Many studies of early, outpatient treatment ie within 5 days of onset of symptoms have shown benefit of combinations of hydroxychloroquine with zinc and either azithromycin or doxycycline

Likewise, most viral diseases respond to antiviral drugs only in early stages eg influenza to oseltamivir or herpes to valacyclovir

Thank you so much for engaging in this work. Desegregated data is so difficult to find in many sub-populations. It would be interesting (although there is likely limited or no funding resources for this) to see this data in a table alongside of other respiratory illnesses. My other wonder is in the evaluation of whether or not to have my daughter participate in the vaccine at this point. We have typically had her take the flu shot, but given the elevated adverse responses the vaccines have had when compared to the flu, it would be helpful to have a resource by which we can evaluate our decision.

Looks to me that colchicine shows more benefit on men than on women. Probably this is because men are more likely to be smokers or have preconditions such as diabetes and hypertension. If excluding the data of the women patients, I assume the study would show a better stat significance among the male population with mild preconditions. This is worth further exploring. With this data, I may consider limited using colchicine only for those male Covid patients with mild preconditions. Overall, I think this study is constructive but a little bit disappointing, to be honest.

Good job, team, but you shouldn't have stopped at 75% recruitment in favour of quick results. A delayed but robust conclusion is much better than a hasty and uncertain one.

By only analysing data from vaccine recipients you have demonstrated that the relative risk of an RT-PCR positive case is 51% lower 13-24 days after the first dose compared to 1-12 days after the first dose. That is not the same as demonstrating effectiveness. If you want to demonstrate this you need to analyse the incidence of RT-PCR positive cases in the vaccinated group compared to an unvaccinated group.

It is surprising that the effect of the difference in prevalence of the infection in the general population during the two periods being compared is not accounted for. For example, if the total cases per 100,000 is 40 in the first period and 80 in the second; if 4000 of the inoculated cohort were infected in the first period. It will be statistically expected that without the vaccine 8000 of the cohort would have been infected in the second period. And if actually only 2000 were infected, then the vaccine protected 6000 out of 8000 potential infections, that is 75% efficient. For these numbers, the methodology adopted in the study would calculate only 2000 out of 4000, that is 50%.<br /> Hope my drift is clear, though rustic.

Ok, this is only a preprint. However, a wording like "provides a precise estimate of the true underlying SARS-CoV-2 transmission risk in schools and day-care centres." in the introduction sets all alarm bells of any scientist ringing. "precise" and "true" are bold words, rarely used in serious academic publications (where typically a prominent "threats to validity" section would highlight and discuss the limitations of the findings) - in particular, if the underlying method is relatively weak. Some limitations are discussed on pp.12 and 13, but in a rather superficial way.

Just a few major questions that challenge the overall contribution:

1. During the major part of the period of the analysis, the incidence was very low, in particular among young people. See https://corona-data.eu/medi... for a heatmap. Of the total duration of the study of ca. 17 weeks, only the last 5 - 6 weeks and thus less a mere 30 % had a significant incidence in the age-groups 0-4, 5-9, and 10-14, and it was lower than in the general population.

2. As children are less likely to be symptomatic and the testing regime has a strong bias towards symptomatic patients, it is a valid assumption that the share of undetected infections is higher among students and children than in the general population. As the authors' entire analysis and model for transmission is based on test-confirmed public health cases, the authors should have tested this hypothesis, e.g. by random PCR tests in areas and during periods with a sufficient community incidence. If you miss asymptomatic cases, you are not only invalidating your aggregate statistics, but of course also the entire graph of infections becomes incomplete and questionable.

3. On pp. 6 an 7, the authors cite the official definitions for cases and procedures; however, there is no information whether the theoretical guidelines for contact tracing, testing, non-pharmaceutical interventions like social distancing, masks, ventilation etc. were actually followed, and if the compliance remained stable over the course of the analysis and representative for the different groups. For instance, one could hypothesize that the effect of wearing mask in classrooms after November 20 is partially obscured by a reduction in ventilation due to cool weather and in general more time spent indoors. Taking the textbook definition of a characteristic of an observation and then assuming it to match the data is a significant threat to validity.

4. The same holds for the approach of instructing the DPHAs on how to use the questionnaire but not testing the quality of the results statistically or by cross-validation. How do you know that the DPHAs understood and applied your instructions properly? And even if they did, how do you know that the data they were using was correct? it is not a lot of effort to rule out or estimate the margin of error of a potential weakness.

5. The entire statistical analysis method is only a bit over half a page of largely spaced text (p. 8).

6. The claim that children are less likely to produce a sufficient viral load to infect others is highly disputed in the literature, see e.g. https://zoonosen.charite.de... these findings are not uniformly agreed (see e.g. https://www.sciencemediacen... "https://www.sciencemediacentre.org/expert-reaction-to-a-preprint-looking-at-the-amount-of-virus-from-those-with-covid-19-in-different-age-groups/)"), but it is not commonly accepted that children are unlikely to infect others. This challenges the assumption that asymptomatic individuals are unlikely to infect others even if they are themselves infected.

7. The authors state on p.12 that the rate of asymptomatic infections was relatively low with ca. 17%. Unfortunately, this population aggregate used by the authors obscures the influence of age on the likelihood of asymptomatic infections and hence on the number of undetected infections in school settings. A recent meta-study https://www.frontiersin.org... suggests that the rate is higher in children (p=0.5, CI 0.21 - 0.79) than in adults (p=0.3, CI 0.13 - 0.56). There is a lot of variance observed in the underlying studies, but the order of magnitude could explain a major share of the reported higher likelihood of infections originating from teachers than from students alone.

8. The focus on "hygiene practices" (p.13) as a recommendation conflicts with the widely accepted view that SARS-CoV-2 transmission is largely airborne and that sustained social contact in indoor environments is a high-risk setting, even with masks.

9. If the risk of students in school infecting teachers is so low, one should immediately stop the priority vaccination of teachers. I think the priority vaccination is justified.

For lay people: If children are less likely to show symptoms than adults, and testing and hence becoming an index case is more likely for symptomatic individuals, it will be no surprise that teachers, who are adults, are more often identified as index cases than children. If the data graph of humans interacting in the pandemic is incomplete, and there is a systematic bias that leads to more missing index patients being children, your findings can easily be a simple artifact resulting from the chosen approach.

Now, all science is tentative; we all know our papers could be improved, the evidence or data be more convincing, additional aspects be considered. The problem arises when this is combined with politics. The introduction (p. 5, 2nd paragraph) is heavily focussed on a positive view on re-opening school. The arguments raised are not wrong per se, but they are also not balanced - in a pandemic with a novel virus against which the majority of the human population seems to be immunologically naïve, other societal risks should be given the same space. If you motivate your research with the wish to reopen schools, readers have reason to assume that you are not neutral as to the outcome.

This is all common in the daily struggle of anybody in research and academia.

But when you combine such very preliminary work with substantial threats to validity with a bold claim in the intro and a conclusion in which you report with certainty that only 1 in 100 infected students will infect another person in school, knowing that there is a lot of heated debate in the society, then your "Ethical Statement" should be amended by "We knowingly accept that populist media like BILD, interest groups, and decision makers will use our fragile findings and our wording as solid evidence for a risk-prone opening strategy. Since we are so confident in our research, we take full responsibility for the societal consequences."

Doing preliminary research is unavoidable. Distributing it in a form that is the perfect bait for media and decision makers is unethical.

This is problematic as MRA using GWAS accounts for under 5% of the variance in calcifediol. It certainly does not account for UV exposure, dietary supplementation, sequestration of calcifediol in fat (which underlies the increased risk of COVID in the obese), factors affecting RAAS, seasonal variation, factors affecting FGF23 and 24-hydroxylase.

The authors state that the results do not apply to vitamin D deficiency yet 80% of hospitalizations are in the deficient. The selection of UK Biobank (401,460 of 443,734 cases) where the average calcifediol is 18ng/ml, well below the sufficiency level of 30ng/ml, may be problematic. Some other factor operative-Horizontal effect or collider bias.

The Castillo study (Andalucia) did not use a high dose of calcifediol but rather ????g266/week which is the equivalent of 34,000IU (ie 5000IU/day). The effectiveness of that dosing was confirmed by Nogues et al (Barcelona) in a much larger sample. The Murai study was a farce if only because bolus dosing induces FGF23 and 24-hydroxylation; also the followup was only 7 days.

The authors claim on line 417 that 10 MRA studies were of value but only #23 Trajanoska seems valid, #21 on D2 is wrong (see Dawson Hughes), as are #22 and #24) . MRA analyses of vitamin D have never been valid because of poor association with the phenotype.

Politically biased?

It is surprising and appears bold to include a category "values" (Werte) in a study of drivers of the Corona-pandemic. And if so, to associate it with only two very restricted indicators: the election behaviour for just one political party (out of six) and the creed Catholic, neglecting the main other creeds Protestants, and Muslim.

You state:

"During the period of intense exponential increase in infections, the proportion of the population that voted for the Alternative for Germany (AfD) party in the last federal election was among the top characteristics correlated with high incidence and death rates."

The obvious question is, what was your motivation to select just one political party for your study?

There are these six parties in the German Parliarment (Bundestag), listed here with their results in the 2017 election: CDU/CSU (32.9%), SPD (20.5%), AfD (12.6%), FDP (10.7%), Linke (9.2%), Grüne (8.9%).

It is desirable that you mend this flaw during the peer-review process by considering now all parties and the relevant creeds. As a spin-off you might even explain the currently highest values of infection in Thuringia from the "values" of the gouverning party Die Linke.

A good many issues are of question in regards to this work, after mulling it over a good time. Firstly, evolution is always going on. If one is defining mutations in the most general sense, no treatment alters that rate. However, if one means by mutation the generation of some particularly problematic change causing a variant, then perhaps the logic dealt with here is relevant. Evolution is not a process which can be terminated or quelled, though it may be channeled and controlled! Secondly, a period of about 5.5 months can give some possible resonance to the supposed finding, but the ability to alter progression needs to really have significant follow up. Is the process of some unfavorable change (i.e my latter use of 'mutation' above) really limited or is it only impeded and delayed? A true ability to confirm requires a longer period of analysis and the current argument conclusion may be somewhat presumptuous in its statement. Thirdly, I am concerned that the numbers may yet be a bit too small for the conclusion reached, though running a study with the proper enrolled numbers for such comparisons is probably too problematic to be practical.

I believe there is some evidence here, but perhaps not so complete as to be given the full impact that the conclusion provides. It is likely, but it is not confirmed to nearly the extent that I might desire for such a paper.

Participation bias is a big issue. They asked a lot of people to participate, but only a small percentage did.

The apparent pattern of back mutations at position 142 is an experimental artefact due to errors in some Delta sequences. It emerges from the fact that Delta has SNPs in the primer binding site for ARTIC amplicon 72 (in a previous ARTIC scheme) which often result in the failure to amplify this amplicon, containing the G/D 142 locus, from Delta samples. Small amounts of contamination from other genotypes (e.g. B.1.1.7) that are amplified normally at this location can then lead to an amplicon here (typically with reduced depth). This results in a final sequence which appears to have a back-mutation at this position, and phylogenetic analyses can tend to group such samples together on trees.

T95I is in this same amplicon.

It is likely that the Ct correlations observed here reflect the fact that the correct G142D call is much more likely to be detected despite the low efficiency of amplification for samples with higher viral loads.

Ther are also inconsistencies between the results and the conclusions, e.g. though they found that "Children and adults showed comparable SARS-CoV-2 positivity <br /> rates in most studies" (page 9)" the abstract reads "children are 43% less susceptible than adults".Furthermore in some tables and forest plots, they used as denominator the total of students and staff altogether instead of students only, to estimate the students incidence.

I assume that the EN60601 requires ozone production to be tested for? If ozone is being produced (or destroyed to odd oxygen) that this would need testing before deployment in a medical setting. Ozone, a respiratory irritant gas, will easily travel more than 1.5m (so distance should not be seen as useful in setting safety protocols for electronic air cleaning devices in a medical setting).

Are hospital rooms with no ventilation in line with current infection prevention and control or hospital design / operational guidelines in the UK? In Australia this would be in breach of both our hospital design and operating guidelines which require a minimum of 6 ACH for all hospitals.

The effectiveness of UV with air high flow rates has to be questioned (because the exposure time for bio-aerosols is short) - are the authors able to separate the effectiveness of the filtration over the UV features? Most literature on this point shows that in real-world operation the HEPA provides 99.97% of the removal of bio-aerosols from air and the advantage of UV is untested / unproven (this is particularly true at 1000m3/h flow rates this device is operating at). I assume this device will be noisy >65dB - can this please be specified.

Comment #1: Research in Context

1. Diamond Princess Cruise Ship. The manuscript makes no reference to any epidemiological analysis of this episode, which informed seminal assessments of the age-specific infection fatality rate (IFR) of COVID-19.[1-4] Nonetheless, that evidence is particularly relevant, because the cruise ship’s passengers included 1231 individuals ages 70+ who were not merely “community-dwelling” but healthy enough to embark on a multi-week grand tour of southeast Asia. Following extensive RT-PCR testing, 335 passengers ages 70+ were confirmed to have been infected with SARS-Cov-2, and 13 of those passengers died from COVID-19 – an IFR of about 4%. Moreover, the strong link to age is underscored by the even higher IFR of 8% for passengers ages 80+. Given the size of that sample (which meets the 1000+ threshold used here), this evidence should certainly be incorporated into this meta-analysis.

2. Comprehensive Tracing Programs. The manuscript makes no reference to countries that succeeded in containing the first wave of the pandemic in spring 2020 through systematic tracing and testing of all contacts of infected individuals.[5] Such evidence is particularly relevant here, because the virus was contained within the “community-dwelling” populations of those locations and never spread to any elderly care facilities. For example, in the case of New Zealand, there were 256 infections and 19 deaths among adults ages 70+ -- an IFR of about 7%.

3. Hospitalized Patients. The manuscript cites a single study (published in July 2020) that examined the association between comorbidities and mortality risk of COVID-19.[6] However, that study was not able to distinguish whether comorbidities were linked to greater prevalence (the probability of getting infected) or to a higher IFR (the risk of mortality conditional on infection). Unfortunately, the manuscript makes no reference to any subsequent studies on this issue. In particular, a large-scale study of U.K. BioBank participants found that measures of frailty were indeed associated with higher mortality rates in the overall panel but not linked to mortality within the subset of hospitalized COVID-19 patients.[7] In effect, the prevalence of COVID-19 was markedly higher among residents of U.K. nursing homes compared to individuals of similar age living in the community, but the IFR was not significantly different. Those findings directly contradict a key assertion made at the start of this manuscript.

4. Prior Meta-Analysis of Community-Dwelling Populations. The introduction of this manuscript neglects to mention that an existing meta-analysis study (published in Nature in November 2020) was specifically focused on assessing IFRs excluding deaths in nursing homes.[8] That study estimated the link between age and IFR using seroprevalence and fatality data for adults less than 65 years old, and then showed that the model predictiions were consistent with data on fatalities among community-dwelling adults ages 65+. Moreover, that study used seroprevalence data adjusted for assay characteristics, and the results were obtained using a rigorous Bayesian statistical model that incorporated random variations in the time lags between infection, seropositivity, and fatal outcomes – a striking contrast to this manuscript, which uses rudimentary assumptions to address those issues.

5. Other Meta-Analyses. The introduction of this manuscript briefly refers to two other meta-analysis studies of the link between age and IFR.[5, 9] However, the manuscript then asserts: “Importantly, the vast majority of seroprevalence studies include very few elderly people.” (p.5) That assertion is supported by a single citation to the SeroTracker database, which provides comprehensive coverage of all existing national, regional, and local seroprevalence studies across the globe.[10] However, this assertion is completely incorrect as a characterization of the preceding meta-analysis of age-specific IFRs. As indicated in Levin et al. (2020, figure 5), that meta-analysis study included seroprevalence data on older adults (including narrow brackets for ages 60-69, 65-74, 70-79, and 75-84 as well as open-ended brackets for ages 60+, 65+, 70+, 80+, and 85+) from nine national studies (Belgium, France, Hungary, Italy, Netherlands, Portugal, Spain, Sweden, and the U.K.) and eight regional locations (Ontario, Canada; Geneva, Switzerland; Connecticut, Indiana, Louisiana, Miami, Missouri, and San Francisco, USA).[5]

I don't know why, but medrxiv keeps deleting my warning comments.

So, I write brief comments again.

This study doesn't control important variables as kept suggested in comments and probably the findings are due to spurious correlations.

The one of uncontrolled important variable is "when the infection spread in the country". This study should have used the measure like "number of deaths or patients 10 days after 100th patients were detected in the country". Other analyses are doing that.<br /> The second uncontrolled important variable is "how long the country advanced BCG measure". UK, for example, advanced the BCG measure for more than 50 years. So, majority of nations are experienced with BCG.<br /> The third uncontrolled important variable is GDP. You can see the most of nations without BCG is Western rich countries which can do more tests, which are popular from tourists.<br /> I did analyses controlling these variables, and all the correlations between the length of BCG measure with coronavirus data (how fast the 100th patients were detected in the country, number of patients or deaths ten days after the 100th patients were detected in the country) are all insignificant. They did not even show the statistical tendencies.

Many people have wrong ideas how effective BCG is though this preprint. Somebody has to give warnings. Please do not delete this warning.

I share the concerns expressed in the previous 2 comments. Surely the decrease in antibody levels would be entirely expected after the primary response.

Considering the concerns likely to be raised by their findings, I think it is a serious omission not to compare the data to antibody levels typically seen following primary responses to infections on which we have solid information on long term immunity, (both weak and strong). However this would be a completely academic consideration provided a good secondary response to Covid 19 antigen / virus was seen.

Awareness and vaccination day for Beni mototaxi drivers with the support of Unicef S / Coordination MVE Beni, Wednesday 06-11 - 2019 HIVUM room

• There were many, about three hundred, the drivers of Mototaxi Beni invited to a day of awareness and vaccination against Ebola Virus Disease this Wednesday, November 06, 2019 in the HIVUM room.

• This day is welcome for the city of Beni during this period of EVD epidemic which, unfortunately, displays a lethality of 86.3% among motorcyclists, as pointed out by Dr. Pierre ADIKEY, Coordinator of the response of Sub Coordination of Beni.

• Thus, in his presentation, he focused his message on the risk of transmission of EVD among motorotaxi drivers and the conduct to be held in the exercise of their craft to protect themselves and the community.

• He asked bikers more often to respect the measures of prevention, namely: washing hands regularly, stopping at checkpoints, not being bribed to divert checkpoints, not carrying suspicious parcels and reporting and / or direct any suspicions of illness to colleagues or the community.

• In order to circumscribe the day, Dr. P. ADIKEY traced the path of the last Motard who died of EVD before his death confirmed at the CTE. To close his presentation, he made a reminder of the various events that prevented the teams of the response from working: among other things the days of the dead city, the fire of the vehicles of the riposte, the destruction of the structures of the care, the cases of resistance and others whose bikers were part of it.

• Dr. Bibiche MATADY, as Epidemiologist and Chair of the Monitoring Commission, introduced to the participants the importance of accepting to be listened to if you are in contact with a case, to let yourself be followed for the entire period indicated and to orient in a management structure as soon as the first sign appears. She also emphasized the collaboration between the bikers and the teams of the response.

• To justify this day again, one of the 3 Hikers shared his testimony and urged his colleagues to collaborate and follow the recommendations of the response teams starting with vaccination.

• Vaccination is one of the preventive measures against EVD, said Dr Adonis TERANYA, the Chair of the Immunization Subcommission. In his presentation, he explained the evolution of the vaccination protocol, the current targets, the side effects and the action to take in the event of an adverse event. Before calling for the voluntary vaccination of participants, he spoke about vaccines currently used in the DRC.

• In his words, the President of Bikers reiterated to the Coordinator the commitment of his organization and all its members to support the interventions of the response, while affirming its availability to any solicitation for the fight against the disease to Ebola virus in the city of Beni and its surroundings.

• The day ended with the vaccination of 100 Bikers and some of their dependents.

VACCINATION

• Since vaccination began on 8 August 2018, 250,234 people have been vaccinated;
• The only vaccine to be used in this outbreak is the rVSV-ZEBOV vaccine, manufactured by the pharmaceutical group Merck, following approval by the Ethics Committee in its decision of 20 May 2018.

MONITORING AT ENTRY POINTS

• Since the beginning of the epidemic, the total number of travelers checked (temperature rise) at the sanitary control points is 115,778,240 ;
• To date, a total of 111 entry points (PoE) and sanitary control points (PoCs) have been set up in the provinces of North Kivu and Ituri to protect the country's major cities and prevent the spread of the epidemic in neighboring countries.

As a reminder, the recommendations of the MULTISECTORAL COMMITTEE OF THE RESPONSE TO EBOLA VIRUS DISEASE are as follows:

1. Follow basic hygiene practices, including regular hand washing with soap and water or ashes;
2. If an acquaintance from an epidemic area comes to visit you and is ill, do not touch her and call the North Kivu Civil Protection toll-free number;
3. If you are identified as a contact of an Ebola patient, agree to be vaccinated and followed for 21 days;
4. If a person dies because of Ebola, follow the instructions for safe and dignified burials. It is simply a funeral method that respects funerary customs and traditions while protecting the family and community from Ebola contamination.
5. For all health professionals, observe the hygiene measures in the health centers and declare any person with symptoms of Ebola (fever, diarrhea, vomiting, fatigue, anorexia, bleeding).<br /> If all citizens respect these health measures recommended by the Secretariat, it is possible to quickly end this 10th epidemic.

The results on T-cells is quite murky here, without much explanation. You really need a bigger sample to be able to see this better, your sample of 46 is too small.

There is another study that puts the R0 value in 1.4 to 2.6, still very high.<br /> However not apocaliptic levels like the one described here.<br /> Also, this R0 value can change in time as long as the adequate restrictions are taken in place.<br /> So, yeah guys, expect the best, have some precautions and happy lunar new year.
