1. Anywhere you go you will always come in contact with an area that has been contaminated by something. This can be from someone’s dirty hands from poor hygiene to the mold that we are unaware that we are breathing in. But what about that fresh air you are breathing when you go on that hike in the woods? According to the CDC (2012), the airborne virus Hantavirus (HPS) can be located in areas such as forests, fields, and farms. This virus comes from rodents, so you may find this in the air in any habitat that is suitable for them to live. In 1993 the first case of HPS was reported to the United States as well as other countries and since then there have been studies done to see what type of specific environment is the cause of this virus (Riquelme, R., Rioseco, M. L., Bastidas, L., Trincado, D., Rquelme, M., Loyola, H., & Valdivieso, F. 2015). This outbreak first happened in the Four Corners area in the southwestern United States and was originally named “Four Corners virus” however, local authorities complained about the name and the name “Sin Nombre” was later adopted (Spanish for no name) (Tortora G.J., Berdell F.R., Christine C.L 2013). Early symptoms of …show more content…
HPS is an emerging virus that is transmitted to humans by coming in contact with a rodent that is infected with the virus. Once this virus is transmitted to humans it can cause two different types of clinical syndromes, hemorrhagic fever with renal syndrome (HFRS) or hantavirus cardiopulmonary syndrome (HCPS) (Kruger D., Schonrich G., Klempa B. 2011). When you are first infected with HPS it doesn’t cause your Dendritic cell (DC) to have a loss in function, however, it will initiate in your immune system. When you are infected the HPS it induces your DC to maturation then uses the DC to serve as a vehicle to migrate to the regional lymph nodes once the infected DC reach this area the immune response will be to release virus-specific antibodies and T cells according to Kruger D., Schonrich G., Klempa B.
This extremely pathogenic zoonotic virus is now understood to travel from bat species, to equine intermediate hosts, to humans.[8, 10] The Hendra virus is listed as a Bio-Safety Level (BSL)-4, and can only be studied at a few adequately equipped laboratories worldwide due to its virulence.[1, 2] Case fatality rates
Some cases are severe and patients can develop hemolytic uremic syndrome, or HUS, which is a type of kidney failure. There have been no cases of HUS or deaths from this outbreak.

The medical field is a vast land of beauty, but with great beauty comes immense horror. There are many deadly viruses and diseases found in the medical field. In the novel, The Hot Zone by Richard Preston, the author discusses the many deadly viruses found in the field. The viruses are widespread due to the errors that occur when the viruses are in the presence of human beings. The effects of the errors performed by the human race include a decrease in population and wildlife.
The Panic Virus: A True Story of Medicine, Science, and Fear written by Seth Mnookin offers something for all potential readers. For those who are anti-vaccine, Mnookin offers valid science, testimony, history, and excerpts that demonstrate that vaccinating a child can be more beneficial than not. Instead of simply dismissing those who do not vaccinate their children, Mnookin offers valid points to counter argue in this debate. Mnookin offers thought, logic, reasoning, and research into his arguments, showing that his opinion is rooted in fact, rather than opinion or belief. Those who are on the fence about vaccination may find this book useful in that Mnookin not only offers plenty valid points about pro-vaccination, however, he also provides

Also known as Coccidioidomycosis, Valley fever infections have been on the rise in recent years. Endemic to the desert Southwest, valley fever is caused by the soil-dwelling fungus Coccidioides. The cocci get stirred up by building, drilling, tilling, and clearing land, and disperse due to dry, hot, windy conditions. The spores may be inhaled and are capable of embedding deep into the lungs. Valley fever cannot spread from person to person.
Polio is a viral disease. It cripples thousands of people and infects even more every year. Even though millions are inoculated, and the polio disease has been successfully purged from hundreds of countries still thousands of people and developing countries are infected and still people are dying. According to the World Health Organization (WHO) polio affects the Central Nervous System, or CNS; by infesting the intestines and transmitting it into the nerves thought the blood vessels. There the virus spreads through the nerve cells to the brain stem or other motor units, while forever damaging the nerves.
Valley fever is a fungal pathogen. Coccidioidomycosis is valley fever’s scientific name. The pathogen’s structure is a spore. Valley fever is caused by Coccidioides immitis. Coccidioides immitis is a fungus that grows in soil. Valley fever is most commonly found in areas with little precipitation. This pathogen is most commonly found in the southern United States, Central America, and South America. However, scientists are worried that increased temperatures may cause valley fever to spread and affect new areas.
The virus is primarily spherical shaped and roughly 200nm in size, surrounded by a host-cell derived membrane. Its genome is minus-sense single-stranded RNA 16-18 kb in length. It contains matrix protein inside the envelope, hemagglutinin and neuraminidase, fusion protein, nucleocapsid protein, and L and P proteins to form the RNA polymerase. The host-cell receptors on the outside are hemagglutinin and neuraminidase. The virus is allowed to enter the cell when the hemagglutinin/ neuraminidase glycoproteins fuse with the sialic acid on the surface of the host cell, and the capsid enters the cytoplasm. The infected cells express the fusion protein from the virus, and this links the host cells together to create syncitia.
HAV is known to be an infectious disease that usually occurs in children and young adults .The disease is usually transmitted from person to person through contaminated food, liquids or oral fecal route. An example would be when someone is carrying the virus and doesn’t wash their hands after using the restroom and then puts food in their mouth. HAV is most common in developing countries because of the living conditions and inadequate water, poor sewage facilities and sanitary conditions. The highest HAV levels in the world are from India,” Earlier reports suggest that India is hyperendemic for HAV infection2,4-6 with very high infection rates,” (Sowmyanarayanan). Most HAV are without severe complications, “Virus HAV infection rarely causes fulminant hepatic failure in people…,” (Vento,p.1) . The symptoms for HAV are high fever, nausea, vomiting and jaundice...
Valley fever is transmitted when bacteria in the soil become airborne and are inhaled. California residents must understand the harmful effects of air pollution and make better choices when using energy or transportation. The drought conditions are worsening, but communities and individuals can work together to help improve the air quality. References California drought and air quality Santa Barbara County air pollution control district. (2015).
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.

There are 5 main pathways of environmental transmission of pathogens. Those are air-borne, food-borne, water-borne, vector-borne and blood-borne. Air-borne transmission refers to any disease that is caused by a pathogen and transmitted through the air. These pathogens can be spread by coughing, sneezing, stirring dust, liquid spraying, or generally any activity that generate aerosol particles or droplets. These pathogens can include viruses, bacteria, or fungi. Some common examples of pathogens that are spread via air-borne transmission are rhinovirus, hantavirus, adenovirus, and influenza, among many others (cdc.gov).
