1

responsible for summer "cold and flu" resp infections and undifferentiated fevers

enteroviruses

1

___ complications of parainfluenza virus infections common in young,

may progess to ___

lower respiratory conplications

 

Croup

2

basic clinical features influenza

self-limited 3-7 days

secondary bacterial infections cause of death:

strep pneumo

staph a.

haemophilus influenzae

2

subacure scleorising panencephalits in measels infection

CNS - personality

behavior

memory changes

myclonic jerks

spasticity

blindness

3

(drugs)inhibit uncoating by blocking M2 proteins

 amantadine

rimantidine

4

temperature sensitivity rhinovirus

grows better at 33 than 37

4

pharyngocojunctival fever in adenovirus infection 

red eyes

sore throat

febrile

5

vaccine adenovirus

not for public (type 4 and 7 in works)

5

virus morphology picorna

+RNA non-enveloped

7

pathogenesis influenza

infects ciliated epithial cells

replication destroys resp epithelium

cytotoxic T cell - mediated damage

(viremia does NOT play a major role)

7

vaccine respiratory syncytial virus

natural infection does not prevent re-infection

re-infection especially risky in elderly

7

emerging resp viruses isolated to bats > pigs > humans in australia and Asia

hendra virus 

nipah virus

9

dates and transmission H5N1

2003-Junly 2014

does not transmit easily among people

household poultry or contaminated environment

10

adenovirus disease sequale

acute resp disease

pneumonia

pharyngoconjunctival fever

conjunctivitis

GI

hemorrhagic cystitis (bladder inflam)

11

treatment for respiratory syncytial virus 

healthy infant

premature/immunocompromised infant

premature infants

healthy - supportive O2, fluids, nebulized cold steam

premature or immunocomp: aerosolized ribavirin

premature infants: passive immunisation with anti-RSV Ig and humanized monoclonal abx

11

vaccines metapneumovirus

none (or therapies)

12

virus morphology orthomyxo and paramyxo viruses

-RNA,

enveloped

13

influenza A, B C, virus morphology and family

orthomyxoviridae 

segmented -RNA

enveloped

14

intense rash

vesicles, petechiae, prupura, or urticaria

15

16

antibodies against future influenza infections are specific for

epitopes on hemagglutinin

neuraminidase proteins

17

most common cause of death in children with measles

pneumonia

19

severe pneumonia and renal failure

still birth

nosocomial infections possible

19

post measles encepahlitis

headache

confusion

vomitng

coma after rashi disapates

20

metapneumovirus vs RSV

RSV milder, severe disease only in infants, elderly, immunocompromised

+RNA

enveloped

25

vaccine Coronavirus SARS

none
