Nature (biology & culture) explains this Covid-19 & other pandemics. The “God” belief/faith explains nothing logical.
The dense populations in urban areas around the world plus travel plus some political stupidity explains a lot of the ability for the virus to spread & kill susceptible/unhealthy people.
Maybe Nature is telling us something.

Right and wrong. Yes, dense populations made it worse - so did travel - and politics did not help either.
The Bible prophecy in Revelation 6:5-8 is being fulfilled again - and this time the link between the kind of food shortage we now have and the deadly plague we now have is clear - e.g. a quart of wheat for a denarius (a denarius was a typical day's wage back then). i.e. if people have enough money, they can buy food. But unemployment (both for the employees and employers) has caused lower wages which is contributing to the current food shortage. Selfish hoarding doesn't help either,
All of this is consistent with Bible prophecy - so one interpretation of your post is wrong.
However, you need to clarify what you mean by "God belief." For example, the Bible says Satan is the ruler of this world, but many religions teach God is the ruler of this world and that everything is proceeding according to God's plan. The Bible is correct - many religions are wrong on this point,
Nature is also not primarily the cause of the Covid-19 pandemic - man is the primary cause. If anything supernatural is involved it would be from Satan not Jehovah.
