RSV Proteins

Respiratory syncytial virus (RSV), also called human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a common, contagious virus that causes infections of the respiratory tract. It is a negative-sense, single-stranded RNA virus. RSV is divided into two antigenic subtypes, A and B, based on the reactivity of the F and G surface proteins to monoclonal antibodies. The subtypes tend to circulate simultaneously within local epidemics, although subtype A tends to be more prevalent. Generally, RSV subtype A (RSVA) is thought to be more virulent than RSV subtype B (RSVB), with higher viral loads and faster transmission time.
