Masks are out of stock?

Japanese people are very sensitive about virus.

After the government announced that more than 160 cases of swine flu are confirmed in Osaka and Kobe, people started buying masks to protect against virus.

Suddenly, it becomes so hard to find masks in everywhere.  Even in Tokyo, it is difficult to find masks.

Some companies had already bought a huge stock of masks to hand it for their workers.  No wonder people can't find a mask at drug stores.
