Get a deeper understanding of the COVID-19 pandemic and learn about the virus structure and viral properties of the SARS-CoV-2 virus. In a world where millions of people live under the threat of COVID-19 it is of vital importance to gain a better understanding of how the virus actually works.
SARS-CoV-2 is a new type of coronavirus that has never been seen in humans before. It is believed that the coronavirus made the jump from animals to humans at a live animal market in Wuhan, China in late 2019. While bats are the originally source and the natural host, the virus is now spreading from human to human and causing COVID-19 (the coronavirus disease).
The most known way of how COVID-19 spreads between humans, is through small droplets carrying thousands of virus particles being let out when coughing, sneezing, or simply when speaking. The droplets travel to others within a certain distance through the air.
The time that passes from the moment a virus enters the body until signs and symptoms of the disease start showing, is known as the incubation period. It can vary a lot from person to person, but scientists believe that the incubation period for COVID-19 is sometime between 2-14 days.
