Objectives: This study examined the epidemiological and clinical characteristics and death-related factors of COVID-19 in inpatients in Zahedan, Iran. Methods: This multicenter study included all COVID-19 patients admitted to Zahedan hospitals within February to April 2020. Demographic, epidemiological, and clinical characteristics were extracted from medical records. Bivariate and multivariate logistic regression models were used to examine the risk factors associated with inpatient mortality. Results: Of 425 patients in this study, 237 and 188 were male and female, respectively. Moreover, 31 (7.29%) patients died. The patients with a severe stage of pneumonia and those with a severe/critical condition of COVID-19 were 35.8% and 35.1%, respectively. The most prevalent symptoms were cough (70.8%), shortness of breath (62.1%), fever (34.1%), bruising (28.7%), and shivering (28.5%). The most prevalent underlying diseases were hypertension (23.3%), diabetes (16.7%), cardiovascular disease (13.2%), chronic pulmonary disease (9.6%), and asthma (5.4%). Adjusted odds ratio (OR) of in-hospital mortality increased for patients with older age (OR = 3.74, 95% CI: 1.39-10.32), at least one underlying disease (OR = 1.16, 95% CI: 1.01-1.32), severe disease (OR = 30.9, 95% CI: 4.01-239.09), and critically severe disease (OR = 736.5, 95% CI: 74.75-7256.1) compared to mild/moderate disease. Conclusions: This study showed that older age, disease severity, and underlying diseases were mortality risk factors due to COVID-19 infection. This finding indicates that priorities for hospital admission must be given to patients with a higher risk of mortality due to limited facilities, especially in less privileged areas.

Methods Using sticky trap, hand collection and glass trap, 250 cockroaches were collected from 14 wards of 5 hospitals. After having their identification determined by detection key, all of them were used to isolate bacteria from cuticle and alimentary tract. Results From four identified species, Blatella germanica were the most common in all of the wards (88.8%) and next was the Periplaneta Americana (8%). 20 bacteria species isolated from cockroaches' surface and 21 from digestive organ. Escherichia coli were the most predominant bacteria isolated from external surface (26.5 %) as well as alimentary tract (30.8%). The frequency of investigated bacteria on cockroaches' body surface was not significantly different between Periplaneta Americana and Blattella germanica except for Kllebsiella oxytoca (P Conclusions Since cockroaches can carry pathogenic bacteria, so their existence in the hospitals could be a serious public health problem. It is suggested to compile programs in order to control cockroaches especially in the hospitals.

This survey was done to determine prevalence and risk factors associated with head louse (Pediculus Humanus Capitis) in Central Iran. Materials and Methods In this descriptive-analytic study, a total of 38,237 suspected cases of head lice infestation that were referred to public health centers in Qom province during 2016 were studied. Data collection was done using standard check list that was conducted and approved by the Health Ministry of the Islamic Republic of Iran and physical examination of the hairs by visual inspections of scalp and hair for the presence of adult lice, nymphs, and eggs (nits) in all of suspected cases. For data analysis, Chi-square and Multiple Logistic Regression Tests were utilized. Results A total of 11,223 (29.35%) out of 38,237 suspected cases of all ages were found to have pediculosis. According to the multivariable logistic regression analysis, a significant relationship was observed between Pediculus capitis infestation and each of these factors: educational grade, family size, family income, having previous history of P. capitis infestation, number of combing per day (P<0.05). Head lice infestation was detected in 33.45% (7,182/21,469) of females and 24.09% (4,041/16,768) of males. Conclusion High prevalence of P. capitis among people of all ages, especially in students who reside in Qom province was attributable to inadequate access to health educators, health facilities, inattention to personal health, and other related factors.
