Understanding Coronavirus Infection and Its Impact on Health

How does coronavirus enter the body, and why does it become fatal for some compared to just a cough or fever for others?<br />U.S. exports of surgical masks, ventilators and other personal protective gear to China skyrocketed in January and February, when the coronavirus was wreaking havoc in the country where it began and as U.S. intelligence agencies warned it would soon spread.<br /><br />American companies sold more than $17.5 million worth of face masks, more than $13.6 million in surgical garments and more than $27.2 million in ventilators to China during the first two months of the year, far exceeding that of any other similar period in the past decade, according to the most recent foreign trade data available from the U.S. Census Bureau.
