With a partner, discuss: How do germs spread?
Ways Pathogens Spread Direct contact Droplets (airborne) Contaminated surfaces Contaminated food or water Animals/insects
Properties of a Virus How easily it spreads Durability Fast or slow? Durability How long can it live outside the body? How quickly it kills How fast does it attack cells? How much it mutates How frequently does it change?
So, worst possible type… Spreads easily Very durable Kills slowly Constantly mutates
