NHK prepared a place that imagined buffet-style restaurant venue on the ship, & conducted an experiment with experts that used fluorescent paint as a virus.

Japan called it "silent pneumonia".

Even at the hospital that accepted infected person on the cruise ship, I felt something was wrong. It is the "pneumonia finding" that was seen in about 1/2 of people who had no symptoms or had mild symptoms when a CT examination was performed.

We called it 'silent pneumonia' in the sense that it is pneumonia that occurs w/o symptoms. Silent pneumonia in which inflammation progresses in lungs w/o any subjective symptoms. Tamura believes this is why symptoms of infected people, thought to be mild, seem to worsen rapidly.

Why aren't US Drs helping their patients?

"If lung damage progresses slowly, it's hard to feel as a subjective symptom. If you don't notice it getting worse & general care intervention is delayed, it can't help person who should have been helped. I think it may be happening."

What was even more surprising to Mr. Yamagishi was that the gene for the virus was also found in the room of an infected person who had no symptoms.
