Drug stores are currently having a tough time keeping hand sanitizer in stock.
"We sold out of the masks first and then the hand sanitizer went a little bit after. I guess people were nervous about the potential spread," said Steve Theodorou, pharmacy manager of Dake's Drug Store.
Theodorou said it's unclear when wholesalers will be able to send out the next shipment.

"Some of them don't even give an estimated release date. Some are saying the end of this month," Theodorou said.
The CDC recommends using alcohol-based sanitizer with at least 60 percent alcohol if soap and water aren't available.
There are also ways to make your own sanitizer by using rubbing alcohol, but experts warn to be sure the ingredients are measured correctly to protect your skin.
"Most rubbing alcohol is like 70 percent isopropyl and I think you'll get essentially the same effect as far as killing off viruses and bacteria," Theodorou said.
Families are also taking more precautions at public events and gatherings.
