Transcript Chapter 29: Additional Health Conditions

Infectious Disease in Athletics
Role of the Immune System
• Collection of disease fighting cells that
neutralizes foreign substances
– Illness results when immune system does not
neutralize foreign substances (antigens)
– Cell-mediated response, humoral immune
response (B-cells that produce antibodies), or
nonspecific immune response (inflammation)
• Auto-immune response against the body
leads to damage of body’s own tissues
Viral Infections
• Rhinovirus (Common Cold)
– Etiology
• Over 100 different rhinoviruses
• Transmitted by either direct or indirect contact
(cough, sneeze, speaking, touching contaminated
article)
– Sign and Symptoms
• Begins w/ scratchy, sore throat, stopped-up nose,
watery discharge and sneezing
• Second batch may produce thick yellow nasal
discharge, watering eyes, mild fever, sore throat,
headache, malaise, myalgia, dry cough
– Secondary - laryngitis, tracheitis, acute bronchitis,
sinusitis, and otis media
– Management
•
•
•
•
Symptomatic treatment (may last 5-10 days)
Non-prescription cold medications
Eat a balanced diet, consume 64 oz. of water
Avoid emotional stress and extreme fatigue
• Influenza (Flu)
– Etiology
• Caused by myoviruses (A, B, C)
– Type A is most common
– Virus enters through cell genetic material

inflamed respiratory mucous membrane w/ coryza
• General aches and pains, headache becomes worse
• Weakness, sweating, fatigue may persist for many days
– Management
• Bed rest and supportive care
• Symptomatic care should be avoided by those under age 18 (
Reye’s syndrome)
• Steam inhalation, cough medicines, and gargles

will experience enlarged spleen)
• Possible jaundice, skin rash, puffy eyelids
– Management
• Supportive symptomatic treatment
• Acetaminophen for headache, fever and malaise
• Resume training after 3 weeks after onset if spleen not markedly
enlarged/painful, athlete is afebrile, liver function is normal, and
pharyngitis is resolved
• Rubella (German Measles)

– Etiology
• Childhood disease
• Incubation time of 10 days following exposure
– Sign and Symptoms
• Sneezing, nasal congestion, coughing, malaise,
photophobia, spots in mouth, conjunctivitis, and
elevated fever (rash appears - causes itching)

• Pain w/ jaw motion and swallowing; increased or
decreased saliva production
– Management
• Varicella-zoster immune globulin w/in 96 hours of
exposure will prevent clinical symptoms in normal
healthy children
• Acyclovir meds should be administered to adolescents
and adults w/ in 24 hours of exposure
• Anti-itching medications to prevent scratching
Respiratory Conditions
• Sinusitis
– Etiology
• Stems from upper respiratory infection caused by a
variety of bacteria
– Sign and Symptoms
•
•
•
•
Nasal mucous swell and block ostium of paranasal sinus
Painful pressure occurring from accumulation of mucus
Skin over sinus may be swollen and painful to the touch

Syphilis
Gonorrhea
• Transmittedvaginal/oral/rectal sex
• Symptoms- 3-10 days
following exposure
• Milky discharge from
penis/vagina/rectum
• Burning/itching on
urination
• If untreated can cause
PID/ectopic pregancy in
women
• Sterility in both sexes
• Joints, heart valves, brain
• Gonorrhea (clap)
– Etiology
• Caused by organism infection - gonococcal bacteria
which is spread through intercourse
– Sign and Symptoms
• In men - experience tingling of urethra followed by
2-3 hours of greenish yellow discharge and painful
urination
• 60% of women are asymptomatic
• Females will experience vaginal discharge
• May result in sterility if not treated or arthritis
– Management
• Penicillin
• Avoid sexual contact until it is known that the
disease is no longer active
Chlamydia
• Most prevelant STD
worldwide
• Transmitted thru vaginal/anal
sex
• Symptoms- up to 75% of
women and 15% of men are
asymptomatic
• In men & women abnormal
discharge and burning on
urination.
• Swelling of the testicles in
men and abdominal pain and
painful intercourse in women
Chlamydia cont….
• Possible consequences
for infected persons:
• If untreated in women
30% will experience
PID, infertility and
chronic pelvic pain
• In men epididymitis,
inflammation of the
testicle and sterility
• Chlamydia
– Etiology
• Caused by bacterial organism
– Sign and Symptoms
• May result in pelvic inflammation and is important
cause of infertility and ectopic pregnancy in females
• In males, inflammation occurs along with purulent
discharge 7-28 days after intercourse
• Painful urination and traces of blood in urine,
vaginal discharge
• Can cause conjunctivitis and pneumonia in
newborns
– Management
• Identify infection and exact organism present
• Treat with antibiotics
Syphilis
• Transmitted through
vaginal/anal/oral sex
• Infection can occur by nonsexual contact if sores, rashes
or mucous patches come in
contact with broken skin
• SymptomsStage 1- painless sores
(chancres) appear on genitals
or any other part of the body
Primary Lesion in Female
Syphilis cont….
• Chancre heals with
several weeks
• Secondary syphilis-if
chancre is not treated,
organism enters the
bloodstream causing
rash, sore throat, fever,
swollen glands and
mucous patches
Syphilis cont….
• Symptoms from secondary syphilis disappear after
several weeks
• Tertiary syphilis occurs years later after spirochete has
damaged major organs
– Damage to heart and vessels
– Brain damage resulting in mental illness
– Damage to spinal cord causing paralysis
– Deafness/blindess
• Syphilis
– Etiology
• A spirochete bacteria is the organism related to syphilis
and enters body through mucous membranes or skin
lesions
– Sign and Symptoms
• 4 stages
– Incubation is usually 3-4 weeks but could be anywhere from
1-13 weeks; painless chancre or ulcer forms that heal w/in 4-8
weeks (can occur on penis, urethra, vagina, cervix, mouth,
hand, foot or around eye)
– Secondary stage occurs 6-12 weeks after initial infection and
is characterized by a rash, lymph swelling, body aches, mild
flu-like symptoms and possible hair loss
– Latent syphilis is characterized by no or few symptoms - but if
untreated it may result in tertiary syphilis
– Sign and Symptoms
– Late stage is characterized by deep penetration of
spirochetes that damage skin, bone, cardiovascular system
and nervous system
– Late stage may develop w/in 3-10 years of infection and
cause neurosyphilis - muscle weakness, paralysis and
various types of psychoses
– Management
• Penicillin is used for all stages
• Other drugs may be required due to increased
resistance
Treatments for Bacterial STDs
• Gonorrhea and chlamydia can be cured with
antibiotic medication however, it cannot undo the
damage done prior to treatment
• Syphilis is treated with penicillin and other 3rd
generation antibiotics but these medications are
only effective in primary and secondary syphilis.
There is no cure for tertiary syphilis.
Viral STDs
Genital Herpes
Human Papillomavirus (genital warts)
HIV
Hepatitis B
Genital Herpes
• Spread by direct sexual skin
to skin contact with infected
site during vaginal/anal/oral
sex

in the genital area, anus,
buttocks and thighs
• Sores heal after several weeks
but often recur
• No cure-
• Genital Herpes

• Develops 4-7 days following sexual contact
• Begins to crust 14-17 days in primary genital herpes
and 10 days in secondary
• Females may be asymptomatic while males will
experience itching and soreness
• Development of lesions
– Management
• Herpes and pregnancy
• No cure just systemic medication (antiviral
medications) to lessen early symptoms or the disease
Genital Warts
• Cause by HPV
• Occur 1-3 months after
exposure
• Emerging as a common
STD
• No Cure- treatment is
aimed at surgical
removal
• Associated with
increased risk of anal
cancer
• Genital Candidiasis
– Etiology
• Transmitted through sexual activity and appear as
warts on the glans penis, vulva or anus
– Sign and Symptoms
• Cauliflower-like wart or can be singular
• Soft, moist pink or red swellings that develop
cauliflower-like head

existing STD
• Called NGU
(nongonoccocal urethritis)
in men
• Causitive agent is
protazoa
• Symtoms are foul, whitish
discharge, itching,
vulvular irritation
• Trichomoniasis
– Etiology
• Caused by the flagellate protozoan trichomonas
vaginalis

•
•
•
•
Vaginal discharge that is greenish yellow and frothy
Causes irritation of the vulva, perineum and thighs

Males tend to by asymptomatic but may experience
purulent urethral discharge
– Management
• 2 grams of metronidazole cures up to 95% of cases
in women
• Males require 500mg twice daily for 7 days

intercourse
Pubic Lice
• Sexually transmitted
• Also by contaminated
linens, clothing or
other articles
• Parasite is the
causative agent
• Symptoms include:
intense itching of
perineal area
Play safe- protect
yourself
•
•
•
•
•
Abstinence is 100% effective
Have sex with only one uninfected partner
Talk to your partner
Consider all potential sex partners as infected
Use condoms, birth control foams, creams or jelly.
These kill many STD germs
• Get checked for STDs
• Know the signs and symptoms of STD
• If you have an STD, your partner must get
treated as well
