    Flu Virus Change

    Influenza viruses are constantly changing. This is why they emphasize getting your yearly flu shot. An interesting feature of the influenza virion is its tendency to “drift and shift” ("How the Flu Virus Can Change: “Drift” and “Shift”." Centers for Disease Control and Prevention.). Pathologists coined this phrase when they discovered an antigenic drift in the DNA of an influenza strain. These changes are usually not big enough to affect our immune system’s ability to identify a certain strain. Over time however, these genetic drifts can accumulate and create enough of a difference in the genetic makeup to allow the virion to infiltrate the human body without being recognized. Shifting is the less common of the two, but is more aggressive. It occurs when new Hemagglutinin and Neuraminidase proteins emerge, completely changing the subtype of the virus. The change happens so quickly that…

In rare instances, airborne virus may spread farther, possibly through the ventilation system in a building, infecting people in other rooms or on other floors. Smallpox can also spread through contact with contaminated clothing and bedding, although the risk of infection from these sources is slight.…
