How dangerous is the water in terms of the average U.S. pond

This answer was rated:

How dangerous is the water in terms of the average U.S. pond or lake?  Enough to cause severe eye infections?

Anthony Bray MD : Hello!
Anthony Bray MD : While most people may swim on a pond or lake without complications--- there is an increased risk of infections there vs a chlorinated pool for example ....
Anthony Bray MD : The most serious potential is from certain amoeba that can access the nose and infect the brain and may be fatal. There are usually a small number of these annually in the US
Customer:

Right

Customer:

Amoeba was what I was thinking about

Customer:

Amoeba and bacteria affecting the eyes and other organs

Anthony Bray MD : Infections of the eye ---conjunctivitis is common -- much more common but much less serious...
Anthony Bray MD : For this reason I personally favor lakes for fishing or at most wading but pools for swimming!!!
Anthony Bray MD : the statistical risk is not that great but risk of infections are much greater vs the pools that are treated...
Customer:

OK

Customer:

Well, I'm afraid the contact with lake water already happened

Customer:

How long can the germs and amoeba survive out of water?

Customer:

1 week? 1 month?

Anthony Bray MD : I hope this information helps. Let me know if you have further questions and I will be happy to get back with you!
Anthony Bray MD : if my answers have been helpful and to your satisfaction then please remember to leave positive feedback. That would be very much appreciated! Thank you and best regards,

Customer:

Wait, how long can bacteria and amoeba survive out of the lake?

Anthony Bray MD : No an infection would develop within about three days if at all...
Customer:

OK, but there was lake water on clothing, and that hasn't been washed since (weeks ago)

Anthony Bray MD : The survival would depend on the species and the environment of course but I would say that for the vast majority if you go three days without signs if trouble then you would be safe....
Anthony Bray MD : No bacteria would not survive that long on clothing....
Customer:

Amoebas probably wouldn't survive that long either right?

Anthony Bray MD : Right....they would not survive long out of water...
