Genetic core surrounded by protective cell wall coating. Pure Parasites
|
Virus
|
|
|
How does a virus's genetic material become incorporated into host's DNA.
|

|
|
May infect cell, but not self replicate. Until "proper conditions" arise, they cause no disease. Hose inhibits viral activity.

What is common in adults?
|
Shingles which are semi-outbreaks of the Herpes Zoster virus.
|
|
|
What are the manifestations of the mouth with Chickenm Pox?
|
Buccal Mucosa with raised red poxes.
|
|
|
What is the vaccine for Chicken Pox?
|
Varivax is used in healthy children becaue it is a live attenuated virus.
