  6. Symptoms of Respiratory Illness

  7. Known Facts about SARS • Less infectious than influenza • Incubation 2 to 7 days • Infective period? • A new virus? • Any treatment? • Mortality?

  8. How does SARS spread? • NOT airborne • Droplets - via close contact with an infected person • Contaminated working surfaces (e.g. formites, stainless steel) ~ survival up to 6 hours

  9. The wearing of face masks • Healthcare workers looking after suspected/confirmed cases of SARS • Family members of suspected/ confirmed case • Wearing in public area? • N95? Surgical mask?

  10. Prevention of Respiratory Tract Infection (1) • Building good body immunity by having a proper diet, regular exercise and adequate rest, reducing stress and avoiding smoking; • Maintain good personal hygiene, and wash hands after sneezing, coughing or cleaning the nose; • Maintain good ventilation;

  11. Prevention of Respiratory Tract Infection (2) • Avoid visiting crowded places with poor ventilation; • Put on a mask if taking care of a patient with respiratory symptoms and wash hands thoroughly afterwards; • Put on a mask if suffering from respiratory tract infection to reduce the chance of spreading the infection to people around them.

  12. Statistics on community-acquired pneumonia (CAP) • There is no unusual rise in the number of CAP • The causes of CAP are similar to previous years (50% each of known causes and unknown causes)
