Myths on virus prevention measures

Myth #1

Hand sanitisers are better than soap

Keeping germs at bay

That’s not true. While hand sanitisers are popular because they do not need rinsing after use, soap is cheaper and equally effective in killing germs and viruses. That is, as long as the soap is fresh and well-kept in a clean container. Old soap bars and those kept in dirty containers may become hotbeds for bacteria, which will subsequently be transferred to the human body when the soap is not rinsed off properly.

Myth #2

All hand sanitisers are safe for human use

Not really — the main ingredient of hand sanitisers is alcohol, which will completely evaporate in less than a minute. However, do not attempt to smell the hand sanitiser before it evaporates, especially those with a fancy scent, as it may contain chemicals that may harm your health or even be flammable.

The Ministry of Health advises using hand sanitisers containing at least 60% to 95% alcohol. High alcohol content, however, could dry out the skin on your hands, which in turn makes it vulnerable to germs.

According to Infection Control Association of Malaysia President Prof Dr Norayati Abd Majid, it is not so much the amount of alcohol in the solution but more importantly, its proper use. Make sure you rub every inch of your hands with it, especially the nail gaps.

Myth #3

Stay in and close the windows

COVID-19 is a highly transmissible disease and it is thought to be airborne. The public is advised to avoid crowded places and stay away from people who show symptoms such as coughing or sneezing.

However, it doesn’t mean people have to stay indoors with their windows closed all the time because indoor air quality plays a crucial role in preventing germs and bacteria.

While products such as air filters, air purifiers and some air-conditioners have the ability to kill germs and destroy viruses, you should not fully rely on them because natural air flow and sunlight are key in keeping indoor air fresh. In addition, such equipment also needs to be regularly cleaned and disinfected.
