![Airborne or inhalation transmission
The process whereby aerosolized infectious respiratory
particles (IRPs) are inhaled and enter the respiratory tract
of a susceptible person, move through the upper and
then lower parts of the respiratory tract, and can be
deposited on the tissue at any point along the tract,
potentially even reaching the distal alveolar region.
This mode of transmission can occur when IRPs have
travelled either a short or a long distance (range) aer
emission from an infected person or aer resuspension
of deposited particles from surface.

Mechanism of
transmission
Distance from
the source of
infection &
particles sizes
The spread of an infectious
agent caused by physical
contact of a susceptible
host with people or objects.
• Direct contact
transmission involves both
a direct body-surface-to-
body-surface contact and
physical transfer of
microorganisms between
an infected or colonized
person and a susceptible
host.
• Indirect contact
transmission involves
contact of a susceptible
host with a contaminated
intermediate object (e.g.,
contaminated hands) that
carries and transfers the
microorganisms.
The spread of an infectious
agent caused by the
dissemination of droplets.
Droplets are primarily
generated from an infected
(source)person during
coughing, sneezing and
talking.
Transmission occurs when
these droplets that contain
microorganisms are
propelled (usually < 1m)
through the air and
deposited on the
conjunctivae, mouth,
nasal, throat or pharynx
mucosa of another
person.
The spread of an infectious agent caused by the
dissemination of droplet nuclei that remain infectious
when suspended in air over long distances and time.
