Flu/Anbx Flashcards
(25 cards)
MC types of flu
A and B
H1/H2/H3 and N1/N2 can cause pandemic
how is flu transmitted
via inhalation of large and small aerosolized particles
refers to minor changes in HA and less often in NA that occurs frequently (usually every few years)
antigenic drift
occurs only in influenza A as a result of acquisition of new gene segments of HA and/or NA (occurs every few decades). Result: major antigenic change causing pandemics
antigenic shift
S/S flu
Abrupt onset, fever (100-1040 F), sore throat, myalagia,
who should get the flu vaccine
All persons 6 months or older
meningococcal vaccine does not cover
group B meningococcus
which vaccine an’t be given to pregnant ladies/immunosuppressed
