Study Notes
Reyes' Syndrome
- Linked to flu and chickenpox, and aspirin use
- Causes massive inflammation throughout the body, liver damage, and brain swelling
Viral Components
- Viruses are composed of a capsid, envelope and nucleic acid
Smallpox
- Causes severe illness with a 20% mortality rate
- Effectively eradicated due to: low cost, stable vaccine, no animal reservoirs, and detectable symptoms.
- Can only be spread via direct contact
Herpes Viruses
- HHV-1 causes cold sores, spread via contact
- HHV-2 causes genital herpes, spread through sexual contact
- Asymptomatic in children
- 95% of adults have antibodies, with 20% secreting antibodies orally
Mononucleosis
- Characterized by fatigue, sore throat, swollen lymph nodes, and an enlarged spleen in children
- 95% of adults have antibodies
- Virus replicates in resting memory B cells
- May be related to multiple sclerosis, Hodgkin's lymphoma and nasopharyngeal cancer
