Viral infections are usually related to the virus first invading the cell and then replicating there. This whole thing takes time as the virus first needs to pass through the physical barriers and then replicate and produce toxins which cause the symptoms.

Doesn't sound right, do you have a source? Most early symptoms (especially those OP mentioned) are related to the immune response and the immune response could be triggered before the virus even enters cells, or more likely sometime after when the virus has replicated to high enough levels to trigger a sufficient response. In any case, it certainly should take days for the first viral particle to enter and replicate for the very first time.

Do you have a reference for your assertion that “viruses produce toxins”?
