All you need to know about long Covid 19 symptoms 10 points

India August 06(IM): One in eight adults who are infected with SARS CoV 2, develops long term Covid 19 symptoms like chest pain, back pain, nausea, painful muscles, difficulties with breathing, lump in the throat, general tiredness, heavy arms or legs, etc, according to a new study published in The Lancet journal. Notably, this is the first study which is able to identify which persistent symptoms are particularly related to SARS CoV 2 infection.

The research draws comparison between long term symptoms after long Covid 19 infection with symptoms in an uninfected person as well as measuring symptoms in individuals both pre and post Covid 19 virus. It laid emphasis on the symptoms most often associated with long Covid 19 and gives an estimate at how likely it occurs in the general population.

A total of 76,400 adults in the Netherlands were asked to fill out an online questionnaire on 23 common long Covid 19 symptoms. Each participant filled out the questionnaire 24 times between March 2020 August 2021. During this, more than 4,200 people reported catching Covid 19.

Here are 10 points you need to know about long Covid 19 symptoms based on the study published by The Lancet,

1 During the study, the researchers analyzed as many as 23 symptoms which includes headache, dizziness, chest pain, back pain, nausea, painful muscles, difficulties with breathing, feeling hot and cold alternately, tingling extremities, lump in the throat, general tiredness, heavy arms or legs, pain when breathing, runny nose, sore throat, dry cough, wet cough, fever, diarrhoea, stomach pain, ageusia or anosmia, sneezing, and itchy eyes.

2 Those infected with Covid 19, over 21 percent patients had at least new or severely increased symptoms three to five months after getting infected. However, only 9 percent of a control group which did not have Covid reported a similar increase.

3 The study says that Covid 19 cases can be asymptomatic and remain undetected. Therefore, the prevalence of the coronavirus infection in this study might have been underestimated.

4 Multiple studies have assessed the persistence of somatic symptoms after getting infected with Covid 19, with timeframes of follow up varying from 21 days to six months, while some studies included participants from post Covid 19 support groups or predominantly patients who were hospitalized, leading to biased results.

5 The researchers found that several symptoms were new or more severe, three to five months after getting infected with Covid 19, as compared to the symptoms before its diagnosis.

6 After the survey, the researched found that the prevalent symptom was fatigue 11 to 42 percent of patients , followed by dyspnoea 8 to 37 percent , painful muscles 7 to 24 percent , and ageusia or anosmia 3 to 24 percent . Thoracic pain was reported in 3 to 14 percent of patients at 90–180 days after coronavirus infection.

7 Although they found similar prevalence rates for some of these symptoms and showed that these rates were lower when patients symptom severity before Covid 19 was taken into account, read the study, adding that the most prevalent symptoms are not the most distinctive symptoms for post Covid condition.

8 A large study that included 1,06,578 patients with Covid and matched controls with influenza, which assessed the persistence of seven somatic symptoms at 90 to 180 days after diagnosis, found that somatic symptoms, such as headache, chest pain, and fatigue, were more frequently present in patients with Covid 19 than in the controls.

9 In this study, the researches analyzed that fatigue and dyspnoea are among the the core symptoms, but the most distinctive symptoms also included chest pain and ageusia or anosmia considered important for the case definition by 55 percent and 57 percent of the Delphi panel, respectively .

10 This study overcame various limitations of other researches on SARS CoV 2 by performing sensitivity analyses restricted to participants with a Covid 19 diagnosis based on a positive SARS CoV 2 test and by the studys prospective design.
