感染流感后也会出现类似长新冠的症状
本周在哥本哈根召开的欧洲临床微生物与传染病学大会（European Congress of Clinical Microbiology & Infectious Diseases）上发布的最新研究结果。
本周发布的最新研究报告称，感染流感还是新冠或许并不重要，因为你可能患上的病毒后疾病症状看起来高度类似。
长新冠是感染新冠之后发生的一种病毒后疾病。新冠感染急性后遗症（简称PASC）通常被定义为感染后出现的新症状，持续至少四周，往往可能长达数月甚至几年。
感染其他病毒后，例如流感、疱疹、莱姆病甚至埃博拉和SARS等，也可能出现类似的病毒后疾病。病毒后疾病通常表现出与慢性疲劳综合征类似的症状，如疲劳、脑雾和劳累后不适等，这些症状会在精神或体力活动后恶化。
对感染者患病毒后疾病的比例以及症状的严重性研究发现，新冠患者的病毒后疾病相比流感患者并不严重，至少在奥密克戎时代是这样。这是本周在哥本哈根召开的欧洲临床微生物与传染病学大会（European Congress of Clinical Microbiology & Infectious Diseases）上发布的最新研究结果。
该项研究调查了澳大利亚昆士兰的居民。在2022年初全球爆发奥密克戎之前，当地超过90%的人口已经接种了疫苗。
研究人员用12周时间，跟踪了近2,200名实验室确诊感染新冠的成年人，以及近1,000名实验室确诊感染流感的成年人。有五分之一（21%）奥密克戎患者在12周内有持续症状，有4%报告的症状对其日常生活产生了中等或严重影响。
流感患者的比例几乎相同，有23%在12周内有持续症状，有4%报告的症状对其日常生活产生了中等或严重影响。
但昆士兰卫生部的研究人员表示，长新冠之所以对医疗体系产生巨大影响，原因是新冠感染者的绝对数量。
据世界卫生组织（World Health Organization）统计，过去三年，澳大利亚有超过1,100万例实验室确诊的新冠感染者，而且这个数据可能严重低估了实际人数。
相比之下，去年澳大利亚实验室确诊的流感患者只有略超过225,000人。
昆士兰首席健康官约翰·杰拉德博士在新闻稿中表示：“我们的人口疫苗接种率较高，因此长新冠对公共健康的影响，似乎并不是源于SARS-CoV-2的任何特性。相反，这源于短期内感染者的绝对人数。”
长新冠风险因素
有趣的是，研究指出，下列群体在感染奥密克戎或新冠之后，日常生活受到中等或严重功能限制的可能性较低：
老年人
土著人
澳大利亚约5%至10%的新冠感染者报告的症状持续超过三个月。澳大利亚联邦卫生部门表示，下列群体面临的风险更高：
女性
中年人
严重新冠患者
《健康事务》（Health Affairs）期刊3月份的一篇文章表示，总体而言，有下列健康问题的患者出现长新冠症状的风险更高：
高血压
慢性肺病
肥胖症
糖尿病
抑郁症
如何预防长新冠
预防长新冠最好的方法依旧是防止感染新冠，可遵守美国疾病预防控制中心（U.S. Centers for Disease Control and Prevention）的下列建议：
戴口罩
保持社交距离
经常仔细洗手
远离已知感染者
接种新冠疫苗被普遍认为可以降低长新冠风险。《哈佛健康》（Harvard Health）杂志称，接种一剂疫苗可将风险降低35%。
德克萨斯大学健康科学中心休斯敦大学（UTHealth Houston）和纪念赫尔曼德州医疗中心（Memorial Hermann）首席传染病和流行病学专家、德克萨斯大学健康科学中心休斯敦大学新冠卓越中心（COVID-19 Center of Excellence）传染病主任刘易斯·奥斯特罗斯基博士对《财富》杂志表示，在降低长新冠风险方面，“接种疫苗的效果显著”。
如何预防感染流感后的病毒后疾病
如果你希望在感染流感后避免病毒后疾病，上述建议同样适用。奥斯特罗斯基表示：“前提是，避免长新冠或病毒后疾病的最佳途径是不感染病毒。”
他表示：“新冠真正让我们认识到戴口罩和洗手的重要性。在冬季并非一定会得病。你完全可以避免。”
接种新冠疫苗，不能帮助你预防流感。但他表示，流感疫苗可降低感染流感后出现病毒后并发症的风险。（财富中文网）

When looking at the percentage of those infected who develop post-viral illness, as well as the severity of symptoms, post-viral illness from COVID generally isn’t more of a problem than that from flu—in the Omicron era, at least. That’s according to new findings presented this week at the European Congress of Clinical Microbiology & Infectious Diseases in Copenhagen.
Flu or COVID, it may not matter—the post-viral illness you potentially wind up with could look pretty similar, according to new research released this week.
Long COVID is a post-viral illness that occurs after infection with COVID. Also known as PASC, or post-acute sequelae of COVID, it’s typically defined as new symptoms that develop after infection and persist for at least four weeks—often for months, and sometimes for years.
Similar post-viral illnesses can occur with other viruses, too, like the flu, herpes, Lyme disease—and even Ebola and SARS. Post-viral illnesses often have a chronic fatigue syndrome-like presentation, with symptoms like fatigue, brain fog, and post-exertional malaise, in which symptoms get worse after mental or physical activity.
When looking at the percentage of those infected who develop post-viral illness, as well as the severity of symptoms, post-viral illness from COVID generally isn’t more of a problem than that from flu—in the Omicron era, at least. That’s according to new findings presented this week at the European Congress of Clinical Microbiology & Infectious Diseases in Copenhagen.
The research took place among residents of Queensland, Australia, where more than 90% of the population had been vaccinated before Omicron burst onto the global scene in early 2022.
For 12 weeks, researchers followed nearly 2,200 adults who had been diagnosed with lab-confirmed COVID, and nearly 1,000 adults who had been diagnosed with lab-confirmed flu. Of those who experienced Omicron, a fifth (21%) had ongoing symptoms at 12 weeks, and 4% reported symptoms that had a moderate or severe impact on daily living.
When it came to those who had experienced the flu, the numbers were almost identical, with 23% reporting ongoing symptoms at 12 weeks, and 4% reporting moderate or severe impacts on daily living.
But there’s a reason why long COVID is having an outsized impact on the health care system, researchers from Queensland Health said in a news release: the sheer volume of COVID infections.
There have been more than 11 million lab-confirmed COVID infections over Australia in the last three years, according to the World Health Organization—a number that is likely a massive undercount.
By comparison, Australia only recorded only a little more than 225,000 lab-confirmed cases of flu last year.
“In our highly vaccinated population, the public health impact of long COVID does not appear to result from any unique property of SARS-CoV-2,” Dr. John Gerrard, Queensland’s chief health officer, said in the release. “Rather, the impact results from the sheer number of people infected over a short period of time.”
Long COVID risk factors
Interestingly, the study noted that those who were members of the following groups were less likely to report moderate or severe functional limitations on their daily lives after Omicron or flu:
older individuals
members of indigenous populations
Around 5% to 10% of Australians who’ve had COVID report symptoms lasting for longer than three months. People who are part of the following groups seem to be at greater risk, according to the country’s federal health agency:
female
middle age
those who’ve had severe COVID
In general, people with the following health conditions are at a greater risk of developing long COVID, according to a March journal article in Health Affairs:
hypertension
chronic lung disease
obesity
diabetes
depression
How to prevent long COVID
The best way to prevent long COVID continues to be to prevent COVID infection, by doing the following, according to the U.S. Centers for Disease Control and Prevention:
masking
social distancing
frequent, quality hand-washing
staying away from those with known illness
It’s widely thought that COVID vaccination could reduce the risk of developing long COVID. Just a single shot could reduce your risk by 35%, according to Harvard Health.
When it comes to reducing long COVID risk, “vaccinating goes a very long way,” Dr. Luis Ostrosky—chief of infectious diseases and epidemiology at UTHealth Houston and Memorial Hermann in Texas, and the infectious diseases director for UTHealth Houston’s COVID-19 Center of Excellence—tells Fortune.
How to prevent post-viral illness from the flu
If you’re looking to prevent potential post-viral illness from the flu, the same recommendations apply, Ostrosky says: “The premise is that the best way not to get long COVID or post-flu issues is to not experience the diseases themselves.”
“COVID was a real eye-opener for all of us as to the power of masking and hand hygiene,” he adds. “It’s no longer automatic to get sick in the winter. You can very likely avoid it.”
A COVID vaccine won’t help you when it comes to the flu. But a flu vaccine could reduce your risk of developing post-viral complications from the flu, he advises.
