I’ve been studying the research on Covid-19 since February, and I’ve read through hundreds of studies. I follow various physicians with YouTube channels specifically on Covid. And I’ve come to a conclusion: Covid-19 is seasonal. It is like the human coronaviruses that cause colds, in which the number of cases in winter is much higher than in summer. And this means that the number of Covid-19 cases in the U.S. in winter will be much higher than July. But July had nearly 2.0 million cases. Also, the death rate will be higher, not just as a higher number due to the higher case rate, but the percentage itself will also be higher.

Hypothetical example:
July, 2 million cases, death rate 1.35% = 27,000 deaths (actual number 26,703)
If the case rate increases by 50% in November:
Nov. 3 million cases…
death rate 1.35% — 40,500 deaths
death rate 4% — 120,000 deaths
death rate 6.6% — 198,000 deaths

So if the death rate states the same, but the number of cases goes up by 50%, then the number of deaths goes up by 50%. But if the death rate itself also increases, the number of cases is very much higher, as you can see in the above example.

By February, we could see a death rate of 6.6% or more, and a monthly number of cases several times the July rate of 2 million. As a result, monthly deaths could be as high as 0.5 to 1.0 million deaths in the U.S. alone in February alone. The worse months for seasonal illnesses tend to be Jan., Feb., March. It’s difficult to say which of those three will be the peak.

What causes this increase? Vitamin D levels in the blood. People are outside more in summer. Sunshine on skin makes vitamin D in the blood.

A high intake of vitamin D reduces risk of stroke [28], multiple sclerosis [29], rheumatoid arthritis [30], type 2 diabetes [31], breast cancer [32], prostate cancer [33], colon cancer [34], and all-cause mortality [35].

And 18 studies [1-18] show that vitamin D reduces Covid-19 risk, specifically, the risks of: infection [7, 8, 9, 11, 12, 14, 16], a severe case [1, 3, 4, 5, 15, 17], hospitalization and/or ICU care and/or ventilation [2, 10, 14, 15], and death [4, 6, 7, 9, 12, 13, 17, 18].

Winter 2020-2021

The U.S. had just under 2.0 million cases this past July. If Covid-19 is seasonal, the cases per month this winter will be a multiple of 2 million. And the death rate will not be the 1.35% of July, but more likely the 6.6% death rate of April. The number of deaths each month this winter could exceed 500,000 and could reach as high has 1 million. Those figures are total deaths per month, just in the U.S., against a case rate of several million to possibly over 10 or 15 million cases per month.

The U.S. healthcare system cannot handle that many cases. THE SYSTEM WILL BREAK. And then the death rate could go as high as 10, 15, or 20% of total cases. A typical death rate for hospitalized cases is 24%. Some of the better hospitals, those using the MATH+ Protocol, have death rates from 3.3% to 6.1% for hospitalized cases (that’s low!). But if the system breaks, many people will receive no care at all. If they can’t breathe, they will suffocate to death in their own homes, as there won’t be hospital equipment, beds, staff to treat them.

The SECOND WAVE is coming. The research proves it. Covid-19 is a vitamin D responsive illness. But vitamin D levels are much lower in winter than in spring:


We can AVERT the Second Wave with a massive vitamin D “supplementation and sunshine program”. It takes a month of high-dose vitamin D supplementation to raise vitamin D blood levels to the required point (over 40 ng/ml which is over 100 nmol/L).

We also need to do what Turkey did — build large 1,000 plus bed hospitals in 45 days: News.Sky.com and MiddleEastEye.com. Wikipedia: Dr. Oz Hospital and Dr. Murat Hospital.

The problem, of course, is that the U.S. does not have enough hospital beds. According to Statistica, the U.S. had 924,107 hospital beds in 2018. But hospitals typically run very close to capacity. It is not economical to maintain enough “beds” for a large surge of patients. By the way, the term “hospital beds” does not only mean physical beds, but the equipment and staff needed to serve the patients in those beds. So a pandemic can easily overwhelm the hospital system.

The Second Wave could seed 5 to 10 to 15 million new cases of Covid-19 per month this winter. The system cannot handle that many patients. Now 80% of those patients are mild or moderate, patients who might be treated at home. But 20% of 5 million is 1 million hospitalized Covid-19 patients, and we don’t have the beds. Even if we kick out of the hospital all other patients, we don’t have a million beds. Then at 10 or 15 million cases, the hospitalized number is 2 to 3 million in-patients. That’s two to three times the total number of hospital beds.

We should be building hospitals as Turkey did in under 60 days. But that’s only 1,000 beds per hospital. You just can’t build 1 to 3 thousand new hospitals — even if we had the money and the construction equipment, you couldn’t find enough hospital equipment to equip those new hospitals, and we don’t have enough doctors and nurses.

So the ONLY approach that will work is prevention. And there are few proven means to prevent Covid-19 or to prevent a severe case of Covid-19 or to prevent death from Covid-19. The most proven method is vitamin D supplementation. There is a study on hydroxychloroquine as a prophylactic [19]. Ivermectin was used as a prophylactic against scabies, and they inadvertently discovered that it worked against Covid-19 as a prophylactic as well [20]. Some persons take quercetin and zinc as a prophylactic, but there’s no clinical studies supporting that use. So vitamin D is our best prophylactic, at this point in time.

Now the FDA will tell you that vitamin D and other supplements or medications are not formally proven to prevent Covid-19 nor to decrease risk of a severe case or risk of death from Covid-19. But you go to war with the information you have, not the information you wish you had.
