In people who have been exposed to rabies, the [[rabies vaccine]] and sometimes [[rabies immunoglobulin]] are effective in preventing the disease if the person receives the treatment before the start of rabies symptoms. Washing bites and scratches for 15 minutes with soap and water, [[povidone-iodine]], or detergent may reduce the number of viral particles and may be somewhat effective at preventing transmission.{{cite web |title=Rabies Fact Sheet N°99 |url=https://www.who.int/mediacentre/factsheets/fs099/en/ |work=World Health Organization |access-date=28 February 2014 |date=July 2013 |url-status=live |archive-url=https://web.archive.org/web/20140401075427/http://www.who.int/mediacentre/factsheets/fs099/en/ |archive-date=1 April 2014}}{{cite book | vauthors = Wunner WH |title=Rabies: Scientific Basis of the Disease and Its Management |date=2010 |publisher=Academic Press |isbn=978-0-08-055009-1 |page=556 |url=https://books.google.com/books?id=C-U1LFK5zagC&pg=PA556}} {{As of|2016}}, only fourteen people were documented to have survived a rabies infection after showing symptoms.{{cite journal |vauthors=Manoj S, Mukherjee A, Johri S, Kumar KV |title=Recovery from rabies, a universally fatal disease |journal=Military Medical Research |volume=3 |issue=1 |pages=21 |year=2016 |pmid=27429788 |pmc=4947331 |doi=10.1186/s40779-016-0089-y |doi-access=free }}{{cite journal | vauthors = Weyer J, Msimang-Dermaux V, Paweska JT, Blumberg LH, Le Roux K, Govender P, Coertse J, Markotter W, Nel LH | display-authors = 6 |title=A case of human survival of rabies, South Africa |journal=Southern African Journal of Infectious Diseases |date=9 June 2016 |volume=31 |issue=2 |pages=66–68 |doi=10.1080/23120053.2016.1128151 |language=en |issn=2312-0053|doi-access=free|hdl=2263/59121 |hdl-access=free }} However, research conducted in 2010 among a population of people in [[Peru]] with a self-reported history of one or more bites from [[vampire bat]]s (commonly infected with rabies), found that out of 73 individuals reporting previous bat bites, seven people had rabies virus-neutralizing [[antibodies]] (rVNA).{{cite journal | vauthors = Gilbert AT, Petersen BW, Recuenco S, Niezgoda M, Gómez J, Laguna-Torres VA, Rupprecht C | title = Evidence of rabies virus exposure among humans in the Peruvian Amazon | journal = The American Journal of Tropical Medicine and Hygiene | volume = 87 | issue = 2 | pages = 206–215 | date = August 2012 | pmid = 22855749 | pmc = 3414554 | doi = 10.4269/ajtmh.2012.11-0689 }} Since only one member of this group reported prior vaccination for rabies, the findings of the research suggest previously undocumented cases of infection and viral replication followed by an abortive infection.

The cellular membrane pinches in a procession known as [[pinocytosis]] and allows entry of the virus into the cell by way of an [[endosome]]. The virus then uses the acidic environment, which is necessary, of that endosome and binds to its membrane simultaneously, releasing its five proteins and single-strand RNA into the cytoplasm. [63] => [64] => Once within a muscle or nerve cell, the virus undergoes replication. The L protein then transcribes five mRNA strands and a positive strand of RNA all from the original negative strand RNA using free nucleotides in the cytoplasm. These five mRNA strands are then translated into their corresponding proteins (P, L, N, G and M proteins) at free ribosomes in the cytoplasm. Some proteins require post-translational modifications. For example, the G protein travels through the rough [[endoplasmic reticulum]], where it undergoes further folding, and is then transported to the [[Golgi apparatus]], where a sugar group is added to it ([[glycosylation]]). [65] => [66] => When there are enough viral proteins, the viral polymerase will begin to synthesize new negative strands of RNA from the template of the positive-strand RNA. These negative strands will then form complexes with the N, P, L and M proteins and then travel to the inner membrane of the cell, where a G protein has embedded itself in the membrane. The G protein then coils around the N-P-L-M complex of proteins taking some of the host cell membrane with it, which will form the new outer envelope of the virus particle.

This stage is often known as "furious rabies" for the tendency of the affected animal to be hyper-reactive to external stimuli and bite or attack anything near. In some cases, animals skip the excitative stage and develop paralysis, as in the third phase; the paralytic phase. This stage develops due to damage to [[motor neuron]]s.

About

It is caused by the rabies virus, which belongs to the family Rhabdoviridae. Once symptoms appear, the disease is almost always fatal. The symptoms of rabies include fever, headache, muscle aches, and confusion, which progress to more severe stages such as hallucinations, paralysis, and hydrophobia (fear of water). The virus spreads from the initial site of infection to the brain and other organs, causing inflammation and damage. Rabies is found worldwide, except in a few countries such as Australia and Antarctica. It primarily affects mammals, including domestic dogs, bats, raccoons, and foxes, although any mammal can become infected. Dogs are the main source of transmission to humans, accounting for over 99% of cases. Preventing rabies involves vaccinating domestic animals, implementing animal control measures, and educating the public about potential risks. Once a person is exposed to rabies, immediate medical treatment is necessary to prevent the infection from becoming fatal. Post-exposure prophylaxis, which includes a series of shots, is highly effective if administered promptly. Historically, rabies has been a feared and misunderstood disease, often associated with myths and legends. It has been the subject of extensive research and study, leading to the development of vaccines and improved understanding of its transmission and prevention. The Wikipedia page on rabies provides detailed information on the disease, including its history, epidemiology, symptoms, diagnosis, treatment, and prevention. It also covers various aspects such as the social and cultural impact of rabies, notable cases, and ongoing efforts to control the disease globally.
