As Dr. Such a behavior can be seen in rabies-infected animals as well. According to Dr. Hueffer and his team, this is the first time that experimental evidence has been presented to show how rabies interacts with other cells in the nervous system to induce an altered behavior that determines infected hosts to help spread the virus.

In this op-ed, Dr. Maria L. Hueffer said that although vaccinations for rabies were first developed in the midth century, scientists have struggled to explain how the virus can induce aggressive behavior in animals like dogs, which contribute up to 99 percent of all rabies transmissions to humans, according to World Health Organization estimates.
Yet this virus can reprogram a dog's behavior so it loses fear, becomes aggressive and bites, which allows the virus to spread through the dog's saliva. Hueffer said these behavioral changes are well known and cemented into the American narrative. In the novel "Old Yeller," Travis must put down his beloved dog after it is bitten and infected by a rabid wolf. He said studying rabies in the brain is difficult because the rabies virus doesn't physically alter the brain in very telling ways.
Usually, there is brain inflammation, but scientists must sample the brain and specifically test for rabies virus to confirm infection. Prior research in the s and s focused on how the rabies virus binds to and interacts with specific muscle receptors that receive signals from nerves to control muscle contraction.
The research revealed that a molecule called a glycoprotein on the surface of the rabies virus can bind to nicotinic acetylcholine receptors in the muscles. The virus then enters and hijacks muscle and nerve cells where it replicates and travels up the nerves to infect the brain and other tissues.
Other research found a string of amino acids within the rabies glycoprotein that is almost identical to an amino acid sequence found in snake venom that inhibits nicotinic acetylcholine receptors. Hueffer said he and co-author Marvin Schulte realized a connection. Rabies is a serious virus that affects animals, and one of the symptoms they may show is aggression. Why do rabies-infected animals behave like this?
Rabies causes these types of symptoms in infected individuals because its effects on their neurological wiring can change how aggressive or passive an animal behaves. Animals with rabies have generally unusual behavior like fear of water or anxiety. Due to this, animals become more aggressive and often attack.
The World Health Organization WHO has also found that children under 15 are more likely to develop rabies after being bitten by an infected dog or cat because they have a greater risk of coming into contact with these potentially rabid creatures—not only dogs but cats can transmit this deadly virus too! They may even exhibit signs such as scratching themselves frequently and experiencing paralysis. He primarily writes amazing stories about cultures and shares different ideals with our readers through his stories.
He believes that people empowerment is important especially during these trying times. Diagnosis is done after death, by testing the brain. Rabies post-exposure prophylaxis is generally recommended for individuals who have a possible exposure to the virus.
This regimen involves a dose of rabies immune globulin , which gives some immediate protection, followed by a series of four rabies vaccines administered in the arm, just like other vaccines to allow the body to mount its own immune response. The combination of immune globulin and the vaccines will stop the growth of the virus in the body, preventing further disease development. People who are at a high risk of rabies exposure think: veterinarians, animal lab workers or handlers, or people traveling to parts of the world where rabies is more prevalent, who may be around animals may be offered rabies vaccines as a preventive measure.
If they work with animals regularly, they will have to stay up to date on their vaccinations with guidance from a doctor. This includes avoiding bats or other wildlife that appear to be acting strangely, as well as keeping your pets up to date on their rabies vaccines. You can ask your veterinarian about how often your cat or dog needs to be vaccinated. Luckily, rabies in domestic cats and dogs in the U. Also, keep an eye on your pets if they go outdoors. You also have to be on alert while traveling abroad: Tourists visiting areas where rabies is common are also susceptible; a Virginia woman died in after reportedly being bitten on the hand by a puppy that was thought to have rabies at a yoga retreat in India.
