What Your Blood Type Says About You

Blood Can Affect Your Chances Of Getting The Stomach Flu

Norovirus, better known as the stomach flu, infects 200 million people every year. Surprisingly, your blood type might influence your chances of getting it. According to Science Times, the norovirus needs to attach to H1, a type of blood antigen. If your blood doesn’t produce the H1-antigen, you may have some immunity to the stomach flu.

AB blood types tend to be more susceptible to norovirus than O blood types. However, this can vary among individuals. The norovirus consistently changes, and immunity only lasts for around six months. Even if you are less susceptible, you could still get the stomach flu once in a blue moon.
