Of course, Slack is not Microsoft Teams only competitor. Microsoft has also received heat for aggressively pushing Teams to all users, even non-365 subscribers. Slack has filed an EU antitrust complaint over this, arguing that it is a misuse of platform power. It natively integrates with Word, PowerPoint and Microsoft 365, but Slack has spent years building a library of app plugins, which surpassed Teams in quantity until recently.įor businesses already subscribed to Microsoft 365 Business, Teams is a free add-on, instead of a separate bill. They are still SARS-CoV-2, but may act differently.Microsoft Teams key advantage over competitors is its deep integration with Office 365. Scientists call the viruses with these changes “variants”. Sometimes branches of that tree have different attributes that change how fast the virus spreads, or the severity of illness it causes, or the effectiveness of treatments against it. Just as a family has a family tree, the SARS-CoV-2 virus can be similarly mapped out. Because of the importance of this specific part of the virus, scientists who sequence the virus for research constantly monitor mutations causing changes to the spike protein through a process called genomic surveillance.Īs genetic changes to the virus happen over time, the SARS-CoV-2 virus begins to form genetic lineages. Some antibodies can protect you from SARS-CoV-2 by targeting these spike proteins. The spike protein is the part of the virus that attaches to a human cell to infect it, allowing it to replicate inside of the cell and spread to other cells.
These spike proteins are important to the biology of this virus. The word corona means crown and refers to the appearance that coronaviruses get from the spike proteins sticking out of them. Like many other respiratory viruses, coronaviruses spread quickly through droplets that you project out of your mouth or nose when you breathe, cough, sneeze, or speak. It is part of the coronavirus family, which include common viruses that cause a variety of diseases from head or chest colds to more severe (but more rare) diseases like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). About SARS-CoV-2, the virus that causes COVID-19ĬOVID-19 is caused by a virus called SARS-CoV-2.
