Dr. Darina O'Flanagan:

I agree. As to the question of aid workers returning, it depends on their level of exposure, whether they have been in contact with Ebola cases and whether they have been exposed to bodily fluids. If they have, there will be active monitoring. In other words, public health staff will organise to have them telephoned twice per day to check that they remain asymptomatic. If they have not had high-risk exposures, they will be asked to notify, take their temperatures twice per day, self-monitor and report if they develop fevers. It depends on their level of exposure in the country in question.

As Dr. Holohan stated, we are constantly considering our protocols for contact tracing. We are learning from the experience in the US. We will review that and the experience in Spain to determine whether our protocols need strengthening. In addition, the European Centre for Disease Prevention and Control, ECDC, has guidance on contact tracing and the appropriate steps to take. We follow that guidance closely.
