The
World Health Organisation has said that the SARS situation in Hong Kong Special Administrative Region has developed features of concern: a
continuing and significant increase in cases with indications that SARS has
spread beyond the initial focus in hospitals.
These developments
WHO says have suggested environmental routes of transmission from a SARS infected person which may be related to
contamination of common systems that link rooms or flats together.
Despite
the implementation of strict measures to control the outbreak, there have
continued to be a small number of visitors to Hong Kong who have been identified as SARS cases after their return from Hong Kong.
The epidemic in
Guangdong Province of China, situated adjacent to Hong Kong, is the largest outbreak of SARS reported and has also shown evidence of spread
in the wider community.
As a measure of precaution WHO is now recommending that persons
travelling to Hong Kong and Guangdong Province of China consider postponing non-essential travel.
WHO has said that this temporary recommendation will be reassessed in the light of the evolution of the
epidemic in the areas currently indicated, and other areas of the world could
become subject to similar recommendations if the situation demands.
The outbreak of severe acute respiratory syndrome (SARS) continues in the affected
areas* : Canada (Toronto), China (Guangdong Province, Hong Kong Special Administrative Region of China, Shanxi Province, Taiwan Province), Singapore (Singapore), Vietnam (Hanoi).
The agent causing SARS is under intensive international study, but as of today it has not been fully characterized, and there is no vaccine or other prophylaxis available.
Since WHO issued the global alert on the 12th of March national authorities
have implemented heightened surveillance for cases of SARS and where such cases have been identified their prompt isolation has prevented further
spread of the disease in virtually all countries. For instance the outbreak in
Hanoi has passed its peak and no new cases have been identified for the last week.
Please note that
WHO's recommendation applies only to travellers entering Hong Kong Special Administrative Region of China and Guangdong
Province of China, not to passengers directly transiting through international airports within those areas.
*WHO has defined affected areas as an area in which local chain(s) of transmission of SARS is/are occurring as reported by the national public health authorities.
