Summary
Respiratory Syncyial Virus (RSV) is the most common infection of the upper and lower respiratory tract that infects children. It is prevalent around the world and usually causes only mild symptoms. Almost all children in the world are infected before the age of two (Goldrick 54).

RSV infection can spread within families, and outbreaks have occurred in schools and day care centers. According to Goldrick, "The incubation period for RSV infection is typically four to six days but may be as short as two or as long as eight days; children may shed the virus for two to three weeks" (54). Infection usually results in a mild cough and cold like symptoms as the virus infects the upper respiratory tract. When the infection spreads to the lower respiratory tract, it can result in difficult breathing, wheezing, bronchiolitis, and pneumonia.
Diagnosis is based on observing the symptoms and may be confirmed by isolation and examination of RSV secretions, sputum or throat swabs. "Rapid diagnosis may be made by immunofluorescence techniques, enzyme immunoassays, or rapid chromatographic immunoassays" (Pruitt 63). If a patient tests positive for RSV, it should delay inappropriate antibiotic therapy.
Mild infections may resolve without the need for treatment. However, severe infections, especially in children and infants, "may require hospitalization to provide supplemental oxygen, humidified air, and hydration by intravenous fluids" (Goldenring). Nebulised and subcutaneous adrenaline have been effective in improving oxygenation and have shown positive clinical signs as compared to a placebo (Stack 80). However, according to Stack, "There is no convincing evidence to recommend the use of bronchodilators, corticosteroids or antibiotics" (80). Ribavirin, an anti-viral agent, may help prevent ventilation in this group of patients when administered through nebulisation. Breathing an oxygen and helium mixture (helox) may relieve the burden of heavy breathing in the patient (Pruitt 64). The RSV patient should be isolated in a private room and with equipment dedicated to the infected person. To aid in the prevention of the spread of RSV, prevent people who exhibit symptoms of respiratory infection from "visiting pediatric, immuno-compromised, or cardiac patients" (Pruitt 64).
Prognosis
RSV infection rarely causes death in infants and young children who seek early treatment. In older children and adults, the symptoms are usually mild and recovery is complete. However, according to Goldenring, "There is evidence suggesting an increased incidence of asthma in children who have developed RSV bronchiolitis". The mechanism is unknown as to whether a predisposition to asthma also presented a predisposition for developing bronchiolitis as a child or if the RSV induced bronchiolitis predisposed the child for asthma (Goldenring).

Respiratory Protection

...?Introduction Respiratory protection is required in a number of different work situations where the personnel are exposed to harmful substances that may be inhaled or ingested. Such situations involve work areas where there is harmful dust, smoke, gases, sprays, fogs, mists and vapors. In case that these hazards are not protected against, there are chances that the personnel exposed to these things may suffer from lung impairment, cancer as well as other diseases. The use of respiratory protection ensures that millions of workers escape damage to their respiratory systems. (OSHA, 2011) However the kind of respiratory protection required for each situation is different and should be used accordingly to ensure maximum damage protection...

Respiratory

...?Topic: Respiratory Respiratory system proves to be one of the most essential parts of human bodies since it involved the inhale and exhaleof air thereby allowing oxygen to enter the body and carbon dioxide to exhale out of the body. Thus an understanding of the system and its functions is also necessary. This is primary because there are several factors that may affect the properties and functioning of the system. This particular study focuses on such an understanding and focuses on the structure and function of the respiratory system and the associated diseases and diagnosis as well. Introduction: In terms of physiology, the process of respiration is described as an “interchange of gases between an organism and its environment” (Davies...

Respiratory System

...Respiratory System Q1. Respiration and ventilation Ventilation describes inspiration and expiration while respiration describes how gases are exchanged between alveoli and the blood, and also between the cells and the blood. In simple terms, respiration entails all aspects of breathing. Both respiration and ventilation are crucial in an organism. However, ventilation entails constant process of taking in oxygen and taking out carbon dioxide. Respiration, on the other hand, involves the breakdown of oxygen by the body to enhance easier use by the body. Ventilation is purely physical process while respiration can be regarded as a chemical process. Ventilation takes in oxygen into the lungs and respiration supplies this oxygen into the body...

Respiratory Syncytial Virus

..., transmission, causes, disease progression, treatment, preventions and outcomes. Respiratory Syncytial virus is a genome RNA virus and belongs to the family paramyxovirs. It has fusion proteins on its surface that allow the virus to fuse the host cells forming multinucleated giant cells called syncytia. Humans are the natural hosts and it has two main serotypes which include subgroup A and subgroup B. Transmission of the virus is via respiratory droplets and also by direct contact of infected hands with nose or mouth (Levinson, 2008). The infections are commonly initiated during the winter season from October to December and end of March to May. RSV A causes more clinically significant diseases than B and is also more common.

Respiratory Syncytial Virus (RSV) infection: A comparison of nanoparticle vaccines with traditional vaccines

... research, DNA transfections of avian cells were used to generate a chimeric Newcastle disease virus (NDV) core-protein that had the respiratory syncytial virus (RSV) ecto-domains (Ko et al., 2014). Experiments also show that VLP vaccines induced specific antibodies response and cytokine CD8 T cell response (Gregory et al., 2013). This demonstrated that the nanoparticle which is developed from DNA of protein and lipids developed from avian cells induce a specific immune response. This preparation is easy to develop without utilizing the virus itself. This demonstrates the ability to develop nanoparticles vaccine using the modern nanotechnology. Recent research has further shown that infectious virus can be recovered from DNA clones of RSV...

The first Hantavirus isolation took place in 1976 and was named the Hantaan virus (Erek and Buzgan, 2009). In May 1993 a major outbreak of Hantavirus infection occurred in the southwestern part of the United States. The affected region was the "The Four Corners" area shared by four states, Arizona, Colorado, Utah, and Mexico (CDC, 2006). The virus was identified by the Center for Disease Control or CDC after thorough investigation. The Hantavirus identified in the outbreak was the Sin Nombre virus (CDC, 2006). The deer mouse or Peromyscus maniculatus was the main host of the virus (CDC, 2006). Deer mouses live in rural and semi-rural areas, especially in the barns, outbuildings, homes, and woodpiles.

How Human Papilloma Virus Causes Cancer

...How HPV causes cancer? Introduction: Most of cancer cases that exist in the world happen because of viruses. Both DNA and RNA viruses are able to cause cancer in humans. One of the DNA viruses is Human papilloma virus (HPV)(Liao, 2006), which belongs to the family of papoviruses, non-enveloped, double stranded DNA viruses (Levinson and Jawetz, 2000) figure 1. Human papillomavirus were discovered after cottontail rabbit papillomavirus (CRVP). The first investigation of HPV in human cancer was conducted in 1970s, particularly in patients with epidermodysplasia verruciformis. (Howley, 2006). HPV usually causes benign papillomas or warts in humans (Liao, 2006). These viruses can also affect humans worldwide, especially women...

It encompasses a series of the interlinked pathways that tends to function either in the absence or presence of oxygen. The aerobic metabolism usually converts a single glucose molecule into various molecules. There are also countless chemical reactions that often take place within various cells and have a responsibility for most of the organism’s actions...
