Disease Statistics: According to a study published in 2014, all instances of respiratory tract infection or gastroenteritis were studied in Sweden, from September 2011 through May 2012. The study revealed that , picorna- and coronaviruses dominated in specimens obtained from the self-sampling scheme.
