A Hudson Valley postmaster is reminding people about using coronavirus etiquette at post offices to help stop the spread of COVID-19.

The postmaster, who has seen customers licking envelopes before handing it to him and has observed people sneezing on pens, says there is reason to be concerned because USPS is one of the few businesses allowed to remain open during New York's lockdown.

"What we want the public to do is work with us. We're here to serve you. We want you to be safe and we want to be safe," the postmaster says.

Two postal workers at the processing and distribution center in Westchester tested positive for the virus last week.

USPS says there's no evidence showing COVID-19 can be spread through the mail.

"We have families just like you do that we want to go home to. We want you to be safe and we want to be safe," says the postmaster.
