The UK ordered school closures from the 23rd of March 2020, later than the rest of Europe. In England, the government announced a phased re-opening of schools from the 1 st of June 2020 beginning with certain year groups identified as key transition years -children aged 4-6 years entering primary school, 10-11 years preparing to transition to secondary schools and, from 15 th June 2020 some face-toface contact for children aged 14-15 and 16-17 years due to take qualifying exams next year. Teachers, school governors, the public and doctors have openly challenged the decision (1,2). The UK government has not yet provided enough detailed information to convince the public, teachers and health practitioners, that effective systems for protection, test, trace and isolate, are in place to prevent and manage outbreaks in schools (3) . Risks of infection to children, staff and families must be weighed against the harms to children's education and social development. The potential consequences, if the re-opening of schools is managed badly, is second and subsequent waves of COVID-19 infection leading to more deaths, further school closures and prolonged restrictions, thus losing any ground gained thus far. This article weighs the risks and benefits of reopening schools before September 2020. Person-to-person transmission is the main driver for the spread of COVID-19 (4) but there is scientific uncertainty and conflicting evidence around the extent to which children can transmit the virus to teachers, parents and other children from a few small studies. An Australian study showed that only two students were identified as secondary cases amongst 735 students and 128 members of staff identified as close contacts of 9 students and 9 members of COVID-19 positive staff from 15 schools (5). There was no evidence of difference in rate of infection by age in China (6) and England (7) implying that children were as likely to be infected as adults but less likely to be symptomatic or develop severe disease (6) . Over 94% of 2135 children with confirmed or suspected COVID-19 in a Chinese cohort were asymptomatic or had mild to moderate symptoms (8) with better prognosis than adults (9) . A small proportion (5·2%) of children experienced. severe symptoms (8) . A meta-analysis of nine contact tracing studies concluded that children are half as likely as adults to catch COVID-19. However, the included studies were all considered low to medium quality, included few children, high variation among studies and the adult category included older adults who are known to be at increased risk (10) . newly identified multisystem inflammatory syndrome in children must be taken seriously with responsible and transparent communication of risk and knowledge (12) . A recent study in the Bergamo province in Italy found a 30-fold increase in incidence of this inflammatory syndrome since the start of the epidemic (13) . The numbers were small with 19 cases identified in the five years prior to the epidemic and 10 in two months during the epidemic. True infection and transmission rate cannot be accurately identified without mass testing. Children have been tested less frequently as they exhibit milder or no clinical symptoms (14, 15) . A recent report (18 May 2020) from Italy shows that 2% of 255,549 identified cases were in children aged 0-18 years (16) . Real-time monitoring to identify the daily number of new cases in all age groups and rate of transmission is needed to inform decisions at the local level. In children aged 10 years or younger, estimates from mathematical modelling in the UK on the risk of exposure to a contagious classmate show that risk of infection and death are low and get lower over time. Risk to children decreases by 90% if schools reopen on 1 st September 2020 (risk of infection 0·15%) compared to reopening on 1 st June 2020 (risk of infection 1·46%) (17). However, there were no estimates of risk to teachers and families. School closures disadvantage children's educational and social development. Achievement gaps leave the poorest socioeconomic groups lagging behind their more affluent peers (18) . school narrows these gaps but the gap widens over the long summer holiday (19) . Evidence is limited regarding the impact of other types of school closures on learning loss. Progress has been made since 2011 in narrowing the attainment gap between children from lower socioeconomic backgrounds and their peers but a recent rapid evidence review suggests there is a danger that these school closures could reverse this progress, with the median estimate indicating the gap could widen by 36% (20) . In the UK, the period between Key stage 2 (aged 7-8 years) and Key stage 4 (aged 15-16 years) has been identified as a crucial time to ensure that higher-attaining students from lower socioeconomic backgrounds remain on the high achievement trajectory (21) . During the closure of schools, teacher support for learning has continued remotely, including, but not exclusively digitally. However, the quality of the learning experience will have varied. In a teacher survey on 22 nd March 2020, 6,360 teachers responded to indicate that for state primary schools; 51% would be teaching using an online digital platform, with 49% using take-home physical worksheets/books. At state secondary, this was 82% and 19% respectively (22) . Worryingly, children from lower socioeconomic backgrounds were less likely to have online classes from their schools than their peers from higher socioeconomic backgrounds (~32% compared to 43% for primary, ~40% compared to ~58% for secondary) (23) . This could be related to availability of technology at school and teacher confidence. Schools are in a difficult position balancing the needs of their students; the more extensive the homelearning resources provided for children, the more some may be left behind, and yet, not providing them, reveals the gaps between schools. Either way, children from lower socioeconomic backgrounds are disproportionately affected. Alongside differences in what schools provide, children's home circumstances and parents' levels of engagement with home learning also vary. Those with poor academic and digital literacy, where parents are not fluent in English, and those with full-time jobs may struggle to keep up. This, combined with a lack of access to computers, books, learning space or other enriching opportunities create a home learning environment that is less conducive to learning (24) (25) (26) (27) . The UK government announced, in April, a plan to provide laptop computers to year 10 students from disadvantaged backgrounds (28), which are expected to be with schools shortly (29, 30) . School closures can exacerbate food insecurity, particularly for children living in poverty. Four million children (30%) in the UK live in poverty (31) . Children eligible for free school meals continue to receive these if in school. Those not in school receive support in the form of meals, food parcels or vouchers but this is only applicable during the current coronavirus situation (32) . More than 3 million adults in Britain reported going hungry since the lockdown came into effect with food security worse in households with children compared to those without (33) . School closures during lockdown has meant home confinement with no face-to-face social interaction with other children and adolescents, outside of the immediate household and restricted time outside of home. Approximately 1 in 10 children in Great Britain are likely to need treatment due to distress or social impairment from an underlying mental health disorder (34) . A survey of 1,784 children in China after home confinement for a month found that 22·6% reported depressive symptoms (35) , higher than previously identified (17·2%) (36) . Some children may have benefitted from school closures with experiencing less stress/pressure (particularly if bullied at school), receiving more attention from parents and spending quality family time. However, children in households under stress and children with additional needs are likely to experience adverse effects. Up to 40% of children receive special educational needs and disability support at some point across the child life course (37) . Social isolation, increased stress on parents and caregivers, uncertain access to food and housing, loss of financial income/support and worries about making ends meet carrying higher risks for child abuse (38) . This, combined with a lack of outside contact with teachers, healthcare professionals and social workers, raises the risk of missing opportunities to identify early signs of the need for safeguarding (39) . Schools in the UK have remained open for 'vulnerable' children but only 723,000 of the 2.3 million children in England with a vulnerable family background are estimated to be receiving statutory support and known to services (40) . The proportion of children known to be vulnerable attending school during lockdown has remained low (5% in early April to 14% in May) (41) . Calls to domestic abuse (42) and child support (43) helplines have increased during the lockdown. The Scientific Advisory Group for Emergencies (SAGE) compared insights from indicative modelling of seven scenarios for relaxing school closures to two baseline scenarios -schools remain closed (reproduction number R t of 0) and schools are fully reopened (R t of 1). The chosen option was to reopen for transition years before summer holidays which increases the modelled R t to 0·21. This is less than the impact of all primary schools reopening but higher than the most effective strategy identified (alternating one or two weeks on and off with half the class in each staggered group). The potential effects of social distancing, hygiene, testing and other safety measures in school were not incorporated into the modelling but will play a role in informing infection rate in schools as well as wider contextual issues. Most countries have implemented a phased reopening approach (44) . Others such as Italy, Spain, Portugal, California and parts of the UK (Scotland and Northern Ireland) opted for schools to remain closed until the new academic year. New Zealand and Israel have prioritised children with the greatest need such as those from vulnerable homes, younger children requiring adult supervision and children with learning difficulties. However, the success of such targeted approach may not be demonstrable in the UK as only 14% of 'vulnerable' children were in schools in May (41) . Germany and China have reopened schools for older children first prioritising those most able to comply with social distancing measures. Denmark has reopened primary schools and for older children due to take exams focusing on the urgency of educational need. There is insufficient scientific evidence to guide the decision to reopen schools for all or certain age groups. However, key influencing factors in most countries that have chosen to reopen schools are low daily number of coronavirus cases and high testing rates. What is the quality of experience that children are returning to? Schools will need to implement measures to maximise the safety of their staff and the children attending and so it is important to consider the experience that children return to in school. Measures to reduce contact include staggering drop-off and pick-up times, social distancing of parents outside school gates and not allowing parents to enter schools. Playtime may be limited with no tactile engagement or carpet time. Children will be separated into bubbles of 6-15 with interaction limited to within the bubble but these decisions will be made by staff rather than children who may have formed close friendships and want to interact with their friends. Desks will need to be spaced further apart to enable social distancing where possible and children may have to spend most of the school day sat behind a desk (45) which will be new for children in the first year of primary school. Use of outdoor spaces is encouraged and other innovative strategies will need to be identified such as large spaces and phased re-entry to overcome space limitations as more year groups come back. Regular hand washing, or hand sanitisation where washing is not possible, and not allowing children to bring toys and books from school can limit contamination. The use of personal protective equipment (PPE) are limited to staff in instances where it was previously used (in children whose care needs already involves the use of PPE) and if a child becomes unwell with COVID-19 symptoms while in school and needs care before they can return home (45) . The UK government has made the use of face coverings mandatory on public transport from 15 th June 2020 (46) and in public spaces where social distancing measures are hard to follow (47) . Teachers and other school staff may choose to wear use face coverings as a safety measure. The use of face coverings as a safety measure limits the visual cues and engagement with the teachers that children may have experienced in the past making for a less pleasant experience. There is significant fear and anxiety among teachers and parents around the risk of reopening schools (48, 49) . The focus has been on the risk to children but schools could become a mode of intra-and intertransmission for adults. The limited evidence and uncertainty around transmission from children means that some, if not all, concerns could be valid and thus safety measures need to be taken to mitigate the risk with communication of measures to reassure parents and teachers. Teachers need to be consulted in the decision making and implementation of measures at school level so that they feel confident and safe coming back. Responses to a recent online survey of 257,392 parents in England, Wales and Northern Ireland show that parents are concerned about their child not seeing friends and socialising (48%), missing out on learning from teachers (38%) and their child's mental health (35%). However, 90% of parents do not want their children to return to school immediately after lockdown ends (50) reflecting concerns around risk of infection. In addition to concern for children, parents with underlying conditions may be worried about exposure due to having to drop-off and pick-up their children from school. Similarly, teachers or other members of staff with underlying conditions who have either not been in work or have been in work for limited hours during the lockdown may be concerned about the risk to their own health. Infection fears, frustration, inadequate information, financial loss and stigma are psychological stressors of quarantine, the effects of which can be long-lasting (51) . Staff at schools should be supported and not pressured to be in work if their concerns cannot be alleviated through the implementation of safety measures. The approach to reopening schools will vary by school with consideration of the local context, for example, schools with higher representation of black and minority ethnic groups (BAME) are based in more deprived areas where risks are likely to be greater. A system to monitor reasons for absences should be in place to ensure appropriate steps for quarantine of cases and contacts are taken. What resources and long-term structures are needed to prevent and safely manage outbreaks? The daily number of coronavirus cases in the UK (~2000) is significantly higher than in other countries that have chosen to reopen schools (<500-1000) (52) . Community transmission varies between areas so a local approach to school reopening balances demands of safety and educational need, but needs J o u r n a l P r e -p r o o f community testing to know where rates are low. Increased testing and effective contact tracing and isolation for infected individuals has been identified as the most effective measure to prevent a second wave on school reopening. In this modelling, prevention of a further infection wave would require testing at least 51% of symptomatic people, with tracing 40% of contacts, and isolation of symptomatic and positive cases (53) . Consultation with teachers, school leaders, unions, parents and members from the local Councils and the community ensuring ethnic diversity in representation alongside a monitoring system is needed to identify the way to make this work. Surveillance by school staff is needed to detect symptomatic cases and to promptly isolate suspected cases, while testing is arranged. Schools are organised into small bubble groups and if one tests positive all staff and children in the bubble need to self-isolate for 14 days. Regular testing of teaching staff, children and their households offers a way to detect asymptomatic and pre-symptomatic cases but capacity is lacking (6, 54) . Using simple methods of sample collection such as saliva samples is likely to facilitate this process and enhance its acceptability (55) . Responding ad hoc to symptomatic cases will not be efficient or effective. Staff and children living in a household where others have symptoms of COVID-19 infection should self-isolate. Local Councils are responsible for co-ordinating the response to coronavirus arrangements by working with education settings to support schools and ensure there is sufficient capacity for the groups eligible to attend school or identify alternative options for provision (56) . The government needs to invest in coordination by local Councils with budgets that consider 'area deprivation' so that more funds are directed to more deprived areas of the country to enable them to support the safe reopening of schools. Long-term investment in schools to enable implementation of measures to maintain social distancing and changes to allow reorganisation of space and temporary use of alternative spaces also needs to be considered. Getting all children back to school is urgent to avoid further disadvantaging their education and social development but the competing demands of safety and education must be balanced. The balance is between reopening schools for a brief period for some year groups before the summer holidays against using the time to ensure safety measures are firmly in place. By September 2020, schools must be part of an effective and timely system of test, trace, isolate and support with complete transparency of the risks or trade-offs in the face of scientific uncertainty. This generation of school children will remember being locked down for years to come. When we fully reopen Pandora's Box, we must maximise the benefits for them as efforts to mitigate harms are likely to continue long into the future. Independent SAGE.
