Incorporation of droplet and contact precautions in standard practice • (c) Handwashing is mandated after each patient contact • (d) Protective clothing, for example, white coat, or gown should be worn in clinic areas within the designated clinic boundary. Precaution focusing on patients/clients • Advising all patients/clients specifically requiring those with respiratory signs/symptoms or fever to wear surgical mask Patient triage • (i) Patients asked to self-identify if high risk. • (ii) A client at higher risk of infection must wear a surgical mask and the consultation should be in a designated room. • (iii) N95 mask, gloves, goggles and protective clothing should be worn during high risk procedures. Designated room • (a)Good ventilation and preferably separate hand washing facilities. • (b) Avoid aerosol-generating procedure. Designated room • (c) Wastes should be placed in waste bags, which are tied and put in covered containers for disposal in the normal channels. • (d) Contaminated PPE and other items should not be brought into non-clinic areas. Following the care of a patient suspected with or known to have novel influenza • (a) The area should be closed for disinfection as soon as possible. • (b) Consultation area/equipment should be disinfected with 1:49 household bleach (or 70% alcohol for metallic surfaces). Thank You Alert Response Level Medical Services • Stockpile medications for public hospitals and clinics. (HA) • Formulate clinical management guideline. (HA) • Monitor bed occupancy, and review mobilization/compliance with admission guidelines. • Assess and plan for scaling down nonemergency activities. (HA) Serious Response Level Essential medical services • Set up designated clinics and protocol for triaging patients with influenza-like illness at primary care level. (HA) • Isolate and treat confirmed cases in designated hospitals. (HA) Serious Response Level Essential medical services • Update / revise clinical guidelines on management/admission criteria for various specialties. • Reduce non-urgent and nonemergency services. (HA) • Discussion with private hospitals on patients transfer/diversion/sharing workload. (HA) Emergency Response Level Essential medical services • Additional hospitals for isolation • Further re-organize or reduce nonurgent services • Mobilize convalescent hospitals/wards and private sector to increase capacity to treat acute cases Emergency Response Level Essential medical services • Updated guidelines and protocols • Mobilize more designated clinics and centres in collaboration with the private sector and voluntary agencies • Review and update protocols on research projects
