An allergy develops when the immune system recognises and responds to something in the environment that is normally harmless: e.g. food proteins, pollens or dust mite. An allergic reaction occurs when a child is exposed to that substance and the body's immune system reacts to that substance. Symptoms may be localised or generalised, and range from mild to severe.
The most common causes of allergic reactions in young children are:
Other causes are bee or other insect stings, medication and latex (rubber).
This term is used to describe a severe allergic reaction that involves the respiratory and/or cardiovascular systems. Anaphylaxis is the most severe form of an allergic reaction and is life threatening.
A reaction can develop within minutes of exposure to the allergen, but with planning and training, a reaction can be treated effectively by using an adrenaline injection (EpiPen®/EpiPen® Jr). An important aspect of anaphylaxis management is prevention and avoidance of the cause.
The most common causes of anaphylaxis are peanut, tree nuts, egg and cow's milk. Other causes include antibiotics, bee and insect stings.
A mild to moderate reaction will include one or more of these symptoms, and it is possible that a number of them will occur simultaneously:
Anaphylaxis is the term used to describe a severe systemic allergic reaction that involves the respiratory and/or cardiovascular system. Presentation of any of the symptoms below, in addition to one or more of symptoms of a mild-moderate allergic reaction, indicates anaphylaxis:
The first line treatment for anaphylaxis is adrenaline, which may be given as an EpiPen® Jr for children weighing less than 20 kgs or and EpiPen® injection for children weighing 20 kgs or more. An EpiPen®/EpiPen® Jr is a single dose of auto-injector of adrenaline, which is prescribed by a doctor.
Banning of products that contain the allergen is NOT recommended.
Banning will not succeed in creating an "allergy free zone". It is difficult to achieve a 100% ban, for a variety of reasons. For example, product labels can be confusing, parents of non-allergic children may not comply with the ban, and lastly, staff and students become complacent.
The child at risk of food allergies should not share food. These children must only have food provided from home or given with the parent's permission.
Any staff, including relief staff, who are responsible for cooking or delivering food to children should know about the child's allergies. They should be aware of alternative words used to describe the particular allergy food. For example, cow's milk may be called casein, and egg may be called ovalbumin. They should also be aware of potential contamination of other foods when preparing, handling or displaying food.
Food containers or packages that contain the allergy food should not be used. Parents of children with anaphylaxis can help by checking art/craft products for hidden ingredients, as they are often more aware of terms used.
Separate tables should be used for art/craft and food. Where this is not possible, tables must be cleaned thoroughly between uses.
The EpiPen®/EpiPen® Jr must be taken on all excursions and a staff member trained to use the EpiPen®/EpiPen® Jr must always be present. The EpiPen®/EpiPen® Jr must be readily available.
