That the Covid-19 virus has changed in its shape and spreading power is now well known. The variants, from English to Indian, are today one of the most important aspects to keep an eye on and to defend against with vaccinations and prudent behavior. However, it was not only the spread of the virus that changed, but also the ways in which the infection manifests itself. Fever, loss of taste, loss of smell, fatigue, may no longer be the same alarm bells of the past, capable of alerting the paucisymptomatic or asymptomatic of a possible infection in progress. This is a topic that scientists have been monitoring for several weeks, especially with regard to the correlation between changes in symptoms and the appearance of variants. These are not more serious symptoms but different percentages of occurrence, fundamental to be calculated for the early detection of the virus.
The theme should not be underestimated especially at this time: between reopening and progressive passages in the white area, the risk is to keep a less eye on one’s health status, underestimating the signs, perhaps new, of a possible Coronavirus infection. The data of the infections speak for themselves: Covid-19 still circulates in our country trying to replicate itself from organism to organism. Although with more difficulties, thanks to the high temperatures and the part of the population immunized by vaccines, its goal remains to replicate itself as much as possible and resist the measures that counter it, changing and adapting to the new organism it chooses to inhabit.
Smell and taste are no longer the main alarm bells
It was from the beginning one of the very first and in many cases also the only clinical manifestation of Sars-CoV-2 infection in patients with little or no symptoms. In the absence of immediate fever, the sudden loss of taste and smell was the wake-up call for many people, and they ran to run the test swab for the presence of Sars-CoV-2. According to a recent English study published in the British Medical Journal the 40% gods 19 thousand subjects studied no longer presents the symptom of loss of taste or smell, together with fever, another of the most frequent signs of all. To confirm is the English study on the characteristics of people who tested positive for Covid-19 in the period from December 2020 to April 2021. The new pandemic wave would in fact present itself with fever that is not always high, less sore throat or problems for the five senses “but with more nausea, cough, headache and persistent fatigue, which in many cases persists for a few weeks even after the negativity of Covid has been ascertained ».
Stomach pain, vomiting and diarrhea are the signs that should not be underestimated
He had explained it to Open a few weeks ago Antonietta Lamazza, gastroenterologist doctor and professor at the Sapienza University: «The literature reports from a 7% up to a 50% of gastrointestinal disorders linked to Covid-19. A figure that also varies from country to country: in China the percentage is lower, in the US there is a higher incidence. As far as our country is concerned, they are around 15% with tips of the 30%“. Doctors continue to collect more Covid-19 patients who complain of gastrointestinal problems among the first symptoms. «One of the most frequent requests we receive is that of endoscopic examinations for very strong diarrhea, on which normal therapies have no effect. A symptom that often remains even after the negativization by the virus, up to 9-10 monthsContinues the doctor. General doctors also confirm. The direct verification of the patients described by the secretary of the Italian Federation of General Practitioners, Pier Luigi Bartoletti, appears quite clear: “The loss of smell and taste is now replaced by abdominal pain, vomiting or diarrhea”.
To further confirm there would also be the all-Italian study of the Crema hospital conducted on a limited number of patients for now and came to the conclusion “that the 10% of the infected hospitalized suffer abdominal pain, diarrhea, nausea and vomiting already from the first days of the disease and even before the classic respiratory symptoms appeared ». Doctors conclude that “gastrointestinal symptoms may herald Covid-19 having occurred on average from 4 to 9 days before admission, with a very wide range up to 20 days before admission “and that” the data confirm the importance of including gastrointestinal symptoms in the spectrum of the characteristics of Covid-19, to allow early diagnosis and appropriate treatments even in patients without respiratory symptoms “.
Are there any “English” variant symptoms?
I study REACT – Real-time Assessment of Community Transmission, conducted by Imperial College London, monitored and analyzed from June 2020 to January 2021 how the virus has affected people. The results collected made it possible to highlight how the symptoms of the infection changed in this time frame: in January 2021 the affected subjects reported less loss of taste and smell than in November / December 2020, and more cough problems. In addition to the fever, then, were also declared: chills, loss of appetite more in people among the 18 and 54 years old and in over 55, headache, especially in young people between 5 and 17 years and muscle aches, mainly in the age group 18 and 54 years old. Regarding other possible changes in the manifestations of the virus spread by the variant currently most widespread in the world, there seem to be no other particular reports to be made, as confirmed by the study published by the famous scientific journal The Lancet. “The lack of strong changes in symptoms identified in this study indicates that the existing testing and surveillance infrastructure does not need to change specifically for variant B.1.1.7,” the paper reads.
