What is Post-COVID syndrome / Long COVID?

Long Covid symptoms

Some people who contract COVID-19, even if they have experienced mild symptoms, can not recover fully from the effects of the virus. They may continue to experience symptoms, months after initially falling ill. Patients may continue to have wide-ranging and fluctuating problems including breathlessness, chronic fatigue, “brain fog”, weakness and insomnia and dizziness.

Post-COVID or long COVID syndrome is defined as a number of symptoms that develop during or following an infection consistent with COVID-19. They would continue for more than 12 weeks and are not explained by an alternative diagnosis.


People experience several clusters of symptoms, often overlapping. These may fluctuate, and can affect any system within the body. Many people with post-COVID syndrome experience generalised pain, fatigue, persisting high temperature and psychiatric problems. Long term effects of the illness can be debilitating, even for young and fit people, who had mild covid symptoms at the time of infection, and who did not initially go to hospital.


Symptoms of Long Covid

Common symptoms may include:

● Debilitating fatigue

● Intermittent fevers

● Breathlessness, dry cough, ‘lung burn’

● Palpitations or cardiac arrhythmias/heart rhythm disturbances, chest pain

● Loss of smell or taste and sometimes a distorted sense of smell (parosmia)

● Abdominal pain and diarrhoea

● Skin rashes and ‘covid toes’ - where toes look bruised


These symptoms may fluctuate or be consistent. Many Long Covid sufferers also experience post-viral fatigue syndrome (PVFS), or Myalgic Encephalomyelitis, otherwise known as Chronic Fatigue Syndrome (ME/CFS) symptoms.

These include:

● Activity-induced muscle fatigue, weakness and muscle twitching

● Muscle, nerve and joint pains but without joint redness or swelling

● Headaches

● ‘Brain fog’ or cognitive dysfunction

● Sensory disturbances such as intolerance to light, sounds, heat or cold

● Dysautonomia – dysfunction of the autonomic nervous system. These can include

increased pulse rate, orthostatic intolerance - dizziness, fatigue and other symptoms on standing , postural hypotension and postural orthostatic tachycardia syndrome/PoTS

● Unrefreshing sleep, which may include excessive sleep

● Problems with temperature regulation - feeling too hot or cold and inability to maintain a stable temperature.

● Post-exertional malaise (PEM), exhaustion after performing basic tasks, such as brushing teeth, or walking up stairs which is not adequately relieved by rest or sleep.


Testing for Long Covid

If you experience prolonged symptoms after contracting Covid, it is important to visit your GP. They will ask about your symptoms and the impact they have on your life. They may suggest tests to find out more about your symptoms and rule out other things that

could be causing them. These may include blood tests, checking your blood pressure and heart rate or a chest X-ray. Unfortunately, there are no definitive tests for long covid at the moment.


It is not known how many people experience Long COVID symptoms, as the illness is so new and research is ongoing. It is estimated that over 70,000 people in the UK are experiencing Long COVID, although this is likely to be higher and will grow as coronavirus infection rates rise.


Treatment for Long Covid

Your GP may be given advice about how to manage and monitor your symptoms at home. If you are severely impacted by long covid symptoms, you may be referred to a specialist rehabilitation service or a service that specialises in the specific symptoms you have. These services can help manage your symptoms and live well within the limits of your illness but however there is no definitive treatment for recovery, and researchers continue to try to find a cure.


The symptoms of Long Covid are very similar to Myalgic Encephalomyelitis (ME/CFS). The advice is also similar:

● Pace yourself - plan what you’re going to do throughout the day and don’t over-exert yourself.

● Try to break tasks which feel difficult down into smaller chunks, and alternate easier and harder activities.

● Consider the best time of the day to do certain activities based on your energy levels.

● Frequent short rests are better than a few longer ones, so rest before you become exhausted.

● As with ME, patients should not overexert themselves as this can cause symptoms to

get worse and with temporary or permanent effect. They should physically and mentally

rest where needed.


The ME Association has supported people with post viral fatigue and ME/ CFS for a number of years. They have brought out a leaflet about Long Covid which provides information and further advice.

甚麼是後冠狀病毒綜合症/長遠冠狀病毒影響 (Long COVID)?

一些曾感染了冠狀病毒的人士並不能完全康復,即管他們只有輕微的徵狀。他們可在感染

病毒數多月後持續呈現不同的冠狀病毒徵狀,如氣喘、極度疲倦、思想模糊、體弱、失眠

及暈眩。


後冠狀病毒綜合症或長冠狀病毒是形容在感染冠狀病毒期間或之後出現的徵狀。這些徵狀

可持續多於12個星期,及不能斷診為其他病症。 有此病症的人會經歷不同組合,而又會

重叠的徵狀。這些徵狀會出現波動及可能影響身體中不同的系統。許多患有後冠狀病毒綜

合症的人會經歷頭痛、疲累、持續高溫和精神問題。這病症的長期影響是會使人衰弱,即

使是年輕和健康的人及他們感染時只出現輕微徵狀及並不曾入住醫院。


長冠狀病毒的徵狀

一般徵狀包括:

  • 衰弱疲累

  • 間歇性發燒

  • 氣喘、乾咳、肺部感到灼痛

  • 心悸或心律失常、胸部疼痛

  • 失去味覺或出現異常嗅覺 (parosmia)

  • 腹部疼痛和腹瀉

  • 皮疹和“冠狀病毒腳趾” ─ 腳趾看起來有瘀傷


這些徵狀可間歇或持續出現。很多長冠狀病毒患者亦會出現「病毒後疲勞綜合症」(post-

viral fatigue syndrome) 或肌痛性腦脊髓炎/雅皮士流感 (Myalgic Encephalomyelitis),亦

稱為「慢性疲勞綜合症」(Chronic Fatigue Syndrome ),徵狀包括:

  • 活動引致的肌肉疲勞、虛弱及肌肉抽搐

  • 肌肉、神經及關節疼痛但關節沒有出現紅腫

  • 頭痛

  • 思想模糊或認知功能障礙

  • 感官障礙

  • 自主神經紊亂 – 這是自主神經系統的障礙,這些可包括脈搏跳率上升、「直立性低血壓」 (Orthostatic intolerance)、「體立性低血壓」 (postural hypotension) 及「姿勢性直立心搏過速症候群」(Postural orthostatic tachycardia syndrome)。 

  • 睡眠後仍感到不飽滿,也可包括過度睡眠。

  • 調節體溫困難

  • 勞動後不適 (Post-exertional malaise (PEM) or symptom exacerbation

長冠狀病毒檢測

若你在感染冠狀病毒後呈現延長徵狀,便應約見家庭醫生。他們會去瞭解你的徵狀及這些

徵狀對你生活的影響。他們或會建議你進行一些檢測以更能精確地診斷你的病症及撇除其


他可呈現類似徵狀的病症。這些檢測可以是檢血、量血壓及心跳或為胸部照X光鏡片。遺

憾的是,現時還未有針對的長冠狀病毒檢測。


由於這是新的病毒及研究還在進行中,所以現時未知有多少人經歷長冠狀病毒徵狀。據估

計英國大概有70,000人仕呈現長冠狀病毒徵狀,但這數字可能會更高及會因病毒感染率

的上升而增長。


長冠狀病毒的治療

你的家庭醫生或可提供一些如何在家中管理及監測你的徵狀。若你受到嚴重的影響,你可

以被轉介到一個專科康復服務或一個專治你所呈現的徵狀的專家。


這些服務能協助你管理這些徵狀及在這個病症的限制下生活得好些。現時並沒有能有効治

療這個病症的方法,但研究人員會繼續尋找。


長冠狀病毒的徵狀與或「肌痛性腦脊髓炎」/「雅皮士流感 」(Myalgic Encephalomyelitis),亦稱為「慢性疲勞綜合症」(Chronic Fatigue Syndrome ) 的徵狀極相近,因此,管理建議亦相近:

  • 調整你的生活步伐 ─ 計劃你整日的行程,不要令自己過份勞累。

  • 嘗試將你認為困難的工作分成較小部份,及將容易和困難的活動交替進行。

  • 根據你一天的能量來計劃什麼時候應做什麼的活動。

  • 頻繁的短暫休息較幾次長時間休息為好,所以,在你精疲力竭前休息。

  • 切記不要令自己過份勞累,這只會令症徵更嚴重及引至短暫或永久的後果。在有需

要時,要令身及心休息。
