Question: Can the coronavirus live on my mail or on packages?

Answer passage (source: CDC):
page_title: What Mail and Parcel Delivery Drivers Need to Know about COVID-19
section_headers: As a mail and parcel delivery driver (such as for Amazon, DHS, FedEx,
Purolater, UPS, USPS), how can I protect myself and others?
section_content: As a mail and parcel delivery driver, potential sources of exposure include
having close contact with co-workers or delivery recipients, or when you touch
surfaces touched or handled by a person who has COVID-19.
Stay home if you are sick

If you develop a fever or symptoms, such as cough or difficulty breathing, call your healthcare provider for medical advice before visiting their office.
You should not return to work until the criteria to discontinue home isolation are met, after talking with your doctor.

Wear a cloth face covering

CDC recommends wearing cloth face coverings in public settings where other social distancing measures are hard to do, especially in areas that have high rates of COVID infection.
Cloth face coverings may help prevent people who don’t know they have the virus from spreading it to others.
These face coverings are not surgical masks or respirators and are not appropriate substitutes for them in workplaces where masks or respirators are recommended or required.

Limit Contact

Practice contactless deliveries whenever you can. Contactless deliveries allow you to leave a delivery at a doorstep, move back to a distance greater than 6 feet away while verifying receipt of the delivery with the recipient (if required), and try to do everything electronically whenever you can (e.g., in an app or over a phone). This eliminates the need for close contact between you and delivery recipient.
Maintain a distance 6 feet or greater from others you might meet or need to speak to while making your deliveries.
Limit contact with frequently touched surfaces during deliveries, such as doorbells or door handles. Use a foot, shoulder, elbow, hip, or forearm when opening doors, instead of hands, if possible.
Avoid sharing scanners, pens, or other tools with customers.
If you are wearing machine-washable work gloves normally worn for the job throughout your shift, do not touch your face with gloved hands. Remove them and wash hands before eating. At the end of the work shift, remove the gloves, store them for washing, and wash your hands. When doing laundry, wash gloves using the warmest appropriate water setting and dry them completely.

Clean and Disinfect

If surfaces are visibly dirty, they should be cleaned with detergent or soap and water prior to disinfection.
Carry cleaning and disinfectant disposable wipes, if available, and a trash bag with you in your vehicle. Follow the directions on the cleaning product’s label. 
Clean and disinfect frequently touched surfaces of the delivery vehicle (particularly if it is shared) at the start and end of the shift. These include the steering wheel, gearshift, signaling levers, and door handles.
Wipe down pens, clipboards, and electronic signature pads after each use with the public if shared when performing a delivery.


Appropriate disinfectants for hard non-porous surfaces include: 
EPA’s Registered Antimicrobial Products for Use Against Novel Coronavirus SARS-CoV-2external icon
Diluted household bleach solutions prepared according to the manufacturers label for disinfection, if appropriate for the surface
Alcohol solutions with at least 70% alcohol.



Practice Everyday Preventive Actions

Avoid touching your eyes, nose, or mouth.
Proper hand hygiene is an important infection control measure. Keep in mind where you can access and use facilities with soap and water during your shift. Wash your hands regularly with soap and water for at least 20 seconds or use an alcohol-based hand sanitizer containing at least 60% alcohol.
Key times to clean hands include: 
Before, during, and after preparing food
Before eating food
After using the toilet
After blowing your nose, coughing, or sneezing



Additional times on the job to clean hands include: 

Before and after work shifts
Before and after work breaks
After putting on, touching, or removing cloth face coverings
Before and after making deliveries, including after picking up from drop-boxes and customer pickups
After touching frequently touched surfaces, such as doorbells or door handles
Before wearing and after removing cold-weather gloves
Before and after pumping gas



Carry tissues in your vehicle to use when you cough, sneeze, or touch your face. Throw used tissues in the trash.



Reviewer feedback on this answer:
The answer is irrelevant to the question. This answer contains guidelines for mail and parcel delivery driver to protect themselves against Covid-19 and the question is asking of whether or not coronavirus can live on mail or packages.
This is general advice for postal carriers. It answers the question in a roundabout way, but that answer is buried in lots of unrelated text.

What is COVID-19?
section_content: Coronavirus Disease 2019 (COVID-19) is a new disease, and we are still
learning about how it spreads and the severity of illness it causes. The
virus that causes COVID-19 is believed to spread person-to-person between
people who are in close contact (being within about 6 feet) with one another.
Some people without symptoms may be able to spread the virus.
The virus likely spreads primarily through saliva or mucus droplets produced
when an infected person coughs, sneezes, or talks. This is somewhat like how
the flu (influenza) and other infections such as the common cold spread.
These droplets can land in the mouths or noses of people who are nearby or
possibly be breathed in. Droplets can remain on surfaces such as countertops
and doorknobs for hours to days.

Reviewer feedback on this answer:
It answers the question in a roundabout way by saying that the virus mostly spreads through airborne droplets, but can be found on surfaces. It doesn't actually address mail specifically, though.
This information does not answer the question. It explains how Covid-19 virus spreads and does not explain if the virus can live on mail or packages.

Am I at risk for COVID-19 from mail, packages, or products?
section_content: There is still a lot that is unknown about COVID-19 and how it spreads.
Coronaviruses are thought to be spread most often by respiratory droplets.
Although the virus can survive for a short period on some surfaces, it is
unlikely to be spread from domestic or international mail, products or
packaging. However, it may be possible that people can get COVID-19 by
touching a surface or object that has the virus on it and then touching their
own mouth, nose, or possibly their eyes, but this is not thought to be the
main way the virus spreads.

mail.

Reviewer feedback on this answer:
The answer addresses the risk of spreading the virus through packages and mail specifically.
This answers directly to the question. It provides information of whether or not virus can survive on surfaces including mail and packages and how people can catch the virus by touching the objects or surface.
