Monday, January 13, 2014 - Dr. Roz Eggo, Texas viruses and epidemics in general


Dr. Roz Eggo joins us on the show to explain influenza (flu) pandemics, and how immunity works.  What to the H and the N mean in the flu strains, like H1N1?  What characterizes a flu pandemic?  What is the difference between a pandemic and just a bad flu season?  How do we predict what strains will be dominant for a coming flu season?  Herd immunity helps to slow down transmission in everyone, not just those people who have been vaccinated.  Roz's research involves how hospitalizations in Texas are related to infectious disease circulation.  She uses population level models to inform the hospitalization rates.  A key factor is the contact rate of students in- and out- of school, where students get colds more easily from others.  Roz sorts out the sources of data and answers all our questions about viruses.
