I'm not a dr, but I highly doubt 20 mins in the freezer killed coronavirus (assuming it had coronavirus in the first place).

The freezer is what, like 0F? When this whole outbreak started, it was cold in some areas of China -- like we're talking 0F to 20F. It still spread like wildfire anyways.

Also, there are U.S. states that are cold as hell in February (0F and below), and even those states experienced an outbreak.

Somewhat cold (e.g., 0F) really doesn't kill coronavirus, nor does high heat (just look at Singapore and Australia where it's warm/summer). It kinda just chillaxes wherever it feels like.

If we knew how to kill it with temperature, we would have figured it out already and it would be published as a paper, and the media would be talking about it.

In the future, either don't touch the plastic for 72 hours, or use sanitizing materials (wipes, hand sanitizer, etc.). Not to be an @ss, but you technically would have already caught it by touching the bottle w/o sanitizing it first, regardless if you put it in the freezer or not.
