Rabies

What is it?

Rabies is a fatal viral disease that attacks the central nervous system of mammals, including humans. It is present in many countries and constitutes a serious public health problem in Tunisia. Once symptoms appear, the disease is almost always fatal, making prevention essential.

Commonly observed signs

These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.

Causes and risk factors

Rabies is caused by a virus belonging to the genus Lyssavirus, mainly transmitted through the saliva of infected animals. This virus travels along the nerves to the brain, causing severe inflammation. Stray dogs and wild animals are the main reservoirs of the virus in Tunisia.

Contact with stray dogs or unvaccinated wild animals greatly increases the risk. The lack of vaccination of domestic animals and rural areas where health surveillance is limited are also contributing factors. Children are particularly exposed due to their frequent proximity to animals.

Transmission

The virus is transmitted mainly by the bite of an infected animal, with saliva contaminating the wound. It can also be transmitted by scratching or contact of infected saliva with mucous membranes or damaged skin. Transmission between animals and humans is possible, making Rabies a major zoonosis.

Diagnosis and care

Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.

Treatment

There is no treatment for Rabies in animals. Once the signs are present, the outcome is always fatal. No antibiotic, no anti-inflammatory, no supportive care modifies the evolution; attempting to treat a suspicious animal only exposes the breeder for additional days. A suspect animal must be isolated without contact with people or other animals, with as little handling as possible, while awaiting the arrival of the veterinarian and instructions from the veterinary services. Never try to open the mouth of a drooling animal, remove a suspected foreign body, give it a drink in its mouth or probe it: these actions are the main cause of human contamination on farms. Do not cut it down on your own initiative, do not cut it, do not consume it or sell it. Any euthanasia decision and any handling of the carcass is the responsibility of the veterinarian and official services. In exposed humans, however, there is effective medical treatment if it is initiated immediately: this is why a doctor must be consulted without any delay.

Prevention

Vaccination

Effective vaccines exist against Rabies. Vaccination of dogs and cats is the pillar of the fight: a protected herd is first and foremost a herd surrounded by vaccinated dogs. In many countries, including Tunisia, anti-rabies vaccination of dogs is the subject of organized campaigns; ask your veterinarian or local veterinary services about dates and conditions. Vaccination of ruminants is possible and may be recommended in areas where the disease is circulating, or for valuable animals. The protocol, the rhythm of recalls and the regulatory framework are the decision of the veterinarian. In humans, preventive vaccination exists for those most exposed, and treatment after exposure is possible and effective if started immediately. These questions are up to the doctor.

Possible complications

Systematic death of the affected animal, within a few days after the appearance of the signs.

Contamination of other animals in the herd bitten during the same dog visit, with cases appearing serially over several weeks.

Human contamination, potentially fatal, through saliva during treatment.

Economic losses and restrictive measures on exploitation.

Injuries caused by an animal that has become aggressive.

When to see a veterinarian

Transmission to humans

Rabies is a fatal zoonosis: once the first signs appear in humans, no treatment can save the patient. This is what makes prevention and speed absolutely decisive. In Tunisia and the Maghreb, stray dog ​​bites are the main cause of human cases. But a rabid sheep is also dangerous, through its saliva, and breeders typically contaminate themselves by putting their hand in the mouth of a drooling animal that they believe is suffocated. The following are considered risky exposures: any bite, any scratch soiled with saliva, any contact of saliva with even a minor wound, an abrasion, the eyes, mouth or nose, as well as handling the head or brain of a suspicious animal. What to do immediately in case of exposure: wash the wound with plenty of soap and water for several minutes, rinse, apply an antiseptic if you have one, then consult a doctor or an anti-rabies center the same day. This prolonged and immediate washing really reduces the risk and should never be neglected. Never wait for the results of animal analyzes to consult: human medical treatment is decided urgently and then continues or stops depending on the results. Always report to the doctor that this involves contact with a potentially rabid animal, including one of your own sheep. Do not consume the meat or milk of a suspect animal, and do not slaughter such an animal yourself. Protect farm children: they are the first victims of stray dog ​​bites and often hide the incident for fear of being scolded.

Prognosis

The prognosis is zero in animals as in humans once the signs are declared: death is constant.

Everything happens beforehand: vaccination of dogs, management of stray dogs, and for exposed people, immediate medical care after a bite. At this point, the disease is completely preventable.
