Hepatitis C Support Group
Hepatitis C is a blood-borne viral disease which can cause liver inflammation, fibrosis, cirrhosis and liver cancer. The hepatitis C virus (HCV) is spread by blood-to-blood contact with an infected person's blood. Many people with HCV infection have no symptoms and are unaware of the need to seek treatment. Hepatitis C infects an estimated 150-200 million people worldwide.

I heard on the news that we are having an outbreak here in Atlanta. I usually get the flu every year and since I've been getting vaccinated, I only get a mild cold.

How the Flu Virus Can Change: Drift and Shift
Influenza viruses can change in two different ways.
One is called antigenic drift. These are small changes in the virus that happen continually over time. Antigenic drift produces new virus strains that may not be recognized by the body's immune system. This process works as follows: a person infected with a particular flu virus strain develops antibody against that virus. As newer virus strains appear, the antibodies against the older strains no longer recognize the newer virus, and reinfection can occur.
an A/California/7/2009 (H1N1)pdm09-like virus;
an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011;
a B/Massachusetts/2/2012-like (B/Yamagata lineage) virus.
Compared to the 2012-2013 seasonal influenza vaccine, the H1N1 component is the same, the H3N2 component is the same*, and the B component is different.
This season, most seasonal influenza vaccines will have the above-listed three virus components, but some quadrivalent (four-component vaccine) will also be available. Quadrivalent vaccine this year includes the three viruses listed in the bullets above, and also a B/Brisbane/60/2008-like (B/Victoria lineage) virus.
