For ID NOW, the average sensitivity was 73.0% with an average specificity of 99.7%; for Xpert Xpress the average sensitivity was 100% with an average specificity of 97.2%. [33] [34] In a diagnostic test, sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can identify true ...
Flattening the curve is a public health strategy to slow down the spread of an epidemic, used against the SARS-CoV-2 virus during the early stages of the COVID-19 pandemic. The curve being flattened is the epidemic curve, a visual representation of the number of infected people needing health care over time. During an epidemic, a health care ...
It was used for medical research. In March 2020 it became the world's first system to reach one exaFLOPS [45] [46] [47] and reached approximately 2.43 x86 exaFLOPS by 13 April 2020 – many times faster than Summit, the fastest supercomputer of that time. [48] That month Rosetta@home joined the effort. Researchers announced that Rosetta@home ...
One way to estimate COVID-19 deaths that includes unconfirmed cases is to use the excess mortality, which is the overall number of deaths that exceed what would normally be expected. [4] From March 1, 2020, through the end of 2020, there were 522,368 excess deaths in the United States, or 22.9% more deaths than would have been expected in that ...
As of March 2024, the Centers for Disease Control and Prevention no longer advises a five-day isolation period when you test positive for COVID-19, but recommends taking other precautions once ...
The timeline of the COVID-19 pandemic lists the articles containing the chronology and epidemiology of SARS-CoV-2, [1] the virus that causes the coronavirus disease 2019 and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [2]
From the date a state passed a threshold of 25 deaths, the statistical study observed a largely uniform development, independently from type and time frame of governmental interactions. Thus, the growth rate of casualties dropped to zero within 20–30 days, and the variability between regions was low, except at the beginning of the epidemics.
The development of COVID-19 tests was a major public health priority during the early months of the COVID-19 pandemic. In January 2020, scientists from China published the first genetic sequences of SARS-CoV-2 via virological.org , [ 3 ] a "hub for prepublication data designed to assist with public health activities and research".
