"Calm, calm down. The (COVID-19) virus has become rampant. Everyone here is anxious."

"The big mistake in the U.S. and Europe, in my opinion, is that people aren't wearing masks. This virus is transmitted by droplets and close contact. Droplets play a very important role − you've got to wear a mask, because when you speak, there are always droplets coming out of your mouth. Many people have asymptomatic or presymptomatic infections. If they are wearing face masks, it can prevent droplets that carry the virus from escaping and infecting others."

"For those that were originally vaccinated with vaccine A and then receive a vaccine B booster, the results are better than those vaccinated under an 'AA' or 'BB' plan."
