Rabies

Overview of Rabies

• Humans are most frequently infected from dogs and bats.
• In Europe, the maintenance host is the fox. The incubation period varies in humans from a minimum of 9 days to many months but is usually between 4 and 8 weeks
• Severe bites, especially if on the head or neck, are associated with shorter incubation periods. Human rabies is a rare disease, even in endemic areas.
• However, because it is usually fatal, major efforts are directed at limiting its spread and preventing its importation into uninfected countries, such as the UK. [1][2]

Causes of Rabies

• The etiological agent is an RNA virus belonging to the group of rhabdo viruses
• It is a rod-shaped virus approximately 180 by 75 nm. When isolated first from animals, it was called “street virus”.
• Saliva of infected animals. [1][2]

AAA

Risk factor of Rabies

• The bite takes place in a geographic area where rabies is still present
• The animal looks ill or displays abnormal behaviour
• The animal’s saliva comes in contact with a wound or mucous membrane. [3]

Pathogenesis refers to the development of a disease. It’s the story of how a disease gets started and progresses.

This is the entire journey of a disease, encompassing the cause but going beyond it.

Pathophysiology of Rabies

• Disease is caused by one of three polioviruses, which constitutes a subgroup of the enteroviruses.
• Infection usually occurs through the nasopharynx
• The virus causes a lymphocytic meningitis and infects the grey matter of the spinal cord, brainstem and cortex
• There is a particular propensity to damage anterior horn cells, especially in the lumbar segments.[1]

Sign & Symptoms of Rabies

• Fever
• Paraesthesia at the site of the bite
• Nausea and headache and nonspecific upper respiratory tract symptoms.
• A prodromal period of 1–10 days, during which the patient becomes increasingly anxious, leads to the characteristic ‘hydrophobia’.
• Although the patient is thirsty, attempts at drinking provoke violent contractions of the diaphragm and other inspiratory muscles.
• Delusions and hallucinations may develop, accompanied by spitting, biting and mania, with lucid intervals in which the patient is markedly anxious.[1][2]
• Cranial nerve lesions develop and terminal hyperpyrexia is common.
• Death ensues, usually within a week of the onset of symptoms.

Neurological involvement may present as i.e.:

1. The spastic (furious) form i.e.:

• The lesions are more marked in the brain stem, cranial nerves, limbic system and higher centres. painful spasms. These are most marked and characteristic in the oropharynx.
• Swallowing liquid and later on a spray of water, its sight or even thought of it produces painful oropharyngeal spasms with respiratory distress. Hydrophobia.
• Though not pathognomonic, this is almost confirmatory of the diagnosis.[2]

2) The paralytic form i.e.:

• This is characterized by ascending paralysis.
• It may start as monoplegia or paraplegia.
• Paralytic form is known to occur more often after vampire bat bites.
• Hydrophobia is rare.
• Patients may survive for a month even without intensive care [2]
•  

Clinical / Physical Examination For Rabies

• Hyperpyrexia alternating with hypothermia
• Tachycardia
• Respiratory and vascular collapse
• Bradycardia
• Percussion myoedema (mounding of the muscle at the percussion site)
• Bite marks
• Bruises
• Hypersalivation
• Lacrimation
• Sweating
• Dilatation of the pupils. [4]

Diagnosis of Rabies

• Immunofluorescent testing: of skin biopsies or corneal impressions can establish diagnosis ante-mortem
• Viral detection: in saliva, throat swabs also tracheal aspirates is possible in 100% on days 0-4, 50% on days 5-8 and 9-12, and 14% on days 13-16. Virus isolation may take several weeks
• Antibody detection: is the most successful method for confirming diagnosis; however, its success depends on maintaining life until antibody can be detected.
• Post-mortem diagnosis: can be achieved by observation of Negri bodies in the brain, virus isolation, immunofluorescence of viral antigen in the brain, PCR and electron microscopy of brain.[2]

Differential Diagnosis of Rabies

• Encephalitis and other neurological disorders leading to paralysis.
• The spasms of tetanus may resemble hydrophobia especially if they involve the pharyngeal muscles
• Psychiatric conditions, such as maniac excitement and hysteria and drug reactions such as akathisia have to be differentiated at times.
• chaotic subjects adopt hydrophobic manifestations, but absence of aerophobia excludes this condition. [2]

Complications are what happen after you have a disease. They are the negative consequences of the disease process.

Investigation of Rabies

• The CSF shows a lymphocytic pleocytosis
• Rise in protein also a normal sugar content.
• Poliomyelitis virus may be cultured from CSF and stool [1]

Treatment of Rabies

• Once the disease is manifested treatment is only symptomatic
• There is no specific treatment. Treatment aims at controlling spasms with muscle relaxants, maintenance of hydration by intravenous fluids, and assistance to ventilation
• Those who attend on the patients should use gloves, masks, and protective goggles.
• Though the virus eliminated in human saliva is not very virulent, as a matter of abundant caution, attendants who have been inadvertently exposed to very close contact with rabies may be advised to take a course of prophylactic inoculation.[2]

Prevention of Rabies

• Vaccinate dogs and cats against rabies as required by law.  All dogs and cats more than four months of age must be vaccinated against rabies.  Keep vaccinations current at all times.
• Keep dogs and cats under control.  Animal control laws prohibit allowing animals to roam unsupervised.  Roaming pets are more likely to have been exposed to rabies than those supervised by their owners.
• Leave stray or unknown dogs and cats alone.  Loose animals are more likely to have been exposed to rabies and to attack others.  Keep pets away from strays, too.
• Do not keep wild animals as pets.  Even a raccoon or skunk born in captivity may be a rabies carrier. Local laws prohibit acquiring of keeping such animals as pets. There are no approved vaccines or known quarantine for wild animals.[6]

Homeopathic Treatment of Rabies

Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines selected after a full individualizing examination and case-analysis.

which includes

• The medical history of the patient,
• Physical and mental constitution,
• Family history,
• Presenting symptoms,
• Underlying pathology,
• Possible causative factors etc.

A miasmatic tendency (predisposition/susceptibility) also often taken into account for the treatment of chronic conditions.

What Homoeopathic doctors do?

A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’?.

The disease diagnosis is important but in homeopathy, the cause of disease not just probed to the level of bacteria and viruses. Other factors like mental, emotional and physical stress that could predispose a person to illness also looked for. No a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition.

The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can greatly improved with homeopathic medicines.

Homeopathic Medicines for Rabies:

The homeopathic remedies (medicines) given below indicate the therapeutic affinity but this is not a complete and definite guide to the homeopathy treatment of this condition.
