"The mission of every Infectious Awareables tie is to generate interest, discussion, even excitement about serious public health issues such as this silk extra long Biohazard tie in black. Believing that humor can be a powerful educational tool, Infectious Awareables neckties take an atypical, slightly irreverent approach to some very serious subjects." Shop and take pride in knowing that a portion of the proceeds will be donated to disease research/education. BIOHAZARDS are organisms or organic substances that threaten human or animal health, including medical waste as well as microbial toxins capable of causing both disease and mortality. The Centers for Disease Control (CDC) categorizes various diseases in levels of biohazard, Level 1 (e.g. E. coli) being minimum risk, Level 4 (Ebola) being extreme risk. The universal symbol is a precautionary warning ñ so if you see it on something, you can be sure it is not a good thing!
