[246] Trump's approval rating increased from 44% to 49% in Gallup polls,[247] but it fell to 43% by mid-April. [38][39], The closer people interact, and the longer they interact, the more likely they are to transmit COVID-19. [255] Firm lower limits of IFRs have been established in a number of locations such as New York City and Bergamo in Italy since the IFR cannot be less than the population fatality rate. [126] This is done by slowing the infection rate to decrease the risk of health services being overwhelmed, allowing for better treatment of current cases, and delaying additional cases until effective treatments or a vaccine become available. Some states like Texas and Arizona opted to proceed with reopening without adequate contact tracing programs in place. Theoretically the usage of angiotensin receptor blockers (ARB) and ACE inhibitors upregulating ACE2 expression might increase morbidity with COVID-19, though animal data suggest some potential protective effect of ARB.

[222], Some early studies suggest that that 10 to 20% of people with COVID-19 will experience symptoms lasting longer than a month. [331] In early and mid-January 2020, the virus spread to other Chinese provinces, helped by the Chinese New Year migration and Wuhan being a transport hub and major rail interchange. They included hotels, college dormitories, and larger open buildings, which were converted into temporary hospitals. [260], Early reviews of epidemiologic data showed gendered impact of the pandemic and a higher mortality rate in men in China and Italy. Several testing methods have been developed to diagnose the disease. [69] SARS-CoV-2 could cause respiratory failure through affecting the brain stem as other coronaviruses have been found to invade the CNS. [224], Some of these facilities had ICUs for COVID-19 patients, while others served non-coronavirus patients to allow established hospitals to concentrate on the pandemic. Nine tested positive for coronavirus", "When Did COVID-19 Arrive and Could We Have Spotted It Earlier? [97][111] Characteristic imaging features on chest radiographs and computed tomography (CT) of people who are symptomatic include asymmetric peripheral ground-glass opacities without pleural effusions. This number consisted of 2,672 cases of the B.1.1.7 variant, 68 cases of the 501.V2 variant, and 13 cases of the P.1 variant. [363] As of November 2020[update], more than 200 possible treatments had been studied in humans so far. Jump to navigation Jump to search. The standard diagnostic method is by detection of the virus' nucleic acid by real-time reverse transcription polymerase chain reaction (rRT-PCR), transcription-mediated amplification (TMA), or by loop-mediated isothermal amplification from a nasopharyngeal swab. Hypertens Res. The theory correctly stated that asymptomatic people could "easily" transmit the virus, a belief that was presented as outside medical consensus at the time of the briefing. [165], There is no specific, effective treatment or cure for coronavirus disease 2019 (COVID-19), the disease caused by the SARS-CoV-2 virus. Image Plummets Internationally as Most Say Country Has Handled Coronavirus Badly", "Could the Pandemic Wind Up Fixing What's Broken About Work in America? The name was coined by June Almeida and David Tyrrell who first observed and studied human coronaviruses. [66] On April 11, the U.S. death toll became the highest in the world when the number of deaths reached 20,000, surpassing that of Italy. [361] There has been a great deal of COVID-19 research, involving accelerated research processes and publishing shortcuts to meet the global demand. They range from fatigue, a cough and shortness of breath, to inflammation and injury of major organs – including the lungs and heart, and also neurological and psychologic effects. [75] An acute cardiac injury was found in 12% of infected people admitted to the hospital in Wuhan, China,[76] and is more frequent in severe disease. [95] The WHO has published several testing protocols for the disease. Other people are infected if the virus gets into their mouth, nose or eyes. [Structure of SARS-CoV-2 and treatment of COVID-19]. [96], In spite of recommendations by the government not to travel, over two million people ended up flying on airlines during the Thanksgiving period. J Med Internet Res. [90], The virus' effect on ACE2 cell surfaces leads to leukocytic infiltration, increased blood vessel permeability, alveolar wall permeability, as well as decreased secretion of lung surfactants. [9] Older people are more likely to have severe symptoms.

[213][214][215][216] Approximately 20–30% of people who present with COVID-19 have elevated liver enzymes, reflecting liver injury. Why did Britain fail to act? In early March, President Trump directed the FDA to test certain medications to discover if they had the potential to treat COVID-19 patients. [190][191] A majority of those who were admitted to hospital with severe disease report long-term problems including fatigue and shortness of breath. The use of face masks or coverings has been recommended in public settings to minimise the risk of transmissions. Public health officials in California claim that most of the functionality could be duplicated by using text, chat, email and phone communications.[140]. [392] Dexamethasone can be taken by mouth or given as an injection or infusion (drip) into a vein. [314], From 2019 to the first half of 2020, in the United States, the life expectancy of a white person decreased 0.8 years; a Hispanic person, 1.9 years; and a Black person, 2.7 years. It was first isolated from three people with pneumonia connected to the cluster of acute respiratory illness cases in Wuhan. [207], Uncontrolled community spread led some medical facilities to refuse new patients or start transferring patients out. doi: 10.1038/s41440-020-0455-8. Closer distances can involve larger droplets (which fall to the ground) and aerosols, whereas longer distances only involve aerosols. Health officials are also worried that low-income communities will fall further behind in contact tracing efforts which "may also be hobbled by long-standing distrust among minorities of public health officials". [130], Social distancing (also known as physical distancing) includes infection control actions intended to slow the spread of the disease by minimising close contact between individuals. [243], Political analysts anticipated that the pandemic would negatively affect Trump's chances of re-election. [317], The pandemic prompted calls from voting rights groups and some Democratic Party leaders to expand mail-in voting, while Republican leaders generally opposed the change. [58] Since March 19, the State Department has advised U.S. citizens to avoid all international travel. [244][245] In March 2020, when social distancing practices began, the governors of many states experienced sharp gains in approval ratings. [69], By May 27, less than four months after the pandemic reached the U.S., 100,000 Americans had died with COVID-19. [384], In June, initial results from the randomised RECOVERY Trial in the United Kingdom showed that dexamethasone reduced mortality by one third for people who are critically ill on ventilators and one fifth for those receiving supplemental oxygen. The 501Y.V2 Variant, which has the same N501Y mutation, arose independently in South Africa. [95][96] Along with laboratory testing, chest CT scans may be helpful to diagnose COVID-19 in individuals with a high clinical suspicion of infection. [204][205] Genetic screening is able to detect interferon effector genes. [81][82][83], Another common cause of death is complications related to the kidneys.

However, federal agencies, including the Food and Drug Administration and the Federal Emergency Management Agency, as well as the United States Department of Health and Human Services were pushing the states to use the BGI testing kits, despite such warnings. [103], A number of laboratories and companies have developed serological tests, which detect antibodies produced by the body in response to infection. [95], The standard methods of testing for presence of SARS-CoV-2 are nucleic acid tests,[95][98] which detects the presence of viral RNA fragments. Responding to Democratic proposals for nationwide mail-in voting as part of a coronavirus relief law, President Trump said, "you'd never have a Republican elected in this country again" despite evidence the change would not favor any particular group. [231] Social distancing of soldiers is in place during training, assemblies,[232] and transport between locations.

[218][219] Following the infection, children may develop paediatric multisystem inflammatory syndrome, which has symptoms similar to Kawasaki disease, which can be fatal. [45] There is a major role of "super-spreading events", where many people are infected by one person. [257], Beginning in mid-April 2020, there were protests in several U.S. states against government-imposed lockdowns in response to the COVID-19 pandemic in the United States. WHO declared the outbreak a Public Health Emergency of International Concern on 30 January, and a pandemic on 11 March. [240] In February, similar numbers of Democrats and Republicans believed COVID-19 was "a real threat": 70% and 72%, respectively.

However, the aggravation of local inflammation causes a cytokine storm eventually leading to a systemic inflammatory response syndrome. [128] The final report was released on February 28. [323] On 30 December, a test report addressed to Wuhan Central Hospital, from company CapitalBio Medlab, stated an erroneous positive result for SARS, causing a group of doctors at Wuhan Central Hospital to alert their colleagues and relevant hospital authorities of the result. [111], Also on January 6, supporters of President Trump stormed the United States Capitol building. For diseases caused by coronaviruses, see, Effect on other diseases and the pharmacy trade, "Close contact" is variously defined, including as being within ~1.8 metres (six feet) and face to face for a cumulative total of 15 minutes by the US, Oran, Daniel P., and Eric J. Topol. Transmission may be decreased indoors with well maintained heating and ventilation systems to maintain good air circulation and increase the use of outdoor air. [308] By July, rural communities with populations less than 50,000 had some of the highest rates of new daily cases per capita. [118] On January 22, the U.S. passed 25 million cases, with one of every 13 Americans testing positive for COVID-19. [75] ACE2 receptors are highly expressed in the heart and are involved in heart function. [30] Of four studies published in September 2020, three found clear disparities due to race and the fourth found slightly better survival rates for Hispanics and Blacks. [41] Also, the first report of a COVID-19 case in the U.S. was reported. Can it work in the U.S.? [313] Additionally, a study published by the New England Journal of Medicine in July 2020 revealed that the effect of stress and weathering on minority groups decreases their stamina against COVID. Total confirmed cases of COVID-19 per million people[243], Total confirmed deaths due to COVID-19 per million people[244], A key metric in gauging the severity of COVID-19 is the infection fatality rate (IFR), also referred to as the infection fatality ratio or infection fatality risk. Please update this article to reflect recent events or newly available information. [114][116] Four members of Congress have since tested positive due to the exposure. "[108], Chest CT scans may be helpful to diagnose COVID-19 in individuals with a high clinical suspicion of infection but are not recommended for routine screening. [97][109] Bilateral multilobar ground-glass opacities with a peripheral, asymmetric, and posterior distribution are common in early infection. [144] One of Didier's COVID-19 studies was later retracted by the International Journal of Antimicrobial Agents. [358], International research on vaccines and medicines in COVID-19 is underway by government organisations, academic groups, and industry researchers. [125], On January 28, the CDC updated its China travel recommendations to level 3, its highest alert. [255][256] Controlling for relevant factors, Republican governors were slower to implement social distance policies than Democratic governors. [315] In May 2020, George Gao, the director of the CDC, said animal samples collected from the seafood market had tested negative for the virus, indicating that the market was the site of an early superspreading event, but it was not the site of the initial outbreak. So the masks with exhalation valve are not for the infected wearers, and are not reliable to stop the pandemic in a large scale.
