Salmonella surveillance report ; no. 36, APRIL 30, 1965
Details:
  • Description:
    For the Month of March, 1965 This report marks the 36th month of salmonella surveillance in the United States and presents data concerning 1,515 human isolations of salmonellae during March, for an average of 303 recoveries per week. This represented an increase of 3 per week over February and a decrease from Majrch 1964 of 17. The first quarter of 1965 demonstrated 71 (1.6 per cent) fewer reported human recoveries than the same period last year. The difference can probably be accounted for by the Salmonella derby outbreak which resulted in 804 recoveries during the first quarter of 1964 as opposed to 175 for the same period this year. Salmonella derby accounted for an average of 62 recoveries per week during January, February, and March last year, 49 more than 1965. An editorial summarizing the _S. derby problem to date appears under Special Reports in this issue. There were 524 nonhuman isolations of salmonellae reported during March, representing an increase of 117 over February. In contrast to reported human recoveries, nonhuman recoveries during the first quarter this year accounted for more than the same period last year. This year, an average of 456 recoveries per month was reported, 78 (20.6 per cent) more than the first quarter of 1964.
