Question:  Humidifiers are being marketed as effective and childsafe tools to kill Hand, Foot and Mouth disease (HFMD): "Are these devices endorsed and recommended by the local authorities as effective and safe for use around young children? Is there any regulation for such devices and their claims of non-toxicity?

Answer: Humidifiers are not regulated here. They are classed with other consumer electronics like fans and rice cookers. However, any claims that it can prevent the spread of HFMD in a childcare setting is unlikely to be true. This is because the virus is not airborne, but spread through bodily fluids like saliva and urine.

Dr Leong Hoe Nam, an infectious diseases doctor in private practice, said: "The usage of humidifiers may reduce the transmission slightly but it is inconsequential. It might be effective if the humidifier is placed within close proximity. However, practically, it may not be sufficient to prevent transmission. The key to prevention is to maintain good hand hygiene, avoid contact with fluid-filled blisters, and discourage sharing of drinks and toys especially among the young children."

The best way to prevent the spread of the disease is for parents to keep their sick children at home and away from other kids. When the child has recovered, he might still have the virus, but is very much less contagious.

There are currently three childcare centres with active clusters: Sweetlands Childcare Woodlands 886C, Our Juniors Schoolhouse @ Choa Chu Kang, and St Andrews Cathedral Child Development Centre.
