Boris Johnson eliminates covid measures and restrictions in Great Britain and scientists raise the alarm: waves of infections risk, any new variants would not be intercepted quickly. “As members of the UK scientific and medical community, we are writing this open letter to express our concern about the government’s plans to end testing, surveillance investigations and legal isolation requirements for Covid-19 cases. We ask that the scientific opinion on which these political decisions are based be clarified “, reads the open letter addressed by a group of doctors and experts from various British universities (and disciplines) to medical-scientific advisers Chris Whitty and Patrick Vallance, to ask for clarification. on the choices made in the country. “We do not believe there is a solid scientific basis. It is almost certain that the circulation of the virus will increase and there will be no visibility of the emerging variants of concern.” The signatories, who are professors from universities such as University College London and the University of Oxford, and white coats from Gb healthcare realities, cite some passages contained in documents of the Sage (Scientific Advisory Group for Emergencies). Such as: “The emergence of new variants and the resulting wave of infections can occur very quickly, potentially within a few weeks.” Or they also call into question documents warning about the increase in Covid transmission that could occur “if self-isolation and tests are removed”. “We believe – continue the authors of the open letter – that science strongly supports the use of vaccines combined with public health interventions to slow down transmission and regain the upper hand over viral evolution. Some form of surveillance must be continued. The lack of testing is not only harmful for controlling the spread of Sars-CoV-2 and for detecting new variants, but it also puts people who develop Long Covid at a great disadvantage in not being able to have a confirmation of their infection. an integral part of the diagnosis, support and care they need to receive. ” “Every Sars-CoV-2 strain to date has been replaced by a new variant that is more transmissible, more capable of immune evasion or both,” warn UK experts. “This pattern is likely to repeat itself and further reinfections will occur, with a continuing burden of disease” and pressure “on the health system.” Hence the appeal for transparency on the scientific opinion that was given in support of the imminent turning point in British Covid policies.
