Nipah Virus (NiV) is a highly fatal emerging zoonotic virus and potential threat to global health security. Here we describe the characteristics of NiV outbreak that occurred in Kerala, India, during May–June 2018. We used real-time reverse transcription polymerase chain reaction analysis throat swab, blood, urine, cerebrospinal fluid specimens detect NiV. Further, viral genome was sequenced subjected phylogenetic analysis. conducted an epidemiologic investigation elucidate dynamics...
Nipah virus (NiV) is 1 of 10 potential causes imminent public health emergencies international concern. We investigated the NiV outbreak that occurred in May 2018 Kerala, India. Here we describe longitudinal characteristics cell-mediated and humoral immune responses to infection during acute convalescent phases 2 human survivors.Serial blood samples were obtained from only survivors Kerala. used flow cytometry determine absolute T-lymphocyte B-lymphocyte counts phenotypes both T B cells....
COVID-19 transmission was significant among Healthcare workers worldwide. In March 2020, Qatar started reporting numbers of positive cases in Primary Health Care Corporation (PHCC). The study estimates the burden aforementioned infections and examines demographic characteristics associated with recorded positivity rates.
Scrub typhus is associated with outbreaks of acute encephalitis syndrome in Uttar Pradesh, India. A case-control study indicated that children residing, playing, or visiting fields; living firewood stored indoors; handling cattle fodder; and practicing open defecation were at increased risk for scrub typhus. Communication messages should focus on changing these behaviors.
COVID-19 transmission was significant amongst Qatar's working population during the March-July 2020 outbreak. The study aimed to estimate risk of exposure for across various workplace settings and demographics in State Qatar.A cross-sectional conducted utilizing surveillance data all workplaces with 10 or more laboratory-confirmed cases COVID-19. These were categorized using a mapping table adapted from North American Industry Classification System (NAICS) codes, 2017 version. then analyzed...
The pursuit of conclusive evidence related to an unanswered foreground (decision-making) question has been the driving factor behind multiple ongoing and planned randomized controlled trials as well meta-analyses. However, a fundamental challenge lies in establishing robust methods for ascertaining whether collection synthesized yielded definitive answer that through process meta-analysis. This article explores evolution attempt address this challenge. These have primarily focused on...
Abstract There is a paucity of evidence about the prevalence and risk factors for symptomatic infection among children. This study aimed to describe coronavirus disease 2019 (COVID-19) its in children adolescents aged 0–18 years Qatar. We conducted cross-sectional all diagnosed with COVID-19 using polymerase chain reaction Qatar during period 1st March 31st July 2020. A generalised linear model binomial family identity link was used assess association between selected infection. total 11 445...
Background: WHO has recommended Visual Inspection with Acetic acid (VIA) or Human Papillomavirus (HPV)DNA testing if feasible, for cervical cancer screening in low income countries. However, the number of womenundergoing is very as a result limited information, inadequate infrastructure and invasive nature ofsampling. Methods: A cross sectional study was carried out comparing HPV DNA detection by Polymerase ChainReaction (PCR) paired urine samples procured from histologically confirmed...
Multimorbidity (MM) is a global concern following the increase in life expectancy, conquering of major infectious diseases, and advances management chronic illnesses. It places substantial burden on patients healthcare systems.This study aims to describe prevalence pattern MM adults among primary users Qatar.A retrospective cross-sectional design.Data were extracted from electronic health records aged 18 years above who registered for care with 27 centres Qatar 1st January 2017 30th June...
Waning immunity following administration of mRNA-based COVID-19 vaccines remains a concern for many health systems. We undertook study to determine if recent reports waning severe disease could have been attributed design-related bias by conducting only among those detected with first SARS-CoV-2 infection. used matched case-control design the base being all individuals infection reported in State Qatar between 1 January 2021 and 20 February 2022. Cases were requiring intensive care (hard...
There is limited seroepidemiological evidence on the magnitude and long-term durability of antibody titers mRNA non-mRNA vaccines in Qatari population. This study was conducted to generate anti-S IgG their dynamics individuals who have completed a primary COVID-19 vaccination schedule. A total 300 male participants received any following BNT162b2/Comirnaty, mRNA-1273, ChAdOx1-S/Covishield, Vaccine Janssen/Johnson, or BBIBP-CorV Covaxin were enrolled our study. All sera samples tested by...
Introduction Contact tracing is an integral component of the overall public health strategy for controlling outbreak infectious diseases such as COVID-19. In addition to conventional contact tracing, Qatar has implemented Ehteraz, a proximity-tracing mobile phone App using global positioning system and Bluetooth technologies. this paper, we aim evaluate accuracy Ehteraz based on WHO criteria compare its effectiveness traditional human led case investigation. Methods A cross-sectional study...
Purpose of review The concept noncollapsibility the odds ratio has intrigued epidemiology community for decades. Despite often being overlooked or negatively perceived, which can lead researchers to prefer collapsible measures, this study highlights beneficial aspects ratio. Recent findings This links recent diagnostic test research with effect measures. Noncollapsibility is a useful characteristic, and its understanding have important implications in medical research. Summary We demonstrate...
Abstract Aims To predict the future health and economic burden of cardiovascular disease (CVD) in type 2 diabetes (T2D) Qatar. Materials Methods A dynamic multistate model was designed to simulate progression fatal non‐fatal CVD events among people with T2D Qatar aged 40‐79 years. First [i.e. myocardial infarction (MI) stroke] were calculated via 2013 Pooled Cohort Equation, while recurrent sourced from REACH registry. Key outcomes MI stroke, years life lived, quality‐adjusted years, total...
The majority of dog-mediated human rabies as well rabies-related deaths are reported from low-income countries Asia and Africa where access to appropriate postexposure prophylaxis is limited or nonexistent. At present, India second in position after China terms having the highest number mobile phone users surpassing United States.In this context, we decided develop a user-friendly, technically less demanding, App for health-care professionals, which accessible even without Internet...
ABSTRACT Background Waning immunity following administration of mRNA based COVID-19 vaccines remains a concern for many health systems. We undertook study SARS-CoV-2 infections, with and without requirement intensive care to shed more light on the duration vaccine effectiveness protection against need care. Methods used matched case-control design base being all individuals first infection reported in State Qatar between 1 Jan 2021 20 Feb 2022. Cases were those requiring while controls who...
