Covid-19 has disrupted the lives of millions of people around the globe. It is one of the biggest pandemics in the history of humankind and is spreading fast. It has put almost every person on earth at the risk of getting an infection from another infected person. While doctors and scientists all around the world are trying to find a cure for it, the better way to combat this lethal disease is to take precautions to combat the spread of the disease. No wonder most of the places like airports, stores, offices, restaurants, and many others are following screening procedures such as initial physical checkups using devices like non-contact infrared forehead thermometer, etc. The forehead thermometer is the easiest way to screen the body temperature of an individual entering any premises without making any physical contact with the person. These thermometers are not only accurate but also reliable. However, the CDC (US Centers for Disease Control and Prevention), a temperature check is not a mandatory exercise. They mention it as an optional strategy, which can help reduce the risk of the Corona outbreak. CDC has left this decision to the States whether they want to include a temperature check as a screening procedure. While most authorities have made temperature check a mandatory screening process in all the public places like airports, retail stores, restaurants, etc., others have made it necessary for all the employees entering the office premises. Why is temperature screening important? If a person enters another country or any other place without the temperature check, there are chances that he or she might be carrying coronavirus. Since fever is one of the primary symptoms, it is the most straightforward way to screen a person during the primary assessment anywhere using just a thermometer. However, one inaccurate reading of a thermometer can put many people at risk of getting the Coronavirus infection. Now the efficacy of the temperature check device depends on many factors. Below are some most popular devices that are used to check the fever of an individual effectively.
- Oral Thermometer: Although this thermometer gives the most accurate results, there are several limitations attached to it. Firstly, it is not practical to use it for a massive crowd. And secondly, since Covid-19 spreads through mouth and nose secretions like saliva etc., the oral thermometer will make the situation worse.
- Ear Thermometer: The ear temperature is usually accurate and shows a 0.5°F- 1°F temperature higher than the oral temperature. But it has some discrepancies like ear wax may impact its reading and you might need a new ear-probe jacket for each individual.
- Infrared Thermal Cameras: these are the most accurate temperature screening devices and can be used for a larger crowd at the same time. But these IR cameras are expensive and need proper infrastructural setup. They are usually used in extensive facilities like airports, high-profile businesses, etc.
- Non-Contact Forehead Thermometer: While the Non-Contact forehead thermometer is the next most accurate after the oral thermometer, it is the best way to check the temperature without getting your face closer to the person who is being scanned for Covid-19 symptoms.
