Thermal cameras, which can read heat signatures on people and objects, could be used to help organizations navigate the pandemic and evaluate illness.

However, these cameras don't detect the virus itself, they merely measure whether a person has an elevated skin temperature or not, said Bainter. This means that they aren't a catch-all solution, but rather, could be integrated into a broader public health and safety process involving screening and diagnosis.

Hypothetically, these devices could have many uses for governments. City halls and mayor's offices could identify sick staff before they entered a building; airports could screen passengers to cut down on the likelihood of national or international carriers; and jails and prisons might be able to prevent an outbreak before it occurs.

No, we cannot differentiate COVID-19 disease with another virus disease without a molecular method or specific test.
