| laboratory-based surveillance of influenza virus in the united states during the winter of 1977-1978. i. periods of prevalence of h1n1 and h3n2 influenza a strains, their relative rates of isolation in different age groups, and detection of antigenic variants. | influenza a (h3n2) viruses were isolated from outbreaks and epidemics of disease during the period december 1977 to march 1978. for the last two months of this period, h1n1 strains of influenza a were also responsible for epidemics. in some regions (e.g., hawaii) co-circulation of h1n1 and h3n2 strains occurred, whereas in other regions (e.g., wisconsin) isolation of h3n2 strains had almost ceased prior to isolation of h1n1 strains. few influenza b isolates were reported. analysis of the ages of ... | 1979 | 507036 |
| prevention and control of influenza. recommendations of the advisory committee on immunization practices (acip), 2007. | this report updates the 2006 recommendations by cdc's advisory committee on immunization practices (acip) regarding the use of influenza vaccine and antiviral agents (cdc. prevention and control of influenza: recommendations of the advisory committee on immunization practices [acip]. mmwr 2006;55[no. rr-10]). the groups of persons for whom vaccination is recommended and the antiviral medications recommended for chemoprophylaxis or treatment (oseltamivir or zanamivir) have not changed. estimated ... | 2007 | 17625497 |
| development of a rapid automated influenza a, influenza b, and respiratory syncytial virus a/b multiplex real-time rt-pcr assay and its use during the 2009 h1n1 swine-origin influenza virus epidemic in milwaukee, wisconsin. | rapid, semiautomated, and fully automated multiplex real-time rt-pcr assays were developed and validated for the detection of influenza (flu) a, flu b, and respiratory syncytial virus (rsv) from nasopharyngeal specimens. the assays can detect human h1n1, h3n2, and swine-origin (s-oiv) h1n1 flu a viruses and were effectively used to distinguish flu a infections (of all subtypes) from flu b and rsv infections during the current s-oiv outbreak in milwaukee, wi. the analytical limits of detection we ... | 2010 | 19959800 |
