Symptoms of Respiratory Illness
9
Known Facts about SARS
  • Less infectious than influenza
  • Incubation 2 to 7 days
  • Infective period?
  • A new virus?
  • Any treatment?
  • Mortality?

10
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

11
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?

12
Guideline for wearing facemask
posted on the Department of Health website on
28/03/2003
  • Wash hands before wearing a facemask.
  • Follow the instructions on the packet carefully,
    if available.
  • In general, when wearing a surgical facemask, the
    following should be noted
  • the facemask should fit snugly over the face
  • the coloured side of the facemask should face
    outside
  • tie all the strings that keep the facemask in
    place or fix the rubber bands of the facemask
    round the ears properly
  • the facemask should fully cover the nose, mouth
    as well as the chin
  • the metallic wire part of the facemask should be
    fixed securely over the bridge of the nose to
    prevent leakage
  • under general circumstances, the surgical mask
    should be changed daily.

13
Guideline for wearing facemask
posted on the Department of Health website on
28/03/2003
  • Put the facemask into a plastic bag and tie it
    properly before putting it into a rubbish bin.
    You may dispose a used facemask concealed in a
    separate bag with the rest of your domestic
    wastes.
  • Replace the facemask immediately if it is damaged
    or soiled.

Wearing a facemask is just one of the ways to
prevent respiratory tract infections. The most
important thing a person should do is to observe
good personal hygiene. For example, wash hands
frequently with liquid soap, especially after
sneezing, coughing or cleaning the nose.
14
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

15
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.

16
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)
