Daysha Berry Berry Grade 8 Science Mr. Loewen 5 December 2016 Period 1 Outbreak In Siberia Last July, a unquestioned illness came from Yamal Peninsula on a cold region of the northwestern Siberia, a part of Russia. Few weeks later, the sickness wiped out more than 2,000 reindeer in just a month. Hundreds or thousands of people are infected and being hospitalized After a couple of days of treating a 12 year old boy who had a fever and was vomiting had died.The illness is called Anthrax a deadly virus that can cause sores on skin, stomach problems, and pneumonia, an inflammation of lungs. The Yamal Peninsula is located
The Demon in the Freezer by Richard Preston is an intriguing book that discusses the anthrax terrorist attacks after 9/11 and how smallpox might become a future bioterrorist threat to the world. The book provides a brief history of the smallpox disease including details of an outbreak in Germany in 1970. The disease was eradicated in 1979 due to the World Health Organization’s aggressive vaccine program. After the virus was no longer a treat the World Health Organization discontinued recommending the smallpox vaccination. In conjunction, inventory of the vaccine was decreased to save money. The virus was locked up in two labs, one in the United States and one in Russia. However, some feel the smallpox virus exists elsewhere. Dr. Peter Jahrling and a team of scientists at the U.S. Army Medical Research Institute of Infectious Diseases in Maryland became concerned terrorists had access to the smallpox virus and planed to alter the strain to become more resistant. These doctors conducted smallpox experiments to discover more effective vaccines in case the virus were released. Preparedness for a major epidemic is discussed as well as the ease with which smallpox can be bioengineered.
In 1994, a stable in Hendra, a suburb of Brisbane, Queensland, Australia broke out with an unknown respiratory disease that resulted in thirteen horses and one horse trainer severely ill, resulting in death. [7, 8] This disease was isolated by scientists and later classified as the Hendra virus. The Hendra virus (HeV), previously unknown, is now classified under the family Paramyxoviridae, genus Henipavirus along with its sister viruses the Nipah Virus and Cedar virus.[7, 9] HeV has the capability of causing fatal diseases in several animal species including humans.[1] The primary host of the Hendra virus was identified as the flying fox species from the genus Pteropus[1,2,3] that resides and migrates through Northeastern Australia[8] or more specifically, the East coast of Australia to Melbourne and west across Northern Australia to Darwin[7].
The 2001 anthrax attacks was one of the worst bio-weapon attacks on the US in history. The attacks where done through the mail. The anthrax was placed in envelopes with a letter and mailed from various locations to different people and organizations. The anthrax filled letters ended up killing 5 people, causing 17 to become sick and exposing anthrax it is believed to as many as 30,000 people. During the mail process spores of anthrax from the letters escaped and got on mailroom equipment exposing postal employees. If a person was exposed to enough anthrax and developed symptoms they typically died in a few days. Postal workers during the attacks where told that anthrax will appear as a white powder t...
If an outbreak of anthrax were to occur it would probably happen in a form of an aerosol device of anthrax spores. The intentional bioterrorism outbreak would result in multiple cases of inhalation anthrax. If the outbreak was done by an aerosol can, there would be no indication of an attack because the United States, or anywhere else for that matter, does not have any appropriate method of detection for odorless, colorless, and tasteless spores of anthrax. This outbreak would cause the certain death of the first infected, since physicians in the U.S. would probably not detect anthrax as a cause of the patient’s flu-like symptoms. Most U.S. doctors and radiologists and lab personnel have not seen a form of inhalation anthrax and would not be able to identify it or notice Bacillus anthracis in a blood culture. Since an outdoor release of these spores can travel multiple miles and it only takes one gram to kill 10 million people, it could quite possible create extremely high fatality rates. In one city alone it is estimated that the release of aerosol anthrax could cause the death of up to 3 million people within the first couple of weeks.
From 166 A.D. to 180 A.D., The Antonine Plague spread around Europe devastating many countries. This epidemic killed thousands per day and is also known as the modern-day name Smallpox. It is known as one of deadliest plagues around the world.
Bacillus anthracis or anthrax is bacteria that infect thousands of people a year worldwide. Mostly found in the hinds and hair of grazing animals like cattle and sheep, the bacteria can stay dormant for years until contacted. Contact can occur through broken skin, eating infected meat, or inhaling infected dust from hides through the mouth or nostrils. Normal contact through the skin begins forming malignant skin ulcers that are dark black in appearance. If left untreated, the blisters lead to blood poisoning and eventually death. Eating contaminated meat not fully cooked can cause intestinal infection also leading to death. Surprisingly, many people survive contact of the skin and very few cases of intestinal infection exist. However, inhalation of infected dust or spores are much more deadly because the symptoms resemble a common cold...
Samples of tissue from patients infected with the mysterious disease were sent to the CDC Special Pathogens Branch for analysis. After a few weeks and several tests, the virologists linked the disease with an unknown type of hantavirus. Because other hantaviruses were known to be transmitted to people by inhalation or ingestion of rodent feces or urine, our next task was to collect as many species of rodent in the area as possible in order to pinpoint the source of the virus (AMNH). While trapping rodents, we decided that it was worth the risk to not wear protective clothing or masks so as to avoid alarming residents of "The Four Corners" region (CDC). After testing approximately 1,700 rodents we had found a link--the prevalent deer mouse carried the unknown type of hantavirus. But why was this mouse suddenly infecting people in this region? I was becoming frustrated, my years of work in medicine were failing me and I couldn't figure out why these people kept getting sick.
Louis Pasteur, in 1881, discovered the anthrax vaccine. Anthrax is an infection caused by many bacteria cells called “Bacillus”. These bacteria make “spores” which have a protective shell. This disease is most common in farm animals. They live in soil, and affect domestic a...
Evidence pointed out that there were as many deaths in thinly populated areas as those areas that were highly settled and there were as many deaths in the winter as in the summer. The presence of fleas in winter months is highly unlikely. According to Twigg, a medical historian, tales were told that described death as occurring within three to four days after incubation which also was inconsistent with the three-phase stages of bubonic plague. (Cantor ) In some cases death occurred without the presence of fever or buboes. It was strongly speculated that anthrax, a cattle disease, could have been partially responsible for numerous deaths. Anthrax began with symptoms similar to bubonic plague. There were arguments for and against the idea that rodents and cattle were responsible for these deaths. Humans eating tainted meat from infected cattle explained how the cattle disease was transmitted to humans. Because of limited medical advances during that time period, it was not clearly determined whether bubonic plague and anthrax
Pandemics and epidemics are diseases that affect many people all over the world. They cause millions of deaths and leave many people sick. Most epidemics are contagious and spread very quickly. One kind of epidemic is the variola virus. Variola virus is most known by the name smallpox. it got it’s nickname from the small blisters that appear on the face and arms. Smallpox is believed to have originated in Egypt or Northeastern Africa about 10,000 years ago. It soon reached Asia during the middle ages and reached Europe in 700 A.D.In 18th Century Europe it killed about 400,000 people a year. In the 20th Century alone, it has killed about 300 million. This disease has also led to the downfall of the Aztec Empire and killed many royal figures from France, Russia and other countries.
Anthrax is a very real and dangerous threat to all people who come in contact with it. The bacterial infection is caused by the bacteriaium Bacillus anthracis. Anthrax is divided into three categories all are contracted in different ways. The first type is called Cutaneous Anthrax; this is where anthrax spores make contact with the skin. If there is a cut or a lesion then a person can be infected. Cutaneous Anthrax is the most common way to get anthrax, but is also the least lethal. The second type of anthrax is called Pulmonary Anthrax this is where a person inhales the spores of anthrax directly into the lungs. If this type of anthrax is left untreated it could lead to death. The third type of anthrax is called Gastrointestinal Anthrax, this form results from eating meat from animals that have been infected with the anthrax bacteria. This causes the intestinal tract to become infected and this from is almost always fatal. This particular mode of anthrax has never been seen in the United States.
Influenza, normally called “the flu”, the influenza virus causes an infection in the respiration tract. Even though the influenza virus can sometimes be compared with the common cold. It also can cause a more severe illness or death. During this past century, pandemics took place in 1918, 1957, and 1968, in all of these cases there where unfortunately many deaths. The “Spanish flu” in 1918, killed approximately half a million people in the United States alone. It killed around 20 million worldwide. The “Asian flu” in 1957, in the United States their 70,000 people died. In 1968 the “Hong-Kong flu” There where 34,000 deaths in the United States.
The symptoms were blisters of the skins with puss and bleeding with high fever. The government was very aware and thought they had a vaccine but the micro-organism morphed into another pathogen that was airborn and the previous vaccine was no
Borderline personality disorder is known to affect many individuals, but at what cost? This psychological concept reflects a person’s struggle to find identity because of others and how they view their own self-image. The “Borderline Personality Disorder” by the National Institute of Mental Health publicizes that “loss of emotional control can increase impulsivity, affect how a person feels about themselves, and negatively impact their relationships with others,” leading to long-term effects in the near future (National Institute of Mental Health). Depending on what a person may experience, this physiological concept can determine what or how many symptoms they develop. Let's say someone has trouble managing relationships with their peers and/or
Chicken pox is not an Entrée that is served at one’s family holiday dinner party. Chicken pox is an extremely contagious disease caused by the Varicella zoster virus. Chicken Pox is not a disease that is known to affect other animals or insects. Unlike other diseases, where human and other animal close interaction causes the exchange of virus and disease this disease did not come from a human-chicken interaction. The name chicken pox has been stuck for generations; there are many theories behind its name. Chicken pox could sneak up on its young victims in the form of an innocent touch, or by inhaling tiny particles from a cough, or sneeze which then enters the respiratory tract. Once the virus attaches itself to it gracious, and unwilling host cells it causes a crimson rash that could be located on different parts of the body. The rash is highly irritating which makes it almost impossible not scratch. In the United States each year about 5,000 to 9,000 people are hospitalized, and around 100 people die from the microbe Varicella zoster that causes chicken pox.
