    "Since publication aof the last Influenza Surveillance Report (No. 78, February 19, 1964), outbreaks first observed in northwestern Washington during late January have spread widely,involving communities throughout the states of Waashington and Oregon. Serologic studies have indicated influenza A2 virus as the etiologic agent in this epidemic. The state of Califoruia, while not experiencing extensive, community-wide outbreaks as were seen in Washington and Oregon, has nevertheless had fairly wide dissemination of influenza A2 virus among its residents -- as evidenced by changes in the following surveillance indices: 1) reports of respiratory illness, 2) school absenteeism, 3) weekly total of serologically confirmed A2 influenza cases, 4) pneumonia-influenza mortality, and 5) the occurrence of two 1nstitutional outbreaks of laboratory confirmed A2 in widely separated parts of the state. The recent influenza B epidemic in Japan (see Influenza Surveillance Report No. 78) which began in mid-January on the island of Kyushu, later spread to theĀ·main island of Honshu, and affected the Tokyo area in mid-February. Another influenza B epidemic was observed in the city of Singapore, Maylasia, during January. Outbreaks of influenza-like disease were observed in several parts of Europe during the months of February and March -- most of them attributable to Type A2 virus. The affected areas included: Czechoslovakia, Greece, the United Kingdom, and Yugoslavia. A report on the recent influenza. A2 epidemic in Taiwan is included 1n this issue. A discussion of antigenic relationships of recently isolated influenza viruses is given in the laboratory section of this issue." - p. [1]
