What is a state of emergency declaration?

Yesterday in America、Today there was news that a state of emergency has been declared in Spain.。I've heard of it、What exactly is a state of emergency declaration?

The state of emergency is declared、In response to crises in the management of the nation due to disasters, etc.、The government may invoke special laws due to emergencies.。Armed attack on target、civil unrest、riot、terrorism、In addition to large-scale disasters, etc.、bird flu、There also seems to be epidemics such as norovirus.。

This time it's due to the new coronavirus.、It's probably an epidemic。Is this part of the announcement that the country is in dire straits?。

It is also spreading in Europe、My impression is that the number of infected people in Japan is increasing day by day.。
If you think about it, doctors and nurses are also having a hard time.。The risk of getting infected is very high、diagnosis、treatment has to be done。Even if there is a reward for that.。All I can do is pray that you do your best...

I want it to end soon。
