10 RISK OF SYPHILIS TRANSMISSION
Sexual transmission %  Risk of sexual transmission is concentrated in early syphilis, when moist mucocutaneous lesions of primary and secondary syphilis are present. Transmission is rare after first-second year from infection. Fetal infection is a result of haematogenous spread, dependent on spirochaetemia that is present in early stage, although transmission at delivery can result from direct contact with infectious genital lesions. The main factors that determine the probability of fetal transmission are stage of maternal infection and duaration of exposure in utero Vertical transmission % 10

11 Number of primary and secondary syphilis cases among men who have sex with men, by race/ethnicity — National Notifiable Diseases Surveillance System, 34 states* and the District of Columbia with complete sex partner data,† 2009–2012 MMWR stampato The increase in syphilis among MSM is a major public health concern, particularly because syphilis and the behaviors associated with acquiring it increase the likelihood of acquiring and transmitting human immunodeficiency virus (HIV) (6). There are reported rates of 50%–70% HIV coinfection among MSM infected with primary and secondary syphilis (7) and high HIV seroconversion rates following primary and secondary syphilis infection (8).  MMWR 2014, 63(18)

12 SYPHILIS - USA (15): (INDIANA) RISING INCIDENCE, MEN WHO HAVE SEX WITH MEN ************************************************************************** A ProMED-mail post ProMED-mail is a program of the International Society for Infectious Diseases Date: Fri 30 Oct The Tippecanoe County Health Department is tracking an increase in the number of syphilis cases in the area. This year [2015], there have been 12 reports of syphilis in Tippecanoe County compared with fewer than 5 reports in each the of the previous 4 years, the health department said on Friday [30 Oct 2015]. Local and state health departments are partnering to "closely monitor this trend, educate the public and health care providers about syphilis, and help facilitate proper testing and treatment of affected individuals," according to a press release from the department. Jeremy Adler, the county department's health officer, said anecdotal reports suggest those contracting the infection are engaged in risky sexual behavior with multiple partners. Adler said that smartphone apps such as Tinder that facilitate random sexual encounters, could be contributing to the issue. He noted the disease is spread through sexual contact and not through drug use, such as sharing needles. "Syphilis is often viewed as a disease that happened a long time ago that was a problem in the old days," Adler said. "But clearly, this shows that it still can be a big problem, and it's something that we have to really be aware of and educate the public about." Statewide, Indiana is following the same trend. More than 350 cases of syphilis were reported between 10 Jan-3 Oct of this year [2015], representing a 53 per cent increase from last year, according to a press release from the Indiana State Department of Health. "This is an alarming increase in the number of people being diagnosed with a preventable and curable disease," state health commissioner Jerome Adams said in the release. Most cases have occurred in men who have had sexual contact with other men, although some heterosexual cases have been reported, according to the state's information. Syphilis is a sexually contracted infection and in certain stages can cause symptoms including sores, fever, muscle aches and weight loss.

23 SYPHILIS - AUSTRALIA (02): (NORTHERN TERRITORY, WESTERN AUSTRALIA) INCREASE, INDIGENOUS PEOPLE, CONGENITAL ********************************************************************************************************** Date: Sun 1 Nov Health authorities are scrambling to contain an outbreak of syphilis that is believed to have claimed the lives of 10 babies across northern Australia. Professor Basil Donovan, of the Sydney-based Kirby Institute, said while instances of the sexually transmitted infection (STI) were in decline, an outbreak that started in northern Queensland in 2011 had swept across the Top End. "We got a large outbreak amongst very young people in the Gulf country in Queensland, and since that time it's turned up in the Katherine area of the Northern Territory and then swept across the Kimberley [Western Australia]," he said. "We worry because if pregnant women catch syphilis, the result is very frequently disastrous. It leads to loss of pregnancy, stillbirths, [births] of very disabled babies." Professor Donovan said 10 babies had died as a result of congenital syphilis since the outbreak began. "A rich country like Australia, shouldn't really be seeing any deaths," he said. The Kirby Institute's national surveillance system showed 2000 new cases were diagnosed in As of [30 Oct 2015], another 1972 cases had been recorded in 2015, making it the most severe Australian outbreak in 30 years. The only other group affected outside of northern Aboriginal communities are urban gay communities. Professor Donovan said in cities like Melbourne, Sydney, and Perth, the STI was almost entirely limited to gay men. Syphilis can cause dementia, blindness, [and] brain damage. Syphilis can be cured with a simple course of antibiotics, but if left untreated the STI can have serious health impacts, including dementia, blindness, and permanent damage to the heart and brain. The northern outbreak crossed the NT border into WA last year [2014] and health authorities in the Kimberley are trying to contain its spread. Broome-based sexual health nurse Katy Crawford said for the 2 years to June 2014, the region had been syphilis-free. But since then, more than 40 people had been infected, and dozens more may be carrying it without realising. "It is a significant health concern for the region, and we expect this outbreak to continue for a number of months to years," he said. "It will be difficult to contain unless we get more people tested, and more people practising safe sex.“ Another challenge was finding materials suitable to Indigenous teenagers with often limited English and no understanding of sexual health. "A lot of resources that we have available are created in a metro area where there's very high literacy, so we're trying to create locally appropriate resources," Ms Sibosado said. "One campaign we've started is around the rodeo round that happens up here in the Kimberley, encouraging people to have safe sex, and letting them know where to get more information." The campaign includes condom wallets and posters featuring a rugged looking Aboriginal rodeo rider looking for love

Salute sessuale e riproduttiva: La prevenzione, la diagnosi periodica e la cura di tutte le IST dell’assistito e/o infezioni che abbiano a che fare comunque con la sfera sessuale, quindi intese nel senso più ampio del termine. Lo screening deve essere eseguito a tutte le persone con HIV al momento della diagnosi e con periodicità almeno annuale [AI]. Tale tempistica è da ridefinirsi [BIII]: Secondo lo stile di vita della persona, in accordo con il curante; Nel caso vengano riportate o riscontrate sintomatologie riguardanti le IST; Quando la persona con HIV appartiene a popolazioni ‘epidemiologicamente’ più a rischio per IST

There was no difference in the proportion of subjects in each group whose CSF measures improved. Significantly more ceftriaxone recipients had a decline in serum RPR titers (8 [80%] of 10 vs. 2 [13%] of 15; P = .003). Differences in the 2 groups limit comparisons between them. However, iv ceftriaxone may be an alternative to penicillin for treatment of HIV-infected patients with neurosyphilis and concomitant early syphilis. Marra CM, et al.
