1. Sexually transmitted diseases (STDs) are caused by bacteria, viruses, parasites or fungi transmitted through sexual contact. Common STDs include chlamydia, gonorrhea, HIV/AIDS, herpes and syphilis.
2. India has a major problem with STDs, with millions of new infections acquired each year. High-risk groups include sex workers, their clients like truck drivers, and individuals with multiple partners or broken homes.
3. Syndromic management is used to clinically diagnose and treat STDs based on symptoms rather than definitive diagnostic testing. It is effective against mixed infections but can promote antibiotic resistance.

2. Introduction
⢠Group of communicable diseases that are transmitted predominantly by sexual
contact and caused by wide range of bacterial, viral ,protozoal and fungal agents
and ectoparasites.
⢠In the last few decades , STDs have undergone a dramatic transformation.
a) Venereal disease to STDs.
b) List of pathogen extended from 5 to more than 20.
c) Not only symptoms are important but also the clinical syndrome associated with
this diseases.
3. Problem statement
⢠True incidence-not known because of inadequate reporting due to
secrecy that surrounds them.
⢠More that 1 million STIs are acquired every day.
⢠Each year, there are estimated 357 million new infections with 1 of 4
STIs.
⢠STIs have serious consequences beyond the immediate impact of the
infection itself like mother to child transmission of STIs can result in
still birth neonatal death, LBW , PID and infertility among females.
4. India
⢠Major public health problem in India
⢠During the serological survey of syphilis, about 19,808 cases reported in the year
2017.
⢠Gonorrhoea more widely than syphilis and about 59,266 cases reported in the year
2017.
⢠LGV and Donovanosis more common in southern states of Tamil Nadu , Andhra
Pradesh, Karnataka
5. Epidemiological determinants
⢠Agent factors
Pathogen Diseases or syndrome
Neisseria Gonorrhoea Gonorrhea,urethritis,cervicitis,epididymitis,salpingitis,
PID,neonatal conjunctivitis
Treponema pallidum Syphilis
Hemophilus Ducreyi Chancroid
Chlamydia Trachomatis LGV, urethritis, cervicitis,
proctitis,epididymitis,infant pneumonia
Calymmatobacterium granulomatis Donovanosis (Granuloma inguale)
Herpes simplex virus Genital Herpes
Hepatitis B virus Acute and chronic hepatitis
Human Papilloma Virus Genital and anal wart
Human Immunodeficiency Virus AIDS
Molluscum Contagiosum Genital Molluscum Contagiosum
Candida Albicans Vaginitis
Trichomonas Vaginalis Vaginitis
6. Host factors
1. Age : more common in 20-24 years followed by 25-29 . Most common
morbidity is observed during foetal development and in the neonate.
2. Sex- higher in Men than women but severity is more in women.
3. Marital status: frequency is higher among single,divorced and separated persons
than among married.
4. Socio economic status: from low socio economic groups have highest morbidity
rate
7. Demographic factors:
1. Population explosion
2. Marked increase in the number of young peopleâ
3. Rural to urban migration.
4. Increasing educational opportunities for women delaying their marriage
8. 1.Prostitution : major factor in the spread of STDs. Act as reservoir of infection
2. Broken Homes : Promiscus women are usually drawn from broken homes .homes which are usually broken
either due to death of one or both parents or their separation. The atmosphere in such homes is unhappy and
children reared in such an atmosphere are likely to go stray in search of other avenues of Happiness.
3. Sexual disharmony : married people with strained relations, divorced and separated persons are often
victims.
4. Easy Money : Prostitution is reflection of poverty. Occupation for earning easy money.
5. Urbanization and industrialization : long working hours, relative isolation from family.
6.Social disruptions: caused by disasters,wars,civil unrest.
7. Changing behavioural patterns.
8. Social stigma. 9.Alcohol
Social factors
9. Vulnerable groups for STI â High Risk groups
⢠In certain group of individual the incidence and Prevalence of the STIs are
generally more than a normal population, they are called as âCore Groupsâ.
⢠Includes :-
ď§ Commercial Sex workers (CSW)
ď§ Injecting Drug Users and their partners
ď§ Prisoners
ď§ Street Children
ď§ Group of individuals who are client to CSWs like long distance truck drivers,
tourists/travellers
10. Clinical Spectrum
⢠STDâs of Concern
â˘
Actually, all of them
⢠âSoresâ (ulcers)
⢠Syphilis
⢠Genital herpes (HSV-2, HSV-1)
⢠Others uncommon in the U.S.
⢠Lymphogranuloma venereum
⢠Chancroid
⢠Granuloma inguinale
⢠âDripsâ (discharges)
⢠Gonorrhoea
⢠Chlamydia
⢠Nongonococcal urethritis / mucopurulent cervicitis
⢠Trichomonas vaginitis / urethritis
⢠Candidiasis (vulvovaginal, less problems in men)
Other major concerns
Genital HPV (especially type
16, 18)
Cervical Cancer
12. Prevention and Control
⢠Main components of STI control :
1. Elimination of reservoirs
2. Breaking the chain of Transmission.
3. Protection of the susceptible.
4. Other measures
13. 1. Elimination of reservoir
⢠Main emphasis: detection and control of infection in core group members.
1. Case detection :early detection is backbone.
2. Screening :
⢠STI show ice berg phenomena: selective screening for core group population and
opportunistic screening for at risk.
⢠Screening for antenatal mothers and blood donors also.
3. Contact tracing :
⢠Tracing the sexual partners by rapid means before incubation period.
⢠After identification, counselling to be done for- STI clinic visit, examination and
treatment.
14. 4. Cluster testing :
⢠Testing of those who reside in the same socio sexual environment of any diagnosed STI
cases.
⢠Most effective way of identification of CSWs, Homosexuals-if confidentiality is
maintained.
5. Case holding and Treatment :
Administration of Full course of treatment to all the contacts or to recently exposed people
before getting investigations results referred as â Epidemiological Treatment or Contact
Treatment
Follow up is mandatory
Incomplete treatment and drop out result in anti microbial
resistance
After identification of case , by screening procedure
Provide complete treatment with confidentiality
15. 2. Breaking the chain of Transmission
⢠Abstinence â absolute and impractical method
⢠Safe sex practice with barrier method.
3. Protection of the susceptible
Safe sex to be practice in the community.
⢠Faithful to one sexual partner
⢠Using barrier method- correct & consistent use
16. 4. Other measures :
1. Health education : changes behaviour to minimize the disease acquisition & spread.
2. Vaccination : Only Hep B vaccine available for Control
3. STI clinics / Suraksha Clinic :
⢠Delivers sexual & reproductive health services
⢠NACO âthrough its network establishes STI/RTI clinics (at Govt Facility at district level
and above) , provides free standardized STI/RTI services.
⢠Treatment is as per syndromic management approach.

⢠Free counselling services to patient and their partners by trained counsellors.
17. Treponema pallidum â The Agent of Syphilis
⢠Spirochete
⢠Obligate human parasite
⢠Transmission:-Sexual,Trans-placental,Percutaneous following contact with infectious
lesions, Blood Transfusion
⢠Incubation Period â 21 days (median)
⢠3 clinical stages of syphilis
â Primary:
â˘Painless sore (chancre) at inoculation site
â Secondary:
⢠Rash, Fever, Lymphadenopathy, Malaise
â Tertiary/Latent:
⢠CNS invasion, organ damage

â Early: macule/papule erodes
â Late: clean based, painless, indurated ulcer with smooth firm borders
⢠Unnoticed in 15-30% of patients
⢠Resolves in 1-5 weeks
⢠HIGHLY INFECTIOUS
⢠Primary Syphilis Chancre
⢠Represents haematogenous dissemination of spirochetes
⢠Usually 2-8 weeks after chancre appears
⢠Findings:
⢠rash - whole body (includes palms/soles)
⢠mucous patches
⢠Condylomata lata - HIGHLY INFECTIOUS
⢠constitutional symptoms
⢠Sn/Sx resolve in 2-10 weeks
19. Congenital Syphilis
⢠Congenital syphilis usually
occurs following vertical
transmission of T. pallidum
from the infected mother to
the fetus in utero, but neonates
may also be infected during
passage through the infected
birth canal at delivery.
20. DIAGNOSIS OF SYPHILIS
1. History and clinical examination.
2. Dark-field microscopy: special technique use to demonstrate the spirochete as
shiny motile spiral structures with a dark background.
⢠The specimen includes oozing from the lesion or sometimes L.N. aspirate. It is
usually positive in the primary and secondary stages and it is most useful in the
primary stage when the serological tests are still negative.
⢠Laboratory Testing
⢠Direct examination of clinical specimen by dark-field microscopy or fluorescent
antibody testing of sample.
⢠Non-specific or non-treponemal serological test to detect reagin, utilized as
screening test only.
⢠Specific Treponemal antibody tests are used as a confirmatory test for a positive
reagin test.

contact.
32. Lymph Granuloma Venereum
⢠Lymph granuloma venereum (LGV) is caused by C. trachomatis serovars L1, L2,
or L3 .
⢠Most common clinical manifestation of LGV among heterosexuals is tender
inguinal and/or femoral lymphadenopathy that is typically unilateral.
33. Trichomoniasis
Occurs in vagina of women so may be sexually transmitted to men using infected wash cloths and
towels.
