Why do these rich countries lack masks when the price of masks sold in Europe is high?            
A cruel fact lies ahead. Europe and the United States are beginning to stand in the center of the epidemic.           
 According to the data, at present, the number of newly confirmed cases in many European and American countries has reached more than 3400 every day. A novel coronavirus pneumonia confirmed by the World Health Organization (WHO) released 460 thousand cases, and the number of confirmed cases continued to grow. Among them, the Americas and Europe have the most new cases in 24 hours, while the United States has become the first country in the world with more than 100000 newly confirmed cases.            
Under the epidemic situation, the gap of many countries' protective materials is shocking, which also leads to the price of epidemic prevention materials soaring.
