Cholera outbreak at a city hotel in Kenya, 2017: a retrospective cohort study

Introduction: The Ministry of Health, Kenya (MOH) investigated a report on acute watery diarrhea (AWD) cases at a city hotel to confirm the cause, characterize, and identify associated factors. Methods: A suspected case of cholera was defined as AWD in any person aged >2 years at the hotel from August 31, 2017, to September 6, 2017. We took rectal swabs for laboratory confirmation and summarized the AWD data by person, place, and time. We defined a cohort of hotel staff with those who ate dinner on August 31, 2017, considered exposed and conducted a retrospective cohort study. We calculated attack rates (AR) and risk ratios (RR) with 95% confidence interval. Variables with p<0.1 at bivariate analysis were entered into a multivariate model and those with p<0.05 in the final model considered independently associated with the AWD. Results: Vibrio cholera was isolated from seven (10.1%) out of 69 samples. Line listed 139 cases with a median age of 32 years (Range: 20–58 years) included 127 (91.4%) male and 127 (91.4%) guests. Index case was reported on August 31, 2017, cases peaked at 95 cases on September 3, 2017, and declined to three on September 6, 2017. A total of 30 (81.1%) of 37 hotel staff were exposed with 17 (56.7%) cases. Food specific ARs were: steamed spinach 78.6% and pineapples 26.3%. Spinach (RR: 3.0 (95%CI: 1.76-72.97)) was a risk factor while pineapples (RR: 0.4 (95%CI: 0.01-0.58)) was protective. Conclusion: This was a point source cholera outbreak likely due to eating contaminated spinach

Investigation of a typhoid fever epidemic in Moyale Sub-County, Kenya, 2014\u20132015

Aim: Typhoid fever is a vaccine-preventable bacterial disease that causes significant morbidity and mortality throughout Africa. This paper describes an upsurge of typhoid fever cases in Moyale Sub-County (MSC), Kenya, 2014\u20132015. Methods: We conducted active hospital and health facility surveillance and laboratory and antimicrobial sensitivity testing for all patients presenting with headache, fever, stomach pains, diarrhea, or constipation at five MSC health facilities between December 2014 and January 2015. We also conducted direct observation of the residential areas of the suspected cases to assess potential environmental exposures and transmission mechanisms. Demographic, clinical, and laboratory data were entered into, and descriptive statistics were calculated with, MS Excel. Results: A total of 317 patients were included in the study, with mean age 24 \ub1 8.1 years, and 51% female. Of the 317 suspect cases, 155 (49%) were positive by Widal antigen reaction test. A total of 188 (59%) specimens were subjected to culture and sensitivity testing, with 71 (38%) culture positive and 54 (76%), 43 (60%), and 33 (46%) sensitive to ceftriaxone, cefuroxime, and ciprofloxacin, respectively. Environmental assessments through direct observations showed that commercial and residential areas had limited (1) clean water sources, (2) latrines, and (3) hygiene stations for street food hawkers and their customers. Conclusions: Typhoid fever is endemic in MSC and causes significant disease across age and sex groups. The local health department should develop policies to (1) assure community access to potable water and hygiene stations and (2) vaccinate specific occupations, such as food and drink handlers, against typhoid

Effect of yoga in medical students to reduce the level of depression, anxiety, and stress: pilot study (Goodbye Stress with Yoga GSY)

Abstract Introduction Globally medical students reported high level of stress sensitivity, stress intensity and depression or anxiety. Yoga is proven to be a one of the most effective anxiolytic tools. The current study specifically designed to investigate the effect of yoga intervention on the level of stress, depression, and anxiety of medical student at the University of Pécs. Methods Twenty-eight medical students from the University of Pécs, with an average age of 23.54 ± 4.36 years and a BMI of 22.42 ± 3.42 kg/m2, participated in a 10-week yoga intervention. In the current study, the DASS-21 was employed to gather information on stress, depression, and anxiety, while self-reported health and quality of life were assessed using the WHOQOL-BREF Questionnaire. The Shapiro-Wilk test was employed to examine the distribution of the data. The choice between the paired sampled T-test and the Wilcoxon signed test was determined based on the distribution of the data. Results The intervention group exhibited a mean and standard deviation of depression pre- and post-yoga 10.14 ± 10.60 and 7.21 ± 8.56, similarly the values for anxiety were 8.57 ± 10.09 and 5.51 ± 7.42, and for stress values were 12.79 ± 10.73 and 9.64 ± 9.71 respectively. Notably, this outcome attribute to a significant in decreased depression (p = 0.019), anxiety (p = 0.049) among the participants. Conclusions Introduction of Yoga Intervention significantly decreased in levels of depression and anxiety. By this current study we were able to confirm the necessity of Yoga Intervention with our primary survey
