What you need to know about
Coronavirus is a common virus that can infect your upper neck, sinuses, or nose. Most coronaviruses do not pose a threat.
Following an epidemic in China in December 2019, the World Health Organization recognised SARS-CoV-2 as a novel Covid-19 Coronavirus in the early months of 2020. The epidemic spread fast around the globe.
SARS-CoV-2-transmitted COVID-19 is a disease that can result in what medical professionals refer to as a respiratory tract infection. It can impact either your lower respiratory tract or upper respiratory tract (sinuses, nose, and throat) (windpipe and lungs).
Similar to other coronaviruses, it spreads mostly through human contact. Infections can be dangerous or benign.
One of seven coronavirus types, SARS-CoV-2 is responsible for serious illnesses such as the Middle East respiratory syndrome (MERS) and sudden acute respiratory syndrome (SARS). The other coronaviruses don’t pose a substantial threat to normal healthy people, but they do cause the majority of the colds that we experience each year.
Does SARS-CoV-2 have several strains?
Two strains were identified in an early Chinese study of 103 COVID-19 cases, and they were designated L and S. Although the L type was more prevalent in the early phases of the pandemic, the S type is older. Scientists are still figuring out what it all means, but they believe one may contribute to more incidences of illness than the other.
A virus may also alter or evolve as it spreads among humans, as this virus has done. There are a number of varieties that are now circulating, some of which are proving to be both more contagious and more lethal than the original virus.
Throughout the epidemic, researchers have closely monitored variations like:
How long will the Covid-19 Coronavirus persist?
It is impossible to predict how long the pandemic will last. There are other reasons, such as public initiatives to halt the spread, research efforts to better understand the virus, search efforts for a cure, and the effectiveness of vaccines.
