The measles virus is an enveloped virus bearing a lipid bilayer. The bilayer holds the receptor binding hemagglutinin (H) protein and the fusion (F) protein. For infection to happen, the H protein ...

The crystal structure of the hemagglutinin of both the viruses is similar, especially within the Sa antigenic site. Compared with seasonal influenza outbreaks, the overall impact of the 2009 H1N1 ...

The genome structure introduces complications, however. For example, the NS segment is small, producing a single PCR product that is less than 1000 bases, while the 2.3 to 2.5 kilobase PD2 segment ...
