Coronavirus Update #70 GOOD NEWS: This information is so important to help us all understand risk. Stratified risk is the only true way to measure personal risk. Let us look at some CDC data from the spring Omicron BA.1 and .2 spikes versus the fall 2021 delta wave.
Median age of hospitalization has increased from 60 years old with Delta to 64 with BA.1 and 71 with BA.2. Any underlying medical condition associated with hospitalization increased from 89% with Delta to 92% with BA.1 to 95% with BA.2 respectively. Length of hospital stay decreased from 4.8 to 3.9 to 3.3 days. ICU admission was down from 24% to 18% to 13% of admitted patients. Mechanical ventilation decreased from 14% to 8% to 6% of admitted patients. And Finally, death from 12% to 8% to 5% overall.
What we can glean from this data set is very clear. With successive SARS2 mutations coupled to increased population based exposure to virus via infection or vaccine, we are now seriously in a reduced risk state unless you are older than 65 years with a comorbid disease or younger than 65 with a serious disease. 95% of hospitalizations were related to a comorbid disease regardless of age. The other big takeaway was this: if you are in this high risk group, getting every available booster is vital to your survival based on the risk reduction data. For everybody else, the data is clear, you are ok – to boost or not to boost is up to you. But, absolutely work on your general health.
To your health,
