Jet Lag?
 

First time to fly international for our family. I was exhausted right away and after a few days of extra sleep have rebounded. The kids faired well and no complaints. It has been 5 days and now my husband has been hit with extreme exhaustion, aches and low fever. Could this be delayed jet lag?

Sounds more like a case of mild flu.

I agree. It seems highly unlikely he would experience jet lag after 5 days. Nor does jet lag cause a fever.

Get to a pharmacy and ask for the kind of treatments you use at home. Make sure he's hydrating. And a heating pad could help with the aches.

Good luck.

On one trip I experienced jet lag for just over two weeks (going to bed at 6:00 p.m., getting up at 2:00 a.m. and just could not get back into the rhythm). That was very difficult for my job.

However, I did not experience any aches and pains. I agree - it sounds more like flu (perhaps flu and jet lag combined).

That is not jet lag. Not to panic, it may well be simply a viral infection that blossomed in the presence of the stress of travel. (Technically not flu but that term is commonly used in error to refer to a rang of viral infections.) Hydrate, OTC pain reliever as needed, if temp goes over 100.5 F / 38 C seek medical attention.

Thanks for the help, the update is he elt worse after getting up so he went to Dr....light case of pnemonia. So lots of meds and rest it will be....the work will have to wait.
