Retroviruses
Class of RNA viruses that can produce double stranded DNA copies of their genome and then integrate into the chromosome of the host cell using reverse transcriptase, key example being HIV
Transplacental transmisison is…
…vertical transmission
Generally longer incubation times mean…
…the infection damage is further from the primary site of infection
Respiratory viruses
Influena Coronavirus Rhinovirus Adenovirus Parainfluenza virus Respiratory syncytial virus
Influenza is what type of virus?
RNA virus
2 major types of influenza that cause infection and what type of antigenic variation do they undergo?
Antigentic drift - both influenza A and B
Antigenic shift - A only (most severe epidemics)
Influenza diagnostics
Rapid influenza test can give results in 30 min, not most accurate, otherwise must viral culture for 3-10 days
Often patients with influenza virus develop a secondary…
…bacterial pneumonia infection
Complications of influenza
- Bacterial 2ndary pneumonia infection
- Guillian Barre syndrome
- Reye’s syndrome (swelling in liver and brain, this is why we don’t give aspirin)
Influenza treatment
- Neuraminidase inhibitors, not very effective
- Adamantane antivirals, rare to use as so much resistance
