COVID-19 Pandemic In São Tomé And Príncipe
The COVID-19 pandemic in São Tomé and Príncipe is part of the worldwide pandemic of coronavirus disease 2019 () caused by severe acute respiratory syndrome coronavirus 2 (). The virus was confirmed to have reached São Tomé and Príncipe on 6 April 2020. The first death was recorded on 30 April. Background On 12 January 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 WHO on 31 December 2019. The case fatality ratio for COVID-19 has been much lower than SARS of 2003, but the transmission has been significantly greater, with a significant total death toll. Model-based simulations indicate that the 95% confidence interval for the time-varying reproduction number ''Rt'' of São Tomé and Príncipe was below 1.0 in May and June 2020 but has since increased to around 1.

Coronavirus Disease 2019
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 seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basic Reproduction Number
In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted R_0 (pronounced ''R nought'' or ''R zero''), of an infection is the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection. The definition assumes that no other individuals are infected or immunized (naturally or through vaccination). Some definitions, such as that of the Australian Department of Health, add the absence of "any deliberate intervention in disease transmission". The basic reproduction number is not necessarily the same as the effective reproduction number R (usually written R_t 't'' for time sometimes R_e), which is the number of cases generated in the current state of a population, which does not have to be the uninfected state. R_0 is a dimensionless number (persons infected per person infecting) and not a time rate, which would have units ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disease Outbreaks In São Tomé And Príncipe
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and fu ...

COVID-19 Pandemic By Country
This is a general overview and status of places affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus which causes coronavirus disease 2019 (COVID-19) and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 were identified in Wuhan, the capital of the province of Hubei in China in December 2019. The figures presented are based on reported cases and deaths. While in several high-income countries the ratio of total estimated cases and deaths to reported cases and deaths is low and close to 1, for some countries it may be more than 10 or even more than 100. Implementation of COVID-19 surveillance methods varies widely. Maps and timelines Total cases World maps showing total confirmed cases, and total confirmed cases per million, by country.

COVID-19 Pandemic In Africa
The COVID-19 pandemicpandemic was confirmed to have spread to Africa on 14 February 2020, with the first confirmed case announced in Egypt. The first confirmed case in sub-Saharan Africa was announced in Nigeria at the end of February 2020. Within three months, the virus had spread throughout the continent, as Lesotho, the last African sovereign state to have remained free of the virus, reported a case on 13 May 2020. By 26 May, it appeared that most African countries were experiencing community transmission, although testing capacity was limited. Most of the identified imported cases arrived from Europe and the United States rather than from China where the virus originated. In early June 2021, Africa faced a third wave of COVID infections with cases rising in 14 countries. By 4 July the continent recorded more than 251,000 new Covid cases, a 20% increase from the prior week and a 12% increase from the January peak. More than sixteen African countries, including Malawi and S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

COVAX
COVID-19 Vaccines Global Access, abbreviated as COVAX, is a worldwide initiative aimed at equitable access to COVID-19 vaccines directed by the GAVI vaccine alliance, the Coalition for Epidemic Preparedness Innovations (CEPI), and the World Health Organization (WHO), alongside key delivery partner UNICEF. It is one of the four pillars of the Access to COVID-19 Tools Accelerator, an initiative begun in April 2020 by the WHO, the European Commission, and the government of France as a response to the COVID-19 pandemic. COVAX coordinates international resources to enable low-to-middle-income countries equitable access to COVID-19 tests, therapies, and vaccines. UNICEF is the key delivery partner, leveraging its experience as the largest single vaccine buyer in the world and working on the procurement of COVID-19 vaccine doses, as well as logistics, country readiness and in-country delivery. By 19 October 2020, 184 countries had joined COVAX. COVAX began distributing vaccines in Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford–AstraZeneca COVID-19 Vaccine
The Oxford–AstraZeneca COVID19 vaccine, sold under the brand names Covishield and Vaxzevria among others, is a viral vector vaccine for prevention of COVID-19. Developed in the United Kingdom by Oxford University and British-Swedish company AstraZeneca, using as a vector the modified chimpanzee adenovirus ChAdOx1. The vaccine is given by intramuscular injection. Studies carried out in 2020 showed that the efficacy of the vaccine is 76.0% at preventing symptomatic COVID-19 beginning at 22 days following the first dose, and 81.3% after the second dose. A study in Scotland found that, for symptomatic COVID-19 infection after the second dose, the vaccine is 81% effective against the Alpha variant (lineage B.1.1.7), and 61% against the Delta variant (lineage B.1.617.2). The vaccine is stable at refrigerator temperatures and has a good safety profile, with side effects including injection-site pain, headache, and nausea, all generally resolving within a few days.
