How to test for rabies virus?

Rabies is a dangerous infection, usually spread from animals that carry rabies viruses to humans through bites, scratches with saliva. Rabies virus testing is required as soon as possible to accurately diagnose whether or not the disease is infected, serving early treatment, avoiding endangering the patient's life.

1. Rabies Overview

Rabies is an acute encephalitis, myeloid disease caused by the rabies virus Rhabdovirus of the family Rhabdoviridae, strain of Lyssavirus. Dogs and bats are 2 types of animals that mainly cause rabies in humans through licking, bites,… Rabies can also be transmitted from person to person when exposed to saliva, wounds of rabies patients. According to World Health Organization statistics, every year more than 55,000 people die from rabies.

The incubation period of rabies usually lasts 1-3 months. However, the disease can also incubate for a short time (less than 1 week) or a long period (more than 1 year). The initial symptoms of rabies are similar to influenza with manifestations including dizziness, fever, headache,… Patients may also have symptoms such as unpleasant itching at the site of a bite. After that, the person is prone to brain dysfunction, confusion, anxiety, agitation, severe progress that leads to coma, insomnia, hallucinations,… The urgent stage of the disease usually lasts 2-10 days. When the disease has shown clinical symptoms, the patient will almost die.

For the prevention of rabies, immediately after a dog bite, the patient should treat the wound on the spot and go to a medical facility to be vaccinated. Rabies vaccination can cause a number of side effects such as swelling, redness, pain and itching at the injection site; rare nausea, dizziness.

2. Rabies virus testing

In humans, the rabies virus cannot be detected at an early stage when symptoms of the disease have not yet appeared. In general, rabies viral testing in humans is less applicable and is mainly performed in patients who have shown clinical manifestations. Rabies viral testing includes tests on humans and animals. Specifically:

2.1 Rabies testing in humans

Commonly applied testing methods are:

  • Blood tests: Leukocycycy are often high, the rate of polycythemia increases;
  • Urine tests: Increased proteinuria and leukocycysis;
  • Encephainal fluid test: Results such as encephalitis, meningitis with mild increased pressure, mainly monocytitis;
  • Imaging: CT or MRI scan results in nons specific changes.

In addition, some diagnostic tests of the disease are less applicable but give the correct result: Perform a rabies virus test in the product (saliva, serum, cerebral fluid and nape skin biopsy,…) with a direct immunofluorescent antibody test (IFA) or isolating the rabies virus-finding product by cell culture (or culture on mice). Blood and cerebral fluid tests are aimed at checking if the body already has anti-rabies antibodies. Nape of the nape of the nape of the neck is aimed at finding the antigen of the rabies virus. Today, new techniques can detect the RNA of the rabies virus by PCR reaction or Real Time – PCR reaction.

2.2 Rabies testing in animals

Mainly carried out in dogs. There is currently no accurate rabies test in living animals. Rabies viral testing is carried out only when the animal has died. To perform the test, it is necessary to take the brain of the animal and send it to the test site to determine if a person is at risk of exposure to rabies pathogens after being bitten by a dog or cat. Patients should go to reputable medical facilities for an accurate diagnosis of rabies.

Once the disease has arisen, rabies cannot be treated, the person will definitely die. Therefore, rabies viral testing plays an important role for people who have just been bitten by an animal, have a high risk of infection, help with effective preventive treatment, avoiding the disease from developing i.m.
