What’s now clear about the coronavirus epidemic

There is still a good deal that is unclear about the CORVID-19 epidemic, but a few things have become clear:

1.  It is clearly more dangerous than the seasonal influenza. Seasonal influenza kills about 0.1% (1 in 1000) of those it infects. CORVID-19 looks like it is lethal in about 1-2% of cases (1 in 100 or 1 in 50).  And for the old the percentage of deaths is significantly higher, running about 15% (1 in 7) for those 80+. 

2. We have no idea how widespread the infection is in the US, because we have tested so few people. We know the number who are ill enough to get hospitalized and tested, where test kits were available, but that is so few cases thus far that we are really running blind at the moment.  It is highly likely that we already have hundreds or even thousands of people in the U.S. with mild or no symptoms, spreading the infection.

3. The official response in the US has been, to put it charitably, pathetic. At the point where South Korea had tested 140,000 people, the US had tested about 2000, and the fiasco with the production of testing kits is just the tip of the iceberg. Trump can’t figure out what to do. He is trying to limit panic, but he is so clumsy at it that the result is simply confusion. But the incompetence isn’t just limited to the president; the whole federal bureaucracy and political system can’t get its act together or move fast enough or decisively enough to make any difference.

4. It is clear that this infection will sweep through a majority of the U.S. population within the coming months, no doubt causing - belatedly - school and business closing throughout the economy and disrupting life for all of us. Fortunately, most people will only get the mild version, often no worse than a cold, but there will be a significant number of deaths and a good deal of panic and hoarding.  (Why people are stocking up on toilet paper, of all things, is beyond me. Toilet paper is made in the U.S., from trees grown in the U.S. – we aren’t going to run out of it, unless of course the hoarders get it all.)

5. It is also clear that this epidemic is going to cause a severe economic hit to the entire world. The U.S. will probably be impacted less than most other countries, but even we will feel pain. The problem is that key supply chains throughout the world have been cut off. A new car or a pharmaceutical product may only have 5% of its components sourced from, say, China or Italy or South Korea, but if that 5% disappears, one can’t complete and deliver the car or the medicine. This is true of hundreds of thousands of products we buy or use daily, and we are about to see how dangerously interdependent and vulnerable the world economy has become.

6. The worst of the pain will be probably be delayed until April or May. Companies know that Chinese factories close down for the Lunar New Year, so they build up inventory in anticipation, In addition, it takes about 30 days to ship goods from Asia to the US by sea, so we have a 30-day supply still in transit. Once that excess inventory is used up and the goods at sea arrive and are used up, the pinch will start.

7. Our best hope is that state and local governments are more competent than the federal government, and move decisively to limit the infection and the economic dislocation. State and local governments are closer to the people they govern, and therefore tend to be more responsive than federal officials and politicians – not always true, but true more often than not.
