  • Description:
    "For the past three weeks, mortality from influenza and pneumonia in 108 cities has been rising. This indicates a possible increase in pneumonia cases and is in sharp contrast with the general downward trend between November 29 and December 28 as the epidemic waned. The precise cause of this elevated mortality is not certain, Status reports, industrial absenteeism, the National Health Survey, and numerous investigations fail to reveal any large outbreaks. However, there is evidence of continuing small outbreaks. Asian influenza bas been isolated from several outbreak, and there has been no evidence of other strains or types of influenza. Although the recent rise in mortality is clearly higher than the season expectancy, part of it, may be explained by delayed reporting of deaths over the holidays. Health officials are urged to be alert to the possibility of sharp outbreaks of Asian influenza in areas where immunity is not high. Periodic laboratory confirmations will help establish the etiology of these outbreaks Total Asian strain vaccine released between December 11 and January 8 was 592,400 ml polyvalent." - p. [2]
