Scabies is a benign but very contagious disease and is very troublesome because of the intense itching that it causes. It can also result in social stigma. It is caused by a small acarid, an itch mite, with the female burrowing down into the epidermis to lay eggs. It has been progressing for several years in France and Europe yet very little epidemiological information is available. It is not a reportable disease and is not tracked by conventional epidemiology surveillance networks. The Scabies IAS® published by OpenHealth responded to this lack of information. It enables spatial-temporal progression to be tracked in France.

The information used are sales data for medicines sent by member pharmacies of the Celtipharm network. Pharmacies automatically send their information every day. It is anonymous information based on sales receipts. Over 4600 pharmacies provide this information. The purchases of a selection of medicines are used to build a weighted indicator. The algorithms are based on those developed for the flu syndrome IAS® and the® gastro-enteritis IAS, whose reliability was confirmed through a comparison with data from the Sentinel network.

Information is available in the following format:

- Maps showing yesterday's status and progression of seasonal allergies in France over the past 30 days.

- Video showing spatial-temporal changes since 2010.

- A graph of the national temporal series since 2010.

- A graph showing the curve for each region in relation to the national curve.

On maps, the size of each geographical area is proportional to its number of inhabitants (Ile de France is therefore very big, isodemographic representation), the colour is darker when allergies are greater. A Scabies index (in a box on the right of the map) of 100 shows that the level is identical to that in May-June 2009 (reference period). An Allergies index of 180 means there is 80% more scabies than the base level.
