Cause 1: Coronavirus is very sensitive to heat. It is difficult to survive at higher temperatures. The temperature of the food we eat is relatively high in most cases. Even if the food producer slightly pollutes the food in the production process, it is difficult for the virus to remain active in this case.
Reason 2: Coronavirus needs a certain amount to cause disease. If the number of invading viruses is too small, it will be directly eliminated in the immune system. Even if there is a virus on the surface of the packaging box and food, it is difficult for us to achieve the minimum amount of infection and cause disease when eating takeaway.
The main route of transmission in novel coronavirus is droplet transmission. If people who make food are infected and there are no protective measures in the production process, it is easy to spread the virus into food. If the takeaway is infected, it is also likely to leave a virus on the packaging bag.
