The prostitution situation in a number of cities of Russia, Ukraine and Byelarus

The analytical study indicating that 25% of prostitutes use drugs by intravenous injection is presented. As determined in this study, prostitutes face the double danger of being infected with HIV (they undergo treatment for drug addiction and sexually transmitted diseases). The conclusion has been made that no educational work on HIV/AIDS is carried out among this group of women, though they run a high risk of infection. According to this study, the requirements which ensure the health of prostitutes may be realized by itinerary educational programs, the publication of information materials, specially intended for distribution among such women. The necessity to supplement information on AIDS with information on STD is noted, alerting the public on the fact that these infections are closely connected. The necessity of educating transport and industrial workers, as well as people working in the system of the Ministry of Defense, with a view to prevent the spread of HIV infection is also considered to be an important factor (on the example of Belarus).

The epidemiological characteristics of HIV infection in Turkmenistan

In the presence of the low spread of HIV infection a sharp increase in sexually transmitted diseases is noted. Nevertheless, taking into account a rise in STD, the reality of the potential risk of the spread of HIV is emphasized. Thus, in 1996 morbidity is syphilis was found to grow 7.2 times in comparison with 1992, amounting to 37.5 cases per 100,000 of the population; morbidity in gonorrhea amounted to 32.4 cases per 100,000 of the population with the proportion coming to medical institutions not exceeding 30%. A high proportion of hepatitis B virus carriers was also established (from 15% to 30% of healthy persons), while morbidity in virus hepatitides rose twofold for the period of 1994-1995. During recent years the service for the prophylaxis of AIDS was noted to considerably decrease measures on mass screening. At the same time the article attracts attention to the necessity of increasing the work on the dissemination of information and education on HIV/AIDS drug among addicts, prostitutes and homosexuals. The Draft National Program of the Prophylaxis of HIV infection and STD for 1998-2002 has been worked out. Great importance of methodological and financial assistance rendered since 1994 by international organizations, including WHO, UNFPA, etc., have been emphasized.     

Prevalence of hepatitis B markers, antibodies to adult T cell leukemia/lymphoma virus and antibodies to human immune deficiency virus in prostitutes in Fukuoka, Japan

Prevalence of hepatitis B (HB) markers, antibodies to human T cell leukemia virus (HTLV-1) and antibodies to human immune deficiency virus 1 (HIV-1) in prostitutes working in Fukuoka city were studied. Sera were collected from 237 prostitutes during January-September, 1986. Among them, 9 (3.8%) were HB virus surface-antigen (HBs Ag) positive, of whom, 3 were HBe antigen positive and the remaining 6 were anti-HBe positive. The positive rate of anti-HBs was 34.2%. The incidence of anti-HTLV-1 in the prostitutes was 5.9%. These incidences are considered to be within the usual range in Kyushu district. No seropositive case for anti-HIV was found.     

Female streetworking prostitution and HIV infection in Glasgow.

OBJECTIVES--To identify the extent of HIV infection and injecting drug use among female streetworking prostitutes in Glasgow; to estimate the size of the female streetworking prostitute population in the city; and to estimate the number of HIV positive women working as prostitutes on the streets in Glasgow. DESIGN--Observation and interviewing of female prostitutes over seven months in red light district; analysis of saliva samples for presence of antibodies to HIV; capture-recapture approach to estimating the size of the female streetworking prostitute population. SETTING--Glasgow. SUBJECTS--206 female streetworking prostitutes. MAIN OUTCOME MEASURES--Number of women with antibodies to HIV, self reported use of injecting drugs, history of contact with 206 women. RESULTS--Saliva samples were requested from 197 women; 159 (81%) provided samples. Four (2.5%, 95% confidence interval 0.7%-6.3%) of the samples were positive for HIV, all of which had been provided by women who injected drugs. Of the 206 streetworking women contacted 147 (71%) were injecting drug users. About 1150 women are estimated to work on the streets in Glasgow over a 12 month period. CONCLUSIONS--HIV is not as widespread among female prostitutes as many reports in the tabloid press suggest. A greater proportion of female streetworking prostitutes in Glasgow are injecting drugs than has been reported for other British cities.     

Prevalence of Hepatitis B Antigen and Antibody in Prostitutes

We investigated the prevalence of hepatitis B antigen (HBAg) and antibody (HBAb) in 293 prostitutes and in 379 pregnant women of similar age and of low socioeconomic level, who served as controls. HBAg was found in 4·4% of prostitutes and 3·4% of controls. The prevalence of HBAb was significantly higher (P <0·001) in prostitutes (56·7%) than in controls (24·5%). The prevalence of HBAb was clearly age-dependent in both groups. Evidence of hepatitis B virus infection significantly increased with the number of years in prostitution. The evidence of increased infection rates among prostitutes and their distribution support the hypothesis that hepatitis B infection is sexually transmitted.     

四川省自贡市幼儿园3至5岁儿童乙型肝炎病毒感染情况及影响因素

为了解四川省自贡地区3～5岁幼儿乙型肝炎病毒(HBV)感染情况,并探索与感染有关的因素,1985年调查了1167名幼儿,其HBV总感染率为41.13％,HBsAg阳性率12.68％。幼儿的HBV感染与母亲HBsAg阳性密切相关。共检查母亲409例,38例HBsAg阳性,其幼儿HBsAg阳性率为50％(19/38),HBsAg阴性的母亲371例,其幼儿HBsAg阳性率9.97％(37/371),来自HBsAg阳性母亲的阳性子女占33.3％(19/56)。1986年随访HBV易感幼儿448例,HBV年感染率为12.95％(58/448),HBsAg年阳转率3.79％。HBV年感染率与原幼儿班级HBsAg阳性率的高低有关。     

Prostitution and risk of HIV: male partners of female prostitutes.

OBJECTIVE--To describe risk behaviours for infection with HIV in male sexual partners of female prostitutes. DESIGN--A cross sectional study. SETTING--Genitourinary medicine clinic, St Mary''s Hospital, London. SUBJECTS--112 self identified male sexual partners of female prostitutes: 101 who reported commercial sexual relationships only, five who reported non-commercial relationships only, and six who reported both commercial and non-commercial relationships. MAIN OUTCOME MEASURES--Reported risk behaviours for infection with HIV. RESULTS--Of the 40 men who had had previous HIV tests or were tested during the study, two (5%) were infected with HIV. Of the men who would answer the questions, 34/94 reported having sex with other men, 2/105 reported using injected drugs, 8/105 had a history of blood transfusion, 14/108 reported a past history of gonorrhoea, 44/102 reported paying for sex abroad, and 8/92 said that they had also been paid for sex. Of the 55 men who reported paying for vaginal intercourse in the past year, 45 (82%) said that they had always used a condom. In contrast, of the 11 non-paying partners of prostitutes, only two (18%) reported ever using a condom with their partners. CONCLUSIONS--Men who have sex with female prostitutes cannot be assumed to be at risk of infection with HIV only by this route: homosexual contact may place them at greater risk. Despite the heterogeneity among male sexual partners of prostitutes, patterns of use of condoms were uniform when they were considered as a reflection of the type of relationship a man had with a female prostitute rather than a consequence of an individual''s level of risk.     

Human retroviral infections in The Gambia: prevalence and clinical features

The prevalence of infection with human immunodeficiency virus type 1 (HIV 1) is lower in west Africa than in other parts of Africa. Human immunodeficiency virus type 2 (HIV 2) has been isolated from west African patients and may be transmitted by heterosexual contact. The prevalence of antibodies to HIV 1 and HIV 2 was studied by enzyme linked immunosorbent assay (ELISA) among various groups of subjects in The Gambia, west Africa—namely, prostitutes, blood donors, patients with suspected infection with HIV, patients attending clinics for sexually transmitted diseases, and patients with tuberculosis. Four cases of the acquired immune deficiency syndrome (AIDS) due to infection with HIV 1 were detected, of which three had been acquired abroad. No other subject was found to be positive for antibodies to HIV 1. The prevalence of antibodies to HIV 2 among the patients attending clinics for sexually transmitted diseases was found to have increased from 0/117 in 1984 to 10/185 (5%) in the last six months of 1986. One out of 278 blood donors was positive for antibodies to HIV 2 as were 10 out of 80 patients with suspected AIDS.HIV 2 seems to be transmitted sexually, and, although it has been present for only a short time, it seems to be endemic in The Gambia and is pathogenic.     

Human immunodeficiency viruses in patients attending a sexually transmitted disease clinic in London, 1982-7.

OBJECTIVE--To determine the prevalence of infection with the human immunodeficiency virus (HIV) in all patients attending a London sexually transmitted disease clinic over four weeks at the end of 1987 and to see how it varied from that in similar samples studied between 1982 and 1986. DESIGN--Anonymous testing of serum samples from consecutive heterosexual and homosexual patients having routine serological investigations for syphilis. Testing was for anti-HIV-I, anti-HIV-II, and hepatitis B core antibody (anti-HBc) and P24 antigen. Age, nationality, sexual orientation, and past sexually transmitted diseases were recorded for each patient. Gonorrhoea rates by quarters were analysed among homosexual and bisexual men and heterosexual men and women from 1981 to 1987. SETTING--Outpatient department of genitourinary medicine. PATIENTS--A total of 1074 patients attending consecutively for syphilis serology. Thirty five homosexual and bisexual men were excluded (these were regular attenders as part of a prospective study of the natural course of HIV infection). MEASUREMENTS AND MAIN RESULTS--The prevalence of anti-HIV-I in homosexual and bisexual men in 1987 was 25.6% (64/250). Results in the same clinic population between 1982 and 1984 had shown a rise in prevalence, which flattened out in 1985-6 and continued at that level. Among heterosexual attenders in 1987 the prevalence of anti-HIV-I was 1% (women 4/412; men 4/377), which contrasted with a prevalence of 0.5% (women 2/395; men 3/757) in January 1986. One homosexual man was seropositive for anti-HIV-II and seronegative for anti-HIV-I. Among homosexual and bisexual men the rate of gonorrhoea had declined by an average of 2.7% a year since 1981, such that by 1987--and for the first time in the clinic--there was no significant difference in the rates between these men and heterosexual men and women. CONCLUSIONS--The appearance of HIV-I infection among heterosexuals indicates a need for more aggressive education programmes and intervention strategies along the lines adopted for homosexual men. Surveillance for HIV-II infection is needed to provide information for future policy in national screening programmes.     

Tetanus antibody titers and duration of immunity to clinical tetanus infections in free-ranging rhesus monkeys (Macaca mulatta)

Prior to 1985 tetanus was a major cause of mortality in the free-ranging colony of rhesus monkeys on Cayo Santiago, accounting for almost a quarter of annual deaths. In 1985 and 1986 all animals (except infants) received primary and booster doses, respectively, of tetanus toxoid. In subsequent years primary immunizations were given to all yearlings, and boosters were administered to all 2-year-old animals during the annual capture of the colony. The main objectives of the tetanus immunization program were to reduce the pain and suffering caused by tetanus infections and to decrease mortality in the colony. Other objectives were to evaluate the efficacy of the two-dose tetanus toxoid immunization protocol and to determine whether additional boosters might be required to provide adequate long-term protection against tetanus infections. The immediate effect of the mass immunization program was the elimination of clinical tetanus infections in the population and a 42.2% reduction in the overall mortality rate. Since the immunization program began, no cases of tetanus have been observed in the colony, except in two unimmunized infants, and it has not been necessary to give tertiary injections of tetanus toxoid to maintain protection against infection. A sample collected in 2004 of the original cohort of monkeys immunized in 1985 and 1986 showed that 93.3% (14/15) had protective tetanus antibody titers (>0.01 IU/ml) at the ages of 20-23 years, which is close to the life expectancy of the Cayo Santiago rhesus macaques. Two intramuscular doses of tetanus toxoid provided long-term, if not lifelong, protection against tetanus for rhesus monkeys living in a tropical clime where tetanus is enzootic and the risk of infection is great.     

Endocervical Chlamydia trachomatis infection in Canadian adolescents.

The highest prevalence rate of sexually transmitted chlamydial infection is among adolescent girls. To determine the rate among predominantly asymptomatic girls who were seen at a pediatric gynecology unit and to identify those at high risk we screened 541 such patients from Jan. 1 to Dec. 31, 1986, by means of direct fluorescent antibody testing; 422 (78.0%) were asymptomatic. The most common reason for presentation was a request for contraceptive advice (the reason for 59.2% of the patients). Of the 446 patients (82.4%) who were sexually active 66 (14.7%) had evidence of chlamydial infection; none of the 93 sexually inactive patients were infected. Neisseria gonorrhoeae was isolated from eight (1.5%) of the patients. The risk factors that correlated with chlamydial infection were abnormal vaginal discharge, abdominopelvic pain and an abnormal Papanicolaou test result. Because of the high morbidity rate associated with genital chlamydial infection and the high prevalence rate among adolescent girls, most of whom are asymptomatic, all sexually active teenagers should be screened.     

Changes in numbers and growth of Ligula intestinalis in the spottail shiner (Notropis hudsonius), and their roles in transmission

Eighteen species of fishes were collected during the open water (1985-1987) and winter seasons (1985-1986) from Dauphin Lake, Manitoba, Canada (51 degrees 17'N, 99 degrees 48'W) and examined for plerocercoids of Ligula intestinalis (L.). Plerocercoids were most prevalent (5.3%) in spottail shiners (Notropis hudsonius), the major fish host for Ligula in Dauphin Lake. Detailed analysis of the spottail shiner-Ligula host-parasite system revealed that the number of plerocercoids differed between years and among habitats but there was no statistically significant seasonal pattern; recruitment of new worms was highest in young fish and decreased with age, and infected spottails had reduced gonad development. Analysis of host and parasite growth revealed that the soma of male spottails infected with Ligula weighed more but had a reduced growth rate. Growth rate of females was unaffected by Ligula but somatic weight was slightly increased. This appears to be related to the greater metabolic stress on infected males. Based on increased mean somatic weight and skewness of the weight distribution for infected fish, we propose that infected spottails are subjected to size-selective mortality. Some of the contradictions in the literature may be attributed to underestimated prevalence due to increased numbers of spawning fish in the spring, mixed age-classes of Ligula in separate age-classes of fish, and differential effects on growth due to infection in male versus female hosts.     

The first epidemic of acute hemorrhagic conjunctivitis due to a coxsackievirus A24 variant in Okinawa, Japan, in 1985-1986

Epidemics of acute hemorrhagic conjunctivitis due to a coxsackievirus A24 variant occurred in July-November, 1985 and August-October, 1986 in Okinawa Prefecture, Japan. This is the first report of an acute hemorrhagic conjunctivitis epidemic due to a coxsackievirus A24 variant in Japan The epidemic involved most islands of the prefecture. The prefectural surveillance center was notified of 9,952 cases in 1985 and 6,096 cases in 1986 from three sentinel eye clinics. The neutralizing antibody-positive rate against the coxsackievirus A24 variant of the serum samples collected before and immediately after the 1985 epidemic rose from 1.0% to 8.5%. The coxsackievirus A24 variant was isolated from 48 out of 68 conjunctival swabs collected during the epidemics. The isolates were indistinguishable antigenically in the plaque reduction test from the prototype strain, EH24/70, but had a markedly distinct oligonucleotide pattern.

Using death certificates to estimate the completeness of AIDS case reporting in Ontario in 1985-87.

The completeness of AIDS (acquired immune deficiency syndrome) case reporting in Ontario was assessed by reviewing all AIDS death certificates compiled by the Registrar General between Jan. 1, 1985, and Dec. 31, 1987. Several demographic variables were used to match death certificates with cases reported to the provincial AIDS registry. The completeness of case reporting was then estimated by examining the ratio of reported deaths of patients with AIDS to the total number of deaths reviewed. The estimated completeness of case reporting was 81.1% in 1985, 71.5% in 1986 and 75.4% in 1987; the overall rate for 1985-87 was 75.2%. The difference in the completeness of case reporting from year to year was not statistically significant. There was a significant increase from 1985 to 1986 in the proportion of unreported cases in people who had never been married (p less than 0.02). Reporting was not associated with the patient''s age, sex, occupation or place of residence. The deficiency in AIDS case reporting could adversely affect the long-term planning of health care resources and the development of programs to prevent and control the spread of AIDS.     

家庭内性传播疾病感染研究

为了解性传播疾病（ＳｅｘｕａｌｌｙＴｒａｎｓｍｉｔｔｅｄＤｉｓｅａｓｅｓＳＴＤ）对家庭内传播的影响,用多聚酶链反应（ＰＣＲ）等方法检测了９４对夫妻和其中１５户家庭中１６名子女的ＳＴＤ病原体ＮＧ、ＣＴ、ＵＵ、ＨＰＶ、梅毒螺旋体和白色念珠菌。结果表明：男性不洁性史为６８．１５％而女性为４．２６％,两者间有显著差异（Ｐ＜０．０１）,但其发病率无统计上显著差异（男７６．６０％、女７３．４０％）。ＳＴＤ感染以ＣＴ感染最高,达４４．６８％,ＮＧ感染为３１．９１％,ＨＰＶ感染是１５．９６％,未检出梅毒和ＨＳＶ感染。患者中两种及以上病原感染过３５．１１％。５６．２５％的子女ＳＴＤ感染系其患ＳＴＤ父母传染的。这提示如果夫妻任何一方检出有ＳＴＤ感染,另一方须做系统监测与咨询,以便及时采取治疗和预防措施并避免子女受到感染。     

Prostitution and risk of HIV: female prostitutes in London.

OBJECTIVE--To measure the prevalence of HIV and to describe established risk factors in female prostitutes. DESIGN--A cross sectional survey. SETTING--A genitourinary medicine clinic, streets, and magistrates'' courts in London. SUBJECTS--280 female prostitutes recruited between April 1989 and August 1991. MAIN OUTCOME MEASURES--Infection with HIV-1, reported risk behaviours, and prevalence of sexually transmitted infections. RESULTS--228 of the women had HIV tests, and two (0.9% (95% confidence interval 0% to 2.1%)) were infected with HIV-1. Reported use of condoms was high for commercial clients and low for non-paying partners: 98% (251/255) of women used condoms with all clients and 12% (25/207) with non-paying partners for vaginal intercourse. Twenty two women were current or past injecting drug users. Of the 193 women examined for sexually transmitted infections, 27 had an acute infection (gonorrhoea, chlamydia, trichomonas, or primary genital herpes) at the time of interview. Infection was associated with younger age and increasing numbers of non-paying sexual partners, but not with duration of prostitution, numbers of clients, or reports of condom failures. When age and numbers of non-paying partners were analysed by logistic regression they remained significantly associated with sexually transmitted infections. CONCLUSIONS--A large and diverse sample of prostitutes had a low prevalence of infection with HIV and high levels of use of condoms in commercial sex. There was a significant risk of other sexually transmitted infections associated with prostitutes'' non-commercial sexual relationships, in which unprotected sex is common. Interventions to reduce the risk of sexually transmitted infections in prostitutes should address both commercial and non-commercial sexual partnerships.     

Bot fly larvae (Cephenemyia spp., Oestridae) in mule deer (Odocoileus hemionus) from Utah

Ninety-nine mule deer (Odocoileus hemionus) from four Utah counties (Cache, Utah, Sanpete and Sevier) were examined for larvae of Cephenemyia spp. in 1985 and 1986. Numbers of first, second and third stage bot fly instars were related to age, sex, year and geographic location of the mule deer. Fawns and adult deer greater than or equal to 5.5 yr had a significantly (P less than or equal to 0.05) higher intensity (means = 37 and means = 68, respectively) of infection than the 1.5- and 2.5-yr-old age groups (means = 19 and means = 26, respectively). Infection by larvae was not significantly different between sexes. Infection was 100% in both years, but the mean intensity was significantly lower in 1986 (P less than 0.05). The decline may be related to differences in soil moisture between the 2 years. In 1985, 82% of the deer examined were infected with all three instars. Seventy-seven percent of all first instar larvae were observed in the trachea, usually in the fold immediately posterior to the epiglottis and corniculate cartilages. This new site of attachment for first instar larvae has not previously been recognized.
