[ti:Can Tents at Restaurants Prevent Coronavirus Infections?] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.04]Some restaurants are providing plastic tents [00:04.52]so people can stay separated from each other while they eat. [00:10.56]But are these tents a safe way [00:13.76]to eat out during the coronavirus health crisis? [00:19.04]Health experts say outdoor tent [00:22.60]s are a little safer than eating inside. [00:26.40]But, not all tents are equal, they add. [00:31.92]Many restaurants are putting up single tents, [00:35.88]and other outdoor structures that let people [00:40.04]who are eating together avoid being indoors. [00:45.24]The coronavirus spreads more easily when people are indoors. [00:52.48]Experts say the tents should have good air circulation. [00:59.08]A tent with four walls and a roof, for example, [01:03.40]might not have better air circulation than an indoor dining room. [01:10.68]“The more airflow through the structure, the better it is,” [01:15.52]says Dr. Isaac Weisfuse. [01:19.12]He is a public health expert at Cornell University. [01:25.24]Tents are a creative answer, but should not be shared with people [01:31.24]you do not see every day. [01:33.76]That advice is from Craig Hedberg. [01:37.80]He is a professor at the University of Minnesota School of Public Health. [01:45.76]“If it’s keeping you from being in a common airspace with other people, [01:51.48]then that’s a good thing,” he added. [01:56.00]Aubree Gordon is an associate professor [01:59.72]at the University of Michigan School of Public Health. [02:05.36]She said tents should be cleaned and left open [02:09.84]for at least 20 minutes after they are used by one group of people. [02:17.08]She also said servers should not directly serve food [02:22.08]but should leave it outside the tent. [02:25.96]This would decrease the risk of infection. [02:29.88]Tents are a way that restaurants can serve people food [02:35.32]when many areas have restrictions [02:38.32]barring people from gathering inside eating places. [02:44.20]But using them means additional costs. [02:49.28]In Detroit, Lumen restaurant asks $30 for each person [02:55.92]for a heated structure for two hours. [03:00.60]Lumen has larger tents that can seat six people. [03:06.48]The group must buy at least $300 worth of food. [03:13.00]Each time the tent is emptied, the structure is cleaned [03:17.80]with sanitizer and aired out for 30 minutes, [03:22.48]said Gabby Milton, who is the restaurant’s managing partner.
