‘Don’t Use Your Wrist for Temperature Scanning’- MOH

The Ministry of Health (MOH) is again aware of the public not to use their hands for temperature scanning.

During the press conference, Dr Noor Hisham stressed that the most accurate body temperature readings are obtained from scanning the forehead.
“The temperature reading from body parts other than the forehead is doubtful, so in relation to that,” he explained.
With the opening up of Movement Control Order (MCO) restrictions, having thermal scanners have become a sort of an essential gadget to have in the new normal scenario. From offices, malls and other public places- visitors’ temperature is checked using a contactless thermal scanner pointed at the forehead. Thus, which has become the target area for temperature scans
According to Harian Metro, proposed that the ministry discouraged people from recording their body temperatures by pointing the ‘temperature gun’ at the wrist. Which is quite often to see many people started to apply this inaccurate technique.
In general, the normal human body temperature varies from 36.5°C to 37.5°C, any temperature higher would be considered a fever.
On top of that, Dr Noor Hisham also assured that there have been no reported side effects of scanning the forehead with infrared light. Currently, there are no scientific data that shows temperature scanning device can cause side effects and illness.

Standard Body Temperature Reading at Different Parts of the Body

The correct way to measure body temperature is using the mouth (oral), anus (rectal), armpit (axillary), or ear (tympanic). But the temperature readings vary based on the body parts you used to measure the temperature.

Nonetheless, Medical research has not really ascertained an exact correlation between oral, rectal, ear, armpit, and forehead temperature measurements. Overall, the correlation of temperature results are as follows:

  • The average normal oral temperature is 98.6°F (37°C).
  • A rectal temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.
  • An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.
  • An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.
  • A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

Lastly, it is important for the public to be aware of the accurate way for the measurement of body temperature. As temperature higher than 37.5°C can indicate a sign of fever and infections. And we need to seek medical help immediately if body feeling unwell. Keep practising physical distancing and wash your hands often. Together, we can win the battle against Covid-19.
