Coronavirus Update (Live): 7,582,164 Cases and 423,067 Deaths from COVID-19 Virus Pandemic - Worldometer

How dangerous is the virus? There are three parameters to understand in order to assess the magnitude of the risk posed by this novel coronavirus: Transmission Rate (Ro) - number of newly infected people from a single caseCase Fatality Rate (CFR) - percent of cases that result in death Determine whether asymptomatic transmission is possible How contagious is the Wuhan Coronavirus? (Ro) The attack rate or transmissibility (how rapidly the disease spreads) of a virus is indicated by its reproductive number (Ro, pronounced R-nought or r-zero), which represents the average number of people to which a single infected person will transmit the virus. WHO's estimated (on Jan. 23) Ro to be between 1.4 and 2.5. [13] Other studies have estimated a Ro between 3.6 and 4.0, and between 2.24 to 3.58. [23]. Preliminary studies had estimated Ro to be between 1.5 and 3.5. [5][6][7] An outbreak with a reproductive number of below 1 will gradually disappear. See full details: Coronavirus Fatality Rate

The History of Pandemics, by Death Toll Pan·dem·ic /panˈdemik/ (of a disease) prevalent over a whole country or the world. As humans have spread across the world, so have infectious diseases. Even in this modern era, outbreaks are nearly constant, though not every outbreak reaches pandemic level as COVID-19 has.

Workplace parties should consider whether doing certain tasks puts employees at greater risk of exposure to coronavirus. How coronavirus spread across the globe - visualised Since New Year’s Eve the world has lived through 100 days of Covid-19. There have been over 1.3m confirmed cases, and over 75,000 deaths. Billions of people are confined to their homes and stock markets have plummeted. Here is how the crisis unfolded.

20 of the worst epidemics and pandemics in history Throughout the course of history, disease outbreaks have ravaged humanity, sometimes changing the course of history and, at times, signaling the end of entire civilizations. Here are 20 of the worst epidemics and pandemics, dating from prehistoric to modern times. 1. Prehistoric epidemic: Circa 3000 B.C. COVID-19 Community Mobility Reports Each Community Mobility Report is broken down by location and displays the change in visits to places like grocery stores and parks. Learn more about the data. We’re working to add more countries, regions and languages in the coming weeks.

COVIDView Weekly Summary Two syndromic surveillance systems are being used to monitor trends in outpatient and emergency department visits that may be related to COVID-19. Each system monitors a slightly different syndrome, and together these systems provide a more comprehensive picture of mild to moderate COVID-19 illness than either would individually. Both systems are currently being affected by recent changes in healthcare seeking behavior, including increasing use of telemedicine and recommendations to limit emergency department (ED) visits to severe illness, as well as increased social distancing. These changes affect the numbers of people and their reasons for seeking care in the outpatient and ED settings.

Government response - Australian Government Department of Health What we aim to do The Australian Government’s health response to the COVID-19 outbreak aims to: minimise the number of people becoming infected or sick with COVID-19minimise how sick people become and the mortality ratemanage the demand on our health systemshelp you to manage your own risk and the risk to your families and communities Who manages the response esri As hundreds of millions of eyes stay glued to the rising toll and reach of the novel coronavirus disease 2019 (COVID-19), map-based dashboards have become a compelling, near real-time way to monitor the outbreak. They’ve also substantiated the message that everyone must take precautions and alter daily interactions. When the World Health Organization (WHO) declared COVID-19 a pandemic, director-general Tedros Adhanom Ghebreyesus warned that the situation would worsen. Yet, he noted, this is the first world pandemic that can be controlled, in part due to global connectivity and awareness. The controllability of COVID-19 can also be attributed to tools that quantify data inputs—and aggregate information about who and when in the context of where.

What the 1918 flu pandemic can teach us about coronavirus drug trials Sometimes the parallels between this pandemic and previous ones are uncanny. Take hydroxychloroquine, the anti-malarial drug that regulatory agencies all over the world are now hastily authorising for the treatment of hospitalised Covid-19 patients. Outside hospitals, Donald Trump and the Brazilian president, Jair Bolsonaro, have expressed enthusiasm for the drug, people are breaking social distancing rules to get it, and there have been cases of poisoning due to inappropriate self-medication. The run on hydroxychloroquine is the result of a small trial being conducted at a hospital in Marseille that, though promising, has not yet provided the required standard of proof that the medicine works for Covid-19 – let alone information about when it works, or in what doses.

COVID-19 Pandemic Planning Scenarios Table 1. Parameter Values that vary among the five COVID-19 Pandemic Planning Scenarios. The scenarios are intended to advance public health preparedness and planning. They are not predictions or estimates of the expected impact of COVID-19. The parameter values in each scenario will be updated and augmented over time, as we learn more about the epidemiology of COVID-19. Considerations for Schools As some communities in the United States open K-12 schools, CDC offers the following considerations for ways in which schools can help protect students, teachers, administrators, and staff and slow the spread of COVID-19. Schools can determine, in collaboration with state and local health officials to the extent possible, whether and how to implement these considerations while adjusting to meet the unique needs and circumstances of the local community. Implementation should be guided by what is feasible, practical, acceptable, and tailored to the needs of each community. School-based health facilities may refer to CDC’s Guidance for U.S.
