direct and indirect
branch of medical science investigating health and disease conditions within a population
epidemiology
indirect or direct spread: contaminated objects
indirect
putting on PPE
Donning
taking off PPE
doffing
diseases and illnesses that cannot be spread person to person
noncommunicable disease
disease spread by physical contact between infected individual and susceptible individual
direct contact
indirect spread through contaminated soil, water, vegetation
environmental reservoir
vector-borne
How do I determine goggles or face shield?
goggles = impact risk
face shield = no impact risk
Noncommunicable disease occurs do to these two sources
genetic and environment conditions
disease spread without direct contact between persons
indirect spread
