determined. Of blood specimens submitted none has been confirmed as Western or St. Louis encephalitis to date. Western equine virus has been isolated in 10 pools of mosquitoes in Kern and Fresno Counties; and the St. Louis type in 4 pools from the same area. The Culex tarsalis index has shown a moderate rise but is considerably below that of 1952.
The incidence of poliomyelitis increased about 7 percent from that of the week ended August 8, when 1,871 cases were reported. The total for the current week is 1,997, which is 40 percent below the number reported for the same week last year. The cumulative total for the disease year” is now 12,214 as compared with 15,136 for the same period last year. The totals for corresponding parts of the calendar years are 13,728 for 1953 and 16,329 for 1952.
It now appears that the total for 1953 will be substantially below the provisional total of 57,626 reported in 1952. Because of the fact that very few States are showing consistent increases from week to week, it is probable that the peak will be reached earlier this year than last. Only Illinois, Minnesota, and California have shown a consistent increase in the number of cases reported over the past 6 weeks. Of these 3 States, only California is reporting more cases this year than last.
Thirty-nine deaths were reported for the current week as follows: New York City, 1; Ohio, 5; Indiana, 1; Illinois, 6 (1 each in Cook, DuPage, Kane, and Moultrie Counties, and 2 in Macon); Michigan, 4; Minnesota, 6; Florida, 1; Kentucky, 3 (1 each in Elliott, Martin, and Ballard Counties); Arkansas, 1; Montana, 1; Washington, 1; Oregon, 1; and California, 8 (1 each in Butte, Los Angeles, Orange, and Riverside Counties, and 4, including 1 military, in San Diego County).
Mr. F. M. Prince, San Francisco Field Station, PHS, reports two positive plague specimens that were collected July 29, and 31, 1953, from rodents trapped in San Mateo County, California, about 2 miles south of the San Francisco city limits. These specimens were as follows: A pool of 58 fleas (Hystrichopsylla dippiei, Malaraeus telchinum, Catallagia wymani, Nosopsyllus fasciatus, and Atyphloceras multidentatus) from 14 field mice (Microtus Californicus) and a pool of 7 fleas (Opisodasys nesiotus and Malaraeus telchinum) from 3 deer mice (Peromyscus maniculatus).
Dr. W. J. Murphy, Georgia Department of Public Health, gives information on 4 cases of psittacosis reported in 2 localities of the State. The symptoms, in general, were chills, fever, headache, and generalized aches and pains. Pneumonic consolidation developed later but cough, sputum, dyspnea or chest pains were not present. Blood specimens obtained from 2 patients during the first week of illness gave a negative complement fixation reaction. Specimens obtained during the third week were positive for 3 in a dilution of 1:128 and for 1 in a dilution of 1:4. All patients were in contact with parakeets about 3 weeks prior to onset of their illnesses. The virus was recovered from 2 birds out of 6 which were purchased from 2 different aviaries in the same town. Forty-one birds from these aviaries were examined and virus was recovered from 21.
Dr. W. L. Halverson, Director, California Department of Public Health, reports a case of botulism which had onset the latter part of June. At first the diagnosis was bulbar poliomyelitis and the patient was placed in a respirator. The final diagnosis clinically is botulism. Home-canned huckleberry juice was the suspected cause of infection. The can of juice implicated had been discarded but samples taken from the same canning lot were found to contain type A Botulinus. The toxin was confirmed by animal inoculation.
Dr. W. L. Halverson, reports 22 cases of malaria in military personnel, 21 of which are known to be vivax infections. Nine of 10 civilian cases are reported as vivax type. Four of the 10 are Korean veterans, 1 is reported as having had malaria in Arkansas 20 years ago, 2 are in Mexican nationals, 2 as having been infected in a teen-age girls camp last summer, and 1 clinical case in a person who had been in China up to 3 months ago. One of the Mexican nationals was described as a "wetback” who has been deported. This individual reported 5 others, who have not been found, with similar symptoms living in a camp with 150 other Mexicans.
Dr. D. E. Biswood, County Health Officer in New York State, reports an outbreak of infectious hepatitis among 114 children in an institution. The children were housed and fed in 6 different apartments but the food was prepared centrally. The infection may have been introduced by a boy who had been home and who returned the first part of April with what might have been hepatitis without icterus. The outbreak began about the middle of May in his apart ment and later spread to 2 others affecting a total of 22 children. The disease was mild and lasted 3 or 4 days. The symptoms were fever, headache, jaundice, and nausea. In some instances epigastric pain was noted. Ten cases were reported at first, which were isolated from 10 to 14 days, and no new cases occurred until June 1. At that time gamma globulin was requested because further spread seemed likely. The prophylaxis was given on June 9 and only 1 case, having onset June 10, has been reported since that time.
Dr. A. C. Hollister, California Department of Public Health, has summarized the current status of encephalitis in the State for June and July. In June, of 25 cases reported 16 were postinfectious types (chickenpox, measles, and mumps) and 9 were undetermined types which include suspect arthropod-borne cases. In July, 30 were reported of which 19 were postinfectious, and 11 un
Dr. A. A. Jenkins, Utah Department of Health, gives a more complete report on the small outbreak of typhoid fever given in this report for the week ended June 6. Six of the patients gave a history of eating a noon meal in the same cafeteria on the 6th or
13th of April or on both days. None of the persons involved met or ate there at the same time. Three were acquaintences who lived in the same town. A seventh case was reported in a wife of one of the 6 patients. She became ill 3 weeks after her husband's illness and is probably a secondary case. Blood and stool specimens were obtained from all the kitchen personnel at the cafeteria. One food handler was found to be a typhoid carrier. This person discontinued work at the cafeteria and no more cases have been reported from this source. All 7 cases have been phage typed E1. The typing of the carrier is still in progress.
candy revealed no poison and bacteriological examination of it showed no pathogens. Stool cultures of 2 patients were negative for salmonella and shigella organisms. Stool cultures of 3 members of the family, who were not ill, were positive for Salmonella newport. The family had eaten cold meat balls and spaghetti and home-canned foods. The diagnosis of 2 patients was staphylococcus food poisoning. Botulism was considered and further investigation is pending.
Because of space limitation outbreaks of gastro-enteritis are briefly outlined as follows: (1) In Massachusetts 5 persons became ill following a meal at a party of 10 guests. Salami was suspected to be the vehicle of infection; (2) Louisiana reported an outbreak which affected 25 persons among 96 who attended a benefit dinner. The meal consisted of chicken, spaghetti, and potato salad; (3) In Missouri an estimate of 30 persons became ill after eating beef sandwiches; (4) In California 263 cases of gastro-enteritis occurred in a camp following a lunch which consisted of meat sandwiches.
Dr. Andrew Hedmeg, Louisiana Department of Health, reports an outbreak of 4 cases of gastro-enteritis in a family of 9 persons. The symptoms were severe abdominal cramps, fever, headache, mild diarrhea, nausea, and vomiting. It was believed they had been poisoned by candy but 2 other members of the family ate the same kind of candy with no ill effects. Chemical analysis of the
