How can they look down persons who are scrambling for hand masks ?

Currently, during the global outbreak of COVID-19 (the WHO has identified it as a "pandemic" today), many are seeking face masks to protect themselves.

The other day, I was surprised to see a long line in front of the drugstore.

As I said the other day, I'm not worried about the lack of toilet paper.

But the lack of a face mask is a bit uneasy for me.

What I did not participate in this riot was that I had a serious hay fever, and my wife purchased a large amount of face masks in advance every year.

"In other words, just lucky"

COVID-19 has been observed to be a mysterious phenomenon that breaks the common sense of viral diseases.

In particular, when I heard the news of "a person who turned from a positive reaction to a negative reaction turned positive again", I was almost shocked to drop the dishes on the floor.

"COVID-19 ignores the basics of immunity so far"

The transition from a positive reaction to a negative reaction means "acquired immunity".

In other words, it has been grasped as a scientific symbol of Mito Komon, like "I will never be infected with the same virus for a lifetime."

However, there are exceptions.

HIV virus. It has a troublesome property. This guy is always changing shape, and continues to escape attacks from immunity.

However, the spread rate of the HIV virus is terribly slow because the infection condition is limited to mucosal infection (SEX etc.) or blood transfusion etc.

However, the incubation period until onset is terribly long, from several years to 10 years. It has the property of spreading widespread without being noticed.
