Public Health Importance of RTIs/STIs
What is RTI/STI ?
Reproductive Tract Infections (RTIs):
Any infection of reproductive tract in male and female
Sexually Transmitted Infections (STIs):
STIs are infections caused by germs such as bacteria, viruses,
or protozoa that are passed from one person to another
through sexual contact.
RTIs
RTIs in both men and women include:
- STIs
RTIs in women also include:
- Disruption of normal vaginal flora (Candida and bacterial vaginosis)
- Postpartum and post abortion infections
- Infections following procedures (e.g. IUD insertion)
RTIs in men also include:
- Prostatitis and epididymitis
Situation in world
340 million new cases of curative STIs every year
- 75-85% in developing countries
- 10 % adults newly infected with curable STIs
12 million new cases of syphilis
62 million new cases of gonorrhoea
90 million new cases of chlamydia
176 million new cases of trichomonas
Situation in India
Prevalence of suggestive symptoms of STIs
Women: 23-43%
Men: 4-9%
STI clinic data for men indicates:
Syphilis: 12.6 – 57%
Chlamydia: 20-30%
Chancroid: 9.9 -34.7%
Gonorrhoea: 8.5 – 23.9%
Overall prevalence of STIs among adults: 6 %
Factor contributing to RTI/STI spread
Human behaviour
Lack of access to healthcare
Lack of awareness about STIs
Migrating population
Healthcare providers not adequately trained
Poor medical services
Hygiene and environmental factors
Hormonal and other factors
High risk groups
Adolescent boys and girls
Women who have multiple partners
Sex workers and their clients
Men and women who has to stay away from families for long
Men having sex with men
Partners of various high risk groups
Street children
Factors increasing risk of transmission
Biological
- Age
- Sex
- Immune status
Behavioural
- Personal sexual behaviour
- Other non-sexual personal behaviour
- Even without any risk behaviour
Social
- Status of women in society
- Sexual violence
- Child marriages
Why women are at a higher risk?
Biological differences
-Thin lining of vaginal mucosa
- Larger exposed area
- Genital fluids stay in contact for longer time
- Young women- Immature genital tract
- Symptoms less reliable indicator
Use of vaginal douches
Different socio-cultural norms for men and women
STI – HIV Link
RTIs/STIs – A Public Health Problem

Increases risk of HIV transmission
Responsible for reproductive loss
Increases cost to health system
Barriers – system and providers side
Failure to recognize magnitude
Not all seek treatment form trained providers
Overemphasis on lab based diagnosis

Module 4
Approaches for RTI/STI
Management
RTI/STI Case Management
Correctly diagnosing and treating symptomatic patients.
Providing patient education and partner management.
Preventing re-infection
Steps in Clinical Case Management
History taking
Clinical examination
Laboratory tests
Diagnosis
Treatment
Advice and counseling
Follow up
Approaches to RTI/STI Case Management
Traditional clinical approach
Laboratory assisted approach
Syndromic approach
Traditional Clinical Approaches:
Advantages
Simple
Inexpensive
Can be used in any settings
Immediate diagnosis.
Immediate treatment.
No lab expense.
Traditional Clinical Approach :
Limitations
Diagnosis is often incorrect or incomplete
(especially in mixed infections).
More than one STI is often present at the same timefocus is on diagnosing a single cause.
Asymptomatic infections could not be diagnosed.
Lab-Assisted Approach
Advantages
Exact diagnosis using laboratory tests.
Avoids over-treatment.
Avoids wrong treatment.
May avoid antibiotic resistance.
Avoids the negative consequences
Asymptomatic infections can also be detected.
Lab-Assisted Approach
Limitations
Expensive.
Trained laboratory technicians are needed.
Infrastructure and supplies are needed.
Patient must return for test results.
Patient must wait for treatment.
Syndromic Approach
Diagnosis is based on the identification of syndromes,
which are combinations of the symptoms the client reports
and the signs the health care provider observes.
The provision of the most effective therapy at patient’s first
contact with a health or medical facility.
The recommended treatments are effective for all the
diseases that could cause the identified syndrome.
Provides single dose treatment as far as possible
Comprehensive to include patient education on risk
reduction, counseling, condom promotion and
provision, partner notification, follow up.
Syndromic Management- Advantages
Fast—the patient is diagnosed and treated in one visit.
Highly effective for most of the syndromes.
Relatively inexpensive since it avoids use of laboratory.
No need for patient to return for lab results.
All possible STIs are treated at once.
Scientifically tested in many part of the world.
Easy for health workers to learn and practice for patients.
Integrated into primary health care services more easily.
Can be used by providers at all levels.
Syndromic Management- Limitations
Not useful in asymptomatic individuals.
Over-treatment in patient with one STI that causes a syndrome.
Financial cost of over-treatment, side- effects.
Increases potential for antibiotic resistance especially if full
course not completed.
Not effective in some cases such as vaginal discharge
The Syndromes
Urethral discharge
Vaginal discharge
Genital ulcer non-herpetic
Genital ulcer herpetic
Lower abdominal pain
Inguinal bubo
Scrotal swelling
To sum up ………
Syndromic management is a scientific and proven approach.
Syndromic approach does not deny use of lab tests, it can
supplement the approach (Enhanced syndromic approach).
This approach ensures correct and complete treatment of all
most common organisms responsible for a particular syndrome.
Syndromic management goes beyond pharmaceutical treatment
to include client education and counseling.
The clinical skills of a doctor are well utilized in syndromic
approach.
Module 4
Syndromic Management
Flowcharts
Using Flow Charts
Determine the clinical problem
Pick up appropriate flow chart by looking at the clinical problem
box at the top
Take history
Perform clinical examination
Make decisions based on history and clinical examination –
choosing “yes” or “no”
Followed by more boxes to consider and make choices
Follow the arrows
No skipping of steps
One step at a time until you reach the end of the branch
Each exit path leads to action box - how to manage the case
Man complains of scrotal swelling and
pain
Take history & examine
Painful scrotal swelling confirmed
Testes rotated/ elevated
or history of trauma
Refer immediately for a
surgical opinion
Testes normal. No history of
trauma
Treatment for Gonorrhoea and
Chlamydia.
Patient Education, counselling
Provide and promote condom
Partner management
Cured
Return in 7 days if
symptoms persist
No improvement
Refer to higher care center
Why Syndromic Management?
Simple
Treatment at first visit
Treatment for all common causative organisms
Standardized at all sites
Patient education, an integral part
Criteria for Selection of Drugs
High efficacy (at least 95%)
Low cost
Acceptable toxicity and tolerance
Organism resistance unlikely to develop or likely to be
delayed
Single dose
Oral administration
Not contraindicated for pregnant or lactating women
To sum up ……………..
The drugs use in syndromic management are chosen based
on scientific criteria
Syndromic management is a comprehensive approach which
includes:
Treatment of index client
Treatment of partners
Risk reduction
Client education and counseling
Referral, as necessary
Module 6
History Taking and Risk
Assessment
Goals of history taking for RTIs/STIs
Make an accurate and efficient syndromic diagnosis
Establish the client’s risk of transmitting and contracting
RTIs/STIs
Find out about partners who may have been infected
Pre-requisites for good history taking
Privacy
Confidentiality
Good verbal and non-verbal communication skills
Unbiased/non-judgmental attitude of provider
Patient- friendly atmosphere
Sexual history
Currently active sexually
Current partners
New partners in last 3 months
Risky sexual and other behaviour
Risk assessment
Risk assessment is a process of confidentially asking a
patient particular questions to determine his or her chance of
contracting or transmitting a RTI/STI (e.g. many women may
be at risk due to the behavior of their husbands or partners).
Why risk assessment?
To determine RTI/STI treatment
To tailor patient education messages
Determine need for lab test
Determine need for specific referrals (ICTC)
Module 7
Clinical Examination in
RTI/STI Clients
Why clinical examination is important?
Confirmation of client’s symptoms
Elicit signs to confirm symptoms
Find out signs for something the patient is not complaining
To arrive at a clinical dignosis
Pre-requisites for clinical examination
Visual and auditory privacy
Assistant of same sex that of client, if examining opposite sex
Explain process to client (with pictorials/diagram)
Take permission from client
Well lit room
Approach in a confident manner
Male Syndromes
Inguinal Bubo
Genital Ulcer
Scrotal Swelling
Genital Ulcer
Vaginal Discharge Syndrome
SYNDROME: VAGINAL DISCHARGE
VAGINITIS
TRICHOMONIASIS
CERVICAL HERPES
CERVICITIS
Module 8
Laboratory Tests for
RTIs/STIs
Use of Lab in RTI/STI Control
Screening and detection
Screening asymptomatic in high risk population
To diagnose single and mixed infections
Improve diagnostic value of syndromic management
Detection of infection in asymptomatic
Epidemiological data – prevalence, incidence
Testing for antimicrobial resistance
Sentinel surveillance
Accurate etiological diagnosis
Diagnostic tests for RTIs/STIs
Microscopic examination:
-Wet mount: Trichomoniasis, candida, bacterial vaginosis
- Gram staining: Gonorrhoea, Bacterial vaginosis
- Dark field: Syphilis
Antigen detection: EIA for gonorrhoea and chlamydia
Antibody test: EIA for Syphilis and HIV
Vaginal pH : Bacterial vaginosis
Culture: Trichomonous, Candida albicans, Chlamydia
DNA detection
DNA detection by amplified technique
Lab tests for detection of common
RTIs/STIs
Vaginal pH
Wet mount microscopy
Whiff test
Gram stain microscopy
Rapid Plasma Reagine (RPR) for syphilis
Limitations of laboratory tests
Costly
Time consuming
Need trained manpower
Need expensive equipment
Delay in diagnosis and treatment
Not all tests are high sensitivity and/or specificity
We must remember …….
Some simple lab tests can assist us enhancing the
effectiveness of syndromic management.
The doctors are expected to interpret the results of lab tests.
Do not delay the syndromic treatment for the sake of
laboratory results.
Lab tests can be useful for specific diagnosis of the infections
and for collecting epidemiological data.
Module 9
Client Education and
Counseling
Importance of Client Education and
Counseling
Better compliance to treatment if clients know the
logic/reasons
To reduce chance of re-infection
To enable clients change behavior
Satisfied clients return for other services too
Satisfied clients refer others to health center
Goals of Client Education
Help clients resolve current infection
Prevent future infections
Make sure sex partners are also treated and educated.
What Clients Needs to Know
Prevention of RTIs/STIs
- Risk reduction
- Correctly and consistent use of condoms, availability
- Limiting the number of partners
- Alternatives to penetrative sex
Information about RTIs/STIs
- How they are spread between people
- Consequences of RTIs/STIs
- Links between RTIs/STIs and HIV
- RTI/STI symptoms - what to look for
What Clients Needs to Know
RTI/STI Treatment
- How to take medications
- Signs that call for a return visit to the clinic
- Importance of partner referral and treatment
- Acknowledge gender inequalities
Cont…
Creating Opportunities for Client Education
Use every place where client is likely to visit
Use every interaction as an opportunity
Use various media
Reinforce consistent messages
Module 10
Partner Management
What is Partner Management ?
Partner management is an activity in which the partners of
those identified as having RTI/STI are located, informed of
their potential risk of infection, and offered treatment and
counseling services.
Timely management is important
because……..
Prevention of re-infection in index client/s
Prevention of transmission in partner/s
Timely treatment of symptomatic partners
Identification of asymptomatic partners and their treatment
Approaches to Partner Management
Referral by index clients:
- Index clients inform partners
- Does not involve extra person hence inexpensive
- May include client-initiated therapy
Referral by providers:
- Providers approach partner/s through referral card
- Needs extra staff and hence expensive
General principles of partner treatment
Partners to be treated for same infections as index client.
Provider should be reasonably sure of presence of STI,
especially in vaginal discharge cases.
Special care for PID cases due to serious complication.
Call for follow up – for compliance/cure and to see test
reports, if advised
