Viral aetiology of severe acute respiratory illness among patients admitted during the 2022 peri-Hajj period.

Introduction: Severe acute respiratory illness (SARI) among pilgrims continues to be an important healthcare issue. The aim of this study was to describe the viral aetiology of patients admitted to hospitals in the holy cities of Makkah and Madinah during the 2022 peri-Hajj period.

Clinical features and outcome of human Mpox (Monkeypox) in Saudi Arabia: An observational study of travel-related cases.

Background: The 2022 Monkeypox virus (Mpox) outbreak had involved multiple countries around the globe. Here, we report clinical features and outcome of human Mpox of the first cases in Saudi Arabia.

Methods: We obtained records of confirmed Mpox cases in Saudi Arabia from the public electronic health information system, Health Electronic Surveillance Network (HESN) and the healthcare providers completed a de-identified structured clinical data collection form.

Seroprevalence of SARS-CoV-2 (COVID-19) among healthcare workers in Saudi Arabia: comparing case and control hospitals.

Healthcare workers (HCWs) stand at the frontline for fighting coronavirus disease 2019 (COVID-19) pandemic. This puts them at higher risk of acquiring the infection than other individuals in the community. Defining immunity status among health care workers is therefore of interest since it helps to mitigate the exposure risk.

Failure of Risk-Adjustment by Test Method for C. difficile Laboratory-Identified Event Reporting.

Using an algorithm including both enzyme immunoassay (EIA) and nucleic acid amplification (NAAT) for Clostridium difficile infection (CDI) diagnosis, we found that the use of NAAT versus EIA almost doubled our hospital-onset CDI laboratory-identified (LabID) event standardized infection ratio (SIR). We recommend that the current risk adjustment approach be modified. Infect Control Hosp Epidemiol 2016:1-3.
