Influenza Is Spreading

The number of flu patients are increasing rapidly.
We get a lot of notifications from schools and nursery homes that they decided to close some classes because of many absence with flu.
The children of my coworkers are also affecting.
My daughter also has got sick since yesterday.Though she is not so bad and I don't know if she got flu or not, but I let her absent from school because I heard many of her friends have got flu since last week.
Now I am wearing a mask when I'm at my office.
Our director told us to wear masks when family members were found to be affected with flu not to transmit to visitors.
I don't like to wear the mask.It mist over my glasses, and it makes me hard to breath.
