The best way to reduce the chances of infection is to wash hands regularly, avoid contact with camels and not consume products containing raw animal milk. Live Science. See all comments Don't said:. Meh said:. Comment on rabies fatality rate. Although all warm-blooded animals are thought to be susceptible to rabies, there are strains of the rabies virus multiple bat stains strains are maintained in particular reservoir host s , with some cross over especially in the US between raccoons and skunks.
Although a strain can cause rabies in other species, the virus usually dies out during serial passage in species to which it is not adapted, and non-carnivores cows, horses, deer, groundhogs, beavers AND CATS, like small rodents, are dead-end hosts. The CDC estimates in the US, 1 million dollars per potential life saved is spent by post-exposure prophylaxis in cases of exposure to animals other than bats, canines, fox, raccoon, skunks.
Hundreds of unvaccinated cats are infected with, and die or are euthanized of rabies each year -no way every human exposure to "the kitten in the park " is tracked down. Certainly, many farmers and ranchers are unknowingly exposed. Yet almost all of the people diagnosed in the US yearly, knew they were bitten by a dog when outside the US or handled a bat.
And there have been several incidences since , where people got rabies secondary to solid organ transplants. Species vary in susceptibility to various strains, humans are 'most' susceptible to canine rabies and, in the US, the silver-haired bat strain.
This is a solitary bat with infrequent human interaction, whereas we have much more exposure to big and little brown bats and Mexican free-tailed bats. Only a small percentage of any of these have rabies, -it kills them too!
The virus needs to get to a nerve, so if a bite is not deep enough, or a small viral load is deposited, or the 'victim' immune system responds - an infection will never be established. If the virus is able to get to a nerve, it attempts to travel up an axon, to the brain- again, the immune system may eliminate. As rabies is a slow virus, it can self -immunize, explaining the presence of rabies neutralizing antibodies in Amazonian Indians and others who have never been vaccinated?

Studies show that good spirits and a zest for life promote a strong immune system. Laughing and playing don't just provide for a better quality of life, they also boost the body's defenses.
Negative stress activates the release of adrenalin and cortisol. These hormones can paralyze the immune system. Sensible stress and time management allows the body to rest and replenish new energy. Selective relaxation exercises like meditation, autogenic training and yoga can significantly boost the immune system. Taking walks in the fresh air gives you a change of temperature and exercise - both stimulate the body's defense systems. Mucous membranes also benefit from improved circulation and the increased humidity makes it easier to fight off attacks.
Studies have shown that burning up short chain sugars like fructose and glucose uses up many vitamins that are no longer available to the body. Alternating hot and cold showers help regulate body heat and improve blood flow. An invigorating massage with a massage sponge or brush stimulates the immune system even more.
