[00:00.04]The COVID-19 pandemic [00:02.72]is affecting Thanksgiving holiday plans [00:05.88]for many American families. [00:09.36]The Associated Press reports that coronavirus cases [00:14.20]are rising at a worrying speed across the United States. [00:20.56]The Johns Hopkins Coronavirus Resource Center says [00:25.44]the virus has killed over 250,000 people nationwide. [00:32.88]Many people are getting infected every day. [00:37.36]The U.S. Centers for Disease Control and Prevention (CDC) last week [00:42.64]released guidelines on the safest way to celebrate Thanksgiving. [00:48.12]The CDC is advising Americans not to travel over the holiday this year. [00:56.20]And it is urging them against spending time with people [01:01.16]from outside their immediate household. [01:05.60]The warning is some of the firmest guidance yet from the CDC [01:10.76]on how to limit the spread of the virus. [01:14.96]The health care system is under great pressure in many communities. [01:20.32]Sick patients are filling up hospital beds, [01:24.48]while some medical workers are getting sick themselves. [01:30.68]Holiday celebrations seem like a perfect way to spread the coronavirus. [01:37.92]In some families, people come together from different parts of the country. [01:44.12]Holiday gatherings usually include many generations [01:48.60]-- from young children to their grandparents. [01:53.24]Older adults may have health problems [01:56.12]such as diabetes, obesity, or heart disease. [02:02.20]The CDC website says that these conditions raise the risk [02:07.40]"of severe illness from the virus that causes COVID-19." [02:13.52]And people may not know they are infected with the coronavirus. [02:19.24]Experts note that students returning home from college [02:23.32]may carry the virus and not know it. [02:27.12]Younger people are more likely to have asymptomatic infections. [02:33.76]Experts have been advising people to limit their contact [02:38.04]to a single group of people, called a "bubble." [02:42.96]Less contact with people outside the bubble [02:46.32]means a lower risk of infection. [02:50.72]Thanksgiving usually [02:52.52]is the busiest travel period of the year in the United States. [02:56.92]Some 50 million Americans travel 80 or more kilometers [03:02.44]to share a meal with friends and family. [03:06.40]This information comes from AAA, an automotive and travel group. [03:13.20]Crowded buses, trains, and waiting rooms with poor ventilation, or airflow, [03:20.00]are places where the virus can easily spread. [03:25.12]The longer the trip, the higher the risk. [03:28.60]Airplane travel is less clear. [03:33.32]The dangers begin before getting on a plane, train or bus, [03:38.08]notes Cameron Wolfe, a professor at the Duke University School of Medicine. [03:45.96]Gathering family members and friends indoors [03:49.64]for long periods of time raises the chances for the virus to spread. [03:56.64]This is happening already, notes Doctor Anthony Fauci, [04:00.92]head of the National Institute of Allergy and Infectious Diseases. [04:08.04]"If you look around the country now, many of the infections [04:12.12]are in small family-and-friend gatherings [04:15.52]such as dinner parties and small social gatherings," he said. [04:21.60]Fauci explained that the danger is when one person [04:25.52]who is asymptomatic and infected gets others infected. [04:32.36]The U.S. Centers for Disease Control and Prevention says [04:36.84]that about 40 percent of those infected do not have clear symptoms [04:42.80]but can still spread the virus. [04:47.32]Getting tested for the coronavirus before traveling might be helpful. [04:52.92]However, experts urge caution. [04:56.40]Most rapid tests do not work well [04:59.68]for people who are not showing signs of the disease, they note. [05:04.20]Even the best tests can miss an early infection. [05:09.88]And people can get infected in the time between getting tested [05:14.80]and when they arrive for holiday celebrations. [05:18.56]I'm Anna Matteo. 如果您也喜欢 恒星英语学习网 www.hxen.com 请与您的朋友分享...
