I had a bad feeling last week on our flight out to join the Island Escape at Palma. There was much coughing on the plane and I remember saying to my family "It will be a miracle if we don't catch something on this holiday". By the end of the week most of the passengers and crew had hacking coughs. We now have full blown flu, not just a cold. The type where you feel someone is pulling out your teeth with pliers. Where Paracetomol and decongestants make no difference . Silly me didn't have a flu jab this year. Mr hbrac who did have one ,is OK.This epidemic was despite plenty of hand saniters being in use. People were coughing and sneezing without covering their mouths.
So if you are going on this cruise imminently and have a compromised immune system for any reason it might be worth your while getting a flu jab before you go if you have time.
