Contingents normally take their own basic First Aid kits to any camp, and have at least several First Response trained adults (along with at least several hundred other trained adults on site) and there is then permanent 24 hour First Aid provision on site.
It is important that when asked you give your contingent leader full details of any known allergies, medical or behavioural conditions so that your Cub can be given the right support / treatment should the need arise.
Your contingent will give details nearer the time of how they will handle medicines, inhalers etc.
