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 ▫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
