If you travel with children you always have to worry about them getting
ill, and chances of them contracting a cold at any given moment are good
(as anyone with children knows). Heading for a hospital might not be the
best option since emergency rooms are usually crowded and the wait can
be long. For simple and common illness it might be best to visit a private
doctor in the nearest city. The visit would cost a bit more, but the service
is excellent and fast. Ask at a pharmacy or the locals for the best doctor
in town and they will point you the right way. Most doctors speak English
or another language so communication should not be a problem, just make
sure though before you show up.
There is a large children's hospital in Athens, and one in Patra that specializes in children's health matters. Both hospitals receive the bulk of serious illness cases from the entire country, and their medical personnel is as experienced as it gets.
If you do not have insurance, you can get examined at any hospital for about $2 and get first aid attention.
I would recommend having insurance that would cover you even on vacation. Check with your insurance before you fly to Greece to find out if it would cover any medical expenses abroad. Most insurance companies have a policy.
Doctors also like to see the list of vaccines that children have received and any other medical history that is relevant to a chronic problem. Many pediatricians in Greece speak and read English, so it might be a good idea to pack a copy of the list of immunizations your children have received, and any other medical information that could help a Greek doctor in case of an emergency.
