It is estimated that about 3.4 million children worldwide suffer from respire-tory syncytial virus (RSV) related pneumonia each year. RSV is a respiratory tract infection which mainly affects infants, children and women of childbearing ages. The latest estimates indicate that RSV-related hospitalizations with RSV co-infection account for about 8.7% of all childhood admissions.
RSV is caused by a group A picornavirus which causes inflammation in the upper airways that leads to wheezing, coughing and difficulty breathing. There are no specific treatments for RSV but various medications have been found to reduce the severity of the symptoms in infected children.
A number of RSV vaccines have been developed in the last few decades, however their efficacy in clinical trials has not been satisfactory.

Genetic evolution of coronaviruses and its implications for viral pathogenicity and host range evolution.
The evolution of the coronavirus genome has been extensively studied using a meta-genomic approach that takes into account both inter- and intra-species comparative analyses of the complete coding regions (CCRs).tory syncytial virus (RSV). RSV has been associated with a range of serious, but non-life threatening, consequences including bronchiolitis, pneumonia and pulmonary surfactant deficiency. This article discusses the importance of RSV prevention and treatment in babies and young children. It also includes practical tips to help parents understand the symptoms and how to care for their infant or child at home when they become ill with RSV. For example, it provides instructions on how to keep an infant calm during an illness like RSV by resting them on their side instead of holding them upright.
The respiratory syncytial virus (RSV) is an RNA virus that infects the cells lining the chest and breathing passages. The immune system protects infants from RSV between the ages of two and six months, but they are particularly susceptible to infection after this period of protection wears off. The effects of RSV on infants vary but can be severe as a result of a weakened immune system and problems with airway passages. Symptoms include wheezing and difficulty breathing, which can sometimes lead to hospitalization or admission to intensive care if pneumonia develops. Babies may also experience chest congestion, runny nose, fever and watery eyes.
