How can you tell if someone is infected with the COVID-19 virus? This virus is especially difficult to spot since you can be a carrier without showing too many symptoms. One of the common symptoms is a fever, and thermal imaging actually helps in finding those that have an elevated body temperature.
This is why thermal imaging has seen quite some use around the world in efforts to prevent the spread of the disease. You will see this implemented at airports where they can pinpoint travelers that have an elevated body temperature and possibly needing to be quarantined. Police in some countries have used it to find people that are outside, spreading contamination. It is even used in hospitals to get an early warning of patients that enter the emergency room who need to be separated from everyone else. Overall, thermal imaging can provide early information on the body temperature of people without even approaching them, and that is good news for those that want to prevent the spread of the Coronavirus.
