Acute respiratory infections are frequently brought on by RSV (Respiratory syncytial virus). RSV has the ability to take advantage of host immunity and trigger a significant inflammatory response that damages the lungs and spreads the virus. A and B are the two main antigenic subgroups of the one RSV serotype.
RSV is a non-segmented, negative-sense, single-stranded enveloped RNA virus that is a member of the Pneumovirinae subfamily of the Paramyxoviridae family and the Pneumovirus genus. Since two overlapping open reading frames in the M2 mRNA result in two different matrix proteins, M2-1 and M2-2, its 10 genes encode 11 proteins. The G glycoprotein, the F glycoprotein, and the SH protein are the three proteins that make up the viral envelope. The RSV virus has two non-structural proteins (NS1 and NS2) in addition to the large (L) protein, nucleocapsid (N), phosphoprotein (P), matrix (M), and M2-1.
