There is a surprising number of evangelist church groups that have been actively spread ing COVID19 because they refuse to wear masks, take vaccines, social distance &c. Those people are literally a plague on society. Many of them claim that old people and others listed as dying of COVID19 actually die of other problems, and that the pastor of the Church is the ONLY one to believe regarding the history and treatment of viruses. Regarding New and Old Testaments:

In the New Testament, Jesus healed “every disease and every sickness,” as well as plagues in the areas He visited (Matthew 9:35; 10:1; Mark 3:10). Just as God chose to use plagues and disease to show His power to the Israelites, Jesus healed as an exhibition of the same power to verify that He was truly the Son of God. He gave the same healing power to the disciples to verify their ministry (Luke 9:1). God still allows sickness for His own purposes, but sometimes disease, even worldwide pandemics, are simply the result of living in a fallen world. There is no way to determine whether or not a pandemic has a specific spiritual cause, but we do know that God has sovereign control over all things (Romans 11:36) and will work all things together for the good of those who know and love Him (Romans 8:28). source
