SARS was the ?rst new plague of the twenty-?rst century. Within months, it spread worldwide from its “birthplace” in Guangdong Province, China, affecting over 8,000 people in 25 countries and territories across ?ve continents. Coronaviruses, including the pneumonia-causing novel coronavirus currently known as SARS-CoV-2, are enveloped, nonsegmented, positive-sense RNA viruses. Is it safe for a man to have sex after recovering from COVID-19? Coronaviruses (CoVs), enveloped positive-sense RNA viruses, are characterized by club-like spikes that project from their surface, an unusually large RNA genome, and a unique replication strategy. However, there are a few differences between the two molecules. It was updated on March 2, 2021, to include information about the Johnson & Johnson vaccine, and on August 18, 2021, to include a personal note from Dr. Lawler and further clarify some parts of the article that were causing confusion. Virology. What is Coronavirus? An unresolved issue of SARS-CoV-2 disease is that patients often remain positive for viral RNA as detected by PCR many weeks after the initial infection in the absence of evidence for viral replication. 1988;62:4280–4287. Covid-19 stands for "coronavirus disease 2019." In the past few decades, as scientists came to realize that genetic material is largely regulated by the RNA it encodes, that most of our DNA produces RNA, and that RNA is not only a target but also a tool for disease therapies, "the RNA research world has exploded," Maquat says.
