People don't just act in response to official orders. People react to the perception of danger, and by the time various official responses were announced, they were already taking measures to prevent the spread of COVID-19 (some more effective than others). For example, look at the mobility data for New York: By the time the lockdown started on March 22, ...

Well, there is one meta-analytical estimate of the IFR for Covid-19 out already albeint only as a draft paper: there were 13 estimates of IFR included in the final meta-analysis, from a wide range of countries, published between February and April 2020. The meta-analysis demonstrated a point-estimate of IFR of 0.75% (0.49-1.01%) with significant ...

This must depend on the local situation. At the beginning of the pandemic Japanese Hospitals were admitting PCR positive asymptomatic patients. Then as the disease spread Chinese authorities in Hubei were creating field hospitals (sixteen Fang Cang hospitals in Wuhan ) to house the less symptomatic patients and leaving the hospitals with ICU facilities to ...

I haven't seen any evidence that the actual death rate has changed at all. See this Q&A: Does COVID-19 have a case fatality rate of 41%? Is this formula correct? The ratio of "deaths/(recoveries+deaths)" does not describe the actual case fatality rate Early in the pandemic, when there are lots of new people infected, almost all of the cases were ...

I don't have a concrete technical answer to this (regarding CDC's precise definition--they have a lot of pages on V-safe as how to participate in it, but no other published results besides those slides, it seems), but note that the same presentation puts anaphylaxis in a separate category (there were 6 cases in the same sample). As far as the (higher) ...

Look at the footer of the charts: "Each day shows new cases reported since the previous day" (emphasis mine). The virus doesn't care what day of the week it is, but the office staff at the hospital do. In many hospitals (and coroner's offices, and similar places), the people responsible for reporting on cases and deaths don't work on the weekends,...

While people don't usually have a preference for dying on particular days determining how they died is subjected to delays. A medical examiner or other expert had to determine whether the death is from covid-19 or one of the many comorbid conditions that the person suffered from. Furthermore, there are deaths in the community that need to be examined. You ...

While hospitals, clinics, long term care homes and such are of course open and working seven days a week, administrative staff typically only work 5 days a week. So someone comes to work Monday and reports 3 deaths (that may actually have occurred on Saturday or Sunday.) They may not do that first thing Monday, they may have other things going on. ...

I haven't seen a lot of research on these intra-weekly (reporting) trends on anything health-related, but there is one paper on such trend on ILI reporting, alas just in the military: In this report, we describe and analyze a periodic pattern in influenza-like illness within active military populations, derived from the Defense Medical Surveillance System ...

Seasonal and cyclical effects have been studied prior to COVID-19, including day-of-week influences on Emergency Department visit volume. For example, in a study of emergency departments in Western New York: “The final ARMA (2,0) model indicated an autoregressive structure with up to a 2-day lag. ED volume is lower on weekends than on weekdays, and ...

It's just a medical hypothesis that because BCG might offer some protection against viruses and bacterial infection, it might offer some protection against SARS-CoV-2. There is an Australian study in progress to see if it helps protect health workers. https://clinicaltrials.gov/ct2/show/NCT04327206 But given that BCG has been in world wide short supply ...

I recommend this github project from the Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE): https://github.com/CSSEGISandData/COVID-19 They collect the official numbers from different organizations and ministries from all over the world and update their repository every day. They don't provide information about the age of ...

https://www.arcgis.com/apps/opsdashboard/index.html#/bda7594740fd40299423467b48e9ecf6 We are tracking the COVID-19 spread in real-time on our interactive dashboard with data available for download. We are also modeling the spread of the virus. Preliminary study results are discussed on our blog. This is by the John Hopkins University.

If you look at the graphs you referenced you can see that the data for South Korea and Japan are totally different. South Korea's infection rate has fallen, and continues to do so. Taiwan's cases don't even register which shows that Taiwan is doing even better than South Korea. Japan, however, has failed to reduce their infection rates which continue to ...

You're looking at a non-peer-reviewed study with some sloppy conventions. There is not enough information contained in the paper to answer your questions about it. You can assume what you want for many of your questions, but they are better directed at the authors, who have not indicated when they present means or medians, standard deviations or IQR, etc. It'...

Around 1 to 2%. While @Fizz and @Dale Newton have already provided a nice collection (with statistics even), I'd like to add one more, which is based on common sense as well as statistics. First off, the source should be such that it could reasonably be expected to report truthful data; that pretty much means democratic governments which are taking this ...

On the same CDC website, there is a section titled: COVID-19 Mortality Overview A link on this page (last but one) leads to a detailed analysis of comorbidalities: Most Frequently Listed Comorbidities with COVID-19 Deaths and also adds that as of 2nd Feb 2021, deaths involving: Influenza/Pneumonia (44%) Hypertension (20%) Diabetes (16%) Dementias (15%) ...

The TCID50 (Median Tissue Culture Infectious Dose) is one of the methods used when verifying viral titer. TCID50 signifies the concentration at which 50% of the cells are infected when a test tube or well plate upon which cells have been cultured is inoculated with a diluted solution of viral fluid. So, in the second paper they're talking about the amount ...
