What is the new Covid variant?
A coronavirus variant known as “mu” or “B.1.621” was designated by the World Health Organization as a “variant of interest” earlier this week and will be monitored by the global health body as cases continue to emerge across parts of the world. It is the fifth variant of interest currently being monitored by the WHO.
What is the difference SARS-CoV-2 and MERS-CoV?
SARS-CoV-2 is a novel coronavirus identified as the cause of coronavirus disease 2019 (COVID-19) that began in Wuhan, China in late 2019 and spread worldwide. MERS-CoV was identified in 2012 as the cause of Middle East respiratory syndrome (MERS).
Can people who recover from COVID-19 be re-infected with SARS-CoV-2?
See full answerCDC is aware of recent reports indicating that persons who were previously diagnosed with COVID-19 can be re-infected. These reports can understandably cause concern. The immune response, including duration of immunity, to SARS-CoV-2 infection is not yet understood. Based on what we know from other viruses, including common human coronaviruses, some reinfections are expected. Ongoing COVID-19 studies will help establish the frequency and severity of reinfection and who might be at higher risk for reinfection. At this time, whether you have had COVID-19 or not, the best ways to prevent infection are to wear a mask in public places, stay at least 6 feet away from other people, frequently wash your hands with soap and water for at least 20 seconds, and avoid crowds and confined spaces.

Can COVID-19 be transmitted through saliva?
The study, published in the journal Nature Medicine, shows that SARS-CoV-2, which is the coronavirus that causes COVID-19, can actively infect cells that line the mouth and salivary glands.
What is the Lambda Variant?
Lambda was classified as a variant of interest at the global level by the World Health Organization (WHO) on 15 June 2021. As a variant of interest, the WHO considers Lambda to have mutations with established, or suspected, implications for its transmissibility and severity, and has been detected in multiple countries.
What is a variant?
Viruses constantly change through mutation. A variant has one or more mutations that differentiate it from other variants in circulation. As expected, multiple variants of SARS-CoV-2 have been documented in the United States and globally throughout this pandemic.
