“In graduate school, I worked with a virus that infects bacterial cells (bacteriophage T1). One T1 virus particle takes about 10-12 minutes to break open the E. coli cell and release over 100 new virus particles. Each new particle can infect a cell and produce over a hundred new virus particles. So, 10-12 minutes later, there are 10,000 viruses. I could do some experiments in the morning and have the results that afternoon.

To make stocks of the virus, we would infect a late culture of bacteria. A couple of hours later, all the bacterial cells were broken open, leaving only virus.

Coronavirus

 

 

 

Animal viruses, like coronavirus, probably take hours to reproduce, but each infected cell produces at least a thousand new virus particles.

Consequently, I have a healthy respect for viruses.”
