According to the DHS (I’m struggling to find a source that isn’t the White House slides, which I loath to link too) COVID-19 has a half life of about 2 minutes in sunlight on a warm day (21C).

So we’re safe from lingering viruses because COVID-19 doesn’t linger that long outside.

As viruses go COVID-19 is pretty easy to break down, and doesn’t last that long in the wild (especially compared to things like bacteria). But it’s still virulent enough to cause a pandemic, despite being pretty easy to destroy using light and alcohol.
