No, just a bad cold.

不严重，就是重感冒。

"There's a huge misconception that if you have a pretty bad cold, antibiotics will just take care of it," says Dr. D. "But the common cold (and the flu) is caused by a virus."

D博士说：“有一个巨大的误区是如果你有很严重的感冒，抗生素将会治好它。但是普通的感冒(或者流感)是由病毒引发的”。

Well, you see, I caught a bad cold this morning. You'd better not open it. Just leave the door open. Will that be all right?

这个嘛，你知道，我今早得重感冒了。你最好还是别开了。只开门，行吗？
