A few days ago, when my second daughter came out of her room and told me she had a fever, the Ebata family was on the warpath.

First of all, after contacting my family on LINE, I put up a sign saying that the upstairs bathroom was for my second daughter only, and quickly built a DMZ (or not).

I carried the mini-table for eating into the second daughter's room, and threw the bottled drinking water into the room,

She said that she had no taste disorder and had a good appetite, I didn't think that she's infected with corona, however, I took quarantine measures as soon as possible.

And,

"I brought the food to the second daughter's room, wearing a mask and lab coat"

This was a cosplay of a medical professional.

After that, my second daughter's fever came down with over-the-counter medication, so I think that this case is not (probably) caused by the new coronavirus.

I think the university entrance ceremony and the unfamiliar classes must have made her tired.

In that sense, this is the time of year when the risk of infection is high.

Anyway, my second daughter, my eldest daughter, and of course, my husband and I are always at risk of unconscious infection, so we will continue to prevent infection in our home as we have in the past.

However, no matter how careful we are, there will always be times when we get infected.

Infection control measures can only "reduce the probability of infection", not "prevent infection".

"Wearing a mask" only reduces the probability of infection.

Even with "masked dinners," the probability of infection increases from time to time in proportion to the duration of the meal -- This is a natural phenomenon (not even math).

Only "individuals" can "reduce the probability" -- not "governments" (except for the state, where the actions of the people can be controlled by the will of the politicians).

Many people's immune systems will be weakened in April, when a new way of life begins.

Let's be careful with each other.
