Carr to back up that assertion with a link or some facts you’ve got? Thanks.
Search "R naught" 3 times and put in a different disease name each search: covid-19, ebola, plague.
Make sure you limit searches to the last month. They have been revising the numbers upward on covid-19.

Just how contagious is the COVID-19 coronavirus? A new study suggests it may be much more contagious than initially thought.
Ohio Department of Health Director Dr. Amy Acton explained it using something called R0, or “R-naught,” which is a clinical term that calculates the spread rate of a disease.
The initial R0 for COVID-19 was 2.3.
“Whenever that R0 is above 1, it means we’re exponentially growing it,” Acton said.
As an example, Acton said an R0 of 2 means at first, there are 100 people infected, but in as little as three days, there could be 200 people infected, and three days after that, up to 400 infected, growing exponentially.
If the R0 is less than 1, cases become exponentially less – 100 people may spread it to only 50 people, then to only 25 people, Acton said.
“That’s when we start to see a disease burn out or we break those chains of transmission,” she said.
The new study from China and published on the CDC website suggests the R0 for COVID-19 could be as high as 5.7, meaning the disease is highly contagious. It is unclear if the new study refers only to cases in China or if it can be applied elsewhere.

Another factor in this is what's called asymptomatic transmission. You can spread covid-19 without having symptoms yet or even without ever getting sick from it. That's not true of the flu. With ebola, you need direct contact with bodily fluids, so it's just not as easily transmitted.
