Agree -
Relevant information not being discussed - fatality rates for Mers (30 per cent) and Sars (10 per cent) - this puts things in perspective since C****-** is running around 2 percent...
Enough of the sensationalism - all it does is fuel the scare tactics...
I agree with the figures you cited above. But comparing one mere aspect of diseases is too simplistic. Also, the case fatality rate you mentioned for C****-** is based on the ongoing data. Remember, the disease is still ongoing and evolving and CFR (case fatality rate) you mentioned may change.
Not trying to stir up fear or panic when I posted the above subject. My main goal is to inform. I believe one of the reasons why c****av***s is getting all the attention and not the flu (not implying the flu is not important) is because we still don't know a lot about this C****-**. It is nothing to sneeze at.
One big difference between the flu and the C****-** is the rate of t***smission or Ro (R-nought or R- zero). The flu has an Ro of 1.3 whereas C****-** is between 1.5-3.5 (in preliminary studies; WHO suggests 1.4 to 2.5). One person infected with the flu will t***smit it to 1.3 people while C****-** 1 infected person will t***smit it to 1.5 to 3.5 people. If you do the math, you'll see the big difference.
Another difference is the incubation period: Flu incubation period is between 1 to 4 days whereas C****-** can be as long as 14 days (WHO and CDC) or as long as 19 days (JAMA), or as long as 24 days (one Chinese study) or as long as 27 days (another study), depending on who you believe. Both flu and C****-** can t***smit the disease before symptoms happen (asymptomatic), with much longer incubation period an infected but asymptomatic person can spread C****-** much longer than the flu without even knowing it.
Another difference, based on available data and cases, it appears the severity of the following v***ses from the least severe to the most is as follows:
Flu < C****-** < SARS < MERS (C****-** is more severe than flu but less severe than SARS and MERS).
Another difference between flu and C****-** is, there is available v*****e for the flu (although based on what strain most likely for the season) and anti-v***l medications while nothing for C****-** at the present.
In sum,
1) We know more about the flu than the C****-** at the present time. Wouldn't you rather face an enemy you know a lot than one you know very little?
2) Based on available data, C****-** symptoms are more severe than flu.
3) There are available v*****es and anti-v***ls against the flu but none for C****-** at present. Wouldn't you rather go to war against an enemy with guns and bullets rather than just with your bare hands?
Here's a couple of recent articles explaining why C****-** is not just your common, ordinary flu.

How Does the C****av***s Compare With the Flu? Feb. 29, 2020
https://www.nytimes.com/2020/02/29/health/c****av***s-flu.html As new cases appear on the West Coast, some — including the president — are comparing it to the seasonal flu. Here’s a close look at the differences.
Is this new c****av***s really a serious danger? Doesn’t the flu k**l more people?
As the United States recorded its first c****av***s death on Saturday — and as other cases popped up in people without known risks on the West Coast — Americans wondered how to measure this new threat against a more familiar foe: influenza.
President Trump, a self-described germophobe, said on Wednesday he was amazed to learn that tens of thousands of Americans died from the flu each year, contrasting that number with the 60 or so known to be infected with the c****av***s. On Friday, Mr. Trump accused the news media and Democrats of exaggerating the dangers of the v***s.
“The flu k**ls people,” Mick Mulvaney, the acting White House chief of staff, said on Wednesday. “This is not Ebola. It’s not SARS, it’s not MERS. It’s not a death sentence.”
To many public health officials, that argument misses the point.
Yes, the flu is terrible — that’s exactly why scientists don’t want another contagious respiratory disease to take root. If they could stop the seasonal flu, they would. But there may yet be a chance to stop the c****av***s.
In many ways, the flu is the best argument for throwing everything at the c****av***s. Here’s a closer look at the similarities and differences.
Which v***s is deadlier?
The c****av***s seems to be more deadly than the flu — so far.
On average, seasonal flu strains k**l about 0.1 percent of people who become infected. The 1918 flu had an unusually high fatality rate, around 2 percent. Because it was so contagious, that flu k**led tens of millions of people.
Early estimates of the c****av***s death rate from W***n, China, the epicenter of the outbreak, have been around 2 percent. But a new report on 1,099 cases from many parts of China, published on Friday in The New England Journal of Medicine, finds a lower rate: 1.4 percent.
The c****av***s death rate may be even lower, if — as most experts suspect — there are many mild or symptom-free cases that have not been detected.
The true death rate could turn out to be similar to that of a severe seasonal flu, below 1 percent, according to an editorial published in the journal by Dr. Anthony S. F***i and Dr. H. Clifford Lane, of the National Institute of Allergy and Infectious Diseases, and Dr. Robert R. Redfield, director of the Centers for Disease Control and Prevention.
But even a disease with a relatively low death rate can take a huge toll if enormous numbers of people catch it. As of Sunday, there were about 87,000 c****av***s cases and 3,000 deaths. This week, for the first time, the number of new cases outside China exceeded the number within the country.
Which v***s is more contagious?
So far, the new c****av***s seems to be more contagious than most strains of the flu, and roughly as contagious as strains that appear in p******c flu seasons.
Each person with the c****av***s appears to infect 2.2 other people, on average. But the figure is skewed by the fact that the epidemic was not managed well in the beginning, and infections soared in W***n and the surrounding province. As an epidemic comes under control, the reproduction number, as it’s called, will fall.
By comparison, the figure for the seasonal flu is roughly 1.3. The reproduction number for the flu of 1918 was about the same as that of the new c****av***s, perhaps higher, but that was before modern treatments and v*****es were available.
In both flu and the illness caused by the c****av***s, people may be contagious before symptoms develop, making it difficult or even impossible to control the spread of the v***s. Nobody knows how many people infected with the c****av***s have only very mild symptoms or none at all.
Who is most at risk from infection?
Both the c****av***s and influenza are most dangerous to people who are older than 65, or have chronic illnesses or a weak i****e s****m.
Death rates among men infected with the c****av***s in China, particularly those in their late 40s and older, have exceeded those among women, a pattern not seen in the seasonal flu. The reason for the discrepancy is not known, although Chinese men do smoke more, often resulting in c*********d lung function.
There seems to be another important difference: The flu appears far more dangerous to children, particularly very young ones, who can become severely ill. Children infected with the new c****av***s tend to have mild or no symptoms.
The flu is also especially dangerous for pregnant women, who can become severely ill from it. Whether the new c****av***s poses as serious a threat to pregnant women is not known.
Which v***s makes you sicker?
As of Feb. 22, in the current season there were at least 32 million cases of flu in the United States, 310,000 hospitalizations and 18,000 flu deaths, according to the C.D.C. Hospitalization rates among children and young adults this year have been unusually high.
There would be even more illnesses and deaths if there were no flu v*****e. Most people recover in less than two weeks, and sometimes in just days.
By contrast, about 70 people in the United States have been infected with the new c****av***s, and there has been one death. There are no treatments or v*****es for the c****av***s, only supportive care for infected people.
Most cases of c****av***s infection are not severe, but some people do become quite sick. Data from the largest study of patients to date, conducted in China, suggests that of c****av***s patients receiving medical attention, 80 percent had mild infections, about 15 percent had severe illnesses, and 5 percent were critical.
The first symptoms, fever and cough, are similar to that of the flu, so the diseases can be hard to tell apart without a test to identify the v***s. Pneumonia is common among c****av***s patients, even among those whose cases are not severe.
Experts think there may also be many people with no symptoms at all, or such mild ones that they never bother to seek medical attention. Because those cases have not been counted, it’s not possible now to know the real proportion of mild versus severe cases.
Antibody tests, which can determine whether someone has ever been infected, may eventually help to establish how many people had mild or asymptomatic c****av***s infections.
Can people become immune to the c****av***s?
After v***l infections, people generally develop antibodies in their blood that will fight off the v***s and protect them from contracting it again. It’s reasonable to assume that people who have had the new c****av***s will become immune to it.
But it is not known how long that immunity will last. With other c****av***ses, which cause the common cold, immunity can wane.
There are v*****es for the seasonal flu, of course, and these induce at least partial immunity to influenza.
What treatments are available?
There is no approved antiv***l drug for the c****av***s, though several are being tested. Doctors can recommend only the usual remedies for any v***l illness: rest, medicine to reduce pain and fever, and fluids to avoid dehydration.
C****av***s patients with pneumonia may also need oxygen, and a ventilator if breathing trouble worsens.
For the flu, however, there are four prescription medicines. All work best if they are taken within a day or two of when symptoms start.
They’re not miracle cures: They can lessen the severity of the illness and shorten its course by a day or so, and they may lower the risk of serious complications.
The drugs are also recommended for people who have been exposed to a flu patient, to try to prevent the illness.
The flu, like the c****av***s illness, can also cause pneumonia and breathing trouble. Anyone who becomes short of breath needs medical attention quickly.
Can I get v******ted?
An experimental v*****e for the c****av***s may be ready for testing in humans within a few months, but will take much longer, at least a year or two, to become available for widespread use.
Flu v*****es, on the other hand, are widely available and generally 40 percent to 60 percent effective, which means they will reduce cases by that amount in a population that has been v******ted, compared with one that has not.
The v*****e for the current season falls into that range, according to the C.D.C., which said on Feb. 21 that people who have not been v******ted should still get the shot, because the flu season is ongoing.
Experts have been urging people to get the flu shot for all the usual reasons. But now there’s another: If there is a c****av***s outbreak in the United States, hospitals will need all the beds, equipment and staff they can muster.
It will be important not to have those resources taken up by patients with flu that could have been prevented.
Will the c****av***s go away when the weather warms?
Mr. Trump has said repeatedly that the c****av***s will retreat as weather warms, just as influenza does. In fact, because this is a new v***s, there is no information about how the weather might affect it.
Even if the v***s were to diminish in the spring, it might rebound later in the fall, as the weather cools. This is a pattern often seen in severe flu seasons.
Containment is becoming less likely, because of the contagiousness of the v***s, the possibility that people can spread it before they have symptoms and the increasing number of outbreaks around the world.
The cases in California, Oregon and Washington State without known links to overseas travel, reported on Friday, may be a warning sign that the new c****av***s has already begun to circulate.
Yes, it is worse than the flu: busting the c****av***s myths
https://www.theguardian.com/world/2020/mar/01/yes-it-is-worse-than-the-flu-busting-the-c****av***s-mythsClaim: ‘It is no more dangerous than winter flu’
Many individuals who get c****av***s will experience nothing worse than seasonal flu symptoms, but the overall profile of the disease, including its mortality rate, looks more serious. At the start of an outbreak the apparent mortality rate can be an overestimate if a lot of mild cases are being missed. But this week, a WHO expert suggested that this has not been the case with C****-**. Bruce Aylward, who led an international mission to China to learn about the v***s and the country’s response, said the evidence did not suggest that we were only seeing the tip of the iceberg. If borne out by further testing, this could mean that current estimates of a roughly 1% fatality rate are accurate. This would make C****-** about 10 times more deadly than seasonal flu, which is estimated to k**l between 290,000 and 650,000 people a year globally.
Finally, it is not sensationalism as you claimed. Just the facts, m'am. Just the facts.
