    My disease is Streptococcal pneumonia or pneumonia is caused by the pathogen Streptococcus pneumoniae. Streptococcus pneumoniae is present in human’s normal flora, which normally doesn’t cause any problems or diseases. Sometimes though when the numbers get too low it can cause diseases or upper respiratory tract problems or infections (Todar, 2008-2012). Pneumonia caused by this pathogen has four stages. The first one is where the lungs fill with fluid. The second stage causes neutrophils and red blood cells to come to the area which are attracted by the pathogen. The third stage has the neutrophils stuffed into the alveoli in the lungs causing little bacteria to be left over. The fourth stage of this disease the remaining residue in the lungs are take out by the macrophages. Aside from these steps pneumonia follows, if the disease should persist further, it can get into the blood causing a systemic reaction resulting in the whole body being affected (Ballough). Some signs and symptoms of this disease are, “fever, malaise, cough, pleuritic chest pain, purulent or blood-tinged sputum” (Henry, 2013). Streptococcal pneumonia is spread through person-to-person contact through aerosol droplets affecting the respiratory tract causing it to get into the human body (Henry, 2013).

    The main objectives of the pathogen are to gain entry inside the host, once inside grow and reproduce, and avoid host defenses. There are three possible routes of infection: respiratory, alimentary, and traumatic. The respiratory route is the easiest and most direct means of entry. Under crowded conditions, the rate of infection is even more rapid. The diseases brought over to America were mainly spread by the respiratory method. The alimentary pathway of infection is through the ingestion of contaminated food and water. Throughout Europe during the 15th century, food and water were contaminated with fecal matter and by unsanitary habits ( i.e. the lack of bathing). The traumatic route of infection is through insect and animal bites.

  • Blood Borne Pathogens and Disease Transmission

    989 Words  | 2 Pages

    Pathogens are a type of microorganism that spreads viral and bacterial diseases. These diseases when present in human blood and body fluids are known as blood borne pathogens, and can spread from one person to another. (Worcester polytechnic institute) The most serious types of blood borne diseases are the hepatitis B virus (HBV) and hepatitis C virus (HCV), which can cause liver damage; and HIV (human immunodeficiency virus), which is responsible for causing AIDS (acquired immune deficiency syndrome). The blood borne pathogens can be spread when the blood or body fluids (semen, vaginal fluid, breast milk, and amniotic fluid) of an infected individual comes into contact with mucous membranes or an open sore or cut on the skin of another person. Mucus membranes are located in the eyes, nose, mouth, and other areas as well. ("Bloodborne pathogens: MedlinePlus Medical Encyclopedia") Two of the most common ways that pathogens are transmitted is through the exchange of fluids during sexual intercourse or by sharing infected IV needles.

Most common assumptions have been that transmission has occurred through skin lesions or by sharing blood contaminated objects. Infected saliva is another source of infection especially as a non-parental infection. The virus has the ability to enter a healthy body as an airborne disease by coughing and sneezing, from mouth-to-mouth kissing, biting or by sharing chewed toys and candies [2, airborn]

    The cause of the influenza epidemic was discovered in the 1890 epidemic as the micro-organism named Bacillus influenzae and the culprit was first identified and cultivated during that epidemic. Although this organism is found in severe attacks of influenza, its presence may not be found in all cases of influenza, according to The Manchester Guardian Medical Correspondent. On Monday, July 1, some officials and citizens also suggested that the illness is caused by "abnormal atmospheric and climatic or meteorological conditions." "3 However, with a few days of observation and with the benefit of hindsight, the theory is discarded. Influenza failed to abate even after this week's consistent good weather.

  • Chain Of Infection Essay

    Recent research shows that, there are three major means by which infections can be transmitted and they include direct transmission, indirect transmission and airborne transmission (Hinman,Wasserheit and Kamb,1995). Direct transmission occurs when the physical contact between an infected person and s susceptible person takes place (division of public health, 2011). An example is a health care worker who attends to an Ebola patient, without gloves, gown and mask plus forget to wash his or her hand with soap and hot water and or a person having flu without the use of mask or washes his hand after sneezing easily passes the infection to the other through hand shake or surface touch, living the bacteria there for another vulnerable person to also touch if the surface is not disinfected with bleach. Studies makes it clear that, the spreads takes effect when disease-causing microorganisms pass from the infected person to the healthy person through direct physical contact such as touching of blood, body fluids, contact with oral secretion, bites kissing, contact with body lesions and even sexual contact. However, measles and chicken pox are said to be conditions spread by direct

  • Environmental Transmission of Pathogens

    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).

  • The Flu

    1097 Words  | 3 Pages

    The Flu was first founded in Seattle September, 1918. The avian flu can also be known as the “Bird Flu”. The bird flu is being passed around by migratory birds. It can be transmitted from birds to mammals and in some limited circumstances to humans. The flu will also be known as the H5N1 virus. The H5N1 virus has raised concerns about a potential human pandemic because its virulent (deadly; extremely dangerous) and it can evolve like other influenza viruses. As many other viruses and illnesses the flu can be a lot more deadlier. When you get the flu the lungs are severely harmed from infected cells called macrophages and T-cells. The virus can spread way beyond the lungs but generally do not. Many people catch the flu and think they have the common cold because of some of the same symptoms. But actually the flu can be more dangerous if you don’t treat it immediately.

  • Essay On Swine Influenza

    1165 Words  | 3 Pages

    The swine influenza or swine flu is a respiratory disease in pigs that is caused by the type A influenza viruses. These viruses are referred to as swine flu viruses but scientifically the main virus is called the swine triple reassortant (tr) H1N1 influenza virus. When the viruses infect humans they are called variant viruses. This infection has been caused in humans mainly by the H1N1v virus in the United States. The H1N1 virus originates in animals due to improper conditions and the food they ingest. The virus stays in latency form, thus harmless to the respective animal. The longer the animals survive the more likely the virus is to develop and strengthen making it immune to vaccines. The virus reproduced through the lytic cycle. The virus injects its own nucleic acids into a host cell and then they form a circle in the center of the cell. Rather than copying its own nucleic acids, the cell will copy the viral acids. The copies of viral acids then organize themselves as viruses inside of the cell. The membrane will eventually split leaving the viruses free to infect other cells.
