73 Significant risks are also associated with invasive procedures, assisted delivery, and dental care in this area of the world. 73 people giving or receiving tattoos, piercings, and scarification are theoretically at risk of infection but no confirmed cases have been documented. 74 It is not possible for mosquitoes or other insects to transmit hiv. 75 Mother-to-child main articles: hiv and pregnancy and hiv and breastfeeding hiv can be transmitted from mother to child during pregnancy, during delivery, or through breast milk, resulting in the baby also contracting hiv. 76 77 This is the third most common way in which hiv is transmitted globally. 12 In the absence of treatment, the risk of transmission before or during birth is around 20 and in those who also breastfeed., vertical transmission accounted for about 90 of cases of hiv in children. 77 With appropriate treatment the risk of mother-to-child infection can be reduced to about. 77 Preventive treatment involves the mother taking antiretrovirals during pregnancy and delivery, an elective caesarean section, avoiding breastfeeding, and administering antiretroviral drugs to the newborn.

12 Blood-borne transmission can be through needle-sharing during intravenous drug use, needle stick injury, transfusion of contaminated blood or blood product, or medical injections with unsterilized equipment. The risk from sharing a needle during drug injection is between.63 and.4 per act, with an average.8. 66 The risk of acquiring hiv from a needle stick from an hiv-infected person is estimated.3 (about 1 in 333) per act and the risk following mucous membrane exposure to infected blood.09 (about 1 in 1000) and per act. 49 In the United States intravenous drug users made up 12 of all new cases of hiv in 2009, 67 and in some areas more than 80 of people who inject drugs are hiv positive. 12 hiv is transmitted in about 93 of blood transfusions using infected blood. 66 In developed countries the risk of acquiring hiv from a blood transfusion is extremely low (less than one in half report a million) where improved donor selection and hiv screening is performed; 12 for example, in the uk the risk is reported at one. 69 In low income countries, only half of transfusions may be appropriately screened (as of 2008 70 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. 12 71 Although rare because of screening, it is possible to acquire hiv from organ and tissue transplantation. 72 Unsafe medical injections play a significant role in hiv spread in sub-Saharan Africa. In 2007, between 12 and 17 of infections in this region were attributed to medical syringe use. 73 The world health Organization estimates the risk of transmission as a result of a medical injection in Africa.2.

53 Other sexually transmitted infections, such as gonorrhea, chlamydia, trichomoniasis, and bacterial vaginosis, are associated with somewhat smaller increases in risk of transmission. 58 The viral load of an infected person is an important risk factor in both sexual and mother-to-child transmission. 60 During the first.5 months of an hiv infection a person's infectiousness is twelve times higher due to plan the high viral load associated with acute hiv. 58 If the person is in the late stages of infection, rates of transmission are approximately eightfold greater. 53 An hiv-positive person who has an undetectable viral load as a result of long-term treatment has effectively no risk of transmitting hiv sexually. 61 Commercial sex workers (including those in pornography ) have an increased rate of hiv. 62 63 rough sex can be a factor associated with an increased risk of transmission. 64 Sexual assault is also believed to carry an increased risk of hiv transmission as condoms are rarely worn, physical trauma to the vagina or rectum is likely, and there may be a greater risk of concurrent sexually transmitted infections. 65 Body fluids cdc poster from 1989 highlighting the threat of aids associated with drug use The second most frequent mode of hiv transmission is via blood and blood products.

53 In low-income countries, the risk of female-to-male transmission is estimated.38 per act, and of male-to-female transmission.30 per act; the equivalent estimates for high-income countries are.04 per act for female-to-male transmission, and.08 per act for male-to-female transmission. 53 The risk of transmission from anal intercourse is especially high, estimated.41.7 per act in both heterosexual and homosexual contacts. 53 54 While the risk of transmission from oral sex is relatively low, it is still present. 55 The risk from receiving oral sex has been described as "nearly nil 56 however, a few cases have been reported. 57 The per-act risk is estimated.04 for receptive oral intercourse. 58 In settings involving prostitution in low income countries, risk of female-to-male transmission has been estimated.4 per act and male-to-female transmission.05 per act. 53 Risk nashville of transmission increases in the presence of many sexually transmitted infections 59 and genital ulcers. 53 Genital ulcers appear to increase the risk approximately fivefold.

12 There is no risk of acquiring hiv if exposed to feces, nasal secretions, saliva, sputum, sweat, tears, urine, or vomit unless these are contaminated with blood. 49 It is also possible to be co-infected by more than one strain of hiv—a condition known as hiv superinfection. 50 Sexual The most frequent mode of transmission of hiv is through sexual contact with an infected person. 12 Globally, the most common mode of hiv transmission is via sexual contacts between people of the opposite sex ; 12 however, the pattern of transmission varies among countries. As of 2014, most hiv transmission in the United States occurred among men who had sex with men (83 of new hiv diagnoses among males aged 13 and older and 67 of total new diagnoses). 51 In the us, gay and bisexual men aged 13 to 24 accounted for an estimated 92 of new hiv diagnoses among all men in their age group and 27 of new diagnoses among all gay and bisexual men. 51 About 15 of gay and bisexual men have hiv while 28 of transgender women test positive in the. 51 52 With regard 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 countries.

They represent approximately 1 in 300 infected persons. 34 Acquired immunodeficiency syndrome main symptoms of aids.

Acquired immunodeficiency syndrome (aids) is defined in terms of either a cd4 T cell count below 200 cells per µL or the occurrence of specific diseases in association with an hiv infection. 28 In the absence of specific treatment, around half of people infected with hiv develop aids within ten years. 28 The most common initial conditions that alert to the presence of aids are pneumocystis pneumonia (40 cachexia in the form of hiv wasting syndrome (20 and esophageal candidiasis. 28 Other common signs include recurrent respiratory tract infections. 28 Opportunistic infections may be caused by bacteria, viruses, fungi, and parasites that are normally controlled by the immune system. 35 Which infections occur depends partly on what organisms are common in the person's environment.

28 neurological symptoms of peripheral neuropathy or guillainBarré syndrome also occurs. 28 The duration of the symptoms varies, but is usually one or two weeks. 28 due to their nonspecific character, these symptoms are healthy not often recognized as signs of hiv infection. Even cases that do get seen by a family doctor or a hospital are often misdiagnosed as one of the many common infectious diseases with overlapping symptoms. Thus, it is recommended that hiv be considered in people presenting with an unexplained fever who may have risk factors for the infection. 28 Clinical latency The initial symptoms are followed by a stage called clinical latency, asymptomatic hiv, or chronic hiv. 1 Without treatment, this second stage of the natural history of hiv infection can last from about three years 30 to over 20 years 31 (on average, about eight years). 32 While typically there are few or no symptoms at first, near the end of this stage many people experience fever, weight loss, gastrointestinal problems and muscle pains.

Hiv is spread primarily by unprotected sex (including anal and oral sex contaminated blood transfusions, hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding. 12 Some bodily fluids, such as saliva and tears, do not transmit hiv. 13 Methods of prevention include safe sex, needle exchange programs, treating those who are infected, and male circumcision. 5 Disease in a surgery baby can often be prevented by giving both the mother and child antiretroviral medication. 5 There is no cure or vaccine ; however, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy. 6 7 Treatment is recommended as soon as the diagnosis is made. 14 Without treatment, the average survival time after infection is 11 years.
