COVID-19 simulation models are mathematical infectious disease models for the spread of COVID-19. [1] The list should not be confused with COVID-19 apps used mainly for digital contact tracing . Note that some of the applications listed are website-only models or simulators, and some of those rely on (or use) real-time data from other sources.
The software should be distinguished from the ICL's COVID-19 Scenario Analysis Tool (currently Version 4 [11]), which is hosted under the domain name https://www.covidsim.org, but according to the research documentation is relying on the model combined with a squire model, which is the underlying transmission model in the absence of vaccination.
The transmission of COVID-19 is the passing of coronavirus disease 2019 from person to person. COVID-19 is mainly transmitted when people breathe in air contaminated by droplets/aerosols and small airborne particles containing the virus. Infected people exhale those particles as they breathe, talk, cough, sneeze, or sing.
In April 2020, the model was called "perhaps the most widely cited coronavirus model" by The Colorado Sun [1] and "America's most influential coronavirus model" by The Washington Post. [2] Its projections were cited during White House briefings in March–April 2020. [3] Critics say the model uses flawed methods and should not guide U.S. policies.
During the initial outbreak in Wuhan, China, various names were used for the virus; some names used by different sources included "the coronavirus" or "Wuhan coronavirus". [ 27 ] [ 28 ] In January 2020, the World Health Organization (WHO) recommended "2019 novel coronavirus" (2019-nCoV) [ 5 ] [ 29 ] as the provisional name for the virus.
On 26 November 2021, the WHO asked nations to enhance surveillance and sequencing efforts, submit complete genome sequences and associated metadata to a publicly available database, such as GISAID, report initial cases/clusters associated with virus-of-concern infection to the WHO through the International Health Regulations (IHR) mechanism ...
There are three broad categories of coronavirus tests in the U.S. Two diagnose whether you have an active infection, and a third indicates if you previously had the virus. Here’s how they work:
SARS-CoV-2, the causative agent of COVID-19, was first introduced to humans through zoonosis (transmission of a pathogen to a human from an animal), and a zoonotic spillover event is the origin of SARS-CoV-2 that is considered most plausible by the scientific community.
