Essays on Respiratory Syncytial Virus

Respiratory syncytial infection is an acute viral disease characterized by phenomena of intoxication and moderate lesion predominantly lower divisions Respiratory with the frequent development of bronchitis, bronchiolitis and pneumonia. A characteristic feature of this virus is its ability to determine syncytium formation or cells in tissue culture. Replicates in tissue culture HeLa, HEp-2 and human embryonic kidney. In the external environment is unstable at a temperature of 55 ° C is inactivated for 5 min.

A study of the pathogenesis of this disease is difficult. The clinical course of the disease, both natural and experimental infection among adults, does not ...

Introduction

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory tract infections (LRTIs) in infants and young children. The infection is also seen in adults and old individuals, but infants and children are more commonly affected (Krilov, 2011). Infection with RSV accounts for more than 100,000 hospitalizations every year in the US. In US, RSV is a ubiquitous pathogen infecting virtually all children at least once by the time they are three year old. Globally, RSV is associated with 160,000 to 600,000 deaths per year in children alone (Howard, 2000).

Introduction

Bronchiolitis is an infection in the lower tract of the respiratory system common amongst children. “The major cause of the infection is RSV (Respiratory Syncytial Virus) accounting for over 90% of infections in Australian children and infants” (Lenney 2009, p. 36). Globally, it is a leading cause of infant hospitalization being associated with increasing morbidity rates and costs in recent decades. For instance, it was reported that 21% of infants in North America developed the disease in the first year of their life, with an annual cost of $390 million annually (Checchia 2008). In the UK, the infant death rate ...
