Abstract There is limited information concerning the viral load of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in aerosols deposited on environmental surfaces and the effectiveness of infection prevention and control procedures on eliminating SARS-CoV-2 contamination in hospital settings. We examined the concentration of SARS-CoV-2 in aerosol samples and on environmental surfaces in a hospital designated for treating severe COVID-19 patients. Aerosol samples were collected by a microbial air sampler, and environmental surfaces were sampled using sterile premoistened swabs at multiple sites. Ninety surface swabs and 135 aerosol samples were collected. Only two swabs, sampled from the inside of a patient's mask, were positive for SARS-CoV-2 RNA. All other swabs and aerosol samples were negative for the virus. Our study indicated that strict implementation of infection prevention and control procedures was highly effective in eliminating aerosol and environmental borne SARS-CoV-2 RNA thereby reducing the risk of cross-infection in hospitals.

AbstractObjectivesTo confirm the incidence of perioperative SARS-CoV-2 infection and associated mortality after surgery.Design and settingAnalysis of routine electronic health record data from National Health Service (NHS) hospitals in England.MethodsWe extracted data from Hospital Episode Statistics in England describing adult patients undergoing surgery between 1st January 2020 and 31st October 2020. The exposure was SARS-CoV-2 infection defined by ICD-10 codes. The primary outcome measure was 90-day in-hospital mortality. Data were analysed using multivariable logistic regression adjusted for age, sex, Charlson co-morbidity index, index of multiple deprivation, presence of cancer, surgical procedure type and admission acuity. Results are presented as n (%) and odds ratios (OR) with 95% confidence intervals.ResultsWe identified 1,972,153 patients undergoing surgery of whom 11,940 (0.6%) had SARS-CoV-2. In total, 19,100 (1.0%) patients died in hospital. SARS-CoV-2 infection was associated with a much greater risk of death (SARS-CoV-2: 2,618/11,940 [21.9%] vs No SARS-CoV-2: 16,482/1,960,213 [0.8%]; OR: 5.8 [5.5 – 6.1]; p<0.001). Amongst patients undergoing elective surgery 1,030/1,374,985 (0.1%) had SARS-CoV-2 of whom 83/1,030 (8.1%) died, compared with 1,092/1,373,955 (0.1%) patients without SARS-CoV-2 (OR: 29.0 [22.5 −37.3]; p<0.001). Amongst patients undergoing emergency surgery 9,742/437,891 (2.2%) patients had SARS-CoV-2, of whom 2,466/9,742 (25.3%) died compared with 14,817/428,149 (3.5%) patients without SARS-CoV-2 (OR: 5.7 [5.4 – 6.0]; p<0.001).ConclusionsThe low incidence of SARS-CoV-2 infection in NHS surgical pathways suggests current infection prevention and control policies are highly effective. However, the high mortality amongst patients with SARS-CoV-2 suggests these precautions cannot be safely relaxed.Summary boxesWhat is already known on this topicHigh mortality rates have been reported amongst surgical patients who develop COVID-19 but we don’t know how this compares to the concurrent surgical population unaffected by COVID-19.Strict infection prevention and control procedures have substantially reduced the capacity of surgical treatment pathways in many hospitals.The very large backlog in delayed and cancelled surgical procedures is a growing public health concern.What this study addsFewer than 1 in 100 surgical patients are affected by COVID-19 in the English National Health Service.Elective surgical patients who do develop COVID-19 are 30 times more likely to die while in hospital.Infection prevention and control procedures in NHS surgical pathways are highly effective but cannot be safely relaxed.

The Manual of Infection Prevention and Control provides practical guidance on all aspects of healthcare-associated infections (HAIs). It outlines the basic concepts of infection prevention and control (IPC), modes of transmission, surveillance, control of outbreaks, epidemiology, and biostatistics. The book provides up-to-date advice on the triage and isolation of patients and on new and emerging infectious diseases, and with the use of illustrations, it provides a step-by-step approach on how to perform hand hygiene and how to don and take off personal protective equipment correctly. In addition, this section also outlines how to minimize cross-infection by healthcare building design and prevent the transmission of various infectious diseases from infected patients after death. The disinfection and sterilization section reviews how to risk assess, disinfect and/or sterilize medical items and equipment, antimicrobial activities, and the use of various chemical disinfectants and antiseptics, and how to decontaminate endoscopes. The section on the prevention of HAIs reviews and updates IPC guidance on the prevention of the most common HAIs, i.e. surgical site infections, infections associated with intravascular and urinary catheters, and hospital- and ventilator-acquired pneumonias. In view of the global emergence of antimicrobial resistance to the various pathogens, the book examines and provides practical advice on how to implement an antibiotic stewardship programme and prevent cross-infection against various multi-drug resistant pathogens. Amongst other pathogens, the book also reviews IPC precautions against various haemorrhagic and bloodborne viral infections. The section on support services discusses the protection of healthcare workers, kitchen, environmental cleaning, catering, laundry services, and clinical waste disposal services.

The Institute of Mental Health in Singapore continues to attempt to prevent the introduction of COVID-19, despite community transmission. Essential services are maintained and quarantine measures are currently unnecessary. To help similar organizations, strategies are listed along three themes: sustaining essential services, preventing infection, and managing human and consumable resources.

Healthcare workers have good perception towards infection prevention, but there has been a poor practice towards it. Therefore, the aim of this study was to explore barriers to practice of infection prevention and control practice in teaching hospitals in Amhara region. A phenomenological approach used to explore the lived experience of healthcare workers and management staffs towards infection prevention practice and control. The data was collected from ten in-depth interviews and 23 focus group discussion participants, by face to face interview using open ended interview performed in safe and quiet places. Data was managed using OpenCode software version 4.03 and contents were analyzed thematically. Totally ten different barriers were identified, such as availability of facilities, shortage of material supply, lack of maintenance of facilities and equipment, high patient flow, experience, emergency situation, healthcare worker behaviour and healthcare worker’s information about infection prevention, low awareness of patients and visitors and overflow of families and visitors to the hospital. For effective infection prevention practice implementation, barriers should be considered via identifying specific organizational, healthcare worker, patients and visitors as targets.
