(4) Strict Risk Management
• Local authorities have been instructed to draw up
•
•
detailed “Action Plan” for a possible outbreak. All
prefectural governments have developed their action
plans.
“Management Guideline for Preventing In-Hospital
Infection” has been drafted and published (April 7).
Meeting of directors of national public health lead offices
was held, and directors were briefed on the national
policy and action plan during a possible outbreak (May

5. Promotion of International Cooperation
* Dispatching medical doctors to affected countries and
cooperating on researches in diagnosis and treatments.
WHO speculates SARS affects
little in this winter（reasons as below／in
SARS Update no. 89: June 26）
• Firstly, today’s international public heath care system is able to
•
•
•
•
shift to the higher level of alert immediately
Secondly, medical specialists in the world know what should they
do to control infectious disease, as there is a long history of
infection control.
Thirdly, it is expected to develop the rapid and reliable diagnostic
examination on SARS, which can be adopted at the beginning of
treatment.
Fourthly, enforcement of discretion on mass epidemics was
decided at the WHO general meeting in May.
Lastly, SARS epidemics show that it is important to release the
case of any disease immediately, which has the possibility of
spreading out around the world.
Problem of Prevention from SARS
Epidemics in Japan
1. Deep understanding of information
・Information system offering by TV, Radio and etc.
・Common ownership of scientific and objective information
2. Improvement of detective methods for SARS patients
・High detailed investigation for person contacted to SARS
・ Common ownership on investigative methods for outbreak of
SARS
3. Establishment of In-Hospital infection control system
・key point; success of in-hospital infection control
4. Flexibility of early detective system
・early detection of aged patients without fever and severe
symptoms
5. Cooperation of implementation for international
discretion
Conclusion
• Fortunately we did not have any SARS patients in
•
Japan, it is necessary to build up a cooperation
system among Asian Pacific countries, including
exchanging information, in order to prevent the
potential SARS epidemics toward this winter.
Furthermore, concerning risk management of our
country, there are some future issues, such as to
ensure out-of-hours service at each section in the
government, in the local governments, and in public
health care centers, and to build up a transportation
system for the patients.
