Communicable disease outbreak - HAT Task 3
Analyze the selected communicable disease outbreak: SARS
Disease overview
Severe acute respiratory syndrome (SARS) is a viral respiratory illness caused by a coronavirus, called SARS-associated coronavirus (SARS-CoV). According to the Centers for Disease Control and Prevention, the illness begins with a high fever (greater than 100.4 degrees F). The fever is sometimes associated with chills or other symptoms, including headache, general feeling of discomfort, and body aches. Some individuals experience mild respiratory symptoms at the outset. Diarrhea is seen in approximately 10 to 20 percent of patients. After 2 to 7 days, SARS patient may develop a dry, nonproductive cough that might be accompanied by hypoxia. In 10 to 20 percent of cases, patients require mechanical ventilation. Most patients develop pneumonia. The disease is spread by close person-to-person contact through direct contact with respiratory secretions and/or body fluids of an infected individual. The incubation period is typically 2 to 7 days, but there are reported cases of up to 14 days. An individual is considered infectious only when they have symptoms, and are considered most contagious during the second week of illness. (Centers for Disease Control and Prevention, 2005)
According to the World Health Organization (WHO), in November 2002 a SARS outbreak emerged in South China. An infected medical doctor who had treated infected patients in his hometown in South China traveled to a four-star hotel in Hong Kong, bringing the disease with him. Within days, guests, employees and visitors of the hotel were showing signs of the infection. The disease was simultaneously spreading around the world along international travel routes as guests of the hotel traveled home to Viet Nam, Singapore, Taiwan, Toronto, all of which became infection hot zones. The attached map provides a geographical graphic of the international pattern of the outbreak. The outbreak resulted in a total of 8,098 people with severe acute respiratory symptoms accompanied by either pneumonia or respiratory distress, of those with symptoms, 774 died. By late July 2003, no new cases were reported and the WHO declared the crises over. In the United States, only eight persons were confirmed as SARS cases, and none of these individuals died. All eight of these people had traveled to areas where SARS-CoV was occurring. (World Health Organization, 2003)
Transmission
The pattern of spread of SARS-CoV is primarily through droplets and close personal contact. The CDC has determined that infected persons do not transmit SARS-CoV “before the onset of symptoms and that most transmission occurs late in the course of illness when patients are likely to be hospitalized.”("SARS Core Document," 2005, Appendix 1)
Incubation Period
Many countries reported median incubation periods of four-five days, and a mean of four-six days, with China and Singapore reporting a maximum of fourteen days. The WHO has recommended the application of a maximum incubation period of ten days, based on the 2003 SARS outbreak. (Kutsar, 2004)
Period of communicability
Based on the 2003 SARS outbreak, specifically the cases in Singapore, severely ill patients present the highest communicability during the second week of disease and when isolated within five days of the disease onset rarely provided the opportunity for secondary cases occurring. The WHO guidelines state that there is no data of communicability or infectious agent transmission after 10 days following the resolution of fever. (Kutsar, 2004)
How would a SARS outbreak affect my community?
A SARs-type outbreak, similar to the 2003 SARS Global outbreak, has a high probability in my community due to its metropolitan nature and it’s location within sixty miles of both New York City and Philadelphia. New Jersey’s Department of Health requires health care providers within the State to report cases of communicable diseases to their local health departments once the diseases are confirmed or suspected. If a suspected case of SARS, or one of the other critical diseases is identified, a medical provider must contact their local Department of Health via telephone immediately. Depending on the severity of the symptoms, the health department would investigate the individual and where/how the disease was contracted, who that individual has been in contact with and determine whether the individual must be hospitalized and quarantined. My community participates in a rapid notify emergency notification system, where broadcast telephone, web and email broadcasts would be sent to provide emergency public information messages. Depending on the severity of the disease and the size of the outbreak, the local health department would work in cooperation with the State Department of Health, the Centers for Disease Control and Prevention, as well as the medical professionals and medical facilities in the area.
A SARS case has been identified, explain the appropriate protocol for reporting the possible outbreak.
New Jersey has developed an electronic, web-enabled system where public health partners statewide an instantly report and track incidences of communicable diseases. The Communicable Disease Reporting and Surveillance System (CDRSS) is available 24 hours a day, 7 days a week and weekly transmissions to the Centers for Disease Control and Prevention (CDC) support national as well as statewide surveillance. ("CDRSS," 2012) Individuals who are employed in a public health occupation have access to the system. If a disease has been identified as an “immediate reportable” (such as SARS), then the medical professional must contact the New Jersey Department of Health immediately via telephone. All healthcare providers are required by New Jersey Administrative Code, Title 8, Chapter 57 to report specific communicable diseases. ("CDRSS," 2012) Once the Department of Health has been notified, isolation and quarantine procedures would be initiated if necessary. The Department of Health will contact the infected individuals immediately and begin an investigation, triage, treatment, containment, public communication, etc.
Poor air quality index is poor, as the community health nurse how would you modify the plan of care for those with asthma and other respiratory diseases
When meeting with patients who suffer from asthma it is important to educate and provide planning initiatives to help them lessen the chances of a potential asthma crisis. All asthmatics should have an asthma action plan that has been reviewed with their doctors in preparation for managing any respiratory crisis. “Poor air quality caused by a combination of ground-level ozone and air pollution can worsen asthma symptoms, triggering wheezing, coughing, trouble breathing, and even leading to hospitalization in serious cases. Newspapers, websites, and TV news broadcasts often warn of so-called "ozone-advisory," "ozone-alert," or "ozone-action" days, when sensitive groups—those with asthma and other respiratory conditions—should stay indoors because potentially dangerous smog conditions are likely.”("4 ways to stay safe," 2010, para. 1)
The first strategy that asthmatics should initiate on those ozone-alert days is to try to stay indoors, keep windows closed at home or in the car, restrict outdoor activities to times of the day when air quality is better (usually in the morning and evening hours) and check air quality forecasts by monitoring their local weather and air quality forecasts online. If asthmatics also suffer from allergies, such as tree pollen, etc., that may be trigger an asthma crisis, they should consider wearing an allergy facemask when they must venture outside. They should also change their clothing immediately upon entering their homes after being outside and washing or containing that clothing immediately so that those allergens are not shed inside. Asthmatics should always have their asthma medications nearby, especially their rescue inhaler. It is important to take all of their preventative medications, such as Advair or Flovent, as prescribed. All medications should be checked for expiration dates to ensure effectiveness. Finally, they should stay hydrated and breathe properly. Lungs like the right temperature and right amount of hydration. Breathing should be through the nose, not through the mouth. The nose must filter the air and bring it to the correct temperature and humidity prior to the delivery to the lungs. When breathing through the mouth this process does not occur, causing the lungs additional stress on the lungs. ("4 ways to stay safe," 2010) References

People's health is affected by how much money, power and resources that they have, how much education a person obtains, what kind of work a person does, how a person develops early childhood, etc. These are factors that are related to health outcomes by social determinants of health. 2. The social determinants of health contribute to the development of illness. For example, when a person was born in economically poor family and malnourished, malnutrition cause many health and developmental problems including growth retardation, increased risk of infectious disease, premature death, delayed mental development, and poor school performance( Maurer & Smith, 2009). 3. A communicable disease chain include agent(pathogen), reservoir, portal of exit, mode of transmission, portal of re-entry, and susceptible host. A communicable disease are spread by a chain of events that is all interconnected. Pathogens are viral, bacterial, parasitic and fungal. Methods of transmission include mucus, blood, breath, saliva and sexual contact. Contaminated surfaces, such as doorknobs, counter tops and playground equipment, provide a medium for passing disease from one human to another(Anderson, 2011) 4. All health caregivers including nurses have a responsibility to break the chain in any steps so that infections may not occur...

Communicable diseases are diseases that can be passed from one person to another just by everyday communication. Communicable diseases are the easiest to spread amongst our population. Dermatophytes are a type of communicable disease that could be spread to anyone. Dematophytes are fungi that cause skin, hair, and nail infections and are often known as ringworms. One example of a very common dermatophyte infection is athlete's foot, which is also called tinea pedis. Another common dermatophyte infection affecting the groin area is jock itch, also known as tinea cruris. There are many different species of dermatophytes that can cause infection in humans. Two of the most common types are Trichophyton tonsurans, and Trichophyton rubrum and these are usually transmitted from person to person. Another common dermatophyte is Microsporum canis, and that is transmitted from animals such as cats and dogs to humans. Dermatophytes like to live on moist areas of the skin, like the places where there are skinfolds. They can also live on household items, including clothes, towels, and bed sheets and so on.

...Gastroenteritis in Saint Louis, Missouri Megan O’Heron HCS/457 Lindsay Coogan Vomiting, diarrhea, abdominal cramping, maybe even a fever, and you might think you have the stomach flu. As modern medicine has progressed we have come to find that no such thing exists. A common occurrence caused by viral or bacterial infections, gastroenteritis sweeps through communities giving these symptoms to individuals and being dubbed the stomach flu. Saint Louis, Missouri is no different and had its worst breakout of this particular communicable disease back in 2013. The local health department continues to raise awareness of the prevention measures and what the community can do moving forward. Gastroenteritis is a communicable disease that affects the gastro-intestinal tract. It causes inflammation within the intestines that can causes symptoms like watery – usually non-bloody – diarrhea, abdominal cramps, nausea and vomiting, occasional muscle aches and headaches, and low-grade fevers (Mayo Clinic, 2015). “Depending on the cause, viral gastroenteritis symptoms may appear within one to three days after you’re infected and can range from mild to severe. Symptoms usually last just a day or two, but occasionally they may persist as long as ten days” (2015). You are most likely to contract viral gastroenteritis when you eat or drink contaminated food or water, or if you share utensils, towels or food with someone who is infected. A number of virus can cause gastroenteritis, such as: norovirus...

This communicable disease is cause by a virus called varicella-zoster which has a resemblance with the herpes virus. It can be transmitted through close contact with the fluids from the blisters or through air wherein the virus is disseminated by coughing or sneezing. Chickenpox is regarded as highly communicable for individuals who are exposed to the disease for the first time has an 80% risk of acquiring the disease through close contact of an infected individual. As claimed by the Pub Med Health, “most children with chickenpox exhibit symptoms like fever, headache, stomach ache, loss of appetite, or presence of small, fluid-filled, itchy, red spots over the skin.” At the time when the chickenpox blisters has dried and formed scabs is the point where the individual isn’t contagious. Each and every individual is at risk of being infected by chickenpox – no exception. It is known to have life threatening effects. As the Directors of Health Promotion and Education states, “in the United States, 4,000 to 9,000 individuals are hospitalized annually with chickenpox, with approximately a hundred casualties. Those at highest risk for complications are newborns, individuals with compromised immune system, and adults.” As chickenpox is caused by a virus, it has no cure and the virus would remain in our system for a lifetime even after we’ve done exhibiting the signs...

...Communicable Disease: Chickenpox Grand Canyon University: NRS 427v December 10, 2014 Communicable Disease: Chickenpox The Centers for Disease Control and Prevention (2010) defines a communicable disease as “an illness caused by an infectious agent or its toxins that occurs through the direct or indirect transmission of the infectious agent or its products from an infected individual or via an animal, vector or the inanimate environment to a susceptible animal or human host.” There are numerous communicable diseases being studied, treated, prevented, and diagnosed around the world. For the purpose of this paper, one communicable disease in particular will be examined, chickenpox. This paper will address chickenpox as a communicable disease, determinants of health leading to chickenpox, how chickenpox relates to the epidemiologic triangle, the role of the community nurse in their treatment and prevention of chickenpox, and organizations involved on the national level. Epidemiology Chickenpox is a reaction to a virus by the name of varicella-zoster virus. The varicella-zoster virus is also known to cause a reaction called shingles later in the adult life. Chickenpox causes patients to have an itchy blister-like rash. Other symptoms that are a fever, sleepiness, decrease in appetite, and headache (Centers for Disease Control and Prevention [CDC], 2012).

Communicable Disease- Dermatophytes

...A communicable disease is an illness transmitted through contact with one person, animal, food, surface, and air to another. The exchange of fluids or contact with a contaminated substance or individual may be enough to allow a communicable disease to spread. Communicable diseases are all-around but to avoid getting infected with one, people should follow prevention guidelines. There are many communicable diseases but a familiar one is dermatophytes, better known as ringworm, infect the skin, hair, or nails of a person. To control it people should practice good hygiene. Environmental factors, which are related to dermatophytes, are mostly human-to-human contact and human-to-animal contact. To reduce the spread of the ringworm, public health departments give tips to everyone on how to prevent and treatments to kill the infection. Dermatophytes, also known as ringworm or tinea, are fungi that cause infection to skin, hair, and nail. A common dermatophyte infection is athlete's foot and jock itch. The disease usually spread outward with progress and itches. The infection causes redness, cracking, and patches that may blister among the skin. “Ringworm of the scalp typically begins as a small pimple that expands with time, leaving scaly patches of temporary baldness. Infected hairs become brittle and break off easily. Occasionally, raised moist and draining lesions can occur. When finger/toe nails are affected, the nails become thickened, discolored, and brittle, or they may become...

...Communicable Disease Paper While it has not claimed the number of lives that some more prominent communicable diseases have, the Ebola virus remains one of the most feared diseases the planet has ever known. Ebola is the subject of much attention from Hollywood; Ebola outbreaks quickly become public knowledge, and always have the potential to cause a panic. Ebola is a hemorrhagic fever, which causes victims to have a difficult time coagulating blood cells. (Bardi, 2002) The results are gruesome, with the afflicted suffering greatly and rarely surviving. Due to the devastating potential Ebola holds, efforts to control it are unprecedented. Nongovernmental organizations like the World Health Organization are often on the scene of a potential Ebola outbreak within days, working to ensure that the disease does not spread beyond the Ground Zero outbreak. The known outbreaks of Ebola have occurred in African countries like Zaire, predominately because of environmental factors. While it is a brutal killer, Ebola is not an especially hardy specimen; it is very easily killed by the cold, and thus is found in the warm and semi-tropical climates noted in Africa. (Waterman, 1999) In addition, researchers have determined that Ebola is probably carried by monkeys, which are in abundance in Africa; Europe and the United States lacks significant monkey populations, which limits the potential for an outbreak to occur there. Additional factors for why the Ebola virus tends to pop...
