The virus responsible for covid-19 continues to be studied by scientists and now more is known about SARS-Cov-2 than at the beginning of the pandemic that has already caused millions of infected people worldwide. In a recent study, carried out by British researchers, it was possible to conclude the most common symptom of the disease.
Dry cough and fever started to be indicated as part of the covid-19 symptoms and signs that we should pay attention to. To these were added other symptoms such as fatigue, stomach pain, loss of smell and taste, as well as mental disorders.
Now, a A team of British researchers asserts that the most common symptom among patients infected with the new coronavirus, especially in the youngest, is anosmia, a term used for partial or total loss of smell, and ageusia, weakening of the sense of taste.
This conclusion was reached after analyzing data from the National Statistics Service (ONS, in the follow in English), in the United Kingdom.
Between 15 August and 26 October, the British statistical office found that the number of people who tested positive for covid-19 and reported loss of taste and smell increased significantly in all age groups. That is, it is a symptom that is becoming more and more frequent among those who contracted the disease.
In patients over the age of 35, between 20% and 40% had loss of smell or taste, compared with about 15% to 25%, in the same group, who reported fever and between 13% and 18% of those who indicated cough.
The prevalence of this symptom was more evident in younger people. In patients under 35 years old, up to 60% of those who tested positive for covid-19 had anosmia, compared to about 15 to 25% who reported fever and those who signed fever (less than 10%).
In children, cough is uncommon
“People who test positive for covid-19 are generally more likely to experience symptoms of loss of taste or smell, and fever“, reads in the ONS report, quoted by the Daily Mirror.
In the analysis, ONS researchers report that fever is the second most common symptom.
The results of this investigation also show that schoolchildren infected with the virus are less likely to have a cough. “The rate of positivity of school-age children who have a cough remains low (about 5%)”, says the analysis, referring to data between August and October. On the other hand, says the statistic, the same indicator for young people under 35 and for those aged 35 or over “has steadily increased to around 10 to 15 percent”.
It is also revealed that the data analyzed by King’s College showed that 52% of infected children did not register the classic symptoms of adults.
What does DGS say about the symptoms?
The Directorate-General for Health (DGS) in Portugal states that “the signs and symptoms of covid-19 vary in severity, from the absence of symptoms (being asymptomatic) to fever (temperature equal to or greater than 38.0ºC), cough, headache. throat, tiredness and muscle pain “. In the most severe cases, DGS indicates “severe pneumonia, severe acute respiratory syndrome, septicemia, septic shock and eventual death”.
The national health authority states that more recently “anosmia (loss of smell) and in some cases loss of taste has been seen, as a symptom of covid-19”. “There is evidence from South Korea, China and Italy that patients with covid-19 developed partial or total loss of smell, in some cases in the absence of other symptoms,” reads the DGS website.
Research, however, continues on the new coronavirus to better understand the effects of the disease on people, what are the consequences, but also the ways of transmission of the virus, in order to fight it effectively.
