Infodemic – March 2020
March 2, 2020
Fear is the virus on which the news media thrives.
Viruses are with us everywhere and always. Illnesses defined under the umbrella of influenza kill between 10,000 and 50,000 Americans each and every year. Total annual deaths in the U.S. are about 2.8 million, so influenza makes up less than 2% of those deaths. Video of personnel in gowns and masks carrying sprayers invoke the fear response.
Past influenza epidemics include the 1957-58 Asian flu, the 1968 Hong Kong flu, and the 2009 Swine flu. The H1N1 Swine flu appeared in the United States first. There were estimated to be 60 million U.S. cases, but only 12,000 deaths. Worldwide, the Swine flu is estimated to have killed 200,000-500,000 people – 80% of those deaths were people under the age of 65.
So, what do we know so far about the current Coronavirus? Like most flu strains, it preys on the elderly and the infirm. So far, death rates have been significantly higher for those over 65, with the death rate increasing with age. Respiratory disease and diabetes also significantly increase the mortality rate. This is unlike the 2009 Swine flu in a good way, which preyed upon the younger and most productive. Most flu strains end up infecting a significant portion of the population. It is likely there have already been far more unconfirmed than confirmed cases, which would mean the actual mortality rate is far lower than the current published rate. The mortality rate for those who are healthy and younger is also significantly lower than the average.
There are a number of current responses that will probably help reduce the transmission rate and the mortality rate for this epidemic, at least among the developed countries. Hygiene is the most important, and more people will take precautions and wash their hands. The main human behavioral response is to reduce gatherings. That is also taking place. The medical community will sequence the genome of the virus, and this will enable some sort of vaccine to be developed. Warmer weather in the northern hemisphere may slow transmission, although this is yet to be seen. When the virus is identified earlier, it will allow the medical community to more aggressively treat those who have been infected, probably again lowering the mortality rate.
Fixed income investors have been the beneficiaries of the pain in the equity markets, as rates have fallen significantly. Corporate spreads have widened as equities have fallen, but lower Treasury rates across the yield curve have provided a tailwind to all fixed income. If markets do not stabilize soon, expect the Fed to react either with further comments or actions. Recent market volatility highlights the value that owning bonds within balanced portfolios can provide to long-term growth and stability.
We have had a sharp market correction in the last week, with most equity market indices declining over -10%. Corrections can happen for many reasons, and they are not terribly uncommon, although they have been less common during the current economic expansion. Will this outbreak reduce economic activity? Yes, but probably only temporarily. All virus outbreaks are serious and result in a tragic loss of life, but this virus outbreak may be more deadly than those that we have had in the past – only time will tell. One significant positive this time around is that it does not seem to attack the healthiest in our society as some past epidemics have. The markets seemed to show some signs of stabilization into the close last Friday, and we will continue to monitor events closely and adjust portfolios accordingly.

Random thought: The earth’s solar year is 365.24219 days long. Adding a day every 4 years moves us slowly ahead of the solar calendar. To adjust, we leave off a leap day every 100 years, but add it back every 400. 2000 was a leap year, the next century leap year is 2400.
