“…During the last decade, space-time cluster detection in the health field has been particularly strong, e.g. for the evaluation of infectious diseases such as tuberculosis (Nunes, 2007), malaria (Magalhaes and Clements, 2011), West Nile virus (Winters et al, 2010), schistosomiasis (Clements et al, 2009), H5N1 avian flu (Souris et al, 2010) and hepatitis A (Gomez-Barroso et al, 2011), among others. Detection methods for space-time clusters refer to the identification of a higher density of event occurrences in certain places at certain times, a dynamic technique essential for the determination of when, where and to what degree a disease is present (Galazka, 1992;Garcia-Corbeira et al, 2000;Dominguez et al, 2001;ez-Domingo et al, 2004;Dempsey et al, 2009).…”
