From today all students in Years 11, 12 and 13 will be required to wear nose and mouth coverings at Jersey schools.
The masks should be worn in areas outside of the classroom where social distancing is difficult. Students in these year groups will also be tested regularly.
Teachers, staff and adult visitors to schools are also being advised to wear a face shield or mouth and nose covering when teaching indoors or moving around indoor communal areas.
Some children and adults will be exempt from the advice. This includes:
People who cannot put on, wear, or remove a mouth and nose covering because of a physical or mental illness, impairment or disability.
People who would experience severe distress putting on, wearing, or removing a mouth and nose covering.
People who are speaking to, or assisting, someone who relies on lip-reading, clear sound, or clear facial expressions to communicate.
Exemption cards will be available from the school for both members of staff and pupils.
Mouth and nose coverings can help prevent the transmission of respiratory droplets, and help prevent the transmission of COVID- 19. While there is growing evidence that younger children are not super-spreaders, the risk of transmission is greater in older children and young adults which explains why we have limited face coverings to this group.
It comes as the government has announced further measures as cases in the island continue to rise.
Earlier this month Jersey's Chief Minister said that young people were becoming "far too relaxed" in their attitude towards public health guidance, and that this was having a "significant impact" on the spread of Covid-19 in Jersey.
Senator John Le Fondré says cases have been tracked back to Halloween parties and other gatherings in confined spaces, where physical distancing was not maintained, and sharing of drinks and vapes had contributed to the spread of the virus.
He has urged parents to encourage their children to follow the rules, and warn them that tighter restrictions could be brought in if they do not change their behaviour.
