Thank you for asking your query at DoctorSpring.
No, you need not be concerned. There is NOT even 1 cases of Naegleria Fowleri reported from NewYork state (out of the 128 cases so far in the United States, 0 in NY). http://www.cdc.gov/parasites/naegleria/graphs.html The incidence of N.fowleri is so less in the general population, intact it is not even possible the measure the incidence. You are just being over anxious. Getting water up the nose happens in most swimmers who are in water for more than 15 minutes, even without their awareness. So that is also not an issue. You are probably bit over anxious. There is no need for any concern.
Hope this helps
