The Postal Service has stated that so far it has experienced only minor operational impacts as a result of the COVID-19 pandemic, and maintains that as an essential service it remains ready and able to deliver medications, social security checks, on-line purchases and so on.
It also cited language from the World Health Organization saying that “the likelihood of an infected person contaminating commercial goods is low and the risk of catching the virus that causes COVID-19 from a package that has been moved, travelled, and exposed to different conditions and temperature is also low.”
It also called attention to the following statement from the CDC, “in general, because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures. Coronaviruses are generally thought to be spread most often by respiratory droplets. Currently there is no evidence to support transmission of COVID-19 associated with imported goods and there have not been any cases of COVID-19 in the United States associated with imported goods.”
