We thank Mr Kwok Shao Jong for his feedback ("More hand sanitisers at airport can curb spread of disease"; Forum Online, April 28).

We assure Mr Kwok that hand sanitisers are available at all immigration checkpoints across the three terminals, as well as at other places such as lift-waiting areas and Internet kiosks.

We will add more hand sanitisers where appropriate and look at ways to make the hand sanitisers more prominent.
