CASE FATALITY RATE (Probability of dying if you get it) Probability BOTTOM LINE: 1) H5N1 is hard to get. 2) If you get it, odds of dying are 50:50.
Slide 21-

What is the risk of my getting H5N1? It’s all relative Handling live sick birds with known H5N1 Handling live sick birds Necropsying dead bird Swabbing live bird w. gloves Picking up dead bird w. gloves Sitting in this workshop H5N1 has not been found in North or South America
