Primary Outcome Measures

Name	Time	Method
<p>- Incidence of gastrointestinal infections in the general practitioner<br /><br>population and the general population per 1.000 person-years<br /><br>- Prevalence per bacterial, viral and parasitic pathogen in persons visiting<br /><br>the general practitioner with a gastrointestinal infection, and the general<br /><br>population<br /><br>- Risk factors for gastrointestinal infections, as well as pathogen-specific<br /><br>risk factors, in the general practitioner population and the general population<br /><br>- Factors, such as severity of symptoms, that differentiate between persons for<br /><br>which diagnostic testing is requested by the general pracittioner and those for<br /><br>which diagnostics is not requested </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Patients that gave consent to be approached again for future studies could<br /><br>provide insight in the development of sequelae following gastrointestinal<br /><br>infections. The feces databank provides opportunities for gut microbiome<br /><br>research.<br /><br><br /><br></p><br>
