Middle Eastern Respiratory Syndrome Coronavirus

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

West Nile Virus has emerged in recent years throughout the temporate zones of Europe and North America. Causing a variety of conditions in its hosts, the most serious manifestation of WN virus infection is fatal encephalitis (inflammation of the brain) in humans and horses, and many birds.

The respiratory syncytial pathogen is a non-segmented negative -sense single stranded RNA virus that falls under the paramyxoviridae family. The virus is comprised of 10 genes the encode 11 proteins and is divided into two subtypes A and B, which further divide into multiple genotypes. Genetic studies have tried

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

In September of 2012, beginning in the country of Saudi Arabia, hospitals began seeing increased cases of a respiratory virus never before seen in humans. They named it Middle East Respiratory Syndrome, or MERS. MERS is a viral respiratory illness caused by the coronavirus. It was originally thought to have started there in Saudi Arabia. It was not until later that they were able to trace the origin back to Jordan starting in April of 2012. All outbreaks of MERS have been traced back to originating from the Arabian Peninsula (CDC, 2015a). Unfortunately, it is not known exactly how MERS was contracted in humans, but it is believed to have come from an animal source, probably from camels. Strains of MERS

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).

SARS is a respiratory infection caused by the coronavirus that was thought to have originated in Guangdong China but was not reported until

SARS (Severe Acute Respiratory Syndrome) is a respiratory illness caused by a coronavirus, originally reported in Asia in February 2003 and spread to over two dozen countries before being contained (Centers for Disease Control and Prevention [CDC], 2005). Once infected, individuals with SARS initially develop a high fever and other flu-like symptoms including headache, body aches and “overall feeling of discomfort” before, in most cases, progressing to pneumonia (CDC, 2005).

RSV plays a major role in respiratory infection among the childhood population, especially infants and younger children. It is the leading viral agent respiratory tract disease worldwide, causing bronchiolitis and pneumonia in infants and young children. There are about 100,000 cases and 4,500 deaths yearly of RSV infections in the United States (1). Typically, all children are infected with RSV by age 2 to 3; however, the infections can reemerge up to 5 to 6 per year. RSV was first extracted from chimpanzees that were showing upper respiratory tract disease as an agent in 1956 (1). The chimpanzees had an upper respiratory tract illness in addition to coryza, runny nose, and malaise. The humans that interacted with these

There is still a great deal of information to learn from the study of viruses and the continued exploration of the viral genome is crucial in understanding how viruses communicate, transmit from host to host and evade immune responses. The ever-change nature of the viral genome has shown us that the most dangerous viral infections of today may be undermined by newer and more effective viruses, resulting in catastrophic outcomes. Through the study of viruses, it is the hope of the scientific community to be ahead of the viral curve, preventing infections before they even

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

SARS, also known as Severe Acute Respiratory Syndrome, caused a major epidemic in 2002-2003. The virus had originated in the middle east area from a mammal group handled and bred in the first effect area. The virus had developed and was transmitted to the people handling the animals. The handlers would contract the virus and then would spread it to others around them. The disease was able to be transferred or passed on to others by means of close contact and or the air. The virus itself was not noticeable unless tested or until it had further developed. Anyone who had contracted the disease only showed flu like symptoms when first diagnosed with the virus. However, these would soon worsen and even take the lives of people. Though it only affected

SARS appears to spread by close person-to-person contact. It is thought that transmission is most readily occurred through respiratory droplets. These can be produced when an infected person coughs or sneezes. These droplets are propelled through the air and are deposited on the mucous membranes of the mouth, nose, or eyes of a person that is nearby. It is also possible that the virus can spread when a person touches a surface or object contaminated with infectious droplets and then touches their mouth, nose, or eyes. Furthermore, it is possible that SARS-CoV might be airborne spread or by other methods that are not yet known.

A number of studies have supported the theory that the virus had originally occurred in animals previous to human infections.5 The MERs-CoV virus is a type of coronavirus that has been known for infecting both birds and many species of mammals. These types of infections are commonly referred to as zoonotic diseases because the pathogens are able to be transferred from animals to humans. Zoonosis can happen with or without a vector in order to spread the infection. Although the exact origin of the MERs-CoV infections is unknown, there has been convincing research performed that has found related types of coronaviruses in bats and camels. According to the Center for Disease Control and Prevention, the coronavirus is found in multiple species and can cause respiratory illness and gastrointestinal upset.

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).
