COVID-19 Pandemic In Russia
The COVID-19 pandemic in Russia was a part of the pandemic of coronavirus disease 2019 () caused by severe acute respiratory syndrome coronavirus 2 (). The virus was confirmed to have spread to Russia on 31 January 2020, when two Chinese citizens in Tyumen (Siberia) and Chita (Russian Far East) tested positive for the virus. Early prevention measures included restricting the China–Russia border and extensive testing. The infection spread from Italy on 2 March, leading to additional measures such as cancelling events, closing schools, theatres, and museums, as well as shutting the border and declaring a non-working period which, after two extensions, lasted until 11 May 2020. By the end of March 2020, COVID-19 lockdowns were imposed by the majority of federal subjects of Russia, including Moscow. By the end of 2021, there were nearly 10.5 million cases and nearly 310,000 deaths in the country. Russia had the tenth-highest number of confirmed cases in the world, after the Un ...

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 can vary but often include fever, fatigue, cough, breathing difficulties, anosmia, loss of smell, and ageusia, loss of taste. Symptoms may begin one to fourteen days incubation period, after exposure to the virus. At least a third of people who are infected asymptomatic, do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia (medical), hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock (circulatory), shock, or organ dysfunction, multiorgan dysfunction). Older people have a higher risk of developing severe symptoms. Some complicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Pandemic In India
The COVID-19 pandemic in India is a part of the COVID-19 pandemic, worldwide pandemic of COVID-19, coronavirus disease 2019 () caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As of , according to Indian government figures, India has the second-highest number of confirmed cases in the world (after the COVID-19 pandemic in the United States, United States) with reported cases of COVID-19 infection and the third-highest number of COVID-19 deaths (after the United States and COVID-19 pandemic in Brazil, Brazil) at deaths. In October 2021, the World Health Organization estimated 4.7 million excess deaths, both directly and indirectly related to COVID-19 to have taken place in India. The first cases of COVID-19 in India were reported on 30 January 2020 in three towns of Kerala, among three Indian medical students who had returned from Wuhan, the epicenter of the pandemic. Lockdowns were announced in Kerala on 23 March, and in the rest of the country on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incubation Period
Incubation period (also known as the latent period or latency period) is the time elapsed between exposure to a pathogenic organism, a chemical, or ionizing radiation, radiation, and when symptoms and signs are first apparent. In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host. While ''latent'' or ''latency period'' may be synonymous, a distinction is sometimes made whereby the latent period (epidemiology), latent period is defined as the time from infection to infectiousness. Which period is shorter depends on the disease. A person may carry a disease, such as ''Streptococcus'' in the throat, without exhibiting any symptoms. Depending on the disease, the person may or may not be contagious disease, contagious during the incubation period. During latency, an infection is subclinical. With respect to viral infections, in incubation the virus is replicating. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Case Fatality Rate
In epidemiology, case fatality rate (CFR) – or sometimes more accurately case-fatality risk – is the proportion of people who have been diagnosed with a certain disease and end up dying of it. Unlike a disease's mortality rate, the CFR does not take into account the time period between disease onset and death. A CFR is generally expressed as a percentage. It is a measure of disease lethality, and thus may change with different treatments. CFRs are most often used for with discrete, limited-time courses, such as acute infections. Terminology The ''mortality rate'' – often confused with the CFR – is a measure of the relative number of deaths (either in general, or due to a specific cause) within the entire population per unit of time. A CFR, in contrast, is the number of deaths among the number of diagnosed cases only, regardless of time or total population. From a mathematical point of view, by taking values between 0 and 1 or 0% and 100%, CFRs are actually a measure of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SARS
Severe acute respiratory syndrome (SARS) is a viral respiratory disease of zoonotic origin caused by the virus SARS-CoV-1, the first identified strain of the SARS-related coronavirus. The first known cases occurred in November 2002, and the syndrome caused the 2002–2004 SARS outbreak. In 2004, Xue Wu Zhang and Yee Leng Yap found that the Spike 2 (S2) protein of SARS is structurally similar to HIV-1 gp41 subunit, suggesting an analogous membrane fusion mechanism between the two. In the 2010s, Chinese scientists traced the virus through the intermediary of Asian palm civets to cave-dwelling horseshoe bats in Xiyang Yi Ethnic Township, Yunnan.The locality was referred to be "a cave in Kunming" in earlier sources because the Xiyang Yi Ethnic Township is administratively part of Kunming, though 70 km apart. Xiyang was identified on * For an earlier interview of the researchers about the locality of the caves, see: SARS was a relatively rare disease; at the end of the ep ...

Novel Coronavirus
Novel coronavirus (nCoV) is a provisional name given to coronaviruses of medical significance before a permanent name is decided upon. Although coronaviruses are endemic in humans and infections normally mild, such as the common cold (caused by human coronaviruses in ~15% of cases), cross-species transmission has produced some unusually virulent strains which can cause viral pneumonia and in serious cases even acute respiratory distress syndrome and death. Species The following viruses could initially be referred to as "novel coronavirus", before being formally named: All four viruses are part of the ''Betacoronavirus'' genus within the coronavirus family. Etymology The word "novel" indicates a "new pathogen of a previously known type" (''i.e.'' known family) of virus. Use of the word conforms to best practices for naming new infectious diseases published by the World Health Organization (WHO) in 2015. Historically, diseases have sometimes been named after locations, indivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Health Organization

Mortality Displacement
In epidemiology, the excess deaths or excess mortality is a measure of the increase in the number of deaths during a time period and/or in a certain group, as compared to the expected value or statistical trend during a reference period (typically of five years) or in a reference population. It may typically be measured in percentage points, or in number of deaths per time unit. A short period of excess mortality that is followed by a compensating period of mortality deficit (i.e., fewer deaths than expected, because those people have died at a younger age) is quite common, and is also known as "harvesting". Mortality deficit in a particular time period can be caused by deaths displaced to an earlier time (due to harvesting by an event in the past) or deaths displaced to a future time (due to lives being saved, also called "avoided mortality"). Mortality displacement is the occurrence of deaths at an earlier time than they would have otherwise occurred, meaning the deaths are '' ...

Federal State Statistics Service (Russia)
The Federal State Statistics Service (, abbreviated as Rosstat) is the List of national and international statistical services, governmental statistics agency in Russia. Since 2017, it is again part of the Ministry of Economic Development (Russia), Ministry of Economic Development, having switched several times in the previous decades between that ministry and being directly controlled by the federal government. History Soviet era Goskomstat (, or, in English, the ''State Committee for Statistics'') was the centralised agency dealing with statistics in the Soviet Union. Goskomstat was created in 1987 to replace the Central Statistical Directorate, while maintaining the same basic functions in the collection, analysis, publication and distribution of state statistics, including economic, social and population statistics. This renaming amounted to a formal demotion of the status of the agency. In addition to overseeing the collection and evaluation of state statistics, Goskomsta ...

COVID-19 Pandemic In The United Kingdom
The COVID-19 pandemic in the United Kingdom is a part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In the United Kingdom, it has resulted in confirmed cases, and is associated with deaths up to 26 January 2025. The virus began circulating in the country in early 2020, arriving primarily from travel elsewhere in Europe. Various sectors responded, with more widespread public health measures incrementally introduced from March 2020. The first wave was at the time one of the world's largest outbreaks. By mid-April the peak had been passed and restrictions were gradually eased. A second wave, with a new variant that originated in the UK becoming dominant, began in the autumn and peaked in mid-January 2021, and was deadlier than the first. The UK started a COVID-19 vaccination programme in early December 2020. Generalised restrictions were gradually lifted and were mostly ended by Augus ...

COVID-19 Pandemic In South Korea
The COVID-19 pandemic in South Korea is part of the COVID-19 pandemic, worldwide pandemic of coronavirus disease 2019 () caused by severe acute respiratory syndrome coronavirus 2 (). The first case in South Korea was announced on 20 January 2020. The number of confirmed cases increased on 19 February by 20, and on 20 February by 58 or 70, giving a total of 346 confirmed cases on 21 February 2020, according to the Korea Disease Control and Prevention Agency (KDCA), with the sudden jump mostly attributed to "Patient 31" who participated in a gathering at a Shincheonji Church of Jesus the Temple of the Tabernacle of the Testimony church in Daegu. Amidst fears of further contamination, mass gatherings in the affected cities were cancelled and about 300 soldiers in Daegu were placed in isolation. On 4 February 2020, in order to help prevent spread of the disease, South Korea began denying entry to foreigners traveling from Hubei, Hubei Province in China. South Korea introduced ...
