In the OT, especially in Leviticus, God makes very clear commands for what to do when there is an infectious disease. It's clear that He is for fighting it in any way possible, even to putting people out of the camp until they are healed. One verse says that even after they come back into the camp they must remain outside their tent for another seven days. He was more concerned with not spreading disease than people meeting together with other worshippers.
Our faith and the church isn't so weak that we can't hold it together for another few months unless we have so little faith in God that He won't hold us up and cause us to stand even though He says He will.
Leviticus 14:8
The one being cleansed must wash his clothes, shave off all his hair, and bathe with water; then he will be clean. Afterward, he may enter the camp, but he must remain outside his tent for seven days.
This was for skin disease, what might He say about an airborne disease, a disease that can be spread from people with no symptoms at all?
I believe from what I read in the Bible is that God would want us to do what is prudent and adhere to 'best practices' to not infect others.
