ZuidWest, I appreciate your apology but I still don't think I deserved such un-necessary judgement from you or the others who attacked me here. Are you Portuguese by the way? I would find it highly ironic if you or the other posters were Portuguese.
As far as your comment that Portugal has better hygiene standards than China, well, that's your subjective opinion. I could easily say that Minnesota has better hygiene standards than New York or Lose Angeles. That's just an opinion. I stayed in hostels and hotels in both England and Ireland when I a little kid, with my family, where the hygiene standards were very sub par.
I don't know why you would be shocked at me for thinking that Malaria exists in Western Europe, when it clearly does. Just read the news. There have been recent Malaria outbreaks in Greece and even in Portugal; as recent as 2012.
There was a scientific study in 2012 by the Institute of Marine Research that studied some wetlands reed beds in Portugal, after 58 cases of Malaria were reported by Portugal's own National Health Service. There's a quote in the article from Nuno Lacasta who warned that rising temperatures in Portugal will increase the risk for more Malaria cases to occur. I found this information online, and I'm not Portuguese.
I am in my 40s and want to be sure I know what to expect when I travel to Portugal. I do plan to have fun and enjoy the Portuguese food and culture, but I don't appreciate being bullied by anonymous posters on a travel forum for the questions I ask. It's immature behavior on those posters part for making assumptions, and treating those assumptions as facts to base their nasty comments on. Malaria could pop up anywhere there is a warm climate and large body of water. Hawaii has Malaria cases all the time and they are a very civilized island that is overrun by tourists all year round.
