Epidemiological patterns of animal bites in Abadeh district of central Iran from 2012 to 2018: A cross-sectional study

Objectives:To investigate the epidemiology of animal bites and associated factors in Abadeh district(central Iran)from 2012 to 2018.Methods:In this cross-sectional study,1407 individuals with animal bites who were referred to the Abadeh Rabies Treatment Center were investigated by using the census method from 2012 to 2018.The variables included the victim's demographic information(age,gender,occupation),the type of biting animals(dog,cat,and other animals),the domesticated and wild animals,the time of biting based on year and month,the residence location(urban or rural),the treatment status,and the anatomical location of the wounds.Results:The annual incidence rate of animal bites was 189.62 per 100000 population.Totally 83.4%of the victims were male.The average age was(33.66±18.97)years and individuals in the age range of 36-50 years were greater at risk.Most of the animal bites were from dogs(77.8%).About two thirds(62.1%)of the bites were from household animals.A total of 57.1%of individuals lived in urban areas.Most victims were engaged in farming and animal husbandry.The highest prevalence of animal bites(37.4%)happened in the summer.None of the patients had any clinical signs of rabies.Conclusions:To reduce the incidence of animal bites,high-risk groups including farmers and ranchers should be educated about bite prevention,and it should be ensured that they are managed correctly.

Causes of delay in offering rabies post-exposure prophylaxis services in Abadeh district of Iran

Objective:To identify the reasons for delayed reception of post-exposure prophylaxis(PEP).Methods:In this cross-sectional study,a total of 1407 individuals with animal bites who were referred to the Abadeh Rabies Treatment Center were investigated using the census method from January 2012 to December 2018.The patients were divided into two groups based on their delay times to referral and receive PEP:timely referral(less than 48 h after the bite)and delayed referral(equal to or longer than 48 h after the bite).Frequency,Chi-square,and logistic regression tests were used.Results:.The average delay time was(16.33±11.37)h.Low level of education(OR:3.87;95%CI:1.19-12.54;P=0.02),active economic age(21-35 and 36-50 years-old,OR:12.81;95%CI:3.16-51.97;P<0.001 and OR:3.83,95%CI:3.83-58.61;P<0.001 respectively),occupation(OR:9.16;95%CI:1.89-44.29;P=0.006),long distance from the rabies treatment center(OR:3.41;95%CI:2.03-5.72;P<0.001),bites by household and domestic animals(OR:12.22;95%CI:2.29-65.18,P=0.003),superficial injuries(OR:4.51;95%CI:1.38-14.73;P=0.01),and residence in rural area(OR:12.74;95%CI:6.58-24.66;P<0.001)had significant correlations with delayed referral of victims.Conclusions:To reduce the delay time,the high-risk groups should be informed about the importance of timely referral via educational measures.Furthermore,rabies treatment services should be rendered at the nearest possible center.

A Review on Fossil Findings of Central Iran’s Permo-Triassic Deposits

In this research, a review was done on Permo-Triassic deposits in Central Iran including Abadeh, Hambast, and Elika formations. Following an overview about the circumstances of Central Iran Basin during Permotriassic time interval, the respective formations are introduced, and then, history of paleontology studies on these deposits will be depicted. Through analysis and comparison of previous studies, the following ages were estimated for the aforementioned formations: Early Dzhulfian for Abadeh Formation, Late Dzhulfian-Dorashamian for Hambast Formation, and Early Triassic (Scythian) for Elika Formation. Also, Permotriassic boundary in Central Iran is continuous, bearing the proposed sedimentation and fossil content. It is noteworthy that due to volcanic events at the boundary of these deposits in Central Iran, one might infer that occurrence of the aforementioned activities has been among the major causes of the respective extinction.
