What is the risk that the courier can still test positive after half a month?

There is no risk in such express delivery.

This is mainly because COVID-19 cannot survive in a dry and warm environment for a long time. Even if COVID-19 can be detected on the courier, it doesn't necessarily mean that COVID-19 is still active. Many viruses are actually dead viruses. COVID-19 positive was detected on the courier, which only proved that the courier was contaminated.

First, the courier can detect COVID-19 positive within half a month after receiving it.

When everyone saw this news, many people said that they were afraid to accept express delivery, because even though a courier had been sent for half a month, the courier could still detect COVID-19's positive. In this case, the expert gave a scientific conclusion, and said that the fact that the express parcel was positive for COVID-19 did not mean that the express parcel was contagious.

Second, the risk of express parcel delivery is actually not that great.

According to experts, because COVID-19 can't survive on the surface of the courier, it means that COVID-19 on the courier is likely to have died, and it is not contagious at this time. The reason why the courier can detect COVID-19 positive is only because the courier is polluted by COVID-19, but this does not mean that the courier is contagious and users need not worry too much.

Third, users need to do a good job in prevention and control of COVID-19 in advance.

Although it is difficult for COVID-19 to survive in the express delivery industry, as users themselves, users still need to do a good job in the prevention and control of COVID-19. Users must wash their hands frequently when receiving express delivery, and try not to touch express parcels that have nothing to do with them. Because there are sporadic confirmed cases in some cities in COVID-19, it is necessary to strengthen the awareness of prevention in COVID-19, and it is best not to gather in places with too many people. To some extent, COVID-19 is easier to survive for a long time in winter, so users must learn to protect themselves and the people around them.
