Attack rate-patient number plot for analysis of food poisonings caused by microbes and plant or animal toxins.

Attack rate-patient number plot for analysis of food poisonings caused by microbes and plant or animal toxins. Jpn J Infect Dis. 2019 Apr 26;: Authors: Yoshikura H Abstract The number of eaters and that of patients per outbreak followed lognormal distribution in food poisonings caused by microbes while it followed scale-free distribution in food poisoning caused by plant or animal toxins. Attack rates of the individual outbreaks were distributed continuously and almost linearly from>0 to 1 for all the food poisonings, i.e., they could not be represented by median and standard deviation. For monitoring of the number of patients and the attack rate in individual outbreaks simultaneously, the number of patients was plotted in the x-axis in the logarithmic scale against the attack rate in the y-axis in the normal scale. There emerged plots characterized by repeating arcs assuming shape of a butterfly with extended wings viewed from above, which was called "backbone configuration". The butterfly-shaped plot patterns were generally stable over time, but variable depending on pathogens, implicated facilities and their combinations. The backbone configuration was reproduced by assuming that the number of patients per outbreak was distributed continuously from 1 to the number of eaters per outbreak.

Abstract In Japan, from 2000 to 2018, for Vibrio parahaemolyticus and Salmonella food poisonings, the annual number of the outbreaks and that of the patients decreased exponentially though the size of the individual outbreaks (the number of patients per outbreak) tended to become larger. For food poisonings caused by Campylobacter, the annual number of the outbreaks increased exponentially while the outbreak size became smaller and the annual number of the patients remained almost unchanged. For food poisoning caused by norovirus, both the number of the outbreaks and that of the patients remained high throughout. ...

Yesterday, I revealed that the Tennessee Department of Healthreported its first death from vaping-associated respiratory illness as follows: "The Tennessee Department of Health has reported one death in a patient with serious respiratory disease associated with use of electronic cigarettes or other vaping devices. This is the first such death reported in Tennessee. "As it turns out, it appears that this death was not caused by electronic cigarettes, but byTHC vape carts.I suggested that the health department's reporting of the death as being associated with the use of " electronic cigarettes or other vaping ...

Sadly, Tennessee recently experienced itsfirst death from vaping-associated respiratory illness.Here's how the Tennessee Department of Healthreported it:" The Tennessee Department of Health has reported one death in a patient with serious respiratory disease associated with use of electronic cigarettes or other vaping devices. This is the first such death reported in Tennessee. "So which one was it? Was it the use of " electronic cigarettes " or was it the use of " other vaping devices. " If the Tennessee Department of Health truly wants to prevent further cases of this illness, it is incumben...

Last Thursday, CDC finally revised itswarning to the public about the vaping-associated respiratory disease outbreak to state clearly that vaping THC-containing products is playing a major role in the outbreak. It stated that:" The latest national and state findings suggest products containing THC, particularly those obtained off the street or from other informal sources (e.g. friends, family members, illicit dealers), are linked to most of the cases and play a major role in the outbreak. Therefore, CDC recommends that you should not use e-cigarette, or vaping, products that contain THC."In addition, CDC finallyr...

All 13 S. aureus isolates formed biofilm on polystyrene; and 84.6% (11/13) carried icaA and icaB genes, 69.2% (9/13) the icaD gene, and 61.5% (8/13) the icaC gene. A...

(CNN) — When multidrug-resistant pathogens kept reappearing on the skin of premature babies in a German hospital’s neonatal intensive care unit, investigators were confused. Tests for contamination in the incubators, as well as among healthcare workers who came into contact with the preemies, were all coming up negative, according to a report on the case published Friday by the American Society for Microbiology. But tests showed the babies were continually being reinfected with Klebsiella oxytoca, a bacteria notorious for hospital-acquired infections such as pneumonia, urinary tract infection, soft tissue infec...
