Description
Description : The head louse, Pediculus humanus capitis, is an obligate ectoparasite that causes infestations of humans. Studies have demonstrated a correlation between sales figures for over-the-counter (OTC) treatment products and the number of humans with head lice. The deregulation of the Swedish pharmacy market on July 1, 2009, decreased the possibility to obtain complete sale figures and thereby the possibility to obtain yearly trends of head lice infestations. In the presented study we wanted to investigate whether web queries on head lice can be used as substitute for OTC sales figures. Via Google Insights for Search and Va°rdguiden medical web site, the number of queries on ‘‘huvudlo¨ ss’’ (head lice) and ‘‘ha°rlo¨ ss’’ (lice in hair) were obtained. The analysis showed that both the Va°rdguiden series and the Google series were statistically significant (p,0.001) when added separately, but if the Google series were already included in the model, the Va°rdguiden series were not statistically significant (p = 0.5689). In conclusion, web queries can detect if there is an increase or decrease of head lice infested humans in Sweden over a period of years, and be as reliable a proxy as the OTC-sales figures.
