Does more exposure to a virus make you sicker?

A few months ago, there was a meme about how all of the COVID virus in the world would be able to fit into a tablespoon, and the meme was about someone eating it (very silly, yes). But that got me thinking about what would happen if that was possible. Does more exposure to a virus cause you to get sicker, or would the immune response be the same? Maybe as a side question, would the person from the meme (assuming they were healthy and wouldn't have died from COVID normally) have died from that much exposure?

The measure of how many viral particles are either circulating or you are otherwise exposed to is called "viral load" or similarly "infectious dose." Speaking very generally, our bodies do pretty well fighting off infection when viral load is small, as those few particles would have to successfully reproduce, and there would be simply more time available for the immune system to catch up. If your viral load is higher, then the infection can begin to rapidly spread throughout the body before the immune system had a chance to stop it. 

With respiratory viruses like COVID19 the infectious dose correlates with how sick you get.

There are, however, a ton of variables to this.
