  2. SARS‑CoV‑2 is a virus of the species severe acute respiratory syndrome–related coronavirus (SARSr-CoV), related to the SARS-CoV-1 virus that caused the 2002–2004 SARS outbreak. [2] [16] Available evidence indicates that it is most likely of zoonotic origins and has close genetic similarity to bat coronaviruses, suggesting it emerged ...

  3. The SARSr-CoV species is a member of the genus Betacoronavirus and of the subgenus Sarbecovirus ( SAR S Be ta co rona virus ). Two strains of the virus have caused outbreaks of severe respiratory diseases in humans: severe acute respiratory syndrome coronavirus 1 (SARS-CoV or SARS-CoV-1), which caused the 2002–2004 outbreak of severe acute respiratory syndrome (SARS), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is causing the ongoing pandemic of COVID-19.

    The genetic material of this virus showed many similarities to SARS-CoV (79.5%) and bat coronaviruses (96%). This means the virus may have originally come from bats. Scientists did more experiments that showed the virus probably went from bats to an intermediate host, meaning another animal in between bats and humans. The viruses in that other anim...

    In early February 2020, the International Committee on the Taxonomy of Viruses' Coronavirus Study Group gave SARS-CoV-2 its official name, for sudden acute respiratory syndrome coronavirus number two. Before that, people called the virus "2019-nCoV," for "novel (new) coronavirus that appeared in 2019." The study group chose this name because the ne...

    In February 2020, the World Health Organization announced they had chosen a name for the disease caused by SARS-CoV-2: COVID-19. "Covi" for "coronavirus," "D" for "disease," and "19" for the year 2019. They said they did not want the name to have any person, place, or animal in it, like "Wuhan," or “pangolin,” because then people might blame the di...

    According to the United States Centers for Disease Control and Prevention, COVID-19 makes people feel sick in different ways, but it usually affects the lungs. People usually cough and have difficulty breathing. They often also have a fever, chills, headache, pain in their muscles, or trouble tasting or smelling things. According to an April 2020 s...

    The SARS-CoV-2 virus looks like a round ball with spikes all around it. There are four parts to the virus: the spikes, a membrane, an envelope, and the virus' genetic material, or ribonucleic acid (RNA) Each of these four parts is a different protein molecule. The spikes, membrane, and envelope are together called the viral envelope, or outer layer...

    In early 2020, some people began to think that the SARS-CoV-2 may have been made on purpose in a laboratory at the Wuhan Institute of Virology and released in Wuhan like a weapon. When the leader of Iran, Ayatollah Khamenei, said that he did not want the United Statesto help his country against coronavirus, he named the idea that Americans had made...

    There are no fixed cures for the treatment of COVID-19, but there are various drugs that have been approved for use such as Hydroxychloroquine and Remdesivir which are detailed below. Other antiviral drugs, interferon therapy and combination of anti-viral and interferons are also being experimented on to get the best possible outcome for patients. ...

  4. Severe acute respiratory syndrome ( SARS) was an atypical pneumonia. It started in November 2002 in Guangdong Province, in the city of Foshan, of the People's Republic of China. The disease was caused by the SARS coronavirus (SARS CoV), a new coronavirus. It was also a part-time STD, it can be spread through both sexual and casual contact.

  5. SARS-CoV-2 (Abkürzung für englisch severe acute respiratory syndrome coronavirus type 2 ‚ [3] Schweres-akutes-Atemwegssyndrom-Coronavirus Typ 2) ist ein Betacoronavirus, das nach dem erstmaligen Nachweis zunächst auch als neuartiges Coronavirus oder nur als Coronavirus bezeichnet wurde. Es ist mit dem Betacoronavirus SARS-CoV-1 verwandt ...

  6. Sars-cov-2 eller SARS-CoV-2 ( Severe acute respiratory syndrome coronavirus 2, som ungefär betyder "allvarligt akut respiratoriskt syndrom-coronavirus 2") är ett för människa, och olika djurarter, smittsamt coronavirus som orsakar sjukdomen covid-19 och som givit upphov till coronaviruspandemin 2019–2021. Viruset, som först upptäcktes i ...
