the question is not which one is current--DUHif it kills more people faster than it kills itself faster = not as deadly as the common fluwrongAnd yet COVID-19 has killed many more than SARS did in 2003. How can that be? Oh, right, it's infected many more people.
Yes, there's a lot more panic than necessary about coronavirus. However, the deadliness of a disease is not limited to the percentage of people who get it that die. It also has to do with how many people get it. The Spanish Flu is estimated to have killed at least 50 million people. It had a lower death rate than MERS, though. Still, it was one of the deadliest infections to occur in human history. That's because it is estimated to have infected 500 million people.
dead·ly
/ˈdedlē/
adjective
Spanish Flu comparison is wrong---that was over a hundred years ago
- causing or able to cause death.
Something is able to cause more death if it affects more people. Only 8,000 people got MERS. It was deadly within that group, but not to the overall population.
Okay, you REALLY need Captain Obvious to state himself?
Out of those viruses in your OP .................... which one is current?
Take your time.
Then we're back to the original and still-unanswered question ---- what's the point?
