Strike Debt is a decentralized debt resistance collective. Formed as an offshoot from Occupy Wall Street and the Occupy movement , it is similar to Occupy Sandy in practicing " mutual aid as direct action ". In 2012, they published the Debt Resistors Operations Manual.
67-438: Rolling Jubilee is a Strike Debt initiative that purchases and forgives monetary debt on the secondary market . Bank loans deemed unlikely to be repaid are reclassified as risky. Banks looking to recuperate the debt's little outstanding worth resell these portfolios on the secondary market at a fraction of their original worth. This type of high-risk debt is normally purchased by debt collectors who believe they can recover more from

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
201-615: 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 ,

The secondary market can be for a variety of assets, that can vary from stocks to loans, from fragmented to centralized, and from illiquid to very liquid. The major stock exchanges are the most visible example of liquid secondary markets—in this case, for stocks of publicly traded companies. Exchanges such as
469-493: 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
536-590: 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
737-815: 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 ,

The group supported the "Corinthian 15" students who sought full debt relief as their school, the for-profit Corinthian Colleges, was being dismantled while under multiple investigations and lawsuits. Following Corinthian's 2015 bankruptcy, the Debt Collective helped students file thousands of loan forgiveness claims, exercising a U.S. Department of Education escape clause in which debtors misled by their college can ask for forgiveness. During

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

Similarly, secondary markets can be said to exist in some real estate contexts as well ( e.g. , ownership shares of time-share vacation homes are bought and sold outside of the official exchange set up by the timeshare issuers). These have very similar functions as secondary stock and bond markets in allowing for speculation, providing liquidity, and financing through securitization . This facilitates liquidity and marketability of

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,
