COVID-19 Pandemic In Mexico
The COVID-19 pandemic in Mexico is part of the ongoing worldwide pandemic of coronavirus disease 2019 () caused by severe acute respiratory syndrome coronavirus 2 (). The virus was confirmed to have reached Mexico in February 2020. However, the National Council of Science and Technology (CONACYT) reported two cases of COVID-19 in mid-January 2020 in the states of Nayarit and Tabasco, with one case per state. The Secretariat of Health, through the ''"Programa Centinela"'' (Spanish for "Sentinel Program"), estimated in mid-July 2020 that there were more than 2,875,734 cases in Mexico because they were considering the total number of cases confirmed as just a statistical sample. Background On January 12, 2020, the World Health Organization (WHO) confirmed that a novel coronavirus was the cause of a respiratory illness in a cluster of people in Wuhan City, Hubei Province, China, which was reported to the World Health Organization (WHO) on December 31, 2019. The case f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Outbreak Active Cases In Mexico
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 are variable but often include fever, cough, headache, fatigue, breathing difficulties, loss of smell, and loss of taste. Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected 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, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction). Older people are at a higher risk of developing severe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sampling (statistics)
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question. Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probability theory and statistical theory are employed to guide the practice. In business and medical research, sampling is widely used for gathering information about a population. Acceptance sampling is used to determine if ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Education In Mexico
Education in Mexico has a long history. Indigenous peoples created institutions such as the telpochcalli and the calmecac. The Royal and Pontifical University of Mexico, the second oldest university in the Americas, was founded by royal decree in 1551. Education in Mexico was, until the early twentieth century, largely confined to males from urban and wealthy segments and under the auspices of the Catholic Church. The Mexican state has been directly involved in education since the nineteenth century, promoting secular education. Control of education was a source of an ongoing conflict between the Mexican state and the Catholic Church, which since the colonial era had exclusive charge of education. The mid-nineteenth-century Liberal Reform separated church and state, which had a direct impact on education. President Benito Juárez sought the expansion of public schools. During the long tenure of President Porfirio Díaz, the expansion of education became a priority under a cabinet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathematical Modelling Of Infectious Disease
Mathematical models can project how infectious diseases progress to show the likely outcome of an epidemic (including in plants) and help inform public health and plant health interventions. Models use basic assumptions or collected statistics along with mathematics to find parameters for various infectious diseases and use those parameters to calculate the effects of different interventions, like mass vaccination programs. The modelling can help decide which intervention(s) to avoid and which to trial, or can predict future growth patterns, etc. History The modeling of infectious diseases is a tool that has been used to study the mechanisms by which diseases spread, to predict the future course of an outbreak and to evaluate strategies to control an epidemic. The first scientist who systematically tried to quantify causes of death was John Graunt in his book ''Natural and Political Observations made upon the Bills of Mortality'', in 1662. The bills he studied were listings of nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Pandemic In The United States
The COVID-19 pandemic in the United States is a part of the COVID-19 pandemic, worldwide pandemic of COVID-19, coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In the United States, it has resulted in confirmed cases with all-time deaths, the most of any country, and COVID-19 pandemic death rates by country, the twentieth-highest per capita worldwide. The COVID-19 pandemic ranks first on the list of disasters in the United States by death toll; it was the third-leading cause of death in the U.S. in 2020, behind heart disease and cancer. From 2019 to 2020, U.S. life expectancy dropped by 3years for Hispanic and Latino Americans, 2.9years for African Americans, and 1.2years for white Americans. These effects persisted as U.S. deaths due to COVID-19 in 2021 exceeded those in 2020, and life expectancy continued to fall from 2020 to 2021. On December 31, 2019, China announced the discovery of a cluster of pne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Pandemic In South Korea
The COVID-19 pandemic in South Korea is part of the 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 Province in China. South Korea introduced what was considered on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Pandemic In Thailand
The COVID-19 pandemic in Thailand is part of the worldwide pandemic of coronavirus disease 2019 () caused by severe acute respiratory syndrome coronavirus 2 (). Thailand was the first country to report a case outside China, on 13 January 2020. , the country has reported a cumulative total of 3,684,755 confirmed cases, with 25,318 deaths from the disease, and currently ranked fourth in the number of cases in Southeast Asia, behind Vietnam, Indonesia, and Malaysia. Thailand was relatively successful in containing the pandemic throughout most of 2020, but has been experiencing an uncontrolled resurgent outbreak since April 2021. An initial wave of infections, mostly traced to nightlife venues and a boxing match in Bangkok, peaked on 22 March 2020 at 188 newly confirmed cases per day. As preventive measures were implemented, the outbreak subsided by May, and the country reported almost no locally transmitted infections until December, when it saw a surge of infections primaril ...

COVID-19 Pandemic In Mainland China
The COVID-19 pandemic in mainland China is part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). China was the first country to experience an outbreak of the disease, the first to impose drastic measures in response (including lockdowns and face mask mandates), and one of the first countries to bring the outbreak under control. The 2019–2020 COVID-19 outbreak in mainland China was the first wave of the disease, and was first manifested as a cluster of mysterious pneumonia cases, mostly related to the Huanan Seafood Market, in Wuhan, the capital of Hubei province. It was first reported to the local government on 27 December 2019 and published on 31 December. On 8 January 2020, a new coronavirus (SARS-CoV-2) was identified as the cause of the pneumonia by Chinese scientists. By 29 January, the virus was found to have spread to all provinces of mainland China. By late February, the pand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pathogen Transmission
In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected. The term strictly refers to the transmission of microorganisms directly from one individual to another by one or more of the following means: * airborne transmission – very small dry and wet particles that stay in the air for long periods of time allowing airborne contamination even after the departure of the host. Particle size 5 μm. * direct physical contact – touching an infected individual, including sexual contact * indirect physical contact – usually by touching a contaminated surface, including soil (fomite) * fecal–oral transmission – usually from unwashed hands, contaminated food or water sources due to lack of sanitation and hygiene, an important transmission route in pediatrics, veterinary medicine an ...

SARS
Severe acute respiratory syndrome (SARS) is a viral respiratory disease of zoonotic origin caused by the severe acute respiratory syndrome coronavirus (SARS-CoV or SARS-CoV-1), the first identified strain of the SARS coronavirus species, ''severe acute respiratory syndrome–related coronavirus'' (SARSr-CoV). The first known cases occurred in November 2002, and the syndrome caused the 2002–2004 SARS outbreak. 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 epidemic in June 2003, the incidence was 8,469 cases with a case fatality rate (CFR ...

Case Fatality Rate
In epidemiology, case fatality rate (CFR) – or sometimes more accurately case-fatality risk – is the proportion of people diagnosed with a certain disease, who 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 represents a measure of disease lethality and 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
