A Review of COVID-19
It has been just four months since the first case of coronavirus was reported in Wuhan, China. The 2019– 2020 coronavirus pandemic is an ongoing pandemic of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome . Starting from December 2019, the virus has hopped borders, affecting more than 500,000 marks. To date, there are more than 592,000 confirmed cases of the disease worldwide. Although the vast majority of cases initially originated in China, it is currently the United States with the most reported cases. Italy, Spain, Germany, France, Iran, the United Kingdom, and Switzerland are among the most affected countries. Experts believe the actual number of 2019-nCoV cases may be higher than reported because many patients have been found asymptomatic, while most countries are struggling with inadequate testing. The global mortality rate for COVID-19 is currently 3.4%, which is much higher than the seasonal flu, with only 0.1% of those affected.
