Health care-associated measles outbreak in pediatric wards in a tertiary care hospital: Challenges and Swiss cheese model enforcement for patient safety.

Introduction: Measles is one of the most contagious of all infectious diseases, for example, up to 9 out of 10 susceptible people with close contact to a measles patient will develop measles. In countries where measles is rare, transmissions in health care facilities have been a key factor in amplifying outbreaks OBJECTIVES: Describe the hospital transmission of measles among unvaccinated children in pediatric service, challenges faced and recommendations for health care settings by applying the Swiss cheese model.

Method: Between December 2019 and January 2020; multiple exposures to measles cases occurred.

Seroconversion of COVID-19 in Frontline Healthcare Workers in a Tertiary Care Hospital in Oman.

Objectives: This research aimed to study the seroconversion among frontline staff at the highest risk of exposure to SARS-CoV-2 infections, including emergency department, critical care, and COVID-19 isolation wards in all healthcare job categories.

Methods: We conducted a prospective cohort study on the incidence of seroconversion among frontline health care workers (HCWs) at the Royal Hospital, Muscat, Oman. Two sera were collected 12 weeks apart to look for seroconversion.

Characteristics of healthcare workers infected with COVID-19: A cross-sectional observational study.

Introduction: Coronavirus disease 2019 (COVID-19) is a new emerging infectious disease, first identified in China in December 2019, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study describes the characteristics of healthcare workers (HCWs) who tested positive for COVID-19 in a tertiary care hospital in Oman.

Methods: This was a cross-sectional descriptive analysis of HCWs with COVID-19.

First report of human infection with avian influenza A(H9N2) virus in Oman: The need for a One Health approach.

Following the detection of the first human case of avian influenza A subtype H9N2 in 1998, more than 40 cases were diagnosed worldwide. However, the spread of the virus has been more remarkable and significant in global poultry populations, causing notable economic losses despite its low pathogenicity. Many surveillance studies and activities conducted in several countries have shown the predominance of this virus subtype.

Rates of central line-associated bloodstream infection in tertiary care hospitals in 3 Arabian gulf countries: 6-year surveillance study.

The objective of this study was to compare central line-associated bloodstream infection (CLABSI) rates in Gulf Cooperation Council (GCC) states with those of the U.S. National Healthcare Safety Network (NHSN) and International Nosocomial Infection Control Consortium (INICC) using pooled data from 6 hospitals in 3 GCC countries.

Rates of catheter-associated urinary tract infection in tertiary care hospitals in 3 Arabian Gulf countries: A 6-year surveillance study.

Background: The true burden of catheter-associated urinary tract infections (CAUTIs) remains largely unknown because of a lack of national and regional surveillance reports in Gulf Cooperation Council (GCC) countries. The purpose of this study was to estimate location-specific CAUTI rates in the GCC region and to compare them with published reports from the U.S.

Ventilator-associated pneumonia rates in critical care units in 3 Arabian Gulf countries: A 6-year surveillance study.

Background: Data estimating the rates of ventilator-associated pneumonia (VAP) in critical patients in Gulf Cooperation Council (GCC) countries are very limited. The aim of this study was to estimate VAP rates in GCC hospitals and to compare rates with published reports of the U.S.

Postrenal transplant renopulmonary zygomycosis with vascular aneurysms responded to surgical treatment and salvage therapy with posaconazole after failure to respond to liposomal amphotericin.

Background: Zygomycosis is a difficult to treat and frequently fatal infection affecting immunocompromised and (rarely) immunocompetent patients. It requires a multifaceted approach involving elimination of predisposing factors, surgical debridement, and antifungal therapy.

Case Report: We report the case of a postrenal transplant patient who developed disseminated zygomycosis with vascular aneurysms after receiving empirical voriconazole treatment for presumed pulmonary fungal infection in addition to immunosuppression and methylprednisolone pulses for presumed graft rejection, as renal biopsy was declined.

Characterization of OXA-181, a carbapenem-hydrolyzing class D beta-lactamase from Klebsiella pneumoniae.

Klebsiella pneumoniae KP3 was isolated from a patient transferred from India to the Sultanate of Oman. K. pneumoniae KP3 was resistant to all β-lactams, including carbapenems, and expressed the carbapenem-hydrolyzing β-lactamase OXA-181, which differs from OXA-48 by four amino acid substitutions.

NDM-1-producing Klebsiella pneumoniae isolated in the Sultanate of Oman.

Objectives: To analyse the mechanisms responsible for multidrug resistance in two carbapenem-resistant Klebsiella pneumoniae isolates recovered from patients hospitalized in Oman.

Methods: PCR and sequencing were used to search for β-lactamase and 16S RNA methylase genes. Multilocus sequence typing was used to determine the sequence type (ST) of each isolate.
