Covid-19 and the Importance of Temperature Readings

With the widespread screening of the population, whether at work, school, shopping centres or airports, it has become increasingly critical that people understand what is considered to be a normal body temperature and the consequences of getting it wrong.

Normal Temperature

The average normal body temperature is between 36° and 37° Celsius. We’re all different and we all run at different temperatures. Take my daughters for example: my eldest has always run hot. For her, normal is late 36’s and even up to 37.1 on a really hot day. This is her normal. My middle child on the other hand would be coming down with something at 37°C. Her normal is about 36.5°C. So we’re all different, but for the most part, we all fit into that normal average band.

What Happens Outside of the Normal Range?

Quite simply, once the body starts to head past 37.3°C, it’s considered a fever and there could be something brewing in the system. The higher it gets, the harder the immune system is fighting.

Anything below 36°C is considered a cold body temperature and while not considered normal, it is possible to be at a cold temperature for a while. It’s probably because you’re exposed to cold weather or cold water which is affecting your core body temperature.

Once you go below 35°C, you are entering hypothermia.

Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature.

Why am I Stating the Obvious

I’m not sure if people are just simply desperate to show evidence of no fever during these anxious times of Covid-19 screening or if they simply don’t know the basics of body temperature.

Everywhere I go, businesses have invested a lot of money in infrared thermometers, so that they can scan their staff for fevers without having to touch them. There is no place for traditional thermometers these days.

I’ve engaged in a friendly manner with a few owners and so far, most people have temperatures in the late 35’s. One store owner friend had a list of all his staff and they were all in the mid 34’s. Yesterday, I asked a shop owner to test my temperature and she gladly did so, pointing her little gun shaped thermometer at my forehead with pride – she had just purchased the device. My temperature was 35.7°C. I smiled. We chatted a bit and then a few moments later, I ask her to check my temperature again, but I asked her to move the thermometer closed to my forehead. This time my temperature was 36.3°C.

Do You See the Problem Here Folks?

Covid-19 screening will all be for naught if temperatures are not taken correctly. If these infrared thermometers are not used correctly, and are picking up too much ambient temperature, people with real fevers are going to be misdiagnosed. For example, if I’m running a slight fever of 37.3°C and the thermometer is not being used correctly, I could display a temperature of 36-point-something, and the user will be none-the-wiser, and I will pass the screening.

Now imagine these misreadings happening in factories, and mines, schools and shopping centres. Thousands of people could be affected simply because screeners don’t know how to use the thermometer and they don’t realise when a reading is not within the average normal range.

It is VITAL that the thermometers are understood and everyone using them knows how to use them and knows what readings to expect.

Ambium Can Help!

When a temperature is captured into Ambium, it is immediately categorised. The image below shows the categories of fevers as per readings captured.

The operator or screener can then be shown that if the reading is not ‘normal’, he/she needs to retest, perhaps moving closer to the employee’s forehead. Otherwise they should call a supervisor.

Then of course there’s the ‘What the Hell‘ temperature that Ambium simply won’t save because it’s outside of the range, and the employee is actually on the floor, dead. The image below demonstrates the error that the screener will get when trying to save the readings.

Education

People out there who will be screening the nation in their offices, schools, factories and shopping centres need to be properly trained and know how to use the infrared thermometers that they are given. Otherwise, we’re wasting our time with Covid-19 screening.

Ambium will prove a valuable asset in every environment where screening needs to take place.

COVID-19 Screening

As South Africa heads into the unfortunate phase of COVID-19 growth, and with the workforce slowly having to return to work, screening employees before they enter the workplace will be a vital aspect of fighting the pandemic. Technology is a crucial tool in the fight against COVID-19.

Our mining customers are doing their COVID-19 employee screening through Modiri Health. The DMR is very strict on what is required and Ambium provides the technology to put the requirements into practice.

With a good system in place, screening of employees doesn’t need to be an administrative nightmare. With Ambium Cloud, employees can be screened and records captured directly into the system. Plus, the records are also stored in the cloud which makes for easy access from any location.

Employee declarations can be electronically signed if you are required to keep a legal record of the screening. A complete reporting system allows you to provide information on the spot, whether to your manager or to any governing or informational organisation.

Workplace screening was essential to stop the spread.

If your clinic is providing the service of “return-to-work” medicals and daily/weekly screening of the employees of your customers, Ambium Cloud provides the ideal solution. Your mobile clinic can be at any site at any time while you stay in touch with what is happening on the ground.

With Ambium, every employee can be issued with a Certificate
