The Sars-CovV-2 pandemic

SARS-CoV-2, a previously undiscovered coronavirus, is found in patients in Wuhan, China, in late 2019. The novel virus, which causes the potentially fatal respiratory disease COVID-19, sweeps the world. On March 11, 2020, the World Health Organization declares the outbreak a pandemic. Governments and health authorities across the globe use emergency physical distancing, quarantining, hand-washing, and masking measures to mitigate the spread of infection. By October 2020, COVID-19 has infected more than 38 million individuals worldwide and has claimed the lives of more than one million.
