    • Description:
      "There is no indication of an upsurge of influenza on a nationwide basis, and very few states report new outbreaks. Although there are occasional reports of re current outbreaks in previously affected populations, these are not being reported with significant frequency. Only 14 of the 36 industrial areas showed elevated absenteeism through the last week in December, and, excess mortality y from influenza and pneumonia shows only minor fluctuations in a continued downward trend. Unless a second epidemic wave develops, the Influenza Surveillance Report will be published at two-week intervals until further notice. A total of 54,442,984 ml. of Asian strain influenza vaccine was released through December 18. No recent releases have been reported. There is additional evidence that encephalitis may occasionally develop following influenza. Complete proof of cause and effect is difficult to obtain, but several case reports have established the diagnosis of Asian strain influenza in persons with acute encephalitis." - p. [2]
