The conservative candidates, Mark Cramer and Peter Dombrowski, were support by C4KE, another Political action committee . They were joined by newcomers Susan Saam, and Barbara Valez. There were two independent candidates who self funded their own campaigns, one

246-625: A healthy diet are also recommended. Supportive care in severe cases includes treatment to relieve symptoms , fluid therapy , oxygen support and prone positioning , and medications or devices to support other affected vital organs. More severe cases may need treatment in hospital. In those with low oxygen levels, use of the glucocorticoid dexamethasone is recommended to reduce mortality. Noninvasive ventilation and, ultimately, admission to an intensive care unit for mechanical ventilation may be required to support breathing. Extracorporeal membrane oxygenation (ECMO) has been used to address

328-454: A school board ) may be elected, appointed by a political office holder, serve ex officio , or a combination of any of these. An independent school district is a legally separate body corporate and political . Most school districts operate as independent local governmental units with exclusive authority over K–12 public educational operations and policies. The extent of their control is set by state-level law. Litigation against school districts

410-615: A variant of concern (VoC) or a variant of interest (VoI). Many of these variants have shared the more infectious D614G . As of May 2023, the WHO had downgraded all variants of concern to previously circulating as these were no longer detected in new infections. Sub-lineages of the Omicron variant (BA.1 – BA.5) were considered separate VoCs by the WHO until they were downgraded in March 2023 as no longer widely circulating. As of 24 September 2024 ,

492-481: A "board of trustees," "board of education," "school committee," etc.. This body usually appoints or hires an experienced public school administrator to function as the district's superintendent of schools – a district's chief executive . The superintendent oversees daily operations, decisions and implements the policies of the board. The school board may also exercise a quasi-judicial function in serious employee or student discipline matters. School districts in

574-603: A certain degree comparable to a school district. Other arrangements are possible: certain types of special schools in North Rhine-Westphalia are run by the Landschaftsverbände . There also exist private schools , mostly funded by the States, but run by private entities like churches or foundations. In Italy , school districts were established in 1974 by the " Provvedimenti Delegati sulla scuola " ("Assigned Laws [to

656-493: A comprehensive international study. Such deaths include deaths due to healthcare capacity constraints and priorities, as well as reluctance to seek care (to avoid possible infection). Further research may help distinguish the proportions directly caused by COVID-19 from those caused by indirect consequences of the pandemic. In May 2022, the WHO estimated the number of excess deaths by the end of 2021 to be 14.9 million compared to 5.4 million reported COVID-19 deaths, with

738-561: A decline in property tax revenues during and after the Great Recession . By 2016 there were about 13,000 school districts, and the average student population was about 5,000. Although these terms can vary slightly between various states and regions, these are typical definitions for school district constitution: These terms may not appear in a district's name, even though the condition may apply. In England and Wales , school boards were established in 1870, and abolished in 1902, with

820-411: A decrease of 38,127 or 35%. Many states had passed laws facilitating school district consolidation. In 1951 the majority of the school districts in existence were rural school districts only providing elementary education, and some school districts did not operate schools but instead provided transportation to other schools. The Midwest had a large number of rural school districts. Previously areas of

902-590: A large number of people". During the COVID-19 pandemic, as with other pandemics, the meaning of this term has been challenged. The end of a pandemic or other epidemic only rarely involves the total disappearance of a disease, and historically, much less attention has been given to defining the ends of epidemics than their beginnings. The ends of particular epidemics have been defined in a variety of ways, differing according to academic field, and differently based on location and social group. An epidemic's end can be considered

These rates vary by a factor of ≈10,000 across the age groups. For comparison, the IFR for middle-aged adults is two orders of magnitude higher than the annualised risk of a fatal automobile accident and much higher than

1066-632: A minority of secondary schools , a few primary schools, and much further education . (Most schools are neither organized geographically nor publicly managed, although the Department of Education inspects and funds them and pays teachers' salaries.) Each ETB area comprises one or more local authority areas , with city or county councilors forming the bulk of the ETB board. The ETBs was formed in 2005 by amalgamating Vocational Education Committees established in 1930, also based on local government areas. In Hong Kong ,

1148-511: A notable role in the race. In particular, Bradley and Mc Gowan, who are both black, made social justice a central issue of their campaigns. Their ultimate election to the board was described by The Daily Herald as a success for equity voices in the district and was featured in The Herald's analysis of the impact of George Floyd's murder on the Chicago suburbs. Bradley told The Herald that he thought

1230-815: A random sample have consistently found that total infections considerably exceed the reported case counts. Many countries, early on, had official policies to not test those with only mild symptoms. The strongest risk factors for severe illness are obesity, complications of diabetes , anxiety disorders, and the total number of conditions. During the start of the COVID-19 pandemic it was not clear whether young people were less likely to be infected, or less likely to develop symptoms and be tested. A retrospective cohort study in China found that children and adults were just as likely to be infected. Among more thorough studies, preliminary results from 9 April 2020 found that in Gangelt ,

1312-450: A school system that is separate but similar to a town's or a county's powers. These include the power to enter contacts, use eminent domain , and to issue binding rules and regulations affecting school policies and operations. The power of school districts to tax and spend is generally more limited. For example, many school districts in New York state require a majority of voters living in

1394-706: A single school district." Noting that most modern school districts were formed by consolidating one-room school districts in the first seven decades of the 20th century, Fischel argues that "outside the South, these consolidations were consented to by local voters" who "preferred districts whose boundaries conformed to their everyday interactions rather than formal units of government" and that "[t]he South ended up with county-based school districts because segregation imposed diseconomies of scale on district operations and required larger land-area districts." In New York , most school districts are separate governmental units with

1476-457: A social phenomenon, not just a biological one. Time reported in March 2024 that expert opinions differ on whether or not COVID-19 is considered endemic or pandemic, and that the WHO continued to call the disease a pandemic on its website. During the initial outbreak in Wuhan , the virus and disease were commonly referred to as "coronavirus", "Wuhan coronavirus", "the coronavirus outbreak" and

1558-449: A state), most American school districts operate as independent local governmental units under a grant of authority and within geographic limits created by state law. The executive and legislative power over locally-controlled policies and operations of an independent school district are, in most cases, held by a school district's board of education. Depending on state law, members of a local board of education (often referred to informally as

1640-451: A test. Conversely, deaths of people who died from underlying conditions following a positive test may be included. Countries such as Belgium include deaths from suspected cases, including those without a test, thereby increasing counts. Official death counts have been claimed to underreport the actual death toll, because excess mortality (the number of deaths in a period compared to a long-term average) data show an increase in deaths that

Palatine High School was one of only 10 schools nationally to be named

1968-518: Is associated with COVID-19 and is reported in as many as 88% of cases. The disease is mainly transmitted via the respiratory route when people inhale droplets and small airborne particles (that form an aerosol ) that infected people exhale as they breathe, talk, cough, sneeze, or sing. Infected people are more likely to transmit COVID-19 when they are physically close to other non-infected individuals. However, infection can occur over longer distances, particularly indoors. SARS‑CoV‑2 belongs to

As of 2023 in most U.S. states, public school districts may lay taxes to fund their operations. In others, such as Maine , some school districts are able to lay taxes and others are not. Independent school districts often exercise authority over

It may take a mild course with few or no symptoms, resembling other common upper respiratory diseases such as the common cold . In 3–4% of cases (7.4% for those over age 65) symptoms are severe enough to cause hospitalisation. Mild cases typically recover within two weeks, while those with severe or critical diseases may take three to six weeks to recover. Among those who have died,

2214-439: Is intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), the virus that causes coronavirus disease 2019 ( COVID-19 ). Prior to the COVID-19 pandemic, an established body of knowledge existed about the structure and function of coronaviruses causing diseases like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). This knowledge accelerated

2296-485: Is not explained by COVID-19 deaths alone. Using such data, estimates of the true number of deaths from COVID-19 worldwide have included a range from 18.2 to 33.5 million (≈27.4 million) by 18 November 2023 by The Economist , as well as over 18.5 million by 1 April 2023 by the Institute for Health Metrics and Evaluation and ≈18.2 million (earlier) deaths between 1 January 2020, and 31 December 2021, by

2378-452: Is the ratio of deaths to diagnoses. This metric can be misleading because of the delay between symptom onset and death and because testing focuses on symptomatic individuals. Based on Johns Hopkins University statistics, the global CFR was 1.02 percent (6,881,955 deaths for 676,609,955 cases) as of 10 March 2023. The number varies by region and has generally declined over time. Several variants have been named by WHO and labelled as

2460-406: Is the seventh known coronavirus to infect people, after 229E , NL63 , OC43 , HKU1 , MERS-CoV , and the original SARS-CoV . The standard method of testing for presence of SARS-CoV-2 is a nucleic acid test , which detects the presence of viral RNA fragments. As these tests detect RNA but not infectious virus, its "ability to determine duration of infectivity of patients is limited." The test

2542-614: Is typically done on respiratory samples obtained by a nasopharyngeal swab ; however, a nasal swab or sputum sample may also be used. The WHO has published several testing protocols for the disease. Preventive measures to reduce the chances of infection include getting vaccinated, staying at home or spending more time outdoors, avoiding crowded places, keeping distance from others, wearing a mask in public, ventilating indoor spaces, managing potential exposure durations, washing hands with soap and water often and for at least twenty seconds, practising good respiratory hygiene, and avoiding touching

2870-773: The Midwest and West tend to cross municipal boundaries, while school districts in New England and the Mid-Atlantic regions tend to adhere to city, township, and/or county boundaries. As of 1951 school districts were independent governmental units in 26 states, while in 17 states there were mixes of independent school districts and school districts subordinate to other local governments. In nine states there were only school districts subordinate to local governments. In most Southern states, school systems operate either as an arm of county government or at least share coextensive boundaries with

Three common clusters of symptoms have been identified: one respiratory symptom cluster with cough, sputum , shortness of breath, and fever; a musculoskeletal symptom cluster with muscle and joint pain, headache, and fatigue; a cluster of digestive symptoms with abdominal pain, vomiting, and diarrhoea. In people without prior ear, nose, and throat disorders, loss of taste combined with loss of smell

5904-500: The state's counties. A 2010 study by economist William A. Fischel found that "two-thirds of medium-to-large American cities have boundaries that substantially overlap those of a single school district" with substantial regional and state variations in the degree of overlap, "ranging from nearly perfect congruence in New England , New Jersey, and Virginia, to hardly any in Illinois, Texas, and Florida." Older and more populous municipalities "tend to have boundaries that closely match those of

5986-411: The time from symptom onset to death has ranged from two to eight weeks. Prolonged prothrombin time and elevated C-reactive protein levels on admission to the hospital are associated with severe course of COVID-19 and with a transfer to intensive care units (ICU). Between 5% and 50% of COVID-19 patients experience long COVID , a condition characterised by long-term consequences persisting after

6068-694: The typical convalescence period of the disease. The most commonly reported clinical presentations are fatigue and memory problems, as well as malaise , headaches, shortness of breath , loss of smell, muscle weakness , low fever and cognitive dysfunction . Many countries attempted to slow or stop the spread of COVID-19 by recommending, mandating or prohibiting behaviour changes, while others relied primarily on providing information. Measures ranged from public advisories to stringent lockdowns. Outbreak control strategies are divided into elimination and mitigation. Experts differentiate between elimination strategies (known as " zero-COVID ") that aim to completely stop

A more systematic naming scheme reflects the variant's PANGO lineage (e.g., Omicron 's lineage is B.1.1.529) and is used for other variants. SARS-CoV-2 is a virus closely related to bat coronaviruses , pangolin coronaviruses, and SARS-CoV . The first known outbreak (the 2019–2020 COVID-19 outbreak in mainland China ) started in Wuhan , Hubei, China, in December 2019. Many early cases were linked to people who had visited

Official "case" counts refer to the number of people who have been tested for COVID-19 and whose test has been confirmed positive according to official protocols whether or not they experienced symptomatic disease. Due to the effect of sampling bias , studies which obtain a more accurate number by extrapolating from

According to a June 2022 study, COVID-19 vaccines prevented an additional 14.4 million to 19.8 million deaths in 185 countries and territories from 8 December 2020 to 8 December 2021. On 8 November 2022, the first recombinant protein-based COVID-19 vaccine (Novavax's booster Nuvaxovid ) was authorised for use in adults in the United Kingdom.
