With all due respect, I think 99+% of people who Google “coronavirus” are looking for info about Covid-19, and as such the results being about C19 is pretty reasonable imo. It’s like how if you Google “watergate” you’ll near-exclusively get stuff about the watergate scandal (because that’s what most people who search “watergate” are looking for), and not about booking at the watergate hotel or other amenities of the watergate complex.
