Rabies - a virus that can be transmitted to humans through the bite of an infected animal.Unfortunately, rabies is not treated, when they begin to show symptoms of rabies in humans, and a few days after the onset of symptoms usually occurs death.Fortunately, rabies can be prevented, and the disease can be cured if, immediately after the bite a person was vaccinated against rabies Vaccination against rabies - the only escape from a deadly infection .
If you are bitten by a wild animal, you should be tested for rabies.
symptoms of rabies in humans
Any animal bites are a potential risk for rabies, so you should seek immediate medical attention.Once ingested, the rabies virus multiplies, moving on the central nervous system, and finally a fatal brain inflammation.The first symptoms of
The first symptoms of rabies - moderate, but they quickly turn into serious symptoms.
The incubation period - the time that elapses before the symptoms to develop after a person becomes infected with a virus.The incubation period for rabies usually takes from two to twelve weeks, although it may be as short as four days.In very rare cases, the incubation period is more than a year.
infection is closer to the brain, the shorter the incubation period.For example, a bite to the face, head or neck will result in a shorter incubation period than bite in the arm or leg.
The incubation period is important because it is the only time when treatment can be successful.
The first symptoms of rabies are often vague and can be easily confused with other, less serious infections.These include:
- high temperature: 38ºC or higher
- extreme fatigue
- sleep problems
- sore throat
About half of people also experience pain and a tingling sensation at the site of infection.
The first symptoms of rabies last from two to ten days, and then develop more severe symptoms.
There are two types of progressive rabies:
- furious rabies, which has four cases out of five, or 80%
- quiet, or paralytic rabies, which includes the remaining 20% of cases.
last stage of rabies is called acute neurological period.
furious rabies is characterized by episodes of very strange and hyperactive behavior, interspersed with periods of relative calm.During these episodes, a person may exhibit some or all of the following symptoms:
- aggressive behavior such as biting or attempting pugnacity
- hallucinations (the person sees or hears something that in reality is not)
- delusion - the beliefin what is obviously not true
- excessive salivation
- high temperature (fever)
- excessive sweating
- hair on your skin standing on end
- men - sustained erections
People with furious rabies, hydrophobia is also developing(fear of water).When it first appears sore throat or difficulty swallowing.When trying to take a sip of experiencing muscle spasms in the throat that lasts a few seconds.Then, look, sound, or even the mention of water or any other liquid may provoke further spasms.Also, there will be fear of bright light (photophobia), and fear of air (aerophobia).
A few days after the onset of symptoms the patient goes into a coma and dies, usually as a result of cardiac or pulmonary disease.
Quiet or paralytic rabies
quiet fury, sometimes called paralytic rabies Rabies - forecast unfavorable , characterized by muscle weakness, loss of sensation and paralysis (inability to move one or more muscles).It usually begins in the hands and feet, then spreads throughout the body.
hydrophobic at a quiet fury usually does not happen, although the muscles may have spasms.As with furious rabies, rabies patient quiet falls into a coma and later died of cardiac or pulmonary disease.
Rabies can not be diagnosed until the onset of symptoms.If you are bitten by an animal, and you are experiencing symptoms, your body produces antibodies Antibodies - "soldiers" immunity to rabies.Doctor will prescribe a blood test to detect these antibodies to confirm the diagnosis.
