Three Pillars of Basic Strategy to combat COVID-19 in Japan

<Overall Goal> Maximization of suppression of transmission and Minimization of socio-economic damage

1. Early detection of and early response to clusters

2. Enhancement of intensive care and the securing of a medical service system for the severely ill, including medical equipment (Ventilator, ECMO, etc)

3. Behavior modification of citizens

Avoidance of high risk environment

Three “C” high risk environments① Closed spaces with insufficient

• Voluntary restraint of mass gathering.• Closure of school.

80% of cases infected in open environment have not transmitted to others.

If these cases are prevented, broad transmission will not occur.

Outpatient facilities for Japanese Returnees and Potential Contacts

○If a public health center decides that a patient is out of the scope of administrative testing, doctors can request the test directly to testing institutes with their own decision.

〇For the purpose of preventing in-hospital infection and ensuring the accuracy of the testing, the test is required to be conducted at outpatient facilities for Japanese Returnees and Potential Contacts.

○Moreover, efforts will be made to expand the number of tests to be conducted with insurance coverage, taking into account future improvement in the preparedness of the private sectors.

Test capacity Tested cases

〇 Capacity to conduct PCR tests for novel corona virus has been increasing.〇 As of now, more PCR test capacity is secured than the actual number of conducted tests.

Total number of tested cases: 52,179 (2/18-3/29)

Novel Corona Virus Test: Capacity and the number of cases tested per day

• We have great concerns about following situation;(1) increased new cases in urban areas,

(2) increased cases with unidentified source.

(3) Rapidly increased confirmed cases and death worldwide.

(4) Many imported cases to Japan.

• Needs to control infection while minimizing socio-economic damage.

• Needs to prevent overwhelming hospitals

• Strengthen the capacity of local government to control the outbreak, considering local situations based on data.
