A kettle does not boil water long enough to disinfect it. Why not put
less
water in the kettle to begin with? If you do this regularly, you should

have
a fair idea of how much water you will need.

===============================
Just to be clear.....

I assume that you mean a kettle with an automatic switch which switches
off
after a few seconds of boiling. Other non-automatic kettles can surely
boil for the 5 minute period mentioned by another poster.


Indeed, but non-electric kettles are very much in the minority and I wonder
whether one with an external heat source would have enough water left to
make a cup of coffee after filling the bowl, then boiling for another five
minutes.

Raising the water to 60 C kills about 95% of the bugs in seconds.
Raising it to 100C kills about 99.999% in about 5 seconds, and 99.99999%
in 5 minutes.

If your immune system can't cope with the odd bug, you had better not go
outside at all. You CERTAINLY should not eat rare beef...
