Are chopsticks the "source of infection" of diseases? How do we use chopsticks healthily?

Chopsticks can be said to be a necessity that each of us can't live without every day. Are chopsticks the source of infection of diseases?

First of all, I think we need to know that many diseases are transmitted by hand and mouth, or saliva. And we use chopsticks every day, so chopsticks can spread some diseases, but not all diseases are spread through chopsticks.

Then how should we use chopsticks correctly? I think hygiene and disinfection are very important. Wash chopsticks in time after meals, and disinfect and replace chopsticks regularly. Here we need to pay attention to the use cycle of chopsticks, which can effectively avoid breeding bacteria. In addition, if conditions permit, we can have meals together, which can effectively avoid infecting some disease carriers. After all, eating a dish together can infect germs carried by others through chopsticks. Therefore, developing good personal dining habits can avoid bacterial infection.
