Respiratory Syncytial Virus Essay

Respiratory Syncytial Virus (RSV) causes acute respiratory tract infection in patients of all ages and is one of the most popular diseases of childhood. Respiratory syncytial virus (RSV) infection, which manifests primarily as bronchiolitis and/or viral pneumonia, is the leading cause of lower respiratory tract (LRT) infection in infants and young children. RSV is the most common cause of bronchiolitis (inflammation of the small airways in the lungs) and pneumonia in children under one year of age in the United States. During the first year of life, most infants are infected with the virus. Most RSV infected children encounter

Respiratory Synctial Virus (RSV) is an infection that is contagious that resembles the common cold a lot of times. RSV is the most common viral pathogen that causes lower respiratory tract infections in infants. RSV infection in infancy cause severe bronchiolitis and pneumonia and may incline children to the following development of asthma, the most common chronic illness of childhood. RSV is the most single related cause of pneumonia and bronchiolitis. Epidemics of the virus are seen each winter, 80% of infections typically occur during a three-month period. The virus is not typically severe during infancy but it is rare if it happens. (As, in my case I was born with the RSV virus and was hospitalized for eighteen days and was put on assisted ventilation.) In infants RSV infection can spread to the bronchial tubes and lungs. The virus can also infect adults, in where the infection can cause viral pneumonia, which is sometimes followed by a bacterial infection of the lower respiratory system.

Middle East Respiratory Syndrome (MERS) is a severe acute respiratory illness caused by the coronavirus named MERS-CoV. It is believed that the virus is found in camels and passed on to humans who are in contact or around infected animal. These camels are mainly located in Egypt, Oman, Qatar, and Saudi Arabia (WHO, 2015a). Those infected with MERS exhibit fever, cough, and shortness of breath, pneumonia, and diarrhea. Severe cases require patient to be put on mechanical ventilation or in an intensive care unit. It is also known to cause kidney failure and septic shock. The elderly, persons who are immunosuppressed, those who

Respiratory Syncytial Virus (RSV) is considered the leading cause of lower respiratory tract infections (LRTIs) in infants and young children. Each year, 4-5 million children younger than 4 years acquire an RSV infection, and more than 125,000 are hospitalized annually in the United States because of this infection. (Medscape, 2016).

According to the Centers for Disease Control and Prevention (CDC, 2013) national healthcare disparities report for 2010, influenza and pneumonia are ranked within the top ten major causes of death in the United States. The influenza viruses that will be discussed throughout this case study include the human influenza viruses: A and B. These viruses are responsible for seasonal epidemics during the fall and winter around the globe in temperate environments. Historically influenza outbreaks have had a seasonal distribution and characteristic time course although according to the CDC (2017) factors influencing the extent and severity of an outbreak are less clear. Generally, there are two or three different influenza strains typically circulating concurrently in any given

RSV comes into the airway epithelium from the apical side only and aims to destroy the ciliated epithelia cells (4). Then RSV buds and releases the virus from the apical surface (4).

More and more recently, we have been finding new “emerging” diseases that continually baffle scientists as to how they came to be. Many of these diseases have not left the public eye yet, such as HIV/AIDS, Ebola, and the yearly strains of Influenza; however, we must remain vigilant of every disease that plagues humanity – including the all but forgotten West Nile Virus.

The most common pathogen of acute viral rhinitis is rhinovirus, other causes include, adenoviruses, coronaviruses, enteroviruses, influenza and parainfluenza viruses, and respiratory syncytial virus. The most common pathogen of rhinosinusitis is S pneumoniae, H influenzae (nontypeable), M catarrhalis, and β-hemolytic streptococci. Common pathogen of viral pharyngitis includes, Epstein-Barr virus, coxsackie A group of viruses and adenovirus. The most common bacterial pharyngitis is group A streptococcal infection, other causes include Mycoplasma pneumoniae, Chlamydia pneumoniae, groups C and G streptococci, and

Bronchiolitis is defined by the textbook as, “a diffuse, inflammatory obstruction in the small airways or bronchioles occurring most commonly in children” (Heuther & McCance, 2012). It is an acute inflammatory disease of the lower respiratory tract that occurs most commonly in infants and is caused by infection with seasonal viruses such as respiratory synctial virus (RSV) (Zorc & Hall, 2010). Bronchiolitis often results from an obstruction of the small airways. It is the leading cause of infant hospitalization in the United States (Zorc & Hall 2010) and is arguably the most common significant medical illness of childhood, with at least “1 in 7 normal infants developing symptomatic bronchiolitis in his or her first year of

In the human body, there are commensal bacteria serving as part of the normal flora. Various viruses can interact with these bacteria in order promote their infectivity. Poliovirus can bind with bacterial lipopolysaccharide (LPS) for stabilization to prevent premature RNA release and improve cell attachment to host cell through the poliovirus receptor. For retroviruses, specifically MMTV (mouse mammary tumor virus), binding to LPS improve their chances of successful transmission. MMTV-bound LPS get binds to toll-like receptor 4, which is a pattern recognition receptor of LPS. This event eventually leads to the induction of interleukin-10 (IL-10), which is an immune response inhibitory cytokine. By producing IL-10, it allows MMTV to go undetected by the

Flavivirus is a group of single-stranded RNA viruses in Flaviviridae family that are causative agents of public health diseases such as Murray Valley encephalitis and West Nile fever. Since 1917, arboviral encephalitis has some sporadic occurrences in south-eastern Australia due to heavy rainfall following by widespread flooding that caused to enhance the population of water birds and mosquito vectors (Doherty, 1977). MVEV was first found and isolated from the passed away encephalitis patients in 1951 around Murray Valley. It was called ‘Australian encephalitis’ at the time, which covered WNV/KUNV and other flaviviruses infection (Anderson, 1954). However, the investigation later suggested that these viruses are causing different diseases (Doherty

The common cold is a self-limiting upper respiratory tract infection with sign and symptoms of nasal congestion, runny nose, sore throat, sneezing, and cough. It is a viral disease that does not respond to antibiotic (Zoorob, Sidani, Fremont & Kihlberg, 2012). The common culprits that cause the infections are rhinovirus, adenovirus, parainfluenza virus or coronavirus. This virus is usually spread through droplets via inhalation, aerosol, and secretion on hand or direct contact with contaminated object. This infection is highly contagious since it produces a large number of infected nasal mucosa during the first few days and can live for many days outside of a body

An invisible organism enters your body. It penetrates into your tissues and then takes over the machinery in your own cells to make more copies of itself. This tiny infiltrator works silently, producing thousands of these clones that fill up the cell and cause it to explode. The clones mercilessly continue the process of invading, taking over and destroying cells. The result might be a minor inconvenience to you as the host, or it could result in a slow or rapid death. It depends only on which variant of this unwanted infiltrator overcomes your body’s defenses. There are cures to wipe out some types of these invisible intruders, but others are so difficult to eradicate or so readily adaptable, that the world’s greatest scientists

Infectious disease is considered an ever evolving issue world-wide. A number of health officials and idealists believed that the threat of infectious disease would have been eradicated by now.1 Infectious disease remains the leading cause of death across the globe and the third leading cause of death in the United States.2 Within the scope of infectious disease, the most common cause of illness is viral respiratory tract infections, also referred to as VRTI.3 Recently, a new strain of virus related to the Severe Acute Respiratory Syndrome commonly referred to as SARS has been identified.4,5 The Middle East Respiratory Syndrome is a viral infection that affects the respiratory tract in humans and has recently been discovered in a small

MERS-CoV is a respiratory disease that was first found in Saudi Arabia in 2012. This virus can cause people to get diseases such as the common cold to a Severe Acute Respiratory Syndrome (SARS).
