Background and Objectives: The aim of this study was to determine the prevalence of Salmonella at broiler breeder farms of Iran and investigate the factors underlying salmonellosis in these farms. This is a cross-sectional investigation conducted in 23 provinces of Iran. Materials and Methods: Fecal samples were collected from 139 broiler breeder farms in the country and standard bacteriological tests were carried out on the samples for the isolation of Salmonella. The serological tests were then applied for the samples that were positive in the bacteriological test. The information on the sampled farms extracted from the Iran GIS-VET Monitoring and Surveillance System was used for the analysis of the risk factors. Results: A total of 11 farms out of the 139 sampled farms were infected with Salmonella with the largest number of infected cases related to Tehran and Fars Provinces. Conclusion: The statistical analysis results showed that flocks with older ages and farms with larger number of houses are at greater risk of Salmonella infection.

Objective. To evaluate the operative capacity of nine serological rapid tests to detect the IgM/IgG antibodies response in serum from patients with SARS-CoV-2 in different clinical stages. Methods. A cross-sectional study of serological rapid tests was designed to compare the performance of the evaluated immunochromatographic tests for the diagnosis of SARS-CoV-2. A total of 293 samples was used, including negatives, asymptomatic, and symptomatic serum samples. Results. The sensitivity of the evaluated tests was low and moderate in the groups of asymptomatic serum samples and the group of serums coming from patients with less than 11 days since the onset of the symptoms. The specificity for the anti-SARS-CoV-2 antibodies tests ranged between 86.5%-99% for IgM and 86.5%-99.5% for IgG. The sensitivity and the likelihood ratio were different according to the study groups. The usefulness of these tests is restricted to symptomatic patients and their sensitivity is greater than 85% after 11 days from the appearance of symptoms. Conclusions. Serological tests are not an adequate strategy for the identification of asymptomatic and pre-symptomatic patients. Serological rapid tests for the detection of specific anti-SARS-CoV-2 antibodies can be used as a diagnostic aid, but diagnosis must be confirmed by RT-PCR. Rapid tests should be reserved for patients with symptoms lasting more than 11 days.

Abstract Background Disability is not just a factor of an individual’s physical condition; it develops through human interactions and reflects the social fabric of communities. Despite the fact that it directly affects 15% of Ethiopians, understanding and policy-relevant studies on disability and the conditions of persons with disabilities are lacking. The Dabat Demographic and Health Surveillance System part of the response to fill this gap. With significant drawbacks in the Surveillance System, this study aimed at assessing the prevalence, types and major causes of disability in Dabat district.Method A community-based cross-sectional study design was employed and covered 17,000 households residing in 13 Kebeles of Dabat district. The district is where DHSS collects health data semi-annually; but this study was designed and executed separately in 2018 utilizing robust tools (World Health Organization’s Disability Assessment Schedule (WHODAS 2.0) used to collect comprehensive data on disability in the district. The data was organized and presented using frequencies and percentages in table and figures. Relevant variables were used to construct a logit model that predicts the likelihood of disability whereby P-value < 0.05 was considered as statistically significant.Results This study found that the overall prevalence of disability in Dabat district was 2.14% [95% CI: 2.03, 2.24]. About 8.3% of households reported at least one member with disability. Visual impairment was the most commonly reported impairment d51%) while 8.19% had multiple impairments. Eighty-three percent of immediate the causes of disability were modifiable – specifically, illness (36.93%), injury (17.81%), and congenital (10.86%). The aged [AOR=1.0; 95% CI: 1.03, 1.04], those unable to read or write illiterate [AOR=1.57; 1.15,2.14], the unmarried/single [AOR=1.39; 95% CI: 185,2.47] and the separated [AOR=2.78; 95% CI: 4.14,6.19] were more likely to risk disability in the population.Conclusion This study reported an increased likelihood of impairment among those with advanced ages. The proportion of households with PwDs was also high. While most disabilities were visual, there were significant numbers with mobility impairments and hard of hearing. Most school-age PwDs did not complete secondary education, while employment was significantly limited. The findings indicated that most causes of disability were reversible.

Objective. This study aimed to identify the co-circulation patterns of three viruses (dengue, Zika, and ­chikungunya) in Colombia from 2008 to 2018 by using notification reports provided to the national surveillance system. Methods. This cross-sectional study was conducted through a review of data for 2008 through 2018 from Colombia’s Public Health Surveillance System (SIVIGILA). Results. In 2015, when chikungunya was first detected, it had a higher incidence (1 359.0 cases per 100 000 persons) than did the two other diseases. In 2016, when the circulation of Zika virus was first found, the incidence was 296.4 cases per 100 000 persons; that incidence declined dramatically in the next two years. Between 2015 and 2018, there was a substantial decrease in the frequency of dengue circulation, with it going from 334.1 cases per 100 000 persons in 2015 to 90.7 cases per 100 000 in 2017 and 173.1 cases per 100 000 in 2018. Conclusions. The decrease in the number of dengue cases after co-circulation of the three viruses could indicate possible cross-protection. This finding should be further analyzed.
