Preventing diseases passed from animal to human
Zoonoses is the term applied to a grouping of diseases that are
transferable from canine/feline to human. Basically, these fall
into three groupings based on their means of transmission and
ideally,in the means of treatment and control. The three
groupings are as follows -spread through :1) urine or feces, 2)
hair and skin contact, or 3)bites and scratches.
Spread through Urine or Feces
Hookworms
Hookworms enter the body in the area that directly comes in
contact with the feces-contanimated soil. Seen more commonly in
the South, these parasites are unsuited to ideally live in human
beings. Traditionally they die after crawling several inches
underneath the surface layer of the skin. Inflammation usually
occurs as a result of these parasites in humans and causes a
condition called "creeping eruption" which may last several
weeks or months depending on its severity.
Leptospirosis
Pets may come in contact with this through swimming, drinking,
licking their fur, or by eating food contaminated with animal
urine. Many animals may carry this, though rats are most often
the culprit.
Symptoms in humans are flu-like including chills, body aches,
vomiting, fever and headache. Sometimes kidney damage may occur
or the membranes covering the spinal cord or brain may become
inflamed. This disease is not usually fatal though it does make
its host miserable for weeks at a time.
Roundworms
If these parasites are swallowed by humans they migrate into
the body tissues and may cause damage, including symptoms of
fever and liver enlargement which can last up to a year in
length including symptoms of fever and liver enlargement which
can last up to a year in length.
These parasites are most commonly found in small children(2-4
yrs. of age) who mistakenly swallow the eggs and become
infected. Children playing in an area in which an animal has
defecated in the past, who do not wash their hands after coming
in contact with the eggs and inadvertently sticks their hands
into their mouth are the most common receptors of roundworm.
Only rarely fatal, the disease is traditionally mild though it
may be long lasting.
Tapeworms
Tapeworms can easily be ingested by any pet who swallows a flea
carrying the infected form when biting at or chewing their coat.
Children may get it virtually the same way- minus the coat
chewing. Tapeworm infestation in humans this way is actually
quite rare when compared to infestation from eating undercooked
pork or beef.
Toxoplasmosis
Rarely this may cause death in humans since most people develop
a resistance to it during normal exposure. It can cause many
types of birth deformities in children born to mothers who have
been infected for the first time without having developed an
immunity before becoming pregnant. Most commonly this is "picked
up" through contact with infected cat feces or in contact with
contaminated soil.
Prevention of Waste Transmitted Diseases
There are a few basic precautions everyone should take to
prevent transmission of any of the above diseases. First, clean
up all pet droppings and wash your hands each time you any come
in contact with contaminated soil. It is extremely important to
teach children these steps. Also, if your pet has gone wading or
swimming in any water which may have become contaminated with
animal urine, bathe it at once when you return home.
Spread through Skin/Hair Contact
Fleas
Fleas prefer feeding on your pets though they will not turn up
the chance of of making an occasional meal on humans as well.
Ringworm
Most commonly found in children(though anyone may be infected),
this is caused by a skin/hair eating fungus which first appears
on people as a round, red, scaly area. It grows outward in a
circular formation and is the most common fungal disease
currently reported.
Rocky Mountain Spotted Fever
Tick borne, this disease can cause symptoms such as fever,
chills and headache though it is not usually fatal. Symptoms may
last many weeks and it can be treated with antibiotics.
Most commonly it is transmitted through the bite of an infected
tick. Also, you may become infected while pulling a tick off
your pet . It is best to wear gloves when removing ticks.
Scabies
The less commonly found version of mange(as opposed to the
demodetic version), this may still cause intense itching,
irritation and thickening of the skin. Animal mange may live in
human skin though it cannot reproduce there. Humans have their
own version of the scabies mite.
Prevention of Skin/Hair Contact Diseases
Overall, proper nutritional care and health of your pet is the
best defense against the chance of your pet harboring any of
these diseases. Frequent grooming and herbal repellents are good
choices in combating most of these problems before they become
major. Stress, roaming and contact with other pets are the three
most common points of transmission among the previous diseases.
Wash your hands after pet contact and minimize contact with any
infected pet until the problem is cured.
Diseases Caused by Bites and Scratches
Cat Scratch Fever
Some people will develop a fever, enlarged lymph nodes and
malaise near the area of a bite or scratch from a cat a few
weeks after the occurrence. Though not fatal it can be very
uncomfortable and can be followed by complications. Infected cat
bites may become infected with an entirely different bacteria
though the symptoms are similar.
Probably best, is to thoroughly wash an area bitten or
scratched by a cat and to clean it liberally on a frequent basis
to prevent, hopefully, infection.
Rabies
Virtually 100% fatal once the clinical symptoms appear, this
disease is carried by a virus transmitted through the saliva of
an infected biting animal. Symptoms include frothing at the
mouth, extreme behavioral/personality changes and convulsions
which usually ends in the aggressive, staggering and bleary-
eyed condition.
If you happen upon an animal showing any of these symptoms, get
away from it as quickly as possible and call your nearest animal
control unit. If by chance you are bitten, try to follow it to
where it lives(if it is a stray)so that the proper officials may
capture it for testing. If you do kill it, do not injure the
head as this will be needed for verification. Also, if you are
bitten by an animal exhibiting any of the symptoms above,
thoroughly wash out the wound as quickly as possible and contact
your personal physician. Overall, your chances of getting rabies
are rare though you can never be over cautious.
Prevention of Bite and Scratch Transmitted Diseases
Best advice,keep your pet in tip-top physical condition through
exercise and proper nutrition to reduce its chances of picking
up any parasites from less healthy animals. Also, try to
minimize your pets contact with wild animals or sick pets.
