all states allow minors to consent for their own STI services, and no state requires parental consent for STI care
Due to biological and behavioral factors, adolescents are at high risk for STIs and their serious long-term consequences if left undiagnosed or untreated
adolescent female columnar epithelial cells are more exposed and vulnerable to STIs (ex: chlamydia and gonorrhea) since the cells cover the vaginal side of the cervix (external os/orifice) where they are unprotected by cervical mucus
with age, these cells move to a more protected position
High-risk factors: sex in early to middle adolescence, alcohol & substance use, male to male sex, detention center living, mood disorders, adverse childhood experiences (ex: maltreatment, sexual abuse), multiple or new sex partners or a partner with multiple partners and not using condoms
Inexperience with condoms
do not store at a hot temp
hold condom while withdrawing
Untreated STI → PID → infertility, adverse pregnancy outcomes, anogenital & cervical cancers
Having other STIs raises the risk of transmitting and acquiring HIV, as skin breaks make it easier for the virus to enter the body
All states recognize chlamydia, gonorrhea, syphilis, chancroid, and HIV as notifiable conditions
federal law mandates HCP to report new cases of these to public health authorities
Proper external condom use:
Use latex or polyurethane condoms
Polyurethane: more expensive, thinner, looser fit, breaks more often
just as effective as latex
not compatible with all the different kinds of lubricants (water, silicone, silicone hybrid, oil) so check each lubricant brand for compatibility
Ensure storage in a cool, dry place away from direct sunlight
no wallet, automobile, or anywhere it could be exposed to extreme temps
Check expiration date
Open carefully, no sharp objects
Do not use if it appears brittle, sticky, or discolored (signs of aging)
Put condom on before any genital contact (sperm is present in pre-ejaculate fluid)
Put condom on and withdraw after sex when penis is erect
Ensure it is placed so it will readily unroll; hold the tip of the condom while unrolling
Ensure there is a space at the tip for semen to collect, but make sure no air is trapped in the tip (pinch air out)
Ensure adequate lubrication during intercourse
use only water-based lubricants (K-Y Jelly) with latex condoms.
Oil-based or petroleum-based lubricants (body lotion, massage oil, cooking oil) weakens latex condoms
Proper internal condom use:
Do not use an external condom with an internal condom.
thick inner ring with the closed end goes into the vagina (similar to inserting a tampon); the thin outer ring remains outside the body
Ensure condom is not twisted, and that the outer ring does not get pushed into the vagina
Perceived Barrier | Intervention Strategy |
Decreases sexual pleasure (sensation) |
|
Decreases spontaneity of sexual activity |
|
Requires prompt withdrawal after ejaculation |
|
Fear of breakage may lead to less vigorous sexual activity |
|
Allergy to latex |

Vaginitis: inflammation and infection of the vagina
causes: more often than not, by one of three organisms:
Candida, a fungus
Trichomonas, a protozoan
Gardnerella, a bacterium
Genital/vulvovaginal candidiasis (VVC):
one of the most common causes of vaginal discharge
also referred to as yeast, monilia, and fungal infection
NOT considered an STI because Candida is a normal constituent in the vagina and becomes pathologic only when the vaginal environment is altered
Treatment medications:
Miconazole (Monistat) - vaginal cream or suppository (OTC)
Clotrimazole (Gyne-Lotrimin) - vaginal tablet or cream (OTC)
Tioconazole (Monistat-1; Vagistat-1) - vaginal tablet or cream (OTC), single dose
Terconazole - vaginal ointment
Butoconazole (Gynazole-1) - vaginal cream, single dose
Fluconazole (Diflucan) - 150 mg oral tablet, usually 1 but possibly 2 doses
Ibrexafungerp (Brexafemme) - 150 mg oral tablet, two tabs given twice in 1 day; used in nonpregnant patients who cannot use fluconazole
Topical azole preparations are an effective treatment
untreated VVC during pregnancy → newborn oral thrush during birth, must be treated with a local azole preparation after birth
predisposing factors:
Pregnancy
oral contraceptives with high estrogen content
broad-spectrum antibiotics, steroid and immunosuppressive drugs
DM, obesity
HIV infection
Wearing tight, restrictive clothes and nylon underpants
Trauma to vaginal mucosa from chemical irritants or douching
Typical symptoms, which can worsen just before menses, include:
Pruritus (itching)
Vaginal discharge (thick, white, curdlike)
Vaginal soreness
Vulvar burning
Erythema in the vulvovaginal area
Dyspareunia
External dysuria (felt at the outer opening of the genital area)
Speculum examination will reveal white plaques on the vaginal walls
Definitive diagnosis is made by a wet smear, which reveals the fungal characteristic when viewed under microscope
preventive measures:
Avoid douching
Use condoms, limit sex partners
Urinate with knees spread wide apart.
Gently wash and dry the vulva with mild, unscented bar soap, avoiding liquid soaps and body washes.
Avoid powders, bubble baths, and perfumed vaginal sprays.
Change out of wet bathing suits ASAP
Reduce dietary intake of simple sugars and soda.
Wash underwear in hot water with unscented detergent and dry on high heat to kill yeast
Avoid the use of superabsorbent tampons (use pads instead).
a flagellated protozoan that is a common parasite found in all sexes
mainly sexually transmitted, but can also live on damp/wet surfaces (poorly cleaned/maintained hot tubs, drains, towels, bathing suits)
females may or may not be symptomatic, males are often asymptomatic
can cause preterm birth, PROM, low-birth-weight infants, PID, infertility
infection doubles the risk of HIV susceptibility
it IS an STI but is NOT nationally reportable
single 2g oral dose of metronidazole (Flagyl), tinidazole (Tindamax), or secnidazole
for both partners
preferred treatment in females using metronidazole: multidose therapy, 500mg BID for 5-7 days
clinical manifestations:
heavy yellow/green, grayish frothy, or bubbly discharge
Vaginal pruritus and vulvar soreness; vaginal or vulvar erythema
Lower abdominal pain
Dyspareunia
A cervix that may bleed on contact
Dysuria
Foul vaginal odor
Petechiae on the cervix (“strawberry cervix”)
confirming diagnosis:
nucleic acid amplification tests (NAATs) are highly accurate with sensitivity and specificity near 100%
Evaluation of vaginal pH and microscopy, where a motile flagellated trichomonad is visualized under the microscope, are are faster and more convenient but also less accurate
vaginal pH >4.5 is a typical finding
Instruct both patients to avoid sex until BOTH are cured (completed therapy & symptom-free)
Follow-up testing is not indicated if symptoms resolve with treatment
results from a shift in the balance of the vaginal microflora
cause: new or multiple sex partners, douching, not using condoms
most prevalent cause of vaginal discharge or malodor
most are asymptomatic
IS an STI
bacterial imbalance is associated with sexual contact but is not usually spread through sex
an associated inflammatory response is lacking
can cause preterm labor, high risk of contracting HIV and other STIs, low birth weight, endometritis, and PID
Treatment: indicated for confirmed symptomatic BV patients or those having a gynecologic procedure involving the vagina
oral or vaginal metronidazole (Flagyl), clindamycin (Cleocin) cream
Treatment of the male sex partner is not indicated, however it can spread between female sex partners
Assess for clinical manifestations
primary symptoms: thin white/grayish homogeneous vaginal discharge, pain, itching & burning in or around the vagina, burning when urinating, and a characteristic “stale fish” odor often recognized only after sexual intercourse
diagnosis in which ¾ of the following four criteria must be met:
Thin, white/grayish vaginal discharge that adheres to the vaginal mucosa
Vaginal pH >4.5
Positive “whiff test” (secretion is mixed with a drop of 10% potassium hydroxide on a slide, producing a characteristic stale fishy odor)
presence of clue cells on wet-mount examination
primary prevention and education to limit recurrences
high risk behaviors: recent antibiotic use, douching, sexual activity with multiple partners, not using condoms
reinforce importance of following medication instructions and finishing the entire course of prescribed antibiotics
Cervicitis: inflammation or infection of the cervix
Ranges from symptomless erosions to an inflamed, bleeding cervix (on contact) with abnormal discharge containing unusual organisms
usually caused by gonorrhea or chlamydia, as well as almost any pathogenic bacterial agent and a number of viruses
highest incidence: young females aged 15-24 years & HIV-positive females
treatment: targeted therapy for the specific organism causing it
preventative measures: the ABC (abstinence, being monogamous, condom use) strategy
cause by Chlamydia trachomatis (bacterium)
intracellular parasite, cannot produce its own energy, depends on the host for survival
often difficult to detect
long-term consequences if left untreated
most common risk factors: young age, history of a previous chlamydia infection, new sex partner or multiple sex partners in the past 3 months, lack of barrier contraception use, disadvantaged socioeconomic conditions, Black females
being asymptomatic is common among both males and females
untreated females → cervicitis, urethritis, PID → infertility, chronic pelvic pain, ectopic pregnancies
also increases the risk of transmitting the infection to partners
untreated in pregnancy → PROM, preterm labor, and low-birth-weight newborns
Newborns of infected moms may develop ophthalmia neonatorum, an acute conjunctivitis in the first month of birth
CDC recommendation: yearly testing of all sexually active or pregnant females ages 25 and younger, as well as older or pregnant females with risk factors
diagnosis: nucleic acid amplification tests (NAATs) on the cervical or vaginal swabs and urine samples
Antibiotics (patient AND partner)
doxycycline (preferred treatment) 100mg PO BID for 7 days
if doxycycline is contraindicated, like in pregnancy, use azithromycin (Zithromax) 1g PO single dose
Retesting in 3 months to identify reinfection is suggested
confirmed patients should be tested and treated for other STIs
significant risk factors:
age <24
multiple sex partners, new sex partner
unprotected vaginal, anal, or oral sex
oral contraceptive use
HIV-positive
Being pregnant
history of another STI
majority of females are asymptomatic
clinical manifestations (if symptomatic):
Mucopurulent vaginal discharge (a combination of mucus and pus)
Urethritis
Bartholinitis
infection & inflammation of the Bartholin's glands (located on either side of the vaginal opening producing mucus for lubrication)
Endometritis
Salpingitis
inflammation of one or both fallopian tubes due to an infection
a type of PID
Dysfunctional uterine bleeding
treatment strategies, referral sources, and preventive measures
Provide education about risk factors
Emphasize the importance of seeking treatment, adhering to prescribed treatment regimens, informing sex partners, and receiving any recommended follow-up testing
Stress that both of these STIs can lead to infertility and long-term sequelae
a severe bacterial infection that can occur in the genitals, rectum, or throat
cause: N. gonorrhoeae
site of infection is the columnar epithelium of the endocervix (the cervical canal between the internal and external os)
STI, almost exclusively transmitted by sexual activity
association during pregnancy: chorioamnionitis, premature labor, spontaneous abortion, PROM, and low-birth-weight or small-for-gestational-age infants
can also be transmitted to the newborn as ophthalmia neonatorum by direct contact during vaginal birth
highly contagious
untreated → blindness, corneal ulceration
increases the risk of PID, infertility, ectopic pregnancy, chronic pelvic pain, other STIs, HIV acquisition and transmission
can be difficult to cure due to antibiotic resistance
asymptomatic common among females
major factor in the spread of it
CDC recommends yearly testing for all sexually active or pregnant females ages 25 and younger, as well as older or pregnant females with risk factors
pregnant patients should be screened during the 1st trimester and again in the 3rd trimester if at high risk for STIs
Nucleic acid hybridization tests (GenProbe) are used for diagnosis
spreads upward: endocervix → uterine endometrium → fallopian tubes → peritoneal cavity
peritoneum and ovary involvement = PID
untreated → enters bloodstream → disseminated (widespread) gonococcal infection
can invade the joints (arthritis), the heart (endocarditis), the brain (meningitis), and the liver (toxic hepatitis)
treatment of choice: single IM high dose of ceftriaxone (Rocephin) 500mg for pregnant and nonpregnant females weighing less than 150kg (330lbs)
If chlamydia has not been ruled out, proper treatment for chlamydia should be started
Retesting in 3 months to identify reinfection is suggested
ophthalmia neonatorum prevention: prophylactic agent (erythromycin ointment or azithromycin solution) instilled into the newborns eyes
risk factors: low education level, low socioeconomic status, single status, inconsistent use of barrier contraceptives, age under 25 years, being of an underrepresented ethnic population, substance misuse, history of previous gonorrhea, having a new sex partner, having multiple sex partners
involves taking a health history that includes a comprehensive sexual history
most females are asymptomatic
Assess for clinical manifestations:
Mucopurulent vaginal discharge
Dysuria
Dyspareunia
Abnormal vaginal bleeding
Bartholin abscess
painful infection that develops when a Bartholin gland cyst becomes infected, leading to a buildup of pus
Abdominal or pelvic pain
treatment strategies, referral sources, and preventive measures
Provide education about risk factors
Emphasize the importance of seeking treatment, adhering to prescribed treatment regimens, informing sex partners, and receiving any recommended follow-up testing
Stress that both of these STIs can lead to infertility and long-term sequelae
Genital herpes & syphilis have been associated with an increased risk of HIV infection
Not all genital ulcers are caused by STIs
a recurrent, lifelong viral infection that has the potential for transmission throughout the lifespan
once infected, they remain infected for life
characterized by painful, recurrent outbreaks of genital and anal lesions
Infection during pregnancy → neonatal herpes disease, spontaneous abortion, preterm labor
Two serotypes of HSV have been identified: HSV-1 and HSV-2
HSV-1: oral herpes (cold sores, fever blisters)
most infections are acquired during childhood
HSV-2: genital herpes; both types can cause outbreaks in either location.
transmitted via direct mucous membrane contact or breaks in the skin
females are infected twice as much as males, partly due to prolonged exposure to semen during vaginal intercourse
kissing, sex (including oral), vaginal delivery
Many have mild or unrecognized infections but still shed the herpes virus intermittently
happens in this order: primary outbreak → virus remains dormant in the nerve cells for a lifetime → periodic recurrent outbreaks
Immunocompromised people = more frequent & severe recurrent outbreaks
Potential psychosocial consequences: emotional distress, isolation, fear of rejection, depression, fear of transmission, altered perceptions of self-esteem
No cure exists
antiviral drug therapy helps suppress symptoms, shedding, and recurrent episodes
treatment: acyclovir (Zovirax) 400mg PO TID for 7-10 days, famciclovir (Famvir) 250 mg PO TID for 7-10 days, or valacyclovir (Valtrex) 1g PO BID for 7-10 days
Assess for clinical manifestations (primary and recurrent episodes)
first/primary episode: most severe, viral shedding process takes up to 2 weeks to complete
systemic disease characterized by multiple painful vesicular lesions, mucopurulent discharge, superinfection with candida, fever, chills, malaise, dysuria, headache, genital irritation, inguinal tenderness, lymphadenopathy
lesions are frequently located on the vulva, vagina, and perineal areas
vesicles open and finally crust over, dry, and disappear without scar formation
recurrent episodes: milder, fewer lesions, shorter in duration
may occur 5-8x per year
Tingling, itching, pain, unilateral genital lesions, and a more rapid resolution of lesions
a localized disease
Diagnosis: viral culture or polymerase chain reaction (PCR) (preferred diagnostic tests), based on clinical s&s
Therapeutic management: counseling regarding the natural history of the disease, the risk of sexual and perinatal transmission, current treatment regimens, and the use of methods to prevent further spread
Referral to a support group
Address psychosocial aspects of these STIs by discussing appropriate coping skills, acceptance of the lifelong nature of the condition (herpes), and options for treatment and rehab
a systemic, curable bacterial infection caused by the spirochete Treponema pallidum
untreated → disability, death, hepatitis, CV issues, CNS damage
episodes of active clinical disease are punctuated with periods of latency.
Enters the lymph and bloodstream → systemic infection before any primary lesion appears
site of entry may be vaginal, rectal, or oral
Congenital syphilis can occur via transplacental transmission (virus can cross the placenta) or direct contact during birth
can cause spontaneous abortion, low birth weight, prematurity, stillbirth, and multisystem problems of the bones, liver, pancreas, intestine, kidney, and spleen
All pregnant patients should be screened at the first prenatal visit, with repeat testing at 28 weeks and before delivery for high-risk patients
Screen patients without symptoms who are considered high risk
injection of penicillin G can cure primary, secondary, or early latent syphilis
late latent syphilis: 3 doses at weekly intervals
Pregnant people should be treated with the same regimen for whichever stage they present with
give doxycycline if there’s a penicillin allergy
reevaluated at 6 &12 months after treatment for primary or secondary syphilis with additional serologic testing
Patients with latent syphilis should be followed up with clinically and serologically at 6, 12, and 24 months
has many nonspecific s&s
Assess for clinical manifestations
untreated → 5-stage lifelong infection progressing in order (primary, secondary, early latent, late latent, tertiary)
primary, secondary, and early latent stages being considered the most infectious (see below)
Primary stage: presents as a chancre (painless ulcer) at the site of bacterial entry that will disappear within 3-6 weeks without intervention
painless bilateral adenopathy (swollen, enlarged lymph nodes)
Secondary stage: appears 2-6 months after initial exposure, lasts about 2 years
manifestations: flulike symptoms (see below), a rash of the trunk, palms & soles, alopecia, adenopathy swollen, enlarged lymph nodes)
fever, sore throat, weight loss, myalgias, and fatigue
early and late latent stages: no s&s, though serology is positive
can last as long as 20 years
tertiary or late stages: life-threatening CV syphilis, gumma syphilis, and CNS syphilis
slowly destroys the heart and inflames the aorta, eyes, brain, CNS, and skin
Serologic testing is evaluated using both nontreponemal and treponemal tests
Nontreponemal tests: measure IgM and IgG
most commonly used: the rapid plasma regain (RPR) & Venereal Disease Research Laboratory (VDRL)
less specific but commonly used for primary screening because they’re performed rapidly and inexpensive
Treponemal tests: detect treponema-specific IgA, IgM, and IgG antibodies
greater accuracy
preferred test: T. pallidum enzyme immunoassay
Therapeutic management: counseling regarding the natural history of the disease, the risk of sexual and perinatal transmission, current treatment regimens, and the use of methods to prevent further spread
Referral to a support group
Address psychosocial aspects of these STIs by discussing appropriate coping skills, acceptance of the lifelong nature of the condition (herpes), and options for treatment and rehab
a spectrum of inflammatory disorders usually caused by an ascending infection of the genital tract from chlamydia or gonorrhea
an inflammatory state of the upper female genital tract and nearby structures
encompasses a broad category of diseases, including endometritis, salpingitis, salpingo-oophoritis, tubo-ovarian abscess, and pelvic peritonitis
Long-term complications: ectopic pregnancies, infertility, chronic pelvic pain
common risk factors: age <25, multiple sex partners, insertion of an IUD within the past 3 weeks, history of STIs in the patient or their partner, lack of barrier contraceptive use, previous episode of PID
treatment will be outpatient or inpatient based on clinical judgment and symptom severity
Treatment: IV antibiotics, increased oral fluids to improve hydration, bed rest, and pain management
Broad-spectrum antibiotic therapy required for chlamydia, gonorrhea, or any anaerobic infection
ceftriaxone 1g IV once daily & doxycycline 100mg PO q12h & metronidazole 500mg PO or IV q12h
cefoxitin 2g IV q6h & doxycycline 100mg PO or IV q12h
cefotetan 2g IV q12h & doxycycline 100mg PO or IV q12h
Follow-up is needed to confirm the infection is gone and to prevent chronic pelvic pain
involves a complete health history and assessment of clinical manifestations, physical examination, and laboratory and diagnostic testing
current and past medical and sexual health history
risk factors:
Adolescence or young adulthood
multiple sex partners
History of PID or STI
intercourse with a partner who has untreated urethritis
Recent insertion of an IUD
Lack of consistent condom use
Lack of contraceptive use
Assess for clinical manifestations
Inspect for presence of fever or vaginal discharge
Palpate abdomen, noting tenderness over the uterus or ovaries
No single test is highly specific or sensitive
criteria for diagnosis in sexually active females:
lower abdominal tenderness
adnexal tenderness (the structures that are adjacent to or near the uterus)
cervical motion tenderness
Additional supportive criteria:
Abnormal cervical or vaginal mucopurulent discharge
temp over 101°F (38.3°C)
N. gonorrhoeae or C. trachomatis infection
Abundant WBC’s on saline vaginal smear
Elevated erythrocyte sedimentation rate (inflammatory process)
Elevated C-reactive protein level (inflammatory process)
maintain hydration via IV fluids if necessary and administer analgesics PRN for pain
Semi-Fowler positioning facilitates pelvic drainage
educate to prevent recurrence
Sexual counseling: practicing safer sex, limit sex partners, consistent use of barrier contraceptives, reconsider IUD use if sexually active with multiple partners, completing course of antibiotics as prescribed
Ask the patient to have their partner go for evaluation and treatment to prevent a repeat infection
use condoms
Discourage routine vaginal douching (may cause bacterial overgrowth)
Encourage regular STI screenings
Emphasize the importance of having each sexual partner receive antibiotic treatment if diagnosed with an STI
responsible for anogenital warts and several cancers (cervical, vaginal, vulvar, oropharyngeal, anal cancers)
Strong evidence has established the link between HPV and cervical cancer
causes genital warts or condylomata (Greek for “warts”)
currently no medical treatment or cure
focuses heavily on prevention through the use of the HPV vaccine, education, and treatment of lesions and warts caused by HPV.
vaccine:
9-valent vaccine is used in the US
recommend for routine administration to 11 & 12 year old children
as young as age 9
females between 11-26 years of age should receive the vaccination series
before 15th birthday = two doses for full protection
after age 15 = three doses for full protection
All are prophylactic
designed primarily for cervical cancer prevention, as well as cervical, vulvar, vaginal, penile, and anal cancers
secondary prevention (if no vaccine): education about receiving regular Pap smears and, for female patients over age 30, including an HPV test
goal of treatment: remove the warts and induce wart-free periods for the patient
remove with a local agent during pregnancy
c-section birth is not indicated to prevent transmission unless the pelvic outlet is obstructed by warts
complete health history, assessment of clinical manifestations, physical examination, and laboratory and diagnostic testing
symptoms: profuse, irritating vaginal discharge, itching, dyspareunia, bleeding after intercourse, “bumps” on their labia that may be painful, friable (easily pulverized or crumbled), and pruritic (itchy)
warts can occur on the external genitalia, cervix, vagina, urethra, anus, and mouth
Physical inspection of the external genitalia is important
Health history, physical examination, and laboratory and diagnostic tests:
Most infections are asymptomatic
Lesions can grow large during pregnancy which affects urination, defecation, mobility, and fetal descent
large lesions exist in clusters and bleed easily
Pap smears are now performed every 3-5 years for low-risk females starting at age 21
an HPV test should follow-up an an ambiguous Pap test
can detect high-risk HPV before visible cervical cell changes occur
positive high-risk type of HPV → patient should be referred for colposcopy (visual exam of the cervix and simple staining solutions) which is sometimes accompanied by a biopsy to confirm cervical abnormality
prevention education, vaccine and screening promotion
only way to prevent HPV is to refrain from any genital contact with another person
latex condom use has been associated with a lower rate of cervical cancer
educate that in most cases there are no s&s
Strongly encourage females ages 9-26 to consider the HPV vaccine
promote the importance of obtaining regular Pap smears for all female patients
patients aged >30: suggest an HPV test
Education and counseling:
Even after genital warts are removed, HPV may remain, and viral shedding may continue.
recurrence of genital warts within the first few months after treatment is common (recurrence, NOT reinfection)
no current vaccine for hepatitis C
Recommended hepatitis B screening includes females at risk and all pregnant people at their first prenatal visit and retesting near delivery for high-risk patients
Recommended hepatitis C screening includes all females 18 years of age and older once in their lifetime
Ectoparasites: parasites that live on the outside of the body (host).
common cause of skin rash and pruritus
Overcrowding, weakened immune systems, global traveling, immigration, delayed diagnosis and treatment, and poor public education contribute to the prevalence of ectoparasites
includes infestations of scabies and pubic lice
Scabies
highly contagious intensely pruritic dermatitis caused by a mite
transmission: direct contact & overcrowded living conditions
Intense itching occurs weeks after the initial infection, especially at night
female mites burrows under skin and deposits eggs, which hatch
causes the appearance of linear burrows between the fingers, on the elbows, in the axillae, buttocks, and genitalia
lesions start as a small papule that reddens, erodes, and sometimes crusts
treatment: topical administration of a scabicidal agent (permethrin, crotamiton, ivermectin) plus an antibiotic if a secondary infection is present
Lice
blood-sucking insects that can be found on people’s heads, bodies, or pubic areas
pediculosis pubis = pubic louse = public lice
s&s: pruritus, because of a rash brought on by skin irritation from scratching, or lice or nits in their pubic hair, axillary hair, abdominal and thigh hair, and sometimes in the eyebrows, eyelashes, and beards
usually asymptomatic until after a week or so, when bites cause pruritus and secondary infections from scratching
Diagnosis: presence of nits (small, shiny, yellow/white, oval, dewdroplike eggs) affixed to hair shafts or lice (a tan to grayish, short, wingless insect that appears crablike)
Treatment: medication (topical antilouse agents) & environmental control measures
Bedding & clothing:
wash in hot water, dry on hot setting in dryer
dry cleaning
seal clothes in plastic bags for 2 weeks to decontaminate them
Sex partners should be treated, as well as family members who live in close contact with the infected person
Nursing care involves a three-tiered approach: eradicating the infestation with medication, removing the nits, and preventing spread or recurrence by managing the environment
HIV targets the immune system and weakens the body’s defense systems against infections and some types of cancer
antiretroviral treatment halts the replication of the virus and ease symptoms, turning AIDS into a manageable chronic condition instead of a rapid terminal illness
AIDS is a breakdown in the immune function caused by HIV, a retrovirus
virus cannot live long outside the human body, cannot be transmitted via tears or sweat
infection is the driving force behind CD4 T-cell depletion and progression to AIDS
infected person develops opportunistic infections or malignancies that become fatal
HIV transmission: sexual intercourse, body secretions, needle sharing/blood exposure, and perinatal transmission
breastfeeding is a method of transmission
Females are more vulnerable to heterosexual transmission due to prolonged exposure to semen
parent-to-child HIV transmission occur late in pregnancy or during delivery
ART therapy has decreased transmission to less than 1%
recommended HIV screening: all females aged 13-64 years, all females who seek STI evaluation and treatment, and all pregnant people at first prenatal appointment and retest during the third trimester if at high risk
HIV infection undergoes three distinct phases: acute seroconversion, chronic HIV without AIDS (without symptoms), AIDS
initial infection → 2-6 weeks after exposure, an acute primary infection occurs for about 3 weeks (fever, pharyngitis, rash, and myalgia) → HIV viral load drops quickly as the immune system controls infection
seroconversion occurs 3–12 months after initial exposure
pt is considered infectious during this time
After acute phase:
asymptomatic, but the virus begins to replicate
CD4 T-cell count <200 = AIDS
immune system continues to battle but falls behind over time
T cells have a viral reservoir that can store various stages of the virus
more present HIV virus = worse the person feels
opportunistic infections occur, qualifying the person for the diagnosis of AIDS
infants born to HIV positive moms will receive HIV medications for 2-6 weeks after birth to decrease the risk of transmission
