- Experts say a person who has recovered from COVID-19 should wait at least 10 days from the date of a positive test before going out in public again.
- They note that recovery periods can vary from person to person in terms of length and how people feel.
- 专家说，即使康复后，人们仍然应该戴口罩并在公共场合观察身体远处。

It’s a question being asked in homes across the United States as well as the rest of the world: When is it safe again to be near someone who’s had新冠肺炎？
像其他传染病一样，恢复时间可能因人而异，但专家建议人们遵循
“It is now generally thought that about 10 days after the test that’s positive, if you have no symptoms, no fever, you can be considered no longer contagious,”Dr. William Schaffner田纳西州范德比尔特大学的传染病专家告诉Healthline。雷竞技app官网
疾病预防控制中心说，从库维德（Covid）恢复的人与他人周围康复的人有一个安全的时间取决于许多因素。
那些患有19岁和症状的人，自从症状发作至少24小时而没有发烧而没有使用发烧药物的情况下，就可以至少在其他人身边。他们还应该等到症状改善。
对于那些测试阳性但没有症状的人，他们可以在阳性测试后10天与其他人在一起。
People who are immunocompromised should talk to their doctor about whether they need to stay isolated for more than 10 days. Those in this category can be with others after receiving two consecutive negative test results at least 24 hours apart.
专家说，康复很复杂，并不一定意味着一个人感觉完全很好。
“The symptoms can last quite some time so it’s not complete recovery, it’s resolution of fever without the use of fever-reducing medications with progressive improvement or resolution of other symptoms,”Dean Blumberg博士加利福尼亚大学戴维斯大学儿童医院的小儿传染病负责人告诉Healthline。雷竞技app官网
“Just like with many other infectious diseases, some people recover very quickly and aren’t infectious to others and then in others the viral replication might linger on,” Blumberg said. “In general, I would follow these guidelines as a starting point for when you would consider going out but if you are still significantly symptomatic… for example having coughing or sneezing, it would be uncomfortable being out in public, people are going to treat you differently. Even if you’re not infectious I’m not sure people would appreciate that.”
Even if a person has recovered from COVID-19, experts advise they still be cautious when venturing outside of their home.
“一旦根据CDC准则清除了某人，他们应该采取与其他所有人相同的预防措施，因为我们只是不知道免疫力持续了多长时间。”Jaime Friedman博士在圣地亚哥的一名儿科医生告诉Healthline。雷竞技app官网“他们可能是孤立的，但应该继续与公众保持距离并戴上脸部覆盖。”
尽管有报道说有些人正在发展新冠肺炎twice, experts say it’s likely that if you are infected with the illness you are immune for a period of time.
But scientists don’t yet know how long COVID-19 antibodies will last in a person who has developed the disease.
沙夫纳说：“当您感染病毒时，您的身体的免疫系统会反应并对其做出反应。”“人体会产生称为抗体的蛋白质，这些蛋白质实际上是通过吞噬病毒而抗击病毒并不允许其附着在任何新细胞上的蛋白质。这将使您的病毒感染结束，因为病毒无法在体内进一步传播。这些非常具体的抗体，免疫系统保留了记忆和这些抗体在您的血液中持续存在的不同时间。”
他补充说：“不同的病毒抗体持续不同的时期。”“我们不知道Covid病毒抗体会持续多长时间。我们认为至少一年。这在科学主流中或多或少是待测试的。”
即使一个人从Covid-19中恢复过来，专家也建议不要在室内与他人一起访问。
“我会谨慎与家中的任何人一起访问。当人们长时间紧密接触时，尤其是当室内时，该病毒会更容易传播。”弗里德曼说。
“The safest contact with someone who you’re not quarantined at home with is contact that is outside, 6 feet apart, with everyone wearing a mask,” she added. “Significant exposure is considered less than 6 feet apart from someone for 15 minutes or more. Physical contact like hugging or kissing or sharing utensils is also considered significant exposure and should be avoided.”
Blumberg argues misinterpretation of social distancing guidelines has resulted in a spike in cases across the United States.
“At the end of May when some of the social distancing guidelines were relaxed, many people interpreted that as they no longer had to be careful and we saw an increase in visiting between households indoors, having parties, having gatherings, having social events and I think that’s directly lead to the increased number of cases that we’re seeing in many places. People are not following the science. They are following politics instead and that’s lead to a lot of confusion,” he said.
沙夫纳敦促人们倾听专家的意见，并遵循他们的身体距离和戴口罩的建议。
“Listen to the public health authorities, listen to the physicians. Listen to people who have genuine knowledge about this. Unfortunately, the wearing of masks and the response to the virus has become very politicized in this country,” he said.
“It’s fair to say that in most of the country, in most of the United States, we are struggling. We are not making good progress,” Schaffner added. “The virus is progressing, but the control efforts are not. It’s beyond a shame. It’s a scandal, it’s a disappointment, it’s profoundly sad. Beyond that, there are families who have lost family members. These were preventable deaths, preventable hospitalizations.”
Blumberg says all individuals, whether currently infected with COVID-19, recovered, or a friend or family member of someone in recovery, need to do their part to keep the community safe.
“This is the new normal and people just need to get used to it. It’s being a good community member. It’s caring about others within your family, within your community, within your state, and within your country to follow these recommendations and be hygienic. It’s the safe thing to do and it’s the right thing to do,” he said.
