Scientist warns over staff-to-staff transmissionTeachers have been warned that theyare spreading Covid-19 after a leading government scientist said they were far more likely to transmit the virus than children.New research from Public HealthEngland revealed that two thirds ofoutbreaks arose from staff-to-staff transmission, or staff-to-pupil. In June the number of schools open was between 20,500 and 23,400, withpupil numbers increasing from 475,000 to 1,646,000. In June and last month 200 children and staff were affected by the illness. Over the same period 25,470 cases were recorded across England as a whole. Thirty outbreaks, defined as two or more linked cases in one school, were recorded between the start of June and the end of last month. These represented 0.01 per cent of preschools and primary schools in England.The figures will encourage those whohave argued that school is a safe placefor children during the pandemic.Shamez Ladhani, a paediatric infectious diseases specialist at PHE, wholed the monitoring of England’s schools, said: “We need to educate the educators. There’s a clear need for aduty of care outside the school setting,so staff need to protect themselves andin turn other staff and pupils.“Staff are very good at social distancing and infection control in the classroom, but upon leaving the school environment these measures are more likely to be broken, potentially putting themselves and their colleagues at risk.”Last night Boris Johnson exhorted parents to send their children back to school next week, declaring that a return to the classroom was “vitally important” to their life chances.The prime minister paid tribute to staff who had spent time over the summer devising plans to ensure that their schools were “Covid-secure”. He has previously emphasised the moral duty to reopen schools safely.Ministers now understood more about the virus, Mr Johnson said, with evolving guidance from medical and scientific experts. “As the chief medical officer has said, the risk of contracting Covid-19 in school is very small and it is far more damaging for a child’s development and their health and well being to be away from school any longer.“This is why it’s vitally important that we get our children back into the classroom to learn and to be with theirfriends. Nothing will have a greater effect on the life chances of our children than returning to school.”In a joint statement, the UK’s chief medical officers said that the evidence “reinforces the need to maintain social distancing and good infection control inside and outside classroom settings, particularly between staff members and between older children and adults”. The study also found that outbreaks in schools were more likely in areas that had a high rate of cases in the community — raising the chances that shops or restaurants may need to close in such areas to allow schools to remain open.#thetimesUK
