UNIVERSAL PRECAUTIONS
When dealing with blood or other body fluids, there are typical precautions
against unwanted and unintentional contact that all medical staff follow.
Even if you are not in a medical career yourself, learning these precautions
will be useful for situations when you don't want to run the risk of disease
transmission. These include:
1) Protective barriers - gloves, face masks, gowns, goggles, etc. If you
are allergic to latex, there are alternative materials such as Nitrile,
Polyurethane, Polyisoprene, and others. Cost will vary depending on type
of material.
2) Wash hands, thoroughly, especially after exposure.
3) Needles should not be handled by any body part.
4) Dispose of single-use (disposable) sharps in a sharps container.
5) Sterilize Nondisposable sharps before use - dry heat ovens and autoclaves
(a device simaler to a pressure cooker) are recommended.
6) Clean wounds to prevent septicemia (details below.)
The following list of diseases are examples of why it's absolutely CRITICAL
you get both you and your donor tested, and why you take precautions anytime
you don't want the risk - diseases can be passed back to the donor as well
as being passed from the donor. This is not a complete list - I covered only
the fairly common disease risks, and there are likely other common ones I
missed, besides the unusual ones I haven't covered here.
HEPATITIS A
Information: Fact
Sheet -- FAQ
Transmitted by: Poor hygeine and sanitation.
Vaccine available? Yes
Preventable? Yes
Fatal? Not usually
Symptoms: Usually seen in adults more
than children - jaundice (yellowed skin), fatigue, abdominal pain, loss of
apptetite, nausea, diarrhea and/or fever
Other notes: Hep A typically has no long-term
infection. Once you've had Hep A it runs it's course, you can't get it again.
Typically spread after contact with infected feces, hence the advice to always
wash your hands after using the bathroom.
HEPATITIS B
Information: Fact
Sheet -- FAQ
Transmitted by: Contact with blood or
body fluids from an infected person. While unprotected sex and needle use
often come to mind, other sources should be considered as well such as toothbrushes,
razors and other personal care items, as well as tatoo equipment that has
not been properly sterilized.
Vaccine available? Yes
Preventable? Yes
Fatal? If there's a chronic infection
- 15-25% of the time.
Symptoms: About 30% of infected people
have NO signs or symptoms. Usually seen in adults more than children - jaundice
(yellowed skin), fatigue, abdominal pain, loss of apptetite, nausea, vomiting
and/or joint pain.
Other notes: May become a chronic infection
if not treated; if it becomes chronic, death can occur in 15-25% of cases.
HEPATITIS C
Information: Fact
Sheet -- FAQ
Transmitted by: Contact with blood or
body fluids from an infected person. While unprotected sex and needle use
often come to mind, other sources should be considered as well such as toothbrushes,
razors and other personal care items, as well as tatoo equipment that has
not been properly sterilized.
Vaccine available? No
Preventable? Yes
Fatal? 1-5% fatality rate as well as the
risk of developing Hepatitis B
Symptoms: 80% of infected people have
NO symptoms. When they do show up, symptoms include jaundice, fatigue, dark
urine, abdominal pain, loss of appetite and/or nausea.
Other notes: If you have Hep C, do not
donate blood, organs or tissue - the infection will spread via organ tissues.
HEPATITIS D
Information: Fact
Sheet
Transmitted by: Contact with blood or
body fluids from an infected person. While unprotected sex and needle use
often come to mind, other sources should be considered as well such as toothbrushes,
razors and other personal care items, as well as tatoo equipment that has
not been properly sterilized.
Vaccine available? No
Preventable? Yes
Fatal? Poentially - liver transplant may
be required if disease progress is serious enough.
Symptoms: Jaundice, fatigue, abdominal
pain, loss of appetite, nausea, vomiting, joint pain and/or dark (black or
brown tea colored) urine
Other notes: May be a co-infection (occurs
simultaneously) or superinfection in people with Hep B. Liver disease more
common in this case.
HEPATITS E
Information: Fact
Sheet
Transmitted by: Contaminated food or
water; found in feces of infected people AND animals.
Vaccine available? Not specifically for
Hep-D, however Hep-B vaccine prevents Hep-B/Hep-D co-infections.
Preventable? Yes
Fatal? Unknown
Symptoms: Symptoms appear within 2 to
20 days after contact and typically includes red and sensitive skin followed
by blisters. Flu-like symptoms are common, and urination may be painful.
Other notes: A person may be contagious
without showing visible signs - not everyone gets blisters or or other typical
warning signs. Read the link for details.
HERPES
Information: Fact
Sheet Transmission Info
Transmitted by: Spread by skin to skin
contact from the site of infection. Typically this involves open sores making contact, but there are asymptomatic people who show no signs but are still contagious. This means the virus will spread without visible open sores.
Vaccine available? Not yet, but one is
in development
Preventable? Yes
Fatal? Unknown - check links for details.
Symptoms: Jaundice, fatigue, abdominal
pain, loss of appetite, nausea, vomiting and/or dark (black or brown tea colored)
urine.
Other notes: More commmon in developing
countries, but not impossible to find elsewhere.
HIV / AIDS
Information: FAQ
Transmitted by: Body fluid contact through
broken skin or mucous membranes. In addition, it has been passed from mother
to baby during pregnancy, delivery or breast-feeding.
Vaccine available? No, but one is in
human trials for the slow varient
Preventable? Yes
Fatal? Usually
Symptoms: HIV/AIDS symptoms can mimic
those of other diseases; the only sure way to tell is to get a test. Symptoms
may include rapid weight loss, dry cough, fever/night sweats, uneplained fatigue,
swollen lymph nods, diarrhea, severe lack of appetite, and others.
Other notes: At least two base forms
known - one is the usual slow-acting varient most people are familiar with,
however new in late 2004/early 2005 is a varient that runs it's entire course
(including patient death) in about six (6) months. You cannot rely on symptoms
alone to establish whether or not you or someone else has HIV/AIDS! If you
need a test, call your local doctor, clinic, or other public health center
to see where you can have it done locally.
PRION DISEASES
Bovine Spongiform Encephalopathy (BSE / "Mad Cow Disease")
Creutzfeldt-Jakob Disease (CJD, vCJD, nvCJD)
Kuru (Found mostly in cannibalistic societies - not covered in this article)
Information: Fact
Sheet/BSE -- Fact
Sheet/CJD
Transmitted by: Malformed proteins (prions)
ingested in contaminated blood or meat. Blood transfusion from infection persons.
Also, eating meat that has been contaminated with the virus in infected animals
- the virus has been found in the brain, spinal cord, retina, dorsal root
ganglia (bundle of nerves at the base of the spine), distal ileum (lower small
intestines) and bone marrow, suggesting that these represent the highest risk
of transmission, and if processing facilities are not hygenic enough, contaminated
parts may come in contact with uncontaminated parts.
Vaccine available? No
Preventable? Yes
Fatal? Yes - 100% (No cure or treatment
available)
Symptoms: BSE: Characterised by loss
of motor control, dementia, paralysis wasting and eventually death typically
following pneumonia. CJD/etc.: When symptoms begin, they start with psychiatric
or sensory abnormalities, lack of coordination (early) and progresses to dementia
and muscle spasms late in the disease.
Other notes: Besides cows, BSE and CJD/vCJD/nvCJD
have been found in elk, deer and other cloven-hoofed animals. A simaler disease
called "Scrappie" is found in sheep, and is thought to be the source
of BSE in cows when animal parts are used in cattle feed.
SEPTICEMIA / SEPTIC SHOCK
Information: Info
#1 Info #2
Transmitted by: Any pathogenic organism
(bacteria, fungi, virus) can cause septicemia and septic shock. These organisms
can enter the body through several means - the site of another infection,
surgical procedures, IV lines/needles, catheters, and physical injuries that
break the skin. Septicemia occurs about 66% of the time in hospital patients.
Vaccine available? No
Preventable? Yes
Fatal? Yes, 5-60% fatality rate depending
on complicating factors such as which invading organizm it is, and whether
the immune system is compromised.
Symptoms: Most patients have fever and
chills that appear abruptly. Some may have low body temperature, rapid breathing,
changes in mental state, etc. Loss of interest in food or surroundings may
also develop. If it is being caused by meningitis bacteria, there may be a
hemorrhagic rash - clusters of tiny blood spots that look like pin pricks.
If untreated, these gradually get bigger and start to look like fresh bruises.
Other notes: This is not something to
fool around with - it's so simple to prevent by washing/cleaning any wounds,
there's no excuse for poor hygeine.
SYPHILIS
Information: Fact
Sheet
Transmitted by: Typically by sexual contact;
an open wound will spread the germ througH a mucous membrane or broken skin.
It can be passed from mother to child during pregnancy.
Vaccine available? No
Preventable? Yes
Fatal? Yes, if left untreated
Symptoms: Primary stage is a sore at
the site of infection that disappears within a few weeks. Secondary stage
is a skin rash with penny-sized sores that appears 3-6 weeks after the sores
appear. The rash may heal within several weeks or months. Second stage is
contagious! If the disease is untreated and progresses to tertiary stage,
the bacteria attack the heart, eyes, brain, nervous system, bones, joints
or almost any other part of the body.
If the disease gets into the nervous system it is called neurosyphilis, and
the time from infection to developing signs can take up to 20 years.
Other notes: Syphilis increases the risk
of transmitting or acquiring HIV/AIDS by 300-500%. Symptoms can mimic those
of many other diseases, so syphilis can often get left untreated until it's
too late. Even if the disease is treated and eradicated, damage already done
to organs and body parts cannot be reversed.
