If knights of old had their armour, healthcare workers of today have their personal protective equipment (PPE).
Just as a knight’s armour protects them against injury in battle, a healthcare worker’s PPE protects them against infection in their battle against dangerous microorganisms.
These pieces of equipment are especially important during times of viral pandemic, like the current Covid-19 outbreak.
The infectiousness of the SARS-CoV-2 virus, which causes Covid-19, and its occasional lack of symptoms, can make it difficult to identify who has the infection.
This means that healthcare workers constantly face the danger of coming into close contact with a patient who might be unknowingly infected with the novel coronavirus.
The only thing protecting them from catching the virus is their PPE.
There is a strict sequence to putting on and taking off PPE, and it requires practice to do it both correctly and quickly.
Any mistakes during the process could mean potential exposure to a dangerous microorganism like SARS-CoV-2.
We take a look at this process as demonstrated by Hospital Canselor Tuanku Muhriz Department of Otorhinolarygology - Head and Neck Surgery medical officer Dr Tan Sui Ting.
