Most influenza reported this week was in the Southeastern United States; and although sporadic outbreaks continue to occur in the Midwest and Northeast, the incidence of influenza general appears to be declining in these areas. No new major urban areas have been involved, and the outbreaks in Texas and California continue to wane. An increased amount of' febrile respiratory disease, or discrete outbreaks of clinical influenza have been reported in .a total of 41 states including the District of Columbia. Type A2 influenza virus has been isolated in a total of 26 states, including the District of Columbia; serologic confirmation of influenza A infection has been reported from four additional states. Type B influenza virus has been isolated in two states. . Mortality due to influenza and pneumonia reported from 108 cities for the week ending February 6th continued to rise, and for the fifth successive week exceeded the 'epidemic threshold'. Although this increase is noted in many regions, an abrupt decrease is noted in the Pacific region, particularly in Loa Angeles." - p. 2I. Summary of information-- II.
