It makes it more lethal ...
About 36% of those diagnosed with MERS died, however, only 2,000 cases were ever reported. They added the following caveat: The overall risk of death may be lower as those with mild symptoms may be undiagnosed. Same may be in play here. Because so much is unknown we can not state with certainty that it is deadlier. Just that of the known reported cases the percentage of deaths is a little higher.
So far in the U.S. alone, the flu death toll is about 18,000, which is significantly higher than the death toll so far from the coronavirus.
So in reality this is nothing more than wild speculation. While the claim is true, when you examine the claim you begin to see the hype, and the realization that the numbers could very easily, and most likely does, represent an incomplete picture.
But by all means, run out in a panic and buy up all the bottled water you fear you may need. Or you can calm down and start looking at it employing more critical thinking.
At this point it time there has been minimal threat to residents of the U.S. Even throughout the entire world at this point the impact has not been that bad. Last time I looked there were about 90,000 cases worldwide, the majority in China itself, that have resulted in 3,000 deaths.
In comparison 32,000 deaths occur in the U.S. from auto accidents. Has that caused you to stop driving, or even cause you concern about continuing to drive?
