Imagine….„ A person comes to the emergency

department complaining of severe pain. The doctor enters the symptoms into the electronic health record system (EHR) . As the doctor tries to determine what’s causing the pain an alert from the health department pops back up on the screen– public health surveillance data advices that there’s been a salmonella outbreak in the region. The patient receives a proper medication and avoids an overnight stay because of the prompt action.”

We can create useful reminders about prevalence of disease in a community
