Bill Gates In The New England Journal of Medicine: "... A Once-in-a-Century Pandemic?"

No. More to come.
But in a way we are fortunate that what we are faced with now is Covid-19 and not some mutant viral hemorrhagic fever or worse, a fully developed bio-terror weapon. An opportunity to learn and step up the response skills.
Nature really, really doesn't care if humans live or die and apparently a large subset of the population would actually prefer the latter.
En garde!

Responding to Covid-19 — A Once-in-a-Century Pandemic?

In any crisis, leaders have two equally important responsibilities: solve the immediate problem and keep it from happening again. The Covid-19 pandemic is a case in point. We need to save lives now while also improving the way we respond to outbreaks in general. The first point is more pressing, but the second has crucial long-term consequences.

The long-term challenge — improving our ability to respond to outbreaks — isn’t new. Global health experts have been saying for years that another pandemic whose speed and severity rivaled those of the 1918 influenza epidemic was a matter not of if but of when.¹ The Bill and Melinda Gates Foundation has committed substantial resources in recent years to helping the world prepare for such a scenario.

Now we also face an immediate crisis. In the past week, Covid-19 has started behaving a lot like the once-in-a-century pathogen we’ve been worried about. I hope it’s not that bad, but we should assume it will be until we know otherwise.

There are two reasons that Covid-19 is such a threat. First, it can kill healthy adults in addition to elderly people with existing health problems. The data so far suggest that the virus has a case fatality risk around 1%; this rate would make it many times more severe than typical seasonal influenza, putting it somewhere between the 1957 influenza pandemic (0.6%) and the 1918 influenza pandemic (2%).²

Second, Covid-19 is transmitted quite efficiently. The average infected person spreads the disease to two or three others — an exponential rate of increase. There is also strong evidence that it can be transmitted by people who are just mildly ill or even presymptomatic.³ That means Covid-19 will be much harder to contain than the Middle East respiratory syndrome or severe acute respiratory syndrome (SARS), which were spread much less efficiently and only by symptomatic people. In fact, Covid-19 has already caused 10 times as many cases as SARS in a quarter of the time.

National, state, and local governments and public health agencies can take steps over the next few weeks to slow the virus’s spread. For example, in addition to helping their own citizens respond, donor governments can help low- and middle-income countries (LMICs) prepare for this pandemic.⁴ Many LMIC health systems are already stretched thin, and a pathogen like the coronavirus can quickly overwhelm them. And poorer countries have little political or economic leverage, given wealthier countries’ natural desire to put their own people first.

By helping African and South Asian countries get ready now, we can save lives and slow the global circulation of the virus. (A substantial portion of the commitment Melinda and I recently made to help kickstart the global response to Covid-19 — which could total up to $100 million — is focused on LMICs.)....
