Question 1

Did I catch it at the pool?

Accepted Answer

It is possible, and it is one of the commonest routes along with shared showers and changing rooms: these are warm, damp surfaces on which the fungus survives. That said, exposure alone is not enough — how long the feet stay damp afterwards and what footwear is used also count. Prevention is therefore not avoiding the pool, but drying thoroughly between the toes and not walking barefoot on those floors.

Question 2

Why does it come back every summer?

Accepted Answer

Because the favouring conditions return, and often because the reservoir was never emptied. The fungus can persist in footwear and, above all, in an affected nail that was never treated: from there the skin is reinfected whenever heat and humidity allow. When recurrences are regular, the right question is not which cream to use but where the fungus hides between episodes.

Question 3

Do I have to throw away my shoes?

Accepted Answer

Not necessarily, but they should be treated as part of the problem and not as a detail. Alternating footwear so it dries between uses, preferring natural-fibre socks and changing them if they become damp, airing sports shoes: these are mundane measures that nonetheless affect recurrence more than patients expect. Specific advice is given at the visit, looking at the footwear you actually use.
