Слайд 1The most dangerous diseases.
Rabies

medical
institute, group № 71214
Слайд 2Key facts
zoonotic disease caused by RNA viruses
transmitted in the
saliva of rabid mammals via a bite and scratches
entry to
the central nervous system
incubation period usually ranges 1-3 months after exposure
disease after clinical symptoms is almost always fatal
99% of cases of rabies virus transmission, people come from domestic dogs
Слайд 3Epidemiology
Rabies is found on all continents
exception is Antarctic
Victims are
often children aged 5 to 14 years
Every year, more than
29 million people worldwide receive a post-bite vaccinationRabies Free Countries and Territories

Слайд 4types of rabies
natural type
foci of the disease are formed
by wild animals
wolf
fox
raccoon dog
jackal
arctic fox
skunk
mongoose
bats
urban type
Pets become
infected with rabies after contact with sick wild animalsDogs
Cats
farm animals
Слайд 5Transmission
from animal to human
by a bite
by aerosol through mucous
membranes
by scratches
with saliva
with brain/nervous system
tissue between humans
through transplant surgery
through bites
through kisses
through contamination of mucous membranes (eyes, nose mouth)
aerosol transmission
through corneal transplantations
Слайд 8Forms of the disease
Furious rabies
hyperactivity
excitable behaviour
hydrophobia (fear of water)
aerophobia
(fear of drafts or of fresh air)
death occurs after
a few days due to cardio-respiratory arrestParalytic rabies
muscles gradually become paralyzed (starting at the site of the bite or scratch)
a slowly developing coma
death occurred by coma
Слайд 9Diagnosis
Saliva is tested by virus isolation
Saliva is tested by reverse
transcription followed by
polymerase chain reaction
Serum and spinal fluid are
tested for antibodies to rabies virusSkin biopsy specimens are examined for rabies antigen
in the cutaneous nerves at the base of hair follicles
Слайд 10Treatment
Post-exposure prophylaxis:
1. Extensive washing and local treatment
of the bite
wound or scratch for a minimum of 15 minutes
with
soap and water, detergent, povidone iodine or other substances that remove and kill the rabies virus
2. A course of potent and effective rabies vaccine can
effectively prevent the onset of symptoms and death
Слайд 12WHO response
• In 2015, the World Health Organization (WHO), the
Food and Agriculture Organization of the United Nations (FAO), the
World Organization for Animal Health (OIE) and the Global Alliance against Rabies (GABB) adopted a common strategy aimed at eliminating rabies mortality by 2030 transmitted by dogs.• September 28, World Rabies Day, WHO experts draw attention to the importance of dog vaccination programs as the most effective way to reduce the risk of this disease. All over the world, dog bites are the cause of almost all human deaths from rabies
