3.2.3

Disease transmission that occurs when a susceptible host touches an infected individual or is exposed to their body fluids.

• Central Indirect Contact

• Direct Contact

• Attachment

• Replication

Disease transmission that occurs when a susceptible host inhales infected particles, touches an infected object or is bitten by an infected insect.    

• Direct Contact

• Maturation

• Attachment

• Cenral Indirect Contact

The stage where Viral proteins bind to the host cell surface

• Release

• Entry

• Attachment

• Maturation

The stage where the virus enters the host cell through endocytosis or conformational changes in the cellular membranes.

• Attachment

• Assembly

• Entry

• Release

The stage where the virus capsid degrades, releasing genomic information.

• Assembly

• Maturation

• Release

• Uncoating

Transcription or translation for RNA or DNA viral genomic information begins.

• Replication

• Assembly

• Maturation

• Release

The products of replication begin to come together.

• Attachment

• Uncoating

• Entry

• Assembly

The viral proteins and viral genome are packaged into new virions.

• Assembly

• Release

• Maturation

• Attachment

The new virions are released from the host cell through cell lysis or budding.

• Assembly

• Entry

• Release

• Attachment

Which is an example of Direct Contact

• Physical Contact between the source and reservoir

• Occurs when small particles stay in the air

• Occurs when a non living object carries an agent
