Antigenic shift and drift of influenza virus

Maria Elizabeth Marquez-Contreras*

One way flu infections change is classified "antigenic float." These are little changes (or transformations) in the qualities of flu infections that can prompt changes in the surface proteins of the infection: HA (hemagglutinin) and NA (neuraminidase). These transformations in the infection's qualities can prompt changes in its surface proteins Hemagglutinin (HA) and Neuraminidase (NA). Known as antigens, these are perceived by the resistant framework, provoking an immunological reaction that can bring about disease and advance invulnerability later on. As the infection imitates, these progressions in antigenic float happen consistently.
