The Need of Thermal Cameras for Corona Virus Screening

Introduction

 Let us first understand what actually Thermal cameras are and for what use they are meant for. The thermal cameras detect the temperature by recognizing different levels of infrared light. This light is invisible to the naked eye but can be felt as heat if the intensity is high enough. These cameras can be used to detect elevated body temperature. If the temperature of the skin especially the corner of the eye and forehead is above the average temperature then the individual may be prescribed for additional screening tests.

What do Thermal Cameras do and how is it needful in the Current COVID-19 Situation

 By using infrared technology, thermal cameras detect radiating heat from a body usually from the forehead and then estimate core body temperature. These cameras are extremely powerful tool mostly used by a firefighter to track smoldering embers and also used by the police to search for out of sight suspects. But they are not designed to be medical devices. They can give a reasonable measure of skin temperature to almost within a half degree but that’s not the same as body temperature. These devices in general are less accurate than medical devices thermometers.

A high temperature is usually considered to be 38C or over it but the normal temperature can vary from person to person and can change during the day. It can also fluctuate during the woman’s monthly cycle. Taking the accurate body temperature isn’t easy though it although it can be measured on the forehead, in the mouth, the ear, and the armpit; the most accurate way is to take a rectal reading.

The thermal cameras don’t detect Corona Virus, they only measure temperature. A high temperature or fever is just one common symptom of the Corona Virus. But not everyone with the virus gets a high temperature and not everyone with high temperature is infected with Corona Virus. So the thermal cameras alone can’t detect infected people with other symptoms or can say no symptoms at all. They can only identify people with fever. Although it doesn’t detect infected COVID-19 patients, they still detect persons with fever and aware of them for further measures. It also helps the health providers to treat the infected patient as early as possible to ensure his safety from coronavirus and save his life. Thermal cameras are already being implemented as a means of detecting people with fever-like symptoms in high traffic areas such as hospitals entrances, shopping centers, and office buildings and potentially mass attendance sporting events when they resume. The people who show up as having high temperatures can then be directed to further treatment and encouraged to isolate to help curb the spread of COVID-19. During these pandemic conditions, the rise of such devices is increasing and also it plays a vital role in the detection of fever. Many hospitals, shopping centers, office buildings, etc have set up such devices for precautions & safety. Precaution is better than cure is the saying and this is very much important to implement in this pandemic situation. So in the COVID-19 condition, the role of thermal cameras is equally important and needed to ensure safety & precaution basis.

Conclusion

To conclude, we can say that Thermal Cameras are effective in detecting people who have a fever i.e. have a higher than normal body temperature but they cannot detect people who are infected with COVID-19. But still, it is needful in this pandemic condition to detect the people with a fever to undergo COVID-19 tests and seek medical guidance from the health providers.
