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...

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. ...
