many of these measures are however not accessible the developing world. 75 If food is contaminated by blood during pre- chewing it may pose a risk of transmission. 71

HIV is an associate of the genus Lentivirus , 79 part of the family Retroviridae 80 Lentiviruses share many morphological and biological features. Many species of mammals are infected by lentiviruses, which are characteristically responsible for long-duration illnesses with an extended incubation period 81 Lentiviruses are transmitted as single stranded, positive- sense , enveloped RNA viruses Upon entrance into the target cell, the viral RNA genome is converted (reverse transcribed) into double-stranded DNA by a virally encoded reverse transcriptase that's transported together with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded integrase and host cofactors. 82 Once incorporated, the virus may become latent, allowing its own host cell and the virus to prevent detection by the immune system. 83 Instead, the virus may be transcribed, producing viral proteins that are packaged and discharged from the cell as new virus particles that begin the replication cycle anew and new RNA genomes. 84

HIV is now known to spread between CD4 T cells by two parallel routes: cell-free spread and cell-to-cell spread, i.e. it applies hybrid propagating mechanisms. 85 In the cell-free spread, virus particles bud from an infected T cell, enter the blood/extracellular fluid after which infect another T cell following a chance encounter. 85 HIV may also disseminate by direct transmission from one cell to another by a procedure for cell-to-cell spread. Std Test near Garneill Montana. 86 87 The hybrid dispersing mechanisms of HIV contribute to the virus's ongoing replication against antiretroviral treatments. 85 88

There's a period of rapid viral replication, resulting in an abundance of virus in the peripheral blood after the virus enters the body. During primary infection, the amount of HIV may reach several million virus particles per milliliter of blood. 91 This reaction is accompanied by a noticeable drop in the amount of circulating CD4 T cells. The acute viremia is almost always related to activation of CD8 T cells , which kill HIV-infected cells, and subsequently with antibody generation, or seroconversion The CD8 T cell response is thought to be important in controlling virus degrees, which peak and then decline, as the CD4 T cell counts recover. Though it doesn't remove the virus a great CD8 T cell response has been linked to slower disease progression and also a better prognosis. 92

Ultimately, HIV causes AIDS by depleting CD4 T cells the immune system weakens and allows opportunistic infections T cells are essential to the immune response and without them, the body cannot fight illnesses or kill cancerous cells. The mechanism of CD4 T cell depletion differs in the acute and chronic periods. 93 During the acute phase, HIV-induced cell lysis and killing of infected cells by cytotoxic T cells accounts for CD4 T cell depletion, although apoptosis might also be a factor. During the chronic stage, the results of generalized immune activation coupled with the gradual loss of the ability of the immune system to generate new T cells appear to account for the slow decline in CD4 T cell numbers. 94

While the symptoms of immune deficiency characteristic of AIDS don't appear for decades after a person is infected, the bulk of CD4 T cell loss happens during the first weeks of infection, particularly in the intestinal mucosa, which harbors nearly all the lymphocytes found in the body. 95 The reason for the preferential loss of mucosal CD4 T cells is that the majority of mucosal CD4 T cells express the CCR5 protein which HIV uses as a co-receptor to gain access to the cells, whereas merely a little fraction of CD4 T cells in the bloodstream do thus. 96 A specific genetic change that alters the CCR5 protein when present in both chromosomes very effectively prevents HIV-1 infection. 97

HIV seeks out and destroys CCR5 expressing CD4 T cells during acute disease. 98 A vigorous immune response begins the clinically latent period and controls the disease. CD4 T cells in mucosal tissues remain especially impacted. 98 Continuous HIV replication causes a state of generalized immune activation continuing throughout the chronic stage. 99 Immune activation, which is reflected by the increased activation state of immune cells and release of pro inflammatory cytokines, results from the action of several HIV gene products as well as the immune response to ongoing HIV replication. It's also linked to the breakdown of the immune surveillance system of the gastrointestinal mucosal barrier brought on by the depletion of mucosal CD4 T cells during the acute phase of disease. 100

Garneill, MT std test. HIV/AIDS is diagnosed via lab testing and then staged based on the existence of certain signs or symptoms 24 HIV screening is advocated by the United States Preventive Services Task Force for all individuals 15years to 65years of age including all pregnant women. 101 Furthermore, testing is recommended for those at high risk, which comprises anyone. 27 In many regions of the planet, a third of HIV carriers just discover when AIDS or severe immunodeficiency has become evident, they are infected at an advanced phase of the disorder.

Antibody evaluations in kids younger than 18months are typically inaccurate because of the continued existence of maternal antibodies 102 Thus HIV disease can only be diagnosed by PCR testing for HIV RNA or DNA, or via testing for the p24 antigen. 24 Much of the world lacks access to reliable PCR testing and several areas just wait the kid is old enough for exact antibody testing or until either symptoms develop. 102 In sub Saharan Africa as of 2007-2009 between 30 and 70% of the people were informed of their HIV status. Garneill std test. 103 In 2009, between 3.6 and 42% of men and women in Sub Saharan nations were analyzed 103 which signified a considerable increase compared to previous years. 103

Two primary clinical staging systems are used to classify HIV and HIV-associated disease for surveillance purposes: the WHO disease staging system for HIV infection and disease , 24 and the CDC classification system for HIV infection 104 The CDC 's classification system is more often adopted in developed nations. Since the WHO 's staging system does not require laboratory evaluations, it is suited to the resource-restricted states encountered in developing countries, where it can be used to help guide clinical management. Despite their differences, the two systems allow comparison for statistical purposes. 2 24 104

Consistent condom use reduces the risk of HIV transmission by approximately 80% over the long term. 106 When condoms are used consistently by a couple in which one individual is infected, the rate of HIV infection is less than 1% per year. 107 There is some evidence to imply that female condoms may offer an equal degree of protection. Std Test nearest Garneill. 108 Application of a vaginal gel containing tenofovir (a reverse transcriptase inhibitor ) immediately before sex appears to lessen infection rates by about 40% among African women. 109 By contrast, use of the spermicide nonoxynol-9 may increase the risk of transmission due to its tendency to cause vaginal and rectal irritation. 110

Circumcision in Sub-Saharan Africa "reduces the acquisition of HIV by heterosexual men by between 38% and 66% over 24 months". 111 Due to these studies, both UNAIDS and the World Health Organization recommended male circumcision as a method of preventing female-to-male HIV transmission in 2007 in regions using a high rates of HIV. 112 Nevertheless, whether it shields against male to female transmission is challenged, 113 114 and whether it's of benefit in developed nations and among men who have sex with men is undetermined. 115 116 117 The International Antiviral Society, nevertheless, does that it be discussed with men who have sex with men as an alternative and advocate for all sexually active heterosexual males. 118 Some experts fear that a lower perception of exposure among circumcised men may cause more sexual risk taking behavior, thus negating its prophylactic effects. 119

Plans encouraging sexual abstinence don't seem to impact subsequent HIV danger. 120 Evidence of any gain from peer instruction is equally inferior. 121 Complete sexual education provided at school may decrease high risk behavior. 122 A sizeable minority of young people continues to engage in high risk practices despite understanding about HIV/AIDS, underestimating their own danger of becoming infected with HIV. Std test in MT, United States. 123 Voluntary counselling and testing individuals for HIV doesn't influence risky behavior in individuals who test negative but does raise condom use in individuals who test positive. 124 It isn't understood whether treating other sexually transmitted infections is effective in preventing HIV. 57

Antiretroviral treatment among people with HIV whose CD4 count 550 cells/L is quite an productive method to prevent HIV disease of their partner (a strategy called treatment as prevention, or TASP). Std test in Garneill Montana United States. 125 TASP is related to a 10 to 20 fold reduction in transmission risk. 125 126 Pre-exposure prophylaxis (homework) with a daily dose of the medications tenofovir , with or without emtricitabine , is successful in several groups including men who have sex with men, couples where one is HIV positive, and youthful heterosexuals in Africa. 109 It might also be successful in intravenous drug users using a study finding a drop in risk of 0.7 to 0.4 per 100personyears. 127

Present HAART choices are combinations (or "cocktails") consisting of at least three drugs belonging to at least two kinds, or "groups," of antiretroviral agents. 144 Initially treatment is commonly a non-nucleoside reverse transcriptase inhibitor (NNRTI) plus two nucleoside analogue reverse transcriptase inhibitors (NRTIs). 145 Typical NRTIs comprise: zidovudine (AZT) or tenofovir (TDF) and lamivudine (3TC) or emtricitabine (FTC). 145 Combinations of agents which include protease inhibitors (PI) are used if the aforementioned regimen loses effectiveness. 144

United States and the World Health Organization recommends antiretrovirals in individuals of all ages including pregnant women as soon as the diagnosis is made regardless of CD4 count. 14 118 146 After treatment is begun it's advised that it's continued without breaks or "holidays". 27 Many people are diagnosed just after treatment ideally should have begun. 27 The desirable results of treatment is a long-term plasma HIV-RNA count below 50copies/mL. 27 Degrees to find out if treatment is successful are initially urged after four weeks and once degrees drop below 50copies/mL tests every three to six months are typically sufficient. 27 Insufficient control is deemed to be greater than 400copies/mL. 27 Based on these criteria treatment is successful in more than 95% of individuals during the first year. 27

Advantages of treatment include a reduced danger of departure and a decreased risk of progression to AIDS. Std Test near Garneill, Montana. 147 In the developing world treatment also enhances physical and mental health. 148 With treatment there's a 70% reduced risk of acquiring tuberculosis. 144 Additional advantages include a decreased danger of transmission of the illness to sexual partners as well as a reduction in mom-to-child transmission. 144 The effectiveness of treatment depends to a big part on conformity. 27 Motives for non-adherence include poor access to medical care, 149 insufficient social supports, mental illness and drug abuse 150 The intricacy of treatment regimens (due to pill numbers and dosing frequency) and adverse effects may reduce adherence. 151 though cost is an important problem with some medicines, 152 47% of people who wanted them were taking them in the rate of adherence and also low and middle income countries as of 2010 143 is comparable in low-income and high-income countries. 153
