- 3. What is Coronavirus& COVID-19 Clinical Excellence Commission 3 • Coronaviruses are a large family of viruses, some cause illness in humans, and others cause illness in animals, such as bats, camels, and civets. • Human coronaviruses cause mild illness, such as the common cold • Severe acute respiratory syndrome (SARS) is a viral respiratory illness caused by a coronavirus, called SARS-associated coronavirus (SARS-CoV) • Previous Coronaviruses have included SARS- CoV and MERS-CoV • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new strain of coronavirus that has not been previously identified in humans.
- 4. Human Coronavirus Origins Themost likely ecological reservoirs for coronaviruses are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified. Clinical Excellence Commission 4
- 5. Coronaviruses Coronaviruses belong tothe Coronaviridae family in the Nidovirales order Corona represents crown-like spikes on the outer surface of the virus; thus, it was named as a coronavirus Coronaviruses are enveloped viruses, minute in size (65–125 nm in diameter) and contain a single-stranded RNA as a nucleic material, size ranging from 26 to 32kbs in length Clinical Excellence Commission 5
- 6. COVID-19 The virus thatcauses COVID-19 is known as SARS-CoV-2 It appears to have first emerged in Wuhan, China, in late 2019. The outbreak has since spread across China to other countries around the world. By the end of January, the new coronavirus had been declared a public health emergency of international concern by the WHO. The most commonly reported symptoms include a fever, dry cough and tiredness, and in mild cases people may get just a runny nose or a sore throat. In the most severe cases, people with the virus can develop difficulty breathing, and may ultimately experience organ failure. Some cases are fatal. Clinical Excellence Commission 6

The WHO has declared that the official new name for the virus that also formerly went by the names “2019 novel coronavirus” or “2019-nCoV” is now to be known as “SARS-coV-2” which causes COVID-19. This name change is to differentiate it from other coronavirus outbreaks that include the common cold, but also the severe acute respiratory syndrome (SARS- CoV) and Middle East Respiratory Syndrome (MERS-CoV) which have previously afflicted the world.
- 13. Australian National Response TheAustralian Government’s health response to the COVID-19 outbreak aims to: • minimise the number of people becoming infected or sick with COVID-19 • minimise how sick people become and the mortality rate • manage the demand on our health systems • help you to manage your own risk and the risk to your family and community Clinical Excellence Commission 13

Australian Department ofHealth Government and private agencies are working together to support the Australian Government response • regularly reviewing response • moving resources into activities that are working well • scaling back activities that are not working Clinical Excellence Commission 15
- 16. NSW Health Response Infectionwith COVID-19 is a notifiable condition under the NSW Public Health Act, so all cases and suspected cases must be reported by doctors and pathology to NSW Health NSW Health have implemented a range of measures to promptly identify cases of COVID-19 infection and prevent transmission in NSW Leading & Coordinating a Statewide Response Clinical Excellence Commission 16
- 17. NSW Health Responseto COVID-19 Should a person in NSW be confirmed to have COVID-19 infection, NSW Health has procedures in place to identify people they have been in close contact with. Those people are provided with advice about self-isolation to minimise spread of the infection. NSW Health response included: • establishing a NSW COVID-19 Clinical Council and 30 Clinical Communities of Practices across key clinical specialities to support the response to COVID-19 • providing advice to GPs, pharmacists, emergency departments, and the broader health system on the situation as it evolves to enable possible cases to be rapidly identified, diagnosed and managed • developing diagnostic tests through public health laboratories to rapidly diagnose cases • offering testing at public COVID-19 clinics throughout the state • managing any cases with appropriate infection prevention and control and public health measures to minimise the risk to health care workers and the community • providing regular updates to the community, through media briefings, media releases and social media including in community languages Clinical Excellence Commission 17
- 18. Case definition –confirmed case A person who: i. tests positive to a validated specific SARS-CoV-2 nucleic acid test; OR ii. has the virus isolated in cell culture, with PCR confirmation using a validated method; OR iii. undergoes a seroconversion to or has a significant rise in SARS-CoV-2 neutralising or IgG antibody level (e.g. four-fold or greater rise in titre). https://www1.health.gov.au/internet/main/publishing.nsf/Content/7A8654A8CB144F5FCA2584F8001F91E2/$File/COVID-19-SoNG-v3.3.pdf Clinical Excellence Commission 18

- 21. Suspect case Clinical andpublic health judgement should be used to determine the need for testing in hospitalised patients and patients who do not meet the clinical or epidemiological criteria. Clinical Excellence Commission 21
- 22. Epidemiological criteria In the14 days prior to illness onset: • Close contact with a confirmed or probable case • International or interstate travel • Passengers or crew who have travelled on a cruise ship • Healthcare, aged or residential care workers and staff with direct patient contact • People who have lived in or travelled through a geographically localised area with elevated risk of community transmission, as defined by public health authorities Clinical Excellence Commission 22
- 23. COVID-19 Close Contactdefinition Clinical Excellence Commission 23 A close contact is defined as requiring: • face-to-face contact in any setting with a confirmed or probable case, for greater than 15 minutes cumulative over the course of a week, in the period extending from 48 hours before onset of symptoms in the confirmed or probable case, or • sharing of a closed space with a confirmed or probable case for a prolonged period (e.g. more than 2 hours) in the period extending from 48 hours before onset of symptoms in the confirmed or probable case

- 25. Role of ClinicalExcellence Commission Clinical Excellence Commission 25
- 26. General principles forinfection prevention and control to prevent or limit transmission of COVID-19 • Early recognition of patients who have suspected, probable or confirmed COVID-19 • Physical distancing during COVID-19 outbreak • Respiratory hygiene and cough etiquette • Management of patients with acute respiratory symptoms and/or suspected or proven COVID19 • Application of Standard Precautions for all patients at all times • Implement Transmission-Based Precautions based on risk assessment Clinical Excellence Commission 26
- 27. Isolate and applyinfection prevention & control precautions • Standard precautions, including hand hygiene (5 Moments) for all patients. Patients and health workers should observe respiratory hygiene and cough etiquette. • Transmission-based precautions for patients with suspected, probable or confirmed COVID-19: - Contact and droplet precautions for routine care of patients. - Contact, droplet and airborne precautions for respiratory aerosol generating procedures (AGPs). Clinical Excellence Commission 27
- 28. Aerosol-generating procedures (AGPs) Aerosolgenerating procedures (AGPs) are defined as any medical and patient care procedure that results in the production of airborne particles (aerosols) less than 5 micrometres (µm) in size which can remain suspended in the air, travel over a distance and may cause infection if they are inhaled. Examples of AGPs can be found on Coronavirus Disease 2019 (COVID-19) CDNA National Guidelines for Public Health Units Clinical Excellence Commission 28
- 29. COVID-19 transmission Generally, SARSCoV-2 is spread by larger respiratory particles of liquid referred to as droplets. These larger droplet particles tend to fall on adjacent surfaces (e.g. floor, tabletop) relatively quickly and do not travel long distances. Travelling over long distances on air currents is generally not a significant factor in the spread of this infection. Clinical Excellence Commission 29
- 30. Precautions for COVID-19 Contactand droplet precautions Addition of airborne precautions for respiratory AGPs Hand hygiene Environmental cleaning Cleaning of shared patient care equipment Clinical Excellence Commission 30
- 31. On presentation oradmission to hospital the patient should be: o given a surgical mask to put on, and o placed in a single room (ensuring air does not circulate to other areas) o placed in a negative pressure room (in the event of AGPs being performed). o If transfer outside the room is essential, the patient should wear a surgical mask during transfer and follow respiratory hygiene and cough etiquette. Clinical Excellence Commission 31
- 32. Contact and dropletprecautions: • For close contact <1.5meter between health worker and patients the following PPE is safe and appropriate and should be put on before entering the patient’s room: o An apron or a long-sleeved impervious gown o surgical mask o Safety glasses or face shield o disposable nonsterile gloves when in contact with patient (hand hygiene before donning and after removing gloves) Clinical Excellence Commission 32
- 33. Personal protective equipmentfor AGPs • P2/N95 respirators are used for airborne precautions when respiratory AGPs are conducted on patients with suspected, probable or confirmed COVID-19 and must be discarded following the AGP along with • Fluid resistant long-sleeved or isolation gown • Eye protection - safety glasses or face shield • Disposable nonsterile gloves when in contact with the patient (hand hygiene before donning and after removing gloves) Clinical Excellence Commission 33
- 34.
- 35. P2/N95 Mask FitCheck Unless used correctly, i.e. with fit-checking, a P2/N95 respirator (mask) is unlikely to protect against airborne pathogen spread. An air-tight seal may be difficult to achieve for people with facial hair. Fit checking with a range of P2/N95 respirators must occur to assess the most suitable one to achieve a protective seal. If a tight seal cannot be achieved, facial hair should be removed. Clinical Excellence Commission 35

- 37. Infection prevention &control principles • Environmental Cleaning using a hospital grade and TGA approved disinfectant. • Waste Management follows routine clinical and non-clinical waste processes • Utensils follows routine cleaning process • Linen Management follows normal processes. • Hand Hygiene using ABHR and/or hand washing. • Respiratory hygiene and cough etiquette principles apply • PPE Transmission based precautions Clinical Excellence Commission 37
- 38. 38 • Staff educationfor donning and doffing PPE is undertaken for staff managing cases • Opportunity to ensure training of staff is up to date - Limited stocks of PPE should not be used for training and other models of training should occur PPE Removing PPE There are a variety of ways to safely remove PPE without contaminating your clothing, skin, or mucous membranes with potentially infectious materials. See two examples below: Example 1 1. Gloves 2. Gown or Apron 3. Goggles or Face shield 4. Mask or Respirator Example 2 1. Gown and Gloves (in a combined motion) 2. Goggles or Face shield 3. Mask or Respirator Perform hand hygiene immediately after glove removal, before removing face protection, before removing mask/respirator and after removal of any contaminated item Hand Hygiene

- 41. Advice for healthworkers, staff, healthcare students and volunteers in NSW • NSW Health recommends that any HW, healthcare student or volunteer with respiratory symptoms or unexplained fever (≥37.50C) should be tested for COVID-19 and immediately self-isolate. They should not return to work duties until they have been tested and cleared from COVID-19 infection • Symptoms of COVID-19 include fever (≥37.50C), cough, sore/scratchy throat and shortness of breath. Other reported symptoms of COVID-19 include loss of smell, loss of taste, runny nose, muscle pain, joint pain, diarrhoea, nausea/vomiting and loss of appetite. • The HW, healthcare student or volunteer must also follow the home isolation guidance for people suspected to have COVID-19. There are a number of COVID-19 Testing Clinics throughout NSW. General Practitioners and Emergency Departments can also perform COVID-19 testing Clinical Excellence Commission 41
- 42. Advice for healthworkers, staff, healthcare students and volunteers in NSW • If a HW, healthcare student or volunteer is tested positive for COVID-19 they must follow the NSW Health Release from Isolation criteria before returning to work. • If a HW, healthcare student or volunteer has tested negative for COVID-19 and continues to experience respiratory symptoms or unexplained fever, they should be medically assessed prior to returning to work duties • If a HW has been informed that they are a close contact for COVID-19 by either the healthcare facility or local Public Health Unit, they must inform their manager or supervisor.
