What virus is the cause of the common cold
picornavirus - Rhinovirus
Infection with which virus will lead to opportunistic infections of the host
HIV
What is the structure or the influenza virus
RNA Helical Enveloped Single Stranded 8 segments
How does influenza virus kill you
causing the immune system to overreact
What virus has the gaped DNA genome
Hepadena (HEP B)
What are the targets for antiviral drug intervention
Viral absorption penetrating and uncoating Viral Nucleic Acid Synthesis Binding To intact virus particle Virus release
What is Antigenic shift
When multiple flu viruses get into a single cell, and the 8 segments get mixed up which results in a flu virus that humans have no immunity against
What is antigenic drift
When a large number of mutations has occurred in the genome of a flu virus, causing it to be changed
what do antigenic shift and antigenic drift cause
antigenic shift causes a pandemic
antigenic drift causes a epidemic
What is an icosahedron
20 equilateral triangles
30 edges
12 vertices
What are the four important TLRs for viral detection, what do they detect, and what do they cause to be synthesized
TLR 3 - double stranded RNA - (IFN-B)
TLR 7&8 - Single stranded viral RNA - (IFN-a)
TLR 9 - Unmethylated CpG - (IFN-a)

- Attachement
- Penetration
- Uncoating
- early Transcription
- early translation
- genome replication
- late transcription
- late translation
- assembly
- release
What is the viral family of HEP B

What is a primary infection of Herpes like
it is the initial herpes infection, usually in children, and its symptoms are sores around the mouth (chicken pox)
What is a secondary infection of herpes
after the infection has gone into the latent stage (no symptoms) it will all the sudden come back to different areas of the body. the reemergence of the infection is the secondary infection (cold sores, mono, shingles)
Which herpes virus can be prophalactically treated with a vaccine
HSV-2
Which viruses can lead to lesions in the oral cavity
Herpes
HPV
Paramyxoviridiae (measles)
can a person with shingles (secondary herpes infection) infect another person with chicken pox (primary herpes infections)
yes
T or F, saliva is not highly infectious for HIV (Is saliva anti-HIV)
True (it is anti-HIV)
