COVID-19 Associated Stroke--A Single Centre Experience
doi: https://doi.org/10.1101/2021.02.15.21249420
In this single hospital review of patients the authors reported “62 stroke cases among 3923 COVID-19 admissions (incidence 1.6%)”.
From personal experience helping a friend I can tell you “covid brain fog” is bad enough but adding a stroke on top is another level of bad.

Copy And Paste From Johns Hopkins
EMERGING VARIANTS A study published (preprint) by Harvard University examines the nasopharyngeal viral concentration in individuals infected with the B.1.1.7 SARS-CoV-2 variant. The researchers performed a series of PCR-based diagnostic tests over a series of weeks to evaluate temporal dynamics of the viral concentration for this variant of concern. The study included 65 total participants, including 7 infected with the B.1.1.7 variant. The researchers found that infection with the B.1.1.7 variant lasted significantly longer than for other variants, with a mean duration of infection of 13.3 days for the B.1.1.7 variant, compared to 8.2 days for non-B.1.1.7 variants. While the duration of infection was longer for the B.1.1.7 variant, the peak viral concentration was similar between B.1.1.7 and non-B.1.1.7 variants.
Even though the peak nasopharyngeal viral concentration is similar between the B.1.1.7 and non-B.1.1.7 variants, the longer duration of infection could potentially be a factor in the variant’s increased transmissibility. If individuals infected with the B.1.1.7 variant take longer to clear the virus from their system, their infectious period could potentially be longer as well, which could result in additional exposures compared to non-B.1.1.7 variants. Further investigation is necessary to better characterize the drivers of the increased transmissibility, but this study provides insight into potential mechanisms that contribute to the variant’s ability to spread more rapidly in the community.

Over 50% of us population has had Covid-19 ('natural immunity')???
The CDC is estimating that at the end of 2020 the Covid-19 disease burden (total number of people infected) was 81.3M; that is about 25% of the US population. I doubt there was a doubling of infections between the end of 2020 and now.

Your data is almost two months old. The 70% drop in cases is only explained by the +10% who have received the vaccine plus the folks who have had the virus.

Assuming the 83.1M estimated infections were based upon 20.5M reported cases (this is aligns with previous studies indicating only 25% of the total infections are detected by the current PCR testing rates); then 28.5M reported cases would equate to 115.5M estimated infections or 35% of the US population.
If one counts the estimated 11.2M fully vaccinated people, then the percentage of the population with immunity increases to 38%.

Only explained, probably not.
Infected and vaccinated individuals probably have had some effect, but also the holiday gatherings of Thanksgiving, Christmas, New Years being over along with more people getting with the public health programs of mask wearing, social distancing, etc. have probably had an effect as well.

Hi BradW,
How about getting numbers from a more reliable source than Fox?
Such as John Hopkins?

Whoopy ding. Canada has vaccinated 1 million persons. That works out to a lousey 2.6% I guess it is better than nothing.
Exactly 0 injections made in Saskatchewan in the last 72 hours.
Scientists do not yet know what proportion of the population needs to be vaccinated to achieve herd immunity. But if that threshold was 70% (like the flu), 51,824,532 doses would still have to be injected in Canada.

If you had bothered to click on the second link I posted and take a look at the first chart showing the sharp 70% decrease in cases (250k/day down to 72k/day), you would have noticed the data are not Fox data, they are from John Hopkins......as you requested. ![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile")

Its very good news......be happy.
