Rabies, it kills 30-70 thousand people each year around the world (CDC).
40, 000 people are treated for it each year in the United States alone (CDC).
Carried by rabid animals, this viral infection poses a threat to animal lovers alike. The primary problem of rabies is prevention, the effects are severe, and the causes are many. The virus is spread by animals. Warm blooded animals are required to transmit the virus and the disease is almost always fatal (CDC).
It is passed through saliva from the host to the victim also through mucous membranes like the eyes or nose. Yet the most common ways of transition is through a bite with the virus containing saliva. The main animals that hold the virus are: skunk, fox, bat, raccoon, and the coyote (CDC).
These wild animals account for 93% of the cases in the United States. The raccoon still leads as the major carrier and the animal is domestic in the Eastern United States. The skunk is native to the inland states, parts of Texas to Montana and all the way to Wyoming.
The fox and the coyote are both native to the Mid Southern US, and the fox is also spotted in Alaska along the coast. Although not heard of lately, bats are a big carrier of the virus. They are common in most of the states except Hawaii (WebMD. com).
The bats have also spread though out the world, and most recently in Australia. Australia was once free of rabies until rabid bats were found there recently (Mayo Clinic Proceedings).
The Term Paper on Should Animals Be Used For Research Purposes
Should animals be used for scientific research and experimentation? From ancient times, humans have relied on animals for their survival either as food (sheep, cow) or for competition (horses) and companionship (dogs). As humans became more familiar to their environment, they then also started utilizing animals for attainment of knowledge dating back to the days of the great physician Galen (129- ...
The virus can also be spread to domesticated animals, and most cases are reported in the summer and fall months. The three major domesticated animals are: cats, dogs, and cattle. The symptoms in humans are flu-like symptoms, anything ranging from fever to headache.
After a few days after exposure, the human will experience the symptoms of clinical rabies: anxiety, confusion, agitation, hallucinations, and also insomnia (CDC).
These symptoms may last two to ten days. Once the clinical symptoms have appeared the fatality rate is very high. To date, there have only been six cases of survival from the clinical stage of rabies (CDC).
Incubation period ranges form ten days to one year, but the average is 20 days. Also bites closer to the brain will progress faster and bites in the lower appendages will take longer to spread (Mayo Clinic Proceedings).
Early action is the only way to treat rabies. After exposure the best thing to do is seek medical help within the first 48 hours of incubation. Once the time has passed and symptoms begin to show the chances fall drastically. There are 40, 000 people treated annually for rabies exposure in the United States and the cost exceeds 1, 000 dollars per patient (Mayo Clinic Proceedings).
One can also get a pre-exposure vaccine which is administered in three doses within 28 days of the first shot. Most people who receive the pre-exposure vaccine work with animals: veterinarians and people who are considered to be likely in contact with rabid animals.
Post-exposure is urgent after being exposed to a rabid animal. It is administered in six doses, one of which is immune globulin and five other doses of the rabies vaccine over a 28 day period (CDC).
The only way to combat this virus is to control the spread of the animals that carry it. There are only a few spots in the world that are rabies free and most of them are islands: the British Isles, New Zealand, Japan, Hawaii, Taiwan, and many Caribbean islands, Sweden, Norway, and Spain (Mayo Clinic Proceedings).
These areas are free from rabies because of strict importation laws of animals. A fatal disease if one is exposed to it and every precaution should be taken to prevent exposure.
The Essay on Rabies Animals Is The Main Source Of Infection For Human
Rabies Rabies is an infectious disease of animals which is a member of a group of viruses constituting the family Rhabdoviridae. The virus particle is covered ina fatty membrane, is bullet-shaped, 70 by 180 and contains a single helical strand of ribonucleic acid (RNA). Although rabies is usually spread among domestic dogs and wild carnivorous animals, all warm-blooded animals are susceptible to ...
Until the medical society finds a treatment every bite by animals should be considered infected and checked out. The problem is not exposure to animals and through the prevention of rabies with the knowledge of the causes and effect lives can be saved. CDC. 1 Dec.
