2. • Rabies is one of the most well-known and
deadly virus that attacks the nervous system
which is commonly called hydrophobia.
• Rabies is a viral zoonotic neuroinvasive
disease that cause brain inflammation (acute
encephalitis) in mammals and dog is
significant source that carried rabies disease in
many other countries.

3. • Dogs that infected with rabies will show signs and
symptoms such as foaming at the mouth and
extremely aggressive.
• However in some case infected animals can be
very calm and tame so you must be really careful
not to stay near or get bitten by strange animals.
• Death is always certain once a dog is infected
with rabies virus. This deadly disease can be
prevented with a proper vaccination from
veterinarian.

4. Spread and Transmission of the Disease
• Rabies are transmitted by infected animal biting a
non-infected animal.
• Travelers, veterinarians or peoples who work
closely with wildlife animals have highest risk of
exposure with rabies disease because animals in
wildlife nature are not vaccinated but luckily
there are prevention vaccine available.
• Rabies remain viable for less than one day and
cannot live long outside the host.

5. The rabies virus can be carried by
warm-blooded mammals such as
• Human
• Dog
• Cat
• Monkey
• Cow and cattle
• Wolf and fox
• Bat
• Squirrel
• Rabbit
Other non-mammals such as fish, bird, reptiles and
amphibians do not carry rabies disease.

6. Dog rabies symptoms
• The infection of virus are divided into 3 stage:
prodromal, furious (or excitative) and
paralytic.
Prodromal stage can last up to 6 months long
as the virus slowly spreads over the nervous
system and travel to the brain. During this
period infected dog sometime may not show
any signs or symptoms at all.
By: Gabriel H. dos Santos United Safety International Ltd.
7. Furious or excitative stage may last for
several days (usually 2-4 days) after the
prodromal stage however not all dogs
experience this stage.
This is the most dangerous period because
infected dog can spread rabies disease and
the symptoms are as follow.

8. • Extremely mean and aggressive
• Totally uncontrollable
• Break it own teeth by biting objects
• Constant growling
• Biting
• Dilated pupils
• Restless
• Disorientation
• Seizures
By: Gabriel H. dos Santos United Safety International Ltd.
9. Paralytic stage last for 2-4 days and the symptoms
are as follow.
• choking
• dropping of the lower jaw
• unable to swallow any food
• foaming at the mouth
• paralysis of jaw, throat and chewing muscles
After the paralytic stage infected dogs will usually
be in coma. It may also experience respiratory
problems and failure then pass away.

11. • The incubation period of rabies in people is
also variable (depending upon factors such as
the site and severity of the bite), but averages
three to eight weeks.
• Following an exposure to rabies, there is
normally a window of opportunity (usually
measured in days) in which the patient can
receive a series of shots to keep him/her from
developing disease.
• Once symptoms begin, the outcome is almost
always death.

12. Symptoms in Human being
Early symptoms of rabies often include:
• Sensory changes at the site of the bite
(numbness or tingling).
• Fever
• Headache
• and a general feeling of discomfort.
By: Gabriel H. dos Santos United Safety International Ltd.
13. • As the infection progresses, the patient may
exhibit:
• excitability,
• anxiety,
• aerophobia (abnormal aversion to air in
motion)
• and hydrophobia (abnormal fear of water).
By: Gabriel H. dos Santos United Safety International Ltd.
14. Other neurological symptoms may include:
• Mental confusion
• Paralysis
• Delirium,
• and convulsions.
Without medical intervention, DEATH usually
occurs within two to six days.

Be careful, not all the time you animal you see so calm and tame will necessarily mean that it it may not transmit the virus
Dogs must be vaccinated early before they get infected with the virus.
Rabies can also be transmitted sexually from infected to a no-infected animal
Don’t just your dog be wandering the streets because it may get infected by fighting with other dogs or by sexual mean
Whenever one of these animals bytes you, wash the injury immediately with enough water and enough soap and look for the Doctor in order to be vaccinated.
In this stage infected dogs may not show any signs or symptoms at all.
Due to the brain inflammation, the dog will start confusing things and people and become extremely aggressive
Doctor in Cabinda central hospital say that in just one day they can receive from 5 to 10 people bitten by dogs and most of them were bitten by their own dogs and some died couple of weeks later.
At this stage, these are the symptoms
Mental confusion, the fact of not eating due to the paralysis and respiratory disturbances will cause the dog to fall in coma.
What to do if your dog gets infected by the rabies virus?
A 1: Isolate it and keep it away from reach of children
A 2: Do not trust on your dog, it is confused and with its nervous system altered it may byte you brutally (wildly)
A 3: Do not allow it to escape from the chain or captivity
A 4: Do not tie it with conventional rope because it may cut it with its teeth.
Whenever one of these animals bytes you, wash the injury immediately with enough water and enough soap and look for the Doctor in order to be vaccinated.
With medical intervention, the course of disease may be prolonged to several weeks before death ensues. The diagnosis of rabies in humans may be complicated since other diseases that affect the brain produce similar symptoms.
