Introduction
Among sexually transmitted infections (STIs), syphilis is a caused by a spirochete infection, namely, Treponema pallidum.1 It is transmitted through sexual route, mother to child during pregnancy or childbirth.2 The infection affects many sections of body and proceeds through multiple stages, resulting in a wide range of symptoms. The syphilis stages are: Primary Stage: A few weeks after exposure, a painless sore or ulcer called as a chancre develops at infection site, which is typically mouth, anus, or genitalia. After a few weeks, this sore goes away on its own. Secondary Stage: The body, particularly palms and soles, may develop rashes weeks to months after chancre heals. In addition, there may be sore throats, fever, exhaustion, and enlarged lymph nodes. Over course of several weeks, these symptoms could appear and disappear.Latent Stage: If not treated, infection enters a hidden or latent stage where no noticeable symptoms are present. This stage, divided into early-latent and late-latent, can last for years, and during this time, bacteria can still be active in body. Tertiary Stage: Years after the initial infection, syphilis may occasionally advance to this stage if treatment is not received. Serious harm to heart, brain, nerves, bones, and other organs can result from tertiary syphilis. It may result in major health issues and even pose a threat to life.
Direct observation of organisms under dark ground microscope and blood tests that identify antibodies produced in reaction to infection can be used to diagnose syphilis.Early detection and treatment with antibiotics, usually penicillin, are crucial to avoid progression of disease and its complications.1 Partners of infected individuals should also be traced, tested and treated. Using condoms correctly and consistently, limiting number of sexual partners, and receiving regular STI screenings are all important parts of safe sex practices that can prevent syphilis. Pregnant individuals should receive prenatal care to prevent transmitting infection to their babies. If left untreated, syphilis is a dangerous infection with potentially disastrous health effects and complications. Early detection, timely treatment, and preventive measures are key to managing and preventing spread of disease.
Contact tracing is a critical public health practice used to control spread of sexually STIs like syphilis.3, 4 It entails locating and alerting those who could have come into contact with an infected person, so that they can be tested, receive treatment if necessary, and take steps to prevent further transmission. This contact tracing works by following in context of syphilis: Identifying Index Cases, Gathering Information, Notification, Testing and Treatment.
Materials and Methods
With ethics committee clearance, a one-year hospital-based prospective observational study was carried out at Silchar Medical College and Hospital in Silchar, Assam, from November 2022 to October 2023. The study population consisted of 100 cases of male syphilis positive patients had inclusion and exclusion criteria.
Exclusion criteria
All selected patients were attended and a detailed medical and family history, exposure history was taken in each case from patients. Chief complaints, duration of illness, onset of disease, nature of primary lesion(s), evolution of disease, secondary changes if any, associated infection, inflammation were recorded. Specific enquiry was made regarding contacts (men and women) with number of sexual partners, known or unfamiliar to patient, nature of exposure, frequency of exposure, use of contraception. The index patient was asked to give names and location of their sexual contact. History of sexual interaction three months prior to primary syphilis diagnosis, six months prior to secondary syphilis diagnosis, and one year prior to early and late latent syphilis diagnosis.5 After obtaining appropriate consent, contacts were discovered, identified by index patient, and brought to outpatient department for examination and treatment.
Statistical analysis
Following collection and entry into Microsoft Excel spreadsheet, recorded data was transferred to SPSS Version 20.0 (SPSS Inc., Chicago, Illinois, USA) for use as a data editor. To summarize variables, percentages and frequencies were employed. The statistics were graphically illustrated using pie and bar diagrams. P values were deemed statistically significant if they were less than 0.05.
Results
Our study comprised a total of 100 male syphilis patients who tested positive for both TPHA and RPR. Table 1 indicates that 45 patients (45%) fit to age group of 21–30 years, and 24 patients (24%) belonged to age group of 31–40 years followed by 17 patients (17%) in 41-50 years age group, 10 patients (10%) in 51-60 years age group and least in 18-20 years age group that is 4 patients (4%).
Male patients reported engaging in sex with women only (MSWO) in 68 cases (68%), sex with men (MSM) in 27 cases (27%), and sex with male and female both partners in 5 cases (5%) as depicted in pie diagram 1. 16 (16%) of 100 patients were receiving anti-retroviral medication and had PLHA status.
Table 2 indicates that, out of 100 cases, 22 (22%) were classified as primary, 10 (10%) as secondary, and 68 (68%) as latent syphilis. The distribution of syphilis stages did not show any discernible differences between heterosexual men, MSM, and women.

The index patient is asked to list the number of "contacts," or partners, he has had sex with during the interview process. While MSM index patients reported having 162 total sexual partners during the infection period and named 80 (49%), MSWO index patients reported having 340 total sexual partners and named 224 (65.8%). Patients on the MSWO reported having more sexual partners than those on the MSM index (p = 0.16).
Twenty (52.6%) of the 38 sexual partners of index patients with both MSWO and MSM behaviour reported were named. 22 of 27 (81.4%) MSM index patients did not name any contacts, whereas 46 of 68 (67.6%) MSWO patients did (p value = 0.08).
The contacts were deemed to have been "exposed to infection," necessitating a check-up, serological testing, and a "routine examination–no symptoms." RPR with titre and TPHA with titre are performed to support diagnosis. Table 4 shows that of 326 contacts, 96 (or 29.4%) were diagnosed as primary syphilis, 41 (12.5%) as secondary syphilis, and 189 (or 57.9%) as latent syphilis. Although the percentage of contacts with infectious (primary and secondary) syphilis was higher in patients with an MSWO index cases, this difference was not statistically significant.

Discussion
In order to break the chain of transmission, it is advised that partners be informed after a sexually transmitted infection (STI) diagnosis.
MSWO index patients reported higher number of contacts (340 contacts) as compared to MSM index patients (162 contacts). A higher incidence of late latent syphilis was found amongst contacts who were symptomless (52.7%). There is significant association between syphilis seropositivity and PLHA status.
As opposed to urban areas in many industrialized countries3, 4, 5, 6 where more MSM behavior have been reported, it has not of much prevalence in North-East India. This may be due to cultural norms and lack of social exposure. A difference of sexual practices is also seen in North-East India as per our study. Compared to our study, more MSM index patients than MSWO index patients report anonymous partners in studies like Fulton County (56%) and elsewhere.7, 8, 9 It makes sense to believe that various contact-tracing results could happen. However, summaries of contacts discovered or diagnosed with syphilis would not demonstrate variations in contact-tracing outcomes if MSM index patients named approximately the same number of contacts as MSWO index patients. Rather, the difference may show up as more unidentified sexual partners.
Social stigma, fear of identity disclosure, social boycott, and the high proportion of index patients obtaining care from private providers—all of which have been proposed as reasons for poor contact-tracing efficacy between MSM, may have had an impact on contact tracing efforts in our study. 10, 11
A key challenge to effectiveness of contact tracing is stigma, which is defined as negative attitude or conduct towards an individual or group who shares recognizable symptoms of health condition or disease.12 Evidence suggests that most significant instances of stigmatization around a medical condition occur when condition is linked to acts or behaviours that are thought to be at odds with social norms.13
In the end, a sizable portion of case-patients were unreachable for an interview. The presence of their unidentified contacts may provide the impression that the contact-tracing yield for MSM and MSWO is the same, even if it is conceivable that these case-patients were more likely to be MSM.
Diagnosis of HIV, syphilis, and gonorrhea, including asymptomatic sexual contacts, is greatly aided by contact tracing in our population.14, 15 In MSM's sexual networks, more attempts to boost contact tracking yield may help lower prevalence of gonorrhea, syphilis, and HIV.
Conclusion
In scenario of rising rates of STDs among population, syphilis makes a notable contribution. This is due to its disease course with no aberrant clinical symptoms that alarm patients. Therefore, it becomes a necessity for screening of population, especially those who are in contact with infected individuals. Contact tracing holds key in controlling this infection. Patient education and public awareness regarding disease and its outcome and treatment are equally important in controlling syphilis.
