First, continued passenger input. Although the United States banned Chinese entry as early as February 1 and foreigners who have been to China in the past 14 days, there were 140,000 Italians and approximately 1.74 million from Schengen countries Passengers arrive in the United States;

Second, large-scale personnel gatherings, there are many large-scale gatherings in the last week of February, which has a significant effect on the spread of the epidemic, including the carnival held in Louisiana by more than 1 million people. ;

Third, there is a lack of protective measures. It was not until April 3 that the US Centers for Disease Control issued guidelines that required cloth masks to be worn in public places to reduce transmission.

Fourth, inadequate testing, the new crown epidemic and the flu season overlap, resulting in the failure to distinguish the new crown epidemic. In addition, the limited testing scale in the United States failed to detect all cases.

To prevent the spread of COVID-19:
• Clean your hands often. Use soap and water, or an alcohol-based hand rub.
• Maintain a safe distance from anyone who is coughing or sneezing.
• Don’t touch your eyes, nose or mouth.
• Cover your nose and mouth with your bent elbow or a tissue when you cough or sneeze.
• Stay home if you feel unwell.
• If you have a fever, a cough, and difficulty breathing, seek medical attention. Call in advance.
• Follow the directions of your local health authority.
• Avoiding unneeded visits to medical facilities allows healthcare systems to operate more effectively, therefore protecting you and others.
