Study Notes

Virus Classification and Characteristics

Viral Families: The provided list details various viral families, including retroviruses, herpesviruses, togaviruses, parvoviridae, papovaviruses, picornaviridae, caliciviridae, flaviviridae, hepadnavirus, rotavirus, and others.
Genetic Material: Viruses are categorized by their genetic material (DNA or RNA) and its structure (single-stranded, double-stranded, linear, etc.). This is indicated by columns in the data.
Enveloped/Non-enveloped: Some viruses have an outer envelope made of lipids, while others do not. This characteristic is listed in the data.
Capsid Morphology: The shape of the virus's protein coat (capsid) is described as icosahedral in many cases.

Viral Diseases and Associated Symptoms

Diseases: The provided data lists various human diseases associated with specific viruses, including AIDS, oral herpes, genital herpes, shingles, cytomegalovirus infections, mononucleosis, roseola, Kaposi's sarcoma, rubella, various cancers, hepatitis, gastroenteritis, paralysis, and others.
Symptoms & Characteristics: Symptoms associated with these diseases are mentioned, emphasizing specific tropisms (e.g., liver, nervous system), acute or chronic nature, prevalence rates, and potential for complications.

Diagnosis and Treatment

Diagnosis Methods: Diagnostic approaches include ELISA (enzyme-linked immunosorbent assay), Western blot, PCR (polymerase chain reaction), and viral culture. These methods are specified in the table.
Treatment Strategies: Treatments vary depending on the virus and the disease. Some involve antiviral drugs, while others involve supportive care.

Transmission and Prevention

Transmission Routes: The data indicates various transmission pathways, such as sexual contact, respiratory droplets, fecal-oral route, blood transfusions, and others.
Prevention Strategies: Vaccination programs are noted for some viral diseases.

Additional Characteristics of specific virus

Incubation & Invasion Periods: Duration of incubation period and viral invasion are documented.
MDO/Prevalence/Particularities/Viral proteins description: Includes data describing if a disease can be prevented, prevalence, unique features/characteristics of some viruses, viral proteins (e.g., GP120, GP40, P24), if acute or chronic diseases, resistance/sensitivity , etc.
