Not to be a "downer" or alarmist as we thoroughly enjoyed our visit to CR, and will return next year. We flew to San Jose, ferry from Punterenas to Nicoya Penninsula and back. My son, on his return flight had terrible headache which I figured was due to our 4 a.m.departure to the airport and little sleep. He later had "shivering" chills, now low grade fever and headaches. I understand in August an outbreak had been reported however we were there last week. He did go to Montezuma ziplining and it rained for a couple of hours right before they left. Have been to docs of course however was wondering if possible to even catch this in this dry season? Thoughts?

i should add he tested negative for influenza A & B

Is it possible to get Dengue in CR? Yes.

No info, but hope he gets well soon.

Have you taken him to a doctor...

Yes, lots of dengue in Costa Rica this year, 4x increase from last year. Guanacaste is one of the focus areas.

Mosquitos breed in pools, so stagnant water from the floods in November might be related?

Check with a doctor!

Yes rare but possible Dengue Epidemic in your areas in fall

Lots of family doctors miss the diagnosis

get the blood test perhaps go to a infectious disease

or travel mediciane specialist...

www.cdc.gov will have info and usually does this testing

Get well soon!

So did your doctor give you a diagnosis? The symptoms that I've read about Dengue usually include a high fever, up to 104, a rash, red eyes, bone pain. If your family doc can't give you a diagnosis, I'd see a specialist.

thanks to all and yes did see doc yesterday who said "not familiar with topical diseases). Blood work was done today- results to follow. If he does have it then it would be a milder form which just has to work it's way through with R&R and liquids. I will also look for a specialist if no improvement after today. This link talks about the outbreak specifically in Costa Rica

Thanks again

There is also a very slight risk of malaria in CR, which can be treated. Onset would be 7 to 9 days from exposure.
