What actions should schools take to reduce transmission of COVID-19?
Evidence suggests that children are at a lower risk of contracting COVID-19 than adults. However, children are still susceptible to infection and are potential transmitters of the virus , even when not showing symptoms. Preventing the spread of COVID-19 among children is important to protect both the health of the children and to slow transmission of COVID-19 in communities, particularly among vulnerable groups.
School closures were among the first actions by governments around the world to prevent the spread of COVID-19. Schools should follow national and local guidelines advising when it is safe to re-open. UNESCO, UNICEF, the World Food Program, and the World Bank have published a framework for reopening schools, which provides re-opening guidance and recommendations for national and local stakeholders. Currently, a number of countries have fully or partially re-opened schools or are in the process of doing so and have employed different strategies to control COVID-19 transmission. Ensuring the physical protection of students, teachers, and school staff – including access to a hygienic environment and access to handwashing facilities – is an essential precondition for re-opening.
There are three key goals that need to be achieved for schools to contribute to COVID-19 reduction:
- Reducing person-to-person transmission
- Reducing contact exposure
- Ensuring students and school staff with key COVID-19 symptoms (or those in close contact with symptomatic individuals) stay at home, and supporting national policies on testing, contact tracing and isolating.
We discuss strategies to achieve each of these goals below. Recommendations are based on guidance on the prevention and control of COVID-19 in schools published by UNICEF, WHO and IFRC and by the WHO. The Global Education Cluster’s practitioner’s guide to safely reopening schools provides more detailed guidelines and checklists for reopening,and addresses a range of school-specific issues, including education, nutrition, child protection, mental health, and adapting approaches to camp settings.
How can person-to-person transmission be reduced in schools?
Reducing person-to-person transmission requires:
A. Promoting physical distancing
B. Promoting good respiratory hygiene practices
C. Improving hand hygiene behaviours
A. Promoting physical distancing
Schools should adhere to national and local guidelines on physical distancing in schools. There are several broad strategies to promote physical distancing, including:
- Visual cues that support spacing of greater than 1 metre (3 feet) (or distance advised by national government, if different)
- Reducing density of the buildings and campus
- Eliminating gatherings
- Closing or restricting gathering spaces.
For example, where schools are open, the following measures may be considered as part of these strategies to create safer environments:
- Staggering the beginning and end of the school day so that all pupils do not need to be present at the same time
- Cancelling assemblies, sports games and other events that create crowded conditions
- Holding breaks in shifts to avoid overcrowding in corridors and playgrounds
- Moving lessons outside if feasible, or ventilating rooms as much as possible
- Demarcating playgrounds into zones to ensure pupils do not mix more than necessary
- Placing marks on the floor to cue children to stand the correct distance apart while waiting to enter a room, for example painting colourful circles 1 metre apart (or distance advised in national guidelines) in the corridor (see above image for example)
- Introducing one-way systems for moving through buildings
- Creating space for children’s desks to be at least one metre apart (or distance advised in national guidelines)
- Installing desk-top partition/divider screens
- Reducing pupil-to-teacher ratios by increasing the number of teachers, if possible, to allow for fewer students per classroom (if space is available)
- Advising against crowding during school pick-up
- Ensuring only 1 child per seat on school buses and that they are at least 1 metre apart (or distance advised in national guidelines), if possible. This may require increasing the number of school buses per school. Keep windows on the bus open, if possible
- Creating awareness to ensure the students do not gather and socialise when leaving the school and in their free time
Adhering to physical distancing is just as important for adults working in the school as it is for the students. Teachers should model and teach correct physical distancing behaviours.
B. Promoting good respiratory hygiene practices
Children should be encouraged to cover their mouth and nose with their bent elbow or tissue when coughing or sneezing and to dispose of used tissue immediately. These messages should be incorporated into the curriculum, alongside broader hygiene promotion – refer to the section below entitled ‘Sharing age-appropriate COVID-19 information with children’.
Use of face masks or face coverings should be in line with local and national guidelines. Where masks are advised, care should be taken to use them safely. For more information on types of masks and how to use them safely see our resource entitled ‘Summary report on masks and COVID-19’.
C. Improving hand hygiene behaviours
There are a range of ways to improve handwashing behaviours. Below we describe how you can create an enabling environment, how to cue handwashing behaviour, how to incorporate hygiene promotion into the curriculum and how to create a schedule for frequent handwashing.
Create an enabling environment: Schools must enable good hygiene practices. To do this, schools should have:
- Handwashing facilities with both soap and water available at all times (See JMP requirements for basic hand hygiene facilities in school settings).
- Handwashing facilities that are accessible to all users and that consider different needs based on the student’s age, gender and disability.
- Water available through on-site taps, boreholes or from a reservoir with containers that are cleaned and filled regularly.
- An adequate quantity of safe water to allow for personal hygiene practices including handwashing and menstrual hygiene management, as well as for environmental cleaning.
Handwashing stations with soap and water, or alcohol-based handrub dispensers (with between 60%-80% alcohol) should be available:
- Near every toilet or bathroom to enable handwashing after using the toilet.
- At the lunchroom entrance to enable handwashing before eating.
- At school entrances to encourage students to wash hands with soap on arrival at school and upon departure.
- At the entrance of every classroom (if possible).
- In dormitories (where applicable).
- In food preparation areas (where applicable).
Make changes to the environment to cue handwashing: Changes can be made to the physical environment to help remind students and cue handwashing behaviour. These changes can be termed ‘environmental nudges’. This guide from the WASH in Schools Network (WinS) presents a select number of nudge-based interventions. We summarise some of these interventions here:
1. Painting colourful footprints that lead children from the toilet to the handwashing facility and handprints on the facility as a reminder to use it. One study in a school in Bangladesh showed that this nudge increased children's handwashing behaviour by 64%. In a subsequent cluster-randomised controlled trial, this footpath nudge was compared to a high-intensity education-based intervention and was found to be equally effective at the 5- month follow-up.
2. Placing an image of eyes above handwashing facilities to give the sense that others are watching and expect to see handwashing. One study in a women’s public restroom found people were 10% more likely to wash hands in the presence of these eyes.
3. Using soaps with toys embedded inside to draw children’s attention and incentivise them to wash their hands with soap frequently in order to reach the reward. A controlled study in a displacement camp in Iraq found that putting toys in soap made children 4 times more likely to wash their hands with soap in the household.
4. Placing pictures of germs on surfaces that many people touch, such as toilet door handle, to induce a sense of disgust after touching these surfaces and subsequently cue handwashing.
5. Placing mirrors above handwashing stations to make handwashing more desirable and encourage longer handwashing.
6. Drawing attention to the soap dispenser or handwashing station with bright colours

Include hygiene promotion as part of the curriculum: Hygiene promotion should be part of the school curriculum. Content should be age-, gender-, ethnicity- and disability-responsive. For more information on how to include hygiene promotion for different age groups (pre school, primary school, and secondary school) refer to the section below entitled ‘Sharing age-appropriate COVID-19 information with children’.
Create a schedule for frequent hand hygiene, especially for young children: Frequent hand hygiene should be established by scheduling times for handwashing sessions supervised by teachers or other school staff. For example, students may be asked to wash their hands hourly.
How can we reduce surface related transmission of COVID-19 in schools?
Though the primary route of COVID-19 transmission is via direct contact with an infected patient, individuals can also be indirectly infected via contact with surfaces in the immediate environment or with objects used by an infected person.
Reducing contact transmission (such as on surfaces) requires:
A. Extensive cleaning and maintenance of facilities
B. Reducing high-touch surfaces
A. Extensive cleaning and maintenance of facilities
Surfaces and laundry (when applicable) in all environments where students, teachers and non-teaching staff spend time (classroom, dining areas, playrooms, staff rooms, dormitories, laboratories) should be cleaned and disinfected at least once a day. This is particularly important for water and sanitation facilities and other surfaces that are touched by many people (high-touch surfaces), such as tap handles, railings, lunch tables, sports equipment, door and window handles, toys, and teaching and learning aids.
The World Health Organisation recommends that surfaces are always cleaned with soap and water or a detergent to remove organic matter first, followed by disinfection. In school settings, sodium hypochlorite (bleach) may be used at a recommended concentration of 0.1%. Alternatively alcohol with 70%-90% concentration may be used for surface disinfection, an option which may be more suitable for cleaning small objects. Where disinfectants are being prepared and used, the minimum recommended personal protective equipment (PPE) is rubber gloves, impermeable aprons and closed shoes. For more detailed information on disinfection of surfaces and laundry see our resource entitled ‘Preventing COVID-19 Transmission via Surfaces’.
Trash should be removed daily and safely disposed, and airflow and ventilation should be maximised where climate allows, for example by opening windows or using air conditioning where available.
An operation and maintenance routine should be established to ensure cleanliness and functionality of facilities and provision of consumables. If soap is available and facilities are functional and clean, teachers’ messages around hygiene may be more credibly conveyed. Cleaning items such as commercial detergents, mops, buckets, and basic PPE (to the extent possible) should be provided for use by cleaning staff in schools. Schools should regularly assess their WASH environment and endeavour to make improvements in manageable steps. The complete UNICEF guidelines for water, sanitation and hygiene (WASH) in schools can be found here.
Various members of the school community – including management committees, teachers, janitors, cleaning staff, school health staff, and students – can help in efforts to improve a school’s WASH environment. Key roles should be identified and assigned. The WHO offers advice on assigning roles to members of the school community (Annex 1).
A school’s community does not stop at the school itself. Parents, technical experts and community leaders can help identify problems and develop solutions, as well as provide additional funding and support implementation. Tips for engaging the wider community can also be found in the WHO guide mentioned above. Leaders of the school management committee should take overall responsibility for ensuring members of the school community play their role accordingly. Available evidence supports this whole-community approach to improving and maintaining facilities: a study in Kenya showed that WASH conditions can be improved within a school’s existing administrative structure when given a budget for purchasing WASH-related items; other studies have found that upfront local involvement, community financial support, a local champion, a maintenance plan, school management committee involvement, and giving students responsibility for monitoring and cleaning school latrines are all key factors on the pathway to well-managed school WASH facilities.
B. Reducing high-touch surfaces
Where possible, school administration may consider removing or modifying high-touch surfaces, such as communal furniture, toys, and sports equipment. This may also include propping open doors to minimise contact with door handles. The remaining high-touch surfaces should be identified for priority disinfection and cleaned at least once daily.
How can schools ensure students and staff with COVID-19 symptoms stay at home, and follow national policies on testing, contact tracing and isolating?
To support national policies on testing, contact tracing and isolating, schools should be in communication with local health authorities. Where local policies stipulate, school administration should notify health officials of positive COVID-19 cases identified within the school community. Schools should keep parents and teachers informed about the measures the school is putting in place and ask for their cooperation – inclusive and early collaboration between the school and the community is needed to develop and implement necessary measures.
While schools may not have the capacity to conduct tests themselves, they should do the following:
- Encourage students, teachers, and other school staff with key symptoms like cough and fever to stay home and get tested if possible. Schools may decide to conduct temperature checks on those entering the school building. In the event that symptoms are identified during school hours, a procedure should be in place for separating sick students and staff from those who are well – without causing stigma – and for informing parents/caregivers and consulting with health care providers/health authorities wherever possible. Students/staff may need to be referred directly to a health facility, depending on the situation, or sent home.
- Encourage students, teachers and other school staff with a family member showing symptoms to stay home and get tested if possible. Reinforce that caregivers should alert the school and health care authorities if someone in their home has been diagnosed with COVID-19, and should keep their child at home for 14 days after the onset of symptoms in the patient. Flexible attendance and sick leave policies should be in place that encourage students and staff to stay home when sick or when caring for sick family members.
- Ensure that students, teachers, and other school staff who test positive for COVID-19 relay school contacts, and advise that these contacts should stay home or get tested (if possible).
- Monitor absence daily. If higher-than-usual absence amongst students and teachers is noticed, inform health authorities immediately.
Guidance should be clearly communicated to children and family members in the appropriate local language, including pictorially if literacy levels are low.
How can schools share age-appropriate information on COVID-19?
To achieve the goals described above, children and young people should understand basic, age-appropriate information about coronavirus disease (COVID-19), including its symptoms, complications, and how it is transmitted and prevented. Activities should be contextualised further based on the specific needs of children (language, ability, gender, etc). Information should be shared in a fun and interactive way and repeated periodically. Below are the guidelines from UNICEF, WHO and IFRC on the information and activities that can be shared with children in different age groups. For ready-to-use resources, the WASH in Schools Network has compiled a knowledge map with links to relevant materials (e.g. songs, videos, activities, and information sheets) about COVID-19 for learners, their families and the education system.
Preschool (approximately age 2-5)
Children in this age group are rapidly expanding their language, social-emotional and cognitive skills and learn best through play, exploration and hands-on learning. Use stimulating activities and materials to share COVID-19-related messages with preschool-age children:
- Focus on teaching young children good health behaviours, such as covering coughs and sneezes with the elbow and washing hands with soap frequently.
- Sing a song while washing hands to practice the recommended 20 second duration. Children can also practice washing their hands with hand sanitiser if this is something that is available in the local context.
- Develop a way to track handwashing and reward frequent and timely handwashing. For example, try creating a handwashing sticker chart or giving certificates to students who are practicing good handwashing. Teachers should ensure that rewards are suitable for the local context.
- Use puppets or dolls to teach good health behaviours, to demonstrate symptoms (sneezing, coughing, fever) and what to do if feeling sick, and how to comfort someone who is sick (cultivating empathy and safe caring behaviours). There are many videos available online demonstrating how to make puppets such as this one.
- Use story books such as this to teach children about the virus and why we need to practice good health behaviours.
- Have children sit further apart from one another, have them practice stretching their arms out or ‘flapping their wings’, they should keep enough space to not touch their friends.
Primary school (approximately age 5-12)
Play-based learning is important for children in primary school. Fun, interactive opportunities enhance children’s mastery of taught concepts and build motivation to learn. Use interactive activities and stimulating materials to share COVID-19-related messages with primary school children:
- Listen to children’s concerns and answer their questions in an age-appropriate manner; don’t overwhelm them with too much information. Encourage them to express and communicate their feelings.
- Emphasize that children can do a lot to keep themselves and others safe. For example, introduce the concept of physical distancing (standing further away from friends, avoiding large crowds, not touching people if you don’t need to, etc.). Focus on good health behaviours, such as covering coughs and sneezes with the elbow and washing hands with soap.
- Give children illustrated books such as this to share messages about COVID-19 and how to control it.
- Help children understand the basic concepts of disease prevention and control. For example, use exercises that demonstrate how germs can spread. For example, by putting coloured water in a spray bottle and spraying over a piece of white paper, observing how far the droplets travel.
- Sing a song while washing hands to practice the recommended 20-second duration.
- Demonstrate why it is important to wash hands for 20 seconds with soap and water using fun, interactive activities. For example, put a small amount of vaseline on students’ hands and then sprinkle some glitter on top representing the virus. Have them wash them with just water, notice how much glitter remains, then have them wash for 20 seconds with soap and water. See a demonstration of this activity here. This activity can also be done with water-based paint instead of glitter. To also demonstrate how easily the virus spreads, have children touch frequently-touched surfaces, such as door handles, to see how the glitter/paint remains. Alternatively, put some ground black pepper (virus particles) into a bowl of water and ask a child to dip their finger into the “virus water”. When the child takes their finger out of the water, it has specks of pepper attached to it, representing “the virus”. Ask the child to then put some soap on their finger before dipping it back into the bowl of pepper and observe how the pepper rapidly moves away from the soap-covered finger. See a demonstration of this activity here. This activity also works with glitter and a toothpick.

- Have students analyse texts to identify high risk behaviours and suggest modifying behaviours. For example, a teacher comes to school with a cold. He sneezes and covers it with his hand. He shakes hands with a colleague. He wipes his hands after with a handkerchief then goes to class to teach. What did the teacher do that was risky? What should he have done instead?
Secondary school (approximately ages 12-18)
Children in this age group learn best via interpersonal approaches involving activities like discussion, group work and interaction with other students. Teaching related to COVID-19 should build on their prior knowledge and experiences:
- Make sure to listen to students’ concerns and answer their questions.
- Emphasize that students can do a lot to keep themselves and others safe. For example, introduce the concept of physical distancing. Also focus on good health behaviours, such as covering coughs and sneezes with the elbow and washing hands with soap. Remind students that they can model healthy behaviours for their families for example practicing good health washing at home and reminding and encouraging their families to do the same.
- Encourage students to confront and prevent social stigma related to COVID-19 (i.e. labelling, stereotyping, discriminating against someone or a group of people because of a perceived link with the disease). For example, discuss the different reactions they may experience around discrimination. Encourage them to express and communicate their feelings but also explain that fear and stigma make a difficult situation worse. Teach them that using language that perpetuates existing stereotypes can drive people away from taking the actions they need to protect themselves.
- Build students’ agency and have them promote facts about public health. For example, have students make their own Public Service Announcements through school announcements and posters or encourage already existing student leadership bodies to spearhead sharing messages related to COVID-19 in their schools.
- Incorporate relevant health education into other subjects. For example science classes can cover the study of viruses, disease transmission and the importance of vaccinations. Social studies can focus on the history of pandemics and evolution of policies on public health and safety. This can also include the role of various stakeholders including local leaders and the students in the fight against the COVID-19 pandemic. Media literacy lessons can empower students to be critical thinkers and makers, effective communicators and active citizens. Literacy studies can encourage students to contribute to community actions, for example, writing letters to members of the community who might be vulnerable during this time and joining local organisations in carrying out COVID-19 awareness campaigns.
Are there COVID-19 specific considerations for school feeding programmes?
According to WHO, it is unlikely that the COVID-19 virus is transmitted via food. However, precautions should be taken during the preparation and serving of food to avoid transmission from person to person or via surfaces. The following measures should be taken during the preparation and serving of food in schools:
- All chefs, food handlers, cashiers and other food personnel should practice frequent handwashing with soap.
- Chefs and servers should wear a mask when cooking and when serving food to students during mealtime. See here for guidance on types of masks and how to use them safely. Where possible, chefs and servers should also wear gloves.
- Cookware, plates, cups and cutlery should be cleaned with soap and water regularly, particularly before use. Consider procuring additional plates, cups and cutlery to prevent sharing, or ask children and young people to bring their own from home. Regularly remind children not to share the same cup or utensils for eating or drinking.
- If possible, meal times should be staggered to allow for physical distancing and to allow time for cleaning and disinfecting between shifts. Space out tables and chairs in dining areas so that they are two meters apart.
- Schools should review their menu and serve only hot meals if possible. The survival of SARS-CoV-2 at different temperatures is not thoroughly researched, however, reheating food at a temperature of 149°F (65°C) for at least 3 minutes is recommended.
- Ensure materials are available (soap, water, cloths) for cleaning/disinfecting kitchen surfaces or at points of cooking and waste bins/bags
- Disinfect the surfaces of food stores twice a day
- Keep windows open to allow air-flow when possible.
See here for further general information about disinfecting food products.
