Science or Science Fiction? Their Eyes Were Watching God: Topic of Rabies Student
The Reel• Reel: In the movie the character, Tea Cake, was bitten by a rabid dog while trying to keep it from biting his woman, Janie, and he contracted the rabies.• In the onset of symptoms the site of the bite itched, he was weak, and was unable to swallow.• As the symptoms progressed he exhibited signs of agitation, hyper salivation, blurred vision, delirium, confusion, and excitation. A doctor visited and warned that without the proper medication and being tied down the virus would lead to death.• The character’s symptoms increased and led to hallucinations. In the end he was killed when he tried to shoot Janie due to the delirium.
Lyssavirus rabies• Rabies is a virus.• Transmitted through a bite or by saliva or brain tissue in a wound or in the eye or mouth (4).• Very rare, but has been transmitted through infected saliva in the air (1).• Attacks the nervous system and kills almost any mammal or human that gets sick from it.• Death can occur within days in which the virus can last from 2-10 days.• 1 to 3 people die in the U.S. every year (4).
Incubation Period• This is the actual time between getting infected and when you get sick• On average it is from 3-7 weeks• At the most this period ranges from 10 days to 7 years (1).
Symptoms• The early symptoms can mimic the onset of the flu.• As it progresses: insomnia, anxiety, confusion, slight or partial paralysis, excitation, hallucinations, agitation, hyper salivation, difficulty swallowing, and hydrophobia.• These symptoms stem from cerebral dysfunction and cause abnormal behavior and delirium (4).
Two Forms Furious Paralytic• Symptoms: • Accounts for 30% of human hyperactivity, excited cases behavior, hydrophobia, and • Runs a longer course than sometimes aerophobia furious rabies• Death is caused by cardio- • Symptoms: muscles respiratory arrest paralyze at the site of the bite or scratch, coma develops, and then death occurs • This form of the disease is often misdiagnosed due to it not being reported (5).
Diagnosis• Person is asked a series of questions to get the proper information for the diagnosis and animal-control authorities (3).• If the animal is caught (brain) tissue samples are taken• Immunofluorescence or immunological techniques to detect the virus in the tissue or saliva of the animal or if the person has severe symptoms
Animals that can spread the virus• Bats• Foxes• Cats• Dogs• Skunks• Large rodents• Raccoons• CoyotesDogs cause 99% of human rabies deaths. Bats are the source of most human deaths in the U.S. and in Canada (5).
Treatment• Immediately clean the wound with soap and water• Given within 12 hours of exposure• Given within 48 hours for the best outcome• Initially, the person will be treated with the rabies immune globulin near the site of the bite.• A series of 5 injections of the vaccine will be given in the arm over a period over 14 days (3).• Urgency is key!!!
Prevention• Administration of both passive antibody through an injection of human immunoglobulin and a round of injections with rabies vaccine (4).• Oral vaccines fed to wild animals• Government mandated vaccinations of animals• Avoiding contact with a suspected rabid animal
