Covid19 Update
Covid19 Update, April 27,2020
We are about four months into the appearance of this virus. Things are starting to slow down a bit. I caution you to not view the numbers as golf scores. We really don’t know how many people are infected despite the news people stating otherwise. The numbers they are referring to generally refer to the more serious cases that seek help and get a swab done. The true recovery rate is unknown, since it depends on knowing how many have the disease at the onset, something we simply make up or estimate. Currently, even though the greater Toronto area is the hotspot, our hospital resources are not overwhelmed.
Some interesting points that I have picked up by attending frontline medical rounds broadcasts from New York, Italy and London.
We will not need as many intubation machines as first thought. The doctors that give the best advice are those on the very front lines, and not those on the news. There are emergency doctors in New York and Italy that have had a great deal of experience dealing with the 2 percent of serious cases that newscasters sensationalize. They found ways to improve initial treatment and outcome. You may have heard that the need to intubate has greatly decreased. Doctors now recognize that the virus causes a inflammation in the chest. It is often not having any symptoms. Initially this finding along with measuring low oxygen blood values resulted in someone needing to be intubated. We can now use a very simple device called an oximeter to measure your blood oxygen and guide early treatment or even help with the diagnosis. We’ve also discovered that changing positions, which is what non sedated people normally do during sleep improves their oxygen transport and requires less intensive care.
As of yet we still have not received any personal protective equipment in the medical building adjacent to the hospital. This will create a significant problem in how to open up society after the lockdown, and start providing non emergency care. With the current data, the first assumption will be that everyone is susceptible, except those that had a positive test. In fact, if you look at the textbooks, they suggest that many had and fought the virus without knowing it. The numbers will drop, they always do. We will probably use this tid bit to confirm that lock-downs work, without any good evidence to support. The danger to the economy is that if we adopt this way of life, and lock down during flu seasons,and subsequent respiratory outbreaks, our way of life will change with a great deal of more poverty.
The vaccine is a long way off. The coronavirus is a common cold virus that we see a lot of, with more severe strains causing SARS and MERS. Interestingly, work began on vaccine production 15 years ago. Bill Gates gave a Ted talk on YouTube in 2015. It is short and sweet but almost predicts this pandemic to the fine detail. The best vaccines worked really well and were developed 60 years ago: polio, tetanus, smallpox, diptheria, measles, mumps and rubella. The other ones tend to not work as well and need repeating such as the annual flu-shot. It make sense that coronavirus vaccine will fall into this less effective class.
In the medical world, we are seriously questioning the numbers coming from China. They are deftly misleading and under calculated. Unfortunately, this creates a legal – political problem more than a medical one. I hope the ramifications from the economic meltdown will not affect us too seriously. There is a tremendous back log of regular work that needs to be done in the medical system that this has created. Even when reopened, the system works close to its maximum so the ability to take up any slack will produce backups and slowdowns for months if not years.
Be safe be healthy
