Surveillance and disease control:
From data to intervention
Justin and Katie were married two days ago, a happy day of celebration with their friends and families. After a long day their best man takes them to the airport and they set off for their honeymoon interstate.
During the night they both feel unwell, and while at first they put it down to tiredness and a little too much celebrating, by lunchtime the next day they both have nausea, vomiting and diarrhoea, and resign themselves to a day of staying within reach of the bathroom instead of going on the picnic they had planned.
The next morning Katie's mother phones with the news that quite a lot of their wedding guests are ill, and unfortunately her grandmother and one of her young nieces have been admitted to hospital. Somebody from the health department wants to speak to them.
What do you think the health department staff might want to talk to them about? Do you think the health department should wait until they get back home next week? Are they being too intrusive? What specific questions might they be asking? How might they use the information?
