Which of the following is NOT a method of virus transmission?

The method of virus transmission that is not typically recognized is solid food contamination. While certain viruses can be present on contaminated food, the transmission primarily occurs through other established routes such as droplet transmission, where respiratory droplets carrying the virus are expelled during coughing or sneezing, and can infect others who breathe them in.

Vector-borne transmission involves disease-carrying organisms, such as mosquitos or ticks, which can transmit viruses from one host to another, making it a recognized pathway for certain viral infections.

Surface contact refers to the transfer of viruses from surfaces to individuals, particularly when contaminated surfaces are touched and then the hands come into contact with the face. This form of transmission is significant in the spread of many viral infections.

In contrast, while food can become contaminated with pathogens, solid food itself is not a primary transmission method for viruses; more specifically, it's the surface and handling of food, as well as improper preparation or storage, that can lead to contamination and subsequently illness. Thus, solid food contamination does not align with the primary recognized methods of virus transmission like the others listed.
