The CDC (Centers for Disease Control and Prevention) highlights that the coronaviruses commonly spread through air when infected people sneeze or cough, through close contact with an individual that is infected, and by touching a surface or an object that was exposed to this virus. Obviously, the last one also involves then touching your eyes, nose, or mouth.
Fortunately, experts all agree at the moment that the virus does not survive on packaging for a long time. This means that by the time what you bought or imported from China comes to your door, everything will be safe.
Patricia A. Stinchfield, National Foundation for Infectious Diseases (NFID) vice president, declared that the virus on materials ordered will not survive the trip. It is now believed that outside of the body, the virus just survives for minutes or hours, not days. Obviously, you still need to practice due diligence.
As an example, when you order a package from China to New Zealand, it can easily take 2 days for it to arrive, usually as a minimum. This practically means that import from China is 100% safe.
