Sydney Leanhart Dr. Wong Ecology 2 September 2016 Dear Governor, The Yosemite Plague is a disease which has been present in Central California for many years. This disease normally does not draw much attention or concern because the risk of a human catching it is very minimal. However, there has been a very large increase of cases where people have contracted this plague over the last two months. Whereas this plague normally only affects five people or so a year. It is not very common for humans to contract this plague, but every so often it happens. The problem is this disease has been contracted much than usual during these past few months. In the past two months twelve people have contracted this disease, which is more the yearly average. …show more content…
This plague is bacterial, which means that it is easily treated with antibiotics. The key to being able to survive this plague is being able to recognize the symptoms early on, so you can get treated. If any person were to experience any symptoms of this disease, they should immediately seek treatment. If anyone starts to see signs of this disease after they visit the Yosemite National Park, I urge that they seek medical treatment immediately. Many of the symptoms related to this disease are chills, nausea, fever, swollen lymph nodes, headaches and weakness. However, different strains of this plague can produce a variety of symptoms. Anyone who visits Yosemite National Park should be on the lookout for these symptoms for a few weeks after visiting. If this plague is not treated immediately, it can be fatal. Through much scientific research, a bacteria called Yersinia Pestis was discovered. This bacteria is spread by both animals and insects. This specific bacteria attacks the lymph system causing the infection to spread throughout the body. The reservoirs of this bacteria and disease are mice, rats, squirrels and other small animals. A reservoir is a host of an infection. The vector, meaning carrier, is insects such as fleas and …show more content…
With the CDC there the number of people contracting the plaque should go down. The CDC should find ways to eliminate the plaque, while leaving the park open for guests. They should also so research on which insecticides work best to eliminate the plaque and the insects causing it. Many steps need to be taken to raise awareness of the plaque. The Yosemite National Park should air commercials informing the public about the plaque. These commercials should include information such as the symptoms of the plaque, what to do if you contract the plaque and the risk of the plaque on human lives. I hope you agree with the statements I have made about the plaque and how it should be handled. I hope that you approve the course of action that I have provided for you. Feel free to contact me anytime with any questions or concerns relating to the above. An action plan needs to be implicated immediately to ensure the safety of the public. It left unacted upon many people will remain unaware of the problem and many people will continue to be infected. Respectfully Submitted, Sydney
Coccidioidomycosis Coccidioidomycosis (also called San Joaquin Valley Fever) is a disease caused by breathing in airborne fungus spores. CAUSES The spores that cause this disease come from the fungus Coccidioides immitis. This fungus only contaminates the soils of certain dry regions in the Western Hemisphere. In the U.S., this includes southwestern Texas and the southern regions of California, Arizona, and New Mexico.
The plague is most effective because in 1331, the plague broke out in three different country’s china, asia, and Europe. In the book of “Tiny Invader” it states that ,”As many as 200 million people died in the pandemic,”(P.248). The plague is caused by bacteria like viruses, bacteria is a type of germ that kills many people. If one person had the plague and you could catch it by caring for the person or touching them.

Plague infects both people and rodents. The transmission of the disease can infect the population faster via rodents. Fleas feeding on infected rodents can transmit the disease to people as well. Once infected, people can infect others by coughing, sneezing, or close talking. The origin of “The Black Death” dates to an outbreak in China during the 1330s.
The decline of population was a prominent aspect in the deadly epidemic. Physicians didn’t have any knowledge of the Black Plague, which made it difficult to cure and eliminate the disease. With the lack of information about the disease and how it started, it resulted in many people not being able to get cured: “perhaps either the nature of the disease did not allow for any cure or the ignorance of the physicians… did not know how to cure it; as a consequence, very few were ever cured…” (Bubonic Plague DBQ Doc. 1). There was no medicine for
This deadly disease killed millions of people and decreased the population in Europe, which caused the employment rate to go down significantly. This terrifying disease first started off with a severe headache, than they got the chills along with a high fever. With all of that you could only imagine how exhausted they would be. The next stage is when you start to feel extremely nauseous and start vomiting which lead to pain in their backs, arms and legs.
The black plague killed seventy-five through two hundred million people in 1347. Still, the black plague has taken place in recent times; the most recent case was October 22 2015 last year. The black plague was a pandemic that has been here for a long time. The black plague killed many people and was agonizingly painful, as it spread through Europe in an interesting and very fast way. To begin, the black plague was a terrible pandemic that caused many painful effects.
Plague of London Fall, 1664. Rumors of a plague in Holland have been circulating. More gossip had erupted that two men died of the same afflictions, in a small time frame, doctors came to inspect the bodies and confirmed they died of the same plague the supposedly came form Holland. They made a public announcement to confirming the rumors, that indeed the plague had made it to London. The two men where not the only ones to suffer from this, more started to die.
The Black Death also referred to as Bubonic plague, appears to have first occurred in the Central Asia in the early 1300s. The plague was disease that affects human and other mammals. It was caused by the bacteria, Yersinia Pestis. The plague is infamous for killing millions of people in Europe during the Middle Ages. The bacteria that causes plague, Yersinia Pestis, maintain their existence in a cycle involving rodents and their fleas.
My king, my trusted king oh how great and powerful you are. Leading us through victories the most suitable repayment I can offer you a chronicle about the Black Death. I am Greta Van Necklebriens a great, great, great grand-child of Guy de Chilliac. I have been studying the black death for 20 years and have gotten the books of Guy de Chilliac passed on to me.
days were examined because with each day the number of deaths was higher the previous day. Approximately 60% of the fatalities were women and with the exception of the elderly, the number of fatalities rises with the age of the infected (see figure 2) . It is suggested that women may have made up a greater percentage because they were usually at home and more prone to the risk of infection. There were other common diseases roaming, but the plague was one of the few diseases that could land devastating hits on communities and turn them into ghost towns within a matter of weeks. It might have been a particular point in time where there was a high number of plague deaths but not as much as the 1575 epidemic
The virulence of the plague bacillus—that is, its ability to multiply in the tissues of its host and cause death—is remarkably stable and vigorous. Once ingested by a flea, it multiplies until the insect’s digestive tract is blocked. When the flea bites another rodent or a human, bacilli are regurgitated into the new host and migrate through the lymphatic system to lymph nodes. There they are able produce proteins that disrupt the normal inflammatory response and that prevent their digestion by infection-fighting macrophages. With the host’s immune response thus weakened, the bacilli quickly colonize the lymph nodes, producing a painful swelling and, eventually, destroying the tissue.
The history of human beings saw very destructive pandemics known as the Black Death. It led to the death of millions of people, and reached its zenith in the years 1346-53 in Europe. The main reason behind it, still remains an unanswered question but the major cause is considered to be the pathogen named “Yesinia Pestis”which was found in the DNA of the victims. It was in the year 1343, when this plague reached Crimea through the oriental rat fleas which lived in the merchant’s ships. It established to kill 20-60% of Europe’s population.
Geography and domestic animal play a major role to the development of any plague. In places where there are a lot of cities plagues spread quickly since population increase as babies are born causing a cycle that makes plagues almost impossible to extinguish. Cities tend to growth domestics animals which is the reason why plagues emerge in the first place. In colonial cities people used to growth and frequently being in contact with cows, pigs, birds, etc. The contact with these animals and the lack of sanitation caused that humans contracted these deathly virus from them.
Humans usually get plague after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with plague. Plague is infamous for killing millions of people in Europe during the middle ages. Today, modern antibiotics are effective in treating plague. Without prompt treatment, the disease can cause serious illness or death. Presently, human plague infections continue to occur in the western United
