The fatbreak began on January 4, when students returned from vacation. Mate- rial is being collected for a specific diagnosis. State Health Commissioner, states that an outbreak has occurred incidence of respiratory disease which began on December 29 is also reported from a federal penal institution in Oklahoma. Dr. January 3. Areas of highest incidence are in western Texas and severity. Laboratory examinations are being conducted. Dr. E. A. The number of deaths from influenza and pneumonia reported Central, 22 (12); Mountain, 6 (7); and Pacific, 10 (7). The virus was closely related to the Scandinavian strains in Center, a recently acquired strain of influenza A-prime, A/Japan 5/51, which was serologically somewhat apart from other A-prime strains which were recovered during 1951. Psittacosis In the 10-year period, 1942 to 1951 inclusive, the average annual number of cases of psittacosis reported was 23. The actual numbers varied from 1 in 1943 to 35 in 1949. During the early part of 1952, a number of cases were reported in which parakeets purchased in Florida were found to be the source of infection. Such cases were reported in Minnesota, Connecticut, and Colorado. Twenty-nine cases were found among employees of a packing plant in Texas in which turkeys were being processed. Information was received that a second epidemic occurred in the same plant later in 1952. The source of infection in each outbreak was considered to be turkeys. Information on psittacos is was received from 12 States in 1952. About 70 cases were reported by these States. In addition to parakeets and turkeys as sources of infection, canar ies, pigeons, and chickens were found to be, or were presumed to be, sources of infection in humans reported to have the disease. Dr. P. E. Marks, Pittsburgh Department of Public Health, reports that a diagnosis of psittacosis was confirmed following autopsy in a 57-year-old male. The original diagnosis was pneumonia with onset about November 10. At approximately the same time a daughter of this patient had a similar disease. A parakeet purchased by the family in West Virginia was found to be infected although not clinically ill. Dr. Morris Greenberg, New York City Department of Health, has reported that an adult male was admitted to a hospital in New York City late in November with pulmonary finding suggestive of psittacosis. Laboratory confirmation of the diagnosis was obtained. The patient had recently purchased 2 parakeets from a store which had obtained a large supply from California. Blood obtained from the 2 parakeets when tested by the complement fixation test was found to be anti-complimentary. Table 1. COMPARATIVE DATA FOR CASES OF SPECIFIED NOTIFIABLE DBEASES: UNITED STATES (Numbers after diseases are category numbers of the Sixth Revision of the International Lists, 1948) NOTE. -One case of smallpox reported by Indiana for week ended January 3, changed to chickenpoz. For the purposes of weekly comparison over a period of years, the first week of the year is taken to be that week which has 4 or more days of the new year. According to this rule, the week ended January 3, 1953, was counted as the 53rd week of 1952, and it was compared with the first week of 1952. At the beginning of 1953, the first week of 1952 was again used for comparison, this time with the first week of 1953. SOURCE AND NATURE OF DATA These provisional data are based on reports from State and territorial health departments to the Public Health Service. They give the total number of cases of certain communicable diseases reported during the week usually ended the preceding Saturday. When the diseases which rarely occur (cholera, dengue, plague, typhus fever-epidemic, and yellow fever) are reported, they will be noted under the table above.
