Informative Read: The Swine Flu And Me
That's the title of a blog by William Jacobson at Legal Insurrection . He points out a number of things that should give pause to anyone who think that Covid-19 isn't a big deal, or that the Swine Flu wasn't a big deal. Of particular interest to me is the epidemiological data--young v. old. It would be mistaken at this point to assume that we truly have a handle on what could happen:
Two things are true at the same time: Wuhan Coronavirus should be taken seriously as a public health danger, and Democrats and the media are trying to weaponize it for election purposes.

In September 2009, I caught Swine Flu during the semester when I was at Cornell in Ithaca. It was brutal.
For the first time I understood how the flu could kill someone.
It went straight for my lungs. It felt like someone parked a truck on my chest, and I had high fever. I was lucky to be able to get to a doctor before it became really bad and was given Tamiflu and the types of inhalers people with asthma use to keep my lungs open. I needed refills on the inhalers, and I’m convinced they kept me alive.

The Swine Flu statistics were staggering, according to this CDC publication:
The (H1N1)pdm09 virus was very different from H1N1 viruses that were circulating at the time of the pandemic. Few young people had any existing immunity (as detected by antibody response) to the (H1N1)pdm09 virus, but nearly one-third of people over 60 years old had antibodies against this virus, likely from exposure to an older H1N1 virus earlier in their lives. Since the (H1N1)pdm09 virus was very different from circulating H1N1 viruses, vaccination with seasonal flu vaccines offered little cross-protection against (H1N1)pdm09 virus infection. While a monovalent (H1N1)pdm09 vaccine was produced, it was not available in large quantities until late November—after the peak of illness during the second wave had come and gone in the United States. From April 12, 2009 to April 10, 2010, CDC estimated there were 60.8 million cases (range: 43.3-89.3 million), 274,304 hospitalizations (range: 195,086-402,719), and 12,469 deaths (range: 8868-18,306) in the United States due to the (H1N1)pdm09 virus.
Bear in mind: As far as we know, nobody has any immunity whatsoever to Covid-19. That's especially important to consider given the novel way in which this coronavirus is transmitted--i.e., it has a novel type of 'envelope' that more closely resembles AIDS than other coronaviruses like SARS. That alone justifies the high levels of concern.
